General

Our operating subsidiariessub sidiaries acquire, develop, license and enforce patented technologies.  Our operating subsidiaries generate license fee revenues and related cash flows from the granting of licensesintellectual property rights for the use of patented technologies that our operating subsidiaries own or control.  Our operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, if necessary, with the enforcement against unauthorized users of their patented technologies.

We are a leader in licensing patented technologies and have established a proven track record of licensing success with over 620960 license agreements executed to date, across 4891 of our technology license programs.  Currently, on a consolidated basis, our operating subsidiaries own or control the rights to over 100171 patent portfolios, which include U.S. patents and certain foreign counterparts covering technologies used in a wide variety of industries.

CombiMatrix Group Split-Off Transaction and Related Discontinued Operations.  In January 2006, our board of directors approved a plan for our former wholly owned subsidiary, CombiMatrix Corporation, or CombiMatrix, the primary component of our life science business, known as the CombiMatrix group, to become an independent publicly-held company.  On August 15, 2007, or the Redemption Date, CombiMatrix was split-off from us through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock in exchange for the distribution of new shares of CombiMatrix common stock, on a pro-rata basis, to the holders of Acacia Research-CombiMatrix common stock on the Redemption Date.  We refer to this transaction as the Split-Off Transaction.  Subsequent to the Redemption Date, we no longer own any equity interests in CombiMatrix and the CombiMatrix group is no longer one of our business groups.  Subsequent to the Split-Off Transaction, our only business is our intellectual property licensing business.
Refer to Note 10A to our consolidated financial statements, included elsewhere herein, for information regarding presentation of the assets, liabilities, results of operations and cash flows for the CombiMatrix group as “Discontinued Operations,” for all periods presented, in accordance with guidance set forth in Statement of Financial Accounting Standards (“SFAS”) No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets,” or SFAS No. 144.

Capital Structure.  Pursuant to the terms of the Split-Off Transaction, all outstanding shares of Acacia Research-CombiMatrix common stock were redeemed, and all rights of holders of Acacia Research-CombiMatrix common stock ceased as of the Redemption Date, except for the right, upon the surrender to the exchange agent of shares of Acacia Research-CombiMatrix common stock, to receive new shares of CombiMatrix common stock.  As a result of, and immediately following, the consummation of the Split-Off Transaction, our only class of common stock outstanding was our Acacia Research-Acacia Technologies common stock.
On May 20, 2008, our stockholders approved an amendment and restatement of our Certificate of Incorporation to eliminate all references to Acacia Research-CombiMatrix common stock and all provisions relating to the rights and obligations of the Acacia Research-CombiMatrix common stock.  In addition, the amendment and restatement changed the name of the “Acacia Research-Acacia Technologies common stock” to “common stock,” and our common stock is the only class of common stock authorized and issuable.

BUSINESS OVERVIEW

Intellectual Property Licensing Business

Our operating subsidiaries acquire, develop, license and enforce patented technologies.  Our operating subsidiaries generate license fee revenues and related cash flows from the granting of licensesintellectual property rights for the use of patented technologies that our operating subsidiaries own or control.  Our operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, if necessary, with the enforcement against unauthorized users of their patented technologies. Currently, on a consolidated basis, our operating subsidiaries own or control the rights to over 100171 patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.  Refer to the section entitled “Patented Technologies” below for a partial summary of patent portfolios owned or controlled by certain of our operating subsidiaries.
We are a leader in patent licensing and our operating subsidiaries have established a proven track record of licensing success with more than 620960 license agreements executed to date.&nbs p; To date, on a consolidated basis, we have generated revenues from 4891 of our technology licensing and enforcement programs.  Our professional staff includes in-house patent attorneys, licensing executives, engineers and business development executives.

Our partners are primarilyinclude individual inventors and small technology companies who have limited resources and/or expertise to effectively address the unauthorized use of their patented technologies, and also include research laboratories, universities, and large companies seeking to effectively and efficiently monetize their portfolio of patented technologies. In a typical partnering arrangement, our operating subsidiary will acquire a patent portfolio or acquire rights to a patent portfolio, withand in exchange, our partner receivingreceives (i) an upfront payment for the purchase of the patent portfolio or patent portfolio rights, or receiving(ii) a percentage of our operating subsidiariessubsidiary's net recoveries from the licensing and enforcement of the patent portfolio, or (iii) a combination of the two.

Under U.S. law, an inventor or patent owner has the right to exclude others from making, selling or using their patented invention. Unfortunately, in the majority of cases, infringers are generally unwilling, at least initially, to negotiate or pay reasonable royalties for their unauthorized use of third-party patents and will typically fight any allegat ions of patent infringement.  Inventors and/or patent holders without sufficient legal, financial and/or expert technical resources to bring and continue the pursuit of legal action may lack credibility in dealing with unwilling licensees, and as a result, are often blatantly ignored.
As a result of the common reluctance of patent infringers to negotiate and ultimately take a patent license for the use of third-party patented technologies without at least the threat of legal action, patent licensing and enforcement often begins with the filing of patent enforcement litigation.  However, the majority of patent infringement contentions settle out of court, based on the strength of the patent claims, validity, and persuasive evidence and clarity that the patent is being infringed.
We execute patent licensing and intellectual property rights arrangements with users of our patented technologies through willing negotiations without the filing of patent infringement litigation, or through the negotiation of a patent license, intellectual property rights and settlement arrangements in connection with the filing of patent infringement litigation.

Business Model and Strategy - Overview

The business model associated with the licensing and enforcement activities conducted by our operating subsidiaries is summarized in the following diagram:illustration:

Licensing and Enforcement Business

Key Elements of Business Strategy
Our intellectual property acquisition, development, licensing and enforcement business strategy, conducted solely by our operating subsidiaries, includes the following key elements:

●  
•    Identify Emerging Growth Areas where Patented Technologies will Play a Vital Role

The patent process breeds, encourages and sustains innovation and invention by granting a limited monopoly to the inventor in exchange for sharing the invention with the public. Certain technologies, including several of the technologies controlled by our operating subsidiaries, some of which are summarized below, become core technologies in the way products and services are manufactured, sold and delivered by companies across a wide array of industries.  Our operating subsidiaries identify core, patented technologies that have been or are anticipated to be widely adopted by third parties in connection with the manufacture or sale of products and services.

●  
•    Contact and Form Alliances with Owners of Core, Patented Technologies

Often individual inventors and small companies have limited resources and/or expertise and are unable to effectively address the unauthorized use of their patented technologies.  Individual inventors and small companies may lack sufficient capital resources and may also lack in-house personnel with patent licensing and/or enforcement expertise or experience, which may make it difficult to effectively and efficiently out-license and/or enforce their patented technologies.
Often individual inventors and small companies have limited resources and/or expertise and are unable to effectively address the unauthorized use of their patented technologies.  Individual inventors and small companies may lack sufficient capital resources and may also lack in-house personnel with patent licensing expertise and/or experience, which may make it difficult to effectively out-license and/or enforce their patented technologies.

For years, many large companies have earned substantial revenue licensing patented technologies to third parties.  Other companies that do not have internal licensing resources and expertise may have continued to record the capitalized carrying value of their core and/or non-essential intellectual property in their financial statements, without deriving income from their intellectual property or realizing the potential value of their intellectual property assets.  Securities and financial reporting regulations require these companies to periodically evaluate and potentially reduce or write-off these intellectual property assets if they are unable to substantiate these rep orted carrying values.

Our operating subsidiaries seek to enter into business agreements with owners of intellectual property that do not have

experience or expertise in the areas of intellectual property licensing and enforcement, or that do not possess the in-house resources to devote to intellectual property licensing and enforcement activities, or that, for any number of strategic business reasons, desire to more efficiently and effectively outsource their intellectual property licensing and enforcement activities.

●  
•    Effectively and Efficiently Evaluate Patented Technologies for Acquisition, Licensing and Enforcement

Subtleties in the language of a patent, recorded interactions with the patent office, and the evaluation of prior art and literature can make a significant difference in the potential licensing and enforcement revenue derived from a patent or patent portfolio.  Our specialists are trained and skilled in these areas.  It is important to identify potential problem areas, if any, and determine whether potential problem areas can be overcome, prior to acquiring a patent portfolio or launching an effective licensing program.  We have developed processes and procedures for identifying problem areas and evaluating the strength of a patent p ortfolio before the decision is made to allocate resources to an acquisition or to launch an effective licensing and enforcement effort.
Patent Portfolio Evaluation.  The processes and procedures employed in connection with the evaluation of a specific patent portfolio for acquisition, licensing and enforcement are tailored and unique to each specific situation, and can vary widely based on the specific facts and circumstances of a specific patent portfolio, technology, related industry and certain other factors.  Some of the key components of our processes and procedures may include:
Subtleties
•    Utilizing our staff of in-house intellectual property business development executives, patent attorneys, intellectual property licensing executives, and technology engineers to conduct our tailored patent acquisition and evaluation processes and procedures.  We may also leverage the expertise of external specialists and technology consultants.
•    Identifying emerging growth areas where patented technologies will play a vital role in connection with the manufacture or sale of products and services.
•    Identifying core, patented technologies that have been or are anticipated to be widely adopted by third parties in connection with the manufacture or sale of products and se rvices.
•    Considering the impact of subtleties in the language of a patent, recorded interactions with the patent office, and the evaluation ofevaluating prior art and literature can make a significant difference inand considering the impact on the potential licensing and enforcement revenue that can be derived from a patent or patent portfolio.  Our specialists are trained and skilled in these areas.  It is important to identify potential problem areas, if any, and determine whether potential problem areas can be overcome, prior to acquiring a patent portfolio or launching an effective licensing program.  We have developed processes and procedures for identifying problem areas and evaluating

●  
Purchase
•    Identifying and considering potential problem areas, if any, and determining whether potential problem areas can be overcome prior to acquiring a patent portfolio or Acquire the Rights to Patented Technologieslau nching an effective licensing program.

After evaluation, our operating subsidiaries may elect to purchase the patented technology, or become the exclusive licensing agent for the patented technology in all or in specific fields of use.  In either case, the owner of the patent generally retains the rights to a portion of the net revenues generated from a patent’s licensing and enforcement program.  Our operating subsidiaries generally control the licensing and enforcement process and utilize experienced in-house personnel to reduce outside costs and to ensure that the necessary capital and expertise is allocated and deployed in an efficient and cost effective manner.

●  
•    
Successfully License and Enforce Patents with Significant Royalty Potential

As part of the patent evaluation process employed by our operating subsidiaries, significant consideration is also given to the identification ofIdentifying potential infringers, industries within which the potential infringers exist, longevity of the patented technology, and a variety of other factors that directly impact the magnitude and potential success of a licensing and enforcement program.  Our specialists are trained in evaluating potentially infringing technologies
•    Purchase or Acquire the Rights to Patented Technologies
After evaluation, our operating subsidiaries may elect to purchase the patented technology, or acquire the exclusive right to license the patented technology in all or in specific fields of use.  In either case, the original owner of the patent or patent rights generally retains the rights to a portion of the net revenues generated from a patent portfolio’s licensing and enforcement program.  Our operati ng subsidiaries generally control the licensing and enforcement process and utilize experienced in-house personnel to reduce outside costs and to ensure that the necessary capital and expertise is allocated and deployed in an efficient and cost effective manner.

Acacia Intellectual Property Fund, L.P.
In August 2010, one of our wholly-owned subsidiaries became the general partner of the Acacia Intellectual Property Fund, L.P., or the Acacia IP Fund, which was formed in August 2010. The Acacia IP Fund is authorized to raise up to $250 million. The Acacia IP Fund acquires, licenses and enforces intellectual property consisting primarily of pate nts, patent rights, and patented technologies.
 
Patent Enforcement Litigation

Our operating subsidiaries are often required to engage in litigation to enforce their patents and patent rights.  Certain of our operating subsidiaries are parties to ongoing patent enforcement related litigation, alleging infringement by third parties of certain of the patented technologies owned or controlled by our operating subsidiaries.

Competition
 
Competition

We expect to encounter increased competition in the area of patent acquisitions and enforcement.  This includes an increase in the number of competitors seeking to acquire the same or similar patents and technologies that we may seek to acquire.  Entities including Allied Security Trust, Altitude Capital Partners, Coller IP, Intellectual Ventures, Millennium Partners, Open Innovation Network, RPX Corporation and Rembrandt IP Management compete in acquiring rights to patents, and we expect more entities to enter the market.

We also compete with venture capital firms, strategic corporate buyers and various industry leaders for technology acquisitions and licensing opportunities.  Many of these competitors may have more financial and human resources than our operating subsidiaries.  As we become more successful, we may find more companies entering the market for similar technology opportunities, which may reduce our market share in one or more technology industries that we currently rely upon to generate future revenue.
 
Other companies may develop competing technologies that offer better or less expensive alternatives to our patented technologies that we may acquire and/or out-license.  Many potential competitors may have significantly greater resources than the resources that our operating subsidiaries possess.  Technological advances or entirely different approaches developed by one or more of our competitors could render certain of the technologies owned or controlled by our operating subsidiaries obsolete and/or uneconomical.
 
Employees

OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO EXPAND OUR ORGANIZATION TO MATCH THE GROWTH OF OUR SUBSIDIARIES.subsidiaries.
 
As our operating subsidiaries grow, the administrative demands upon us and on our operating subsidiaries will grow, and our success will depend upon our ability to meet those demands. These demands include increased accounting, management, legal services, staff support, and general office services. We may need to hire additional qualified personnel to meet these demands, the cost and quality of which is dependent in part upon marketmarke t factors outside of our control. Further, we will need to effectively manage the training and growth of our staff to maintain an efficient and effective workforce, and our failure to do so could adversely affect our business and operating results.
 
OUR REVENUES WILL BE UNPREDICTABLE, AND THIS MAY HARM OUR FINANCIAL CONDITION.

Our revenues will be unpredictable, and this may harm our financial condition.
From January 2005 to present, certain of our operating subsidiaries have continued to execute our business strategy in the area of acquiring patent portfolioportfolios and accompanying patent portfolio rights acquisitions.rights.  Currently, on a consolidated basis, our operating subsidiaries own or control the rights to over 100171 patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.  These acquisitions continue to expand and diversify our revenue generating opportunities. We believe that our cash, cash equivalents and cash equivalentinvestment balances, anticipated cash flow from operations and other external sources of available credit, will be sufficient to meet our cash requirements through at least March 2010,2012 and for the foreseeable future.  However, due to the nature of our licensing business and uncertainties regarding the amountamou nt and timing of the receipt of license fees from potential infringers, stemming primarily from uncertainties regarding the outcome of enforcement actions, rates of adoption of our patented technologies, the growth rates of our existing licensees and certain other factors, we cannot currently predict the amount and timing of the receipt of license fee revenues with a sufficient degree of precision.
As a result, our revenues may vary significantly from quarter to quarter, which could make our business difficult to manage, adversely affect our business and operating results, cause our quarterly results to befall below market expectations. If this happens,expectations and adversely affect the market price of our common stock may decline significantly.stock.

We cannot be certain thatOur current or newfuture relationships willmay not provide the volume or quality of technologies necessary to sustain our business.  In some cases, universities and other technology sources may compete against us as they seek to develop and commercialize technologies.  Universities may receive financing for basic research in exchange for the exclusive right to commercialize resulting inventions.  These and other strategies may reduce the number of technology sources and potential clients to whom we can market our services.  If we are unable to secure newmaintain current relationships and sources of technology it couldor to secure new relationships and sources of technology, such inability may have a material adverse effect on our operating results and financial condition.
 
THE SUCCESS OF OUR OPERATING SUBSIDIARIES DEPENDS IN PART UPON THEIR ABILITY TO RETAIN THE BEST LEGAL COUNSEL TO REPRESENT THEM IN PATENT ENFORCEMENT LITIGATION.The success of our operating subsidiaries depends in part upon their ability to retain the best legal counsel to represent them in patent enforcement litigation.
 
The success of our licensing business depends upon our operating subsidiaries’subsidiaries' ability to retain the best legal counsel to prosecute patent infringementinfringe ment litigation. As our operating subsidiaries’subsidiaries' patent enforcement actions increase, it will become more difficult to find the best legal counsel to handle all of our cases because many of the best law firms may have a conflict of interest that prevents itstheir representation of our subsidiary companies.subsidiaries.

From time to time, our operating subsidiaries may rely upon representations and warranties made by third parties from whom certain of our operating subsidiaries acquired patents or the exclusive rights to license and enforce patents. We also may rely upon the opinions of purported experts.  In certain instances, we may not have the opportunity to independently investigate and verify the facts upon which such representations, warranties, and opinions are made.

OUR INVESTMENTS IN AUCTION RATE SECURITIES ARE SUBJECT TO RISKS, INCLUDING THE CONTINUED FAILURE OF FUTURE AUCTIONS, WHICH MAY CAUSE US TO INCUR LOSSES OR HAVE REDUCED LIQUIDITY.Our investments in auction rate securities are subject to risks, including the continued failure of future auctions, which may cause us to incur losses or have reduced liquidity.
 
At December 31, 2008,2010, our investments in marketable securities includeincluded certain auction rate securities. Our auction rate securities are investment grade quality and were in compliance with our investment policy when purchased.  Historically, our auction rate securities were recorded at cost, which approximated their fair market value due to their variable interest rates, which typically reset every 7 to 35 days, despite the long-term nature of their stated contractual maturities.  The Dutch auction process that resets the applicable interest rate at predetermined calendar intervals is intended to provide liquidity to the holder of auction rate securities by matching buyers and sellers within a market context, enabling the holder to gain immediate liquidity by selling such interests at par or by rolling over their investment. IfI f there is an imbalance between buyers and sellers, the risk of a failed auction exists.  Due to recent liquidity issues in the global credit and capital markets, these securities experienced several failed auctions since February 2008.  In suchthe case of a failure, the auction rate securities continue to pay interest, at the maximum rate, in accordance with their terms,terms; however, we may not be able to access the par value of the invested funds until a future auction of these investments is successful, the security is called by the issuer or a buyer is found outside of the auction process.

At December 31, 2008,2010, the par value of our auction rate securities collateralized by student loan portfolios totaled $2.75$2.5 million. As a result of the liquidity issues associated with the failed auctions, we estimate that the fair value of these auction rate securities no longer approximates their par value.  Due to the estimate that the market for these student loan collateralized instruments may take in excess of twelve months to fully recover, we have classified these investments as noncurrent in the accompanying December 31, 2008 consolidated balance sheet.sheets. In addition, as a result of our analysis of the estimated fair value of our student loan collateralized instruments as described at Note 7 to the consolidated financial statements included elsewhere herein, we have recorded an other-than-temporary loss of $250,000 for our student loan collateralized instruments$296,000 and $263,000 in the accompanying consolidated statementstatements of operations and comprehensive income (loss) (hereinafter “consolidated statements of operations”) for the yearyears ended December 31, 2008.
At December 31,2009 and 2008, we also held auction rate securities withrespectively.  As a result of partial redemptions at par value totaling $975,000, issued by high credit quality closed-end investment companies.  Despite the reduction in liquidity resulting from the failure of auctions for these securities since February 2008, the issuers ofon certain o f these auction rate securities have redeemed, at par, approximately 66%subsequent to June 30, 2008, we recorded net realized gains totaling $32,000, $13,000 and $13,000 for 2010, 2009 and 2008, respectively, reflecting a partial recovery of the securities held by us since February 2008, and have indicated that they continue to evaluate ways to provide additional liquidity to their auction rate security holders.  Additionally,other-than-temporary loss originally recorded on these securities continue to be AAA rated andsecurities.  As of December 31, 2010, the underlying funds continue to meet certain specified asset coverage tests required by the rating agencies, as well as the 200% asset coverage test with respect tonet other-than-temporary loss on auction rate securities set forth in the Investment Company Act of 1940, as amended.  However, due to the impact of the reduced liquidity associated with these securities as of December 31, 2008, we recorded an other-than-temporary loss on these auction rate securities of $236,000 in the accompanying consolidated statement of operations for the year ended December 31, 2008, and have classified our auction rate securities issuedcollateralized by closed-end investment companies as noncurrent assets in the accompanying December 31, 2008 consolidated balance sheet.student loan portfolios totaled $484,000.
 
The capital and credit markets have been experiencing extreme volatility and disruption for more than 12 months.  In recent weeks,24 months, and at times, the volatility and disruption have reachedrea ched unprecedented levels. In several cases, the markets have exerted downward pressure on stock prices and credit capacity for certain issuers.  Given the deteriorating credit markets, and the sustained incidence of failure within the auction market since February 2008, there canwe may be no assurance as to when we would be ableunable to liquidate a particular issue.  Furthermore, although market conditions have shown some sign of improvement, if these market conditions were to persist despite our ability to hold such investments until maturity,further deteriorate, we may be required to record additional impairment charges in a future period.period despite our ability to hold such investments until maturity.  The systemic failure of future auctions for auction rate securities may result in a loss of liquidity, substantial impairment to our investments, realization of substantial future losses, or a complete loss of the investment in the long-term which may have a material adverse effect on our business, results of operations, liquidity, and financial condition.

RISKS RELATED TO OUR INDUSTRYRisks Related to Our Industry
 
BECAUSE OUR BUSINESS OPERATIONS ARE SUBJECT TO MANY UNCONTROLLABLE OUTSIDE INFLUENCES, WE MAY NOT SUCCEED.Our exposure to uncontrollable outside influences, including new legislation, court rulings or actions by the United States Patent and Trademark Office, could adversely affect our licensing and enforcement business and results of operations.
 
Our licensing and enforcement business operations areis subject to numerous risks from outside influences, including the following:
 
New legislation, regulations or rules related to obtaining patents or enforcing patents could significantly increase our operating costs and decrease our revenue.
 
Our operating subsidiaries acquire patents with enforcement opportunities and are spending a significant amount of resources to enforce those patents. If new legislation, regulations or rules are implemented either by Congress, the U.S. Patent and Trademark Office, or USPTO, or the courts that impact the patent application process, the patent enforcement process or the rights of patent holders, these changes could negatively affect our expenses and revenue. For example, new rules regarding

11


the burden of proof in patent enforcement actions could significantly increase the cost of our enforcement actions, and new standards or limitations on liability for patent infringement could negatively impact our revenue derived from such enforcement actions.
 
9

Trial judges and juries often find it difficult to understand complex patent enforcement litigation, and as a result, we may need to appeal adverse decisions by lower courts in order to successfullysuccessf ully enforce our patents.
 
It is difficult to predict the outcome of patent enforcement litigation at the trial level. It is often difficult for juries and trial judges to understand complex, patented technologies, and as a result, there is a higher rate of successful appeals in patent enforcement litigation than more standard business litigation. Such appeals are expensive and time consuming, resulting in increased costs and delayed revenue. Although we diligently pursue enforcement litigation, we cannot predict with significant reliability the decisions made by juries and trial courts.
 
More patent applications are filed each year resulting in longer delays in getting patents issued by the USPTO.
 
Certain of our operating subsidiaries hold and continue to acquire pending patents. We have identified a trend of increasing patent applications each year, which we believe is resulting in longer delays in obtaining approval of pending patent applications. The application delays could cause delays in recognizing revenue from these patents and could cause us to miss opportunities to license patents before other competing technologies are developed or introduced into the market. See the subheading “Competition is intense in the industries in which our subsidiaries do business and as a result, we may not be able to grow or maintain our market share for our technologies and patents,” below.
 
Federal courts are becoming more crowded, and as a result, patent enforcement litigation is taking longer.
 
Our patent enforcement actions are almost exclusively prosecuted in federal court. Federal trial courts that hear our patent enforcement actions also hear criminal cases. Criminal cases always take priority over our actions. As a result, it is difficult to predict the length of time it will take to complete an enforcement action. Moreover, we believe there is a trend in increasingincre asing numbers of civil lawsuits and criminal proceedings before federal judges, and as a result, we believe that the risk of delays in our patent enforcement actions will have a greater affect on our business in the future unless this trend changes.
 
Any reductions in the funding of the USPTO could have an adverse impact on the cost of processing pending patent applications and the value of those pending patent applications.
 
The assets of our operating subsidiariessubsi diaries consist of patent portfolios, including pending patent applications before the USPTO. The value of our patent portfolios is dependent upon the issuance of patents in a timely manner, and any reductions in the funding of the USPTO could negatively impact the value of our assets. Further, reductions in funding from Congress could result in higher patent application filing and maintenance fees charged by the USPTO, causing an unexpected increase in our expenses.
 
Competition is intense in the industries in which our subsidiaries do business and as a result, we may not be able to grow or maintain our market share for our technologies and patents.
 
We expect to encounter competition in the area of patent acquisition and enforcement as the number of companies entering this market is increasing. This includes competitors seeking to acquire the same or similar patents and technologies that we may seek to acquire. Entities including Allied Security Trust, Altitude Capital Partners, Coller IP, Intellectual Ventures, Millennium Partners, Open Innovation Network, RPX Corporation and Rembrandt IP Management compete in acquiring rights to patents, and we expect more entities to enter the market. As new technological advances occur, many of our patented technologies may become obsolete before they are completely monetized. If we are unable to replace obsolete technologies with more technologically advanced patented technologies, then this obsolescence could have a negative effect on our ability to generate future revenues.
 
Our licensing business also competes with venture capital firms and various industry leaders for technology licensing opportunities.  Many of these competitors may have more financial and human resources than our company.we do.  As we become more successful, we may find more companies entering the market for similar technology opportunities, which may reduce our market share in one or more technology industries that we currently rely upon to generate future revenue.
 
10

Our patented technologies face uncertain market value.
 
Our operating subsidiaries have acquired patents and technologies that are atin the early stages of adoption in the commercial and consumer markets. Demand for some of these technologies is untested and is subject to fluctuation based upon the rate at which our licensees will adopt our patents and technologies in their products and services. Refer to the related risk factor below.

12


 
As patent enforcement litigation becomes more prevalent, it may become more difficult for us to voluntarily license our patents.
 
We believe that the more prevalent patent enforcement actions become, the more difficult it will be for us to voluntarily license our patents. As a result, we may need to increase the number of our patent enforcement actions to cause infringing companies to license the patent or pay damages for lost royalties. This may increase the risks associated with an investment in our company.
 
The foregoing outside influences may affect other risk factors described in this annual report.
Any one of the foregoing outside influences may causemarkets served by our companyoperating subsidiaries are subject to need additional financingrapid technological change, and if our operating subsidiaries are unable to meet the challenges presented ordevelop and acquire new technologies and patents, our ability to compensate for a loss in revenue, and we may notgenerate revenues could be able to obtain the needed financing. See the heading “substantially impairedIf we, or our subsidiaries, encounter unforeseen difficulties and cannot obtain additional funding on favorable terms, our business may suffer.” above.
THE MARKETS SERVED BY OUR OPERATING SUBSIDIARIES ARE SUBJECT TO RAPID TECHNOLOGICAL CHANGE, AND IF OUR OPERATING SUBSIDIARIES ARE UNABLE TO DEVELOP AND ACQUIRE NEW TECHNOLOGIES AND PATENTS, ITS REVENUES COULD STOP GROWING OR COULD DECLINE.
 
The markets served by our operating subsidiaries’subsidiaries' licensees frequently undergo transitions in which products rapidly incorporate new features and performance standards on an industry-wide basis. Products for communications applications, high-speed computing applications, as well as other applications covered by our operating subsidiaries’subsidiaries' intellectual property, are based on continually evolving industry standards. Our ability to compete in the future will, however, depend on our ability to identify and ensure compliance with evolving industry standards. This will require our continued efforts and success ofin acquiring new patent portfolios with licensing and enforcement opportunities. However,While we expect for the foreseeable future to have sufficient liquidity and capital resources for the foreseeable future in orderresour ces needed to maintain the level of acquisitions we believe we neednecessary to keep pace with these technological advances. However,advances, outside influences may cause the need for greater liquidity and capital resources than expected, as described under the caption “Becauseabove. If we are unable to acquire new technologies and related patent portfolios, or to identify and ensure compliance with evolving industry standards, our ability to generate revenues could be substantially impaired and our business operations are subject to many uncontrollable outside influences, we may not succeed” above.and financial condition could be materially harmed.
 
THE RECENT FINANCIAL CRISIS AND CURRENT UNCERTAINTY IN GLOBAL ECONOMIC CONDITIONS COULD NEGATIVELY AFFECT OUR BUSINESS, RESULTS OF OPERATIONS, AND FINANCIAL CONDITIONThe recent financial crisis and current uncertainty in global economic conditions could negatively affect our business, results of operations and financial condition.
 
Our revenue-generating opportunities depend on the use of our patented technologies by existing and prospective licensees, the overall demand for the products and services of our licensees, and on the overall economic and financial health of our licensees. The recentDespite showing some signs of improvement, the financial crisis affecting the banking system and financial markets and the current uncertainty in global economic conditions have resulted in a tightening in the credit markets, a low level of liquidity in many financial markets, and extreme volatility in the credit, equity and fixed income markets. If the current worldwide economic downturn continues, many of our licensees’licensees' customers, which may rely on credit financing,fina ncing, may delay or reduce their purchases of our licensees’licensees' products and services.  In addition, the use or adoption of our patented technologies is often based on current and forecasted demand for our licensees’licensees' products and services in the marketplace and may require companies to make significant initial commitments of capital and other resources.  If the negative conditions in the global credit markets delay or prevent our licensees’licensees' and their customers’customers' access to credit, overall consumer spending on the products and services of our licensees may decrease and the adoption or use of our patented technologies may slow, respectively.  Further, if the markets in which our licensees’licensees' participate experience further economic downturns, as well asor a slow recovery period, this could negatively impact our licensees’licensees' long-term sales and revenue generation, margins and operating expenses, which could impact the magnitude of revenues generated or projected to be generated by our licensees, which couldcou ld have a material impact on our business, license feerevenue generating opportunities, operating results and financial condition.
 
11

In addition, we have significant patent relatedpatent-related intangible assets recorded on our consolidated balance sheet.sheets. We will continue to evaluate the recoverability of the carrying amount of our patent relatedpatent-related intangible assets on an ongoing basis, and we may incur substantial impairment charges, which would adversely affect our consolidated financial results. There can be no assurance that the outcome of such reviews in the future will not result in substantial impairment charges. Impairment assessment inherently involves judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact our assumptions as to prices, costs, holding periods or other factors that may result in changes in our estimates of future cash flows. Although we believe the assumptions we used in testing for impairment are reasonable, significant changes in any one of our assumptions could produce a significantly different result.
 
RISKS RELATED TO OUR COMMON STOCK
 
THE AVAILABILITY OF SHARES FOR SALE IN THE FUTURE COULD REDUCE THE MARKET PRICE OF OUR COMMON STOCK.

13


Risks Related to Our Common Stock
The availability of shares for sale in the future could reduce the market price of our common stock.
 
In the future, we may issue securities to raise cash for operations and or acquisitions. We may also pay for interests in additional subsidiary companies by using shares of our common stock or a combination of cash and our common stock or justshares of our common stock. We may also issue securities convertible into our common stock. Any of these events may dilute stockholdersstockhol ders' ownership interestinterests in our company and have an adverse impact on the price of our common stock.
 
In addition, sales of a substantial amount of our common stock in the public market, or the perception that these sales may occur, could reduce the market price of our common stock. This could also impair our ability to raise additional capital through the sale of our securities.
 
DELAWARE LAW AND OUR CHARTER DOCUMENTS CONTAIN PROVISIONS THAT COULD DISCOURAGE OR PREVENT A POTENTIAL TAKEOVER OF OUR COMPANY THAT MIGHT OTHERWISE RESULT IN OUR STOCKHOLDERS RECEIVING A PREMIUM OVER THE MARKET PRICE OF THEIR SHARES.Delaware law and our charter documents contain provisions that could discourag e or prevent a potential takeover of our company that might otherwise result in our stockholders receiving a premium over the market price of their shares.
 
Provisions of Delaware law and our certificate of incorporation and bylaws could make the following more difficult: the acquisition of our company by means of a tender offer, proxy contest or otherwise, and the removal of incumbent officers and directors.directors, more difficult. These provisions include:
 
    Section 203 of the Delaware General Corporation Law, which prohibits a merger with a 15%-or-greater stockholder, such as a party that has completed a successful tender offer, until three years after that party became a 15%-or-greater stockholder;
 
    amendment of our bylaws by the stockholders requires a two-thirds approval of the outstanding shares;
  
●    
•    the authorization in our certificate of incorporation of undesignated preferred stock, which could be issued without stockholder approval in a manner designed to prevent or discourage a takeover;
  
    provisions in our bylaws eliminating stockholders’stockholders' rights to call a special meeting of stockholders, which could make it more difficult for stockholders to wage a proxy contest for control of our board of directors or to vote to repeal any of the anti-takeover provisions contained in our certificate of incorporation and bylaws; and
  
    the division of our board of directors into three classes with staggered terms for each class, which could make it more difficult for an outsider to gain control of our board of directors.
Together these provisions may make the removal of management more difficult and may discourage transactions that could otherwise involve payment of a premium over prevailing market prices for our common stock.

AS A RESULT OF THE REDEMPTION OF ACACIA RESEARCH-COMBIMATRIX COMMON STOCK FOR THE COMMON STOCK OF COMBIMATRIX CORPORATION, WE MAY BE SUBJECT TO CERTAIN TAX LIABILITY UNDER THE INTERNAL REVENUE CODE.  
Our distribution of the common stock of CombiMatrix inCorporation, or CombiMatrix, upon completion of the transaction whereby we split-off CombiMatrix, a former component of our life science business, to become an independent publicly-held company, or the Split-Off Transaction, will be tax-free to us if the distribution qualifies under Sections 368 and 355 of the Internal Revenue Code of 1986, as amended, or the Code.  If the Split-Off Transaction fails to qualify under Section 355 of the Code, corporate tax would be payable by the consolidated group as of the date of the Split-Off Transaction, of which we are the common parent, based upon the difference between the aggregate fair market value of the assets of CombiMatrix’sCombiMatrix's business and the adjusted tax bases of such businessbus iness to us prior to the redemption.
 
We received a private letter ruling from the Internal Revenue Service, or the IRS, to the effect that, among other things, the redemption would be tax free to us and the holders of Acacia Research-Acacia Technologies common stock and Acacia Research-CombiMatrix common stock under Sections 368 and 355 of the Code. The private letter ruling, while generally binding upon the IRS, was based upon factual representations and assumptions and commitments on our behalf with respect to future operations made in the ruling request. The IRS could modify or revoke the private letter ruling retroactively if the factual representations and assumptions in the request were materially incomplete or untrue, the facts uponu pon which the private letter ruling was based were materially different from the facts at the time of the redemption, or if we do not comply with certain commitments made.

If the Split-Off Transaction fails to qualify under Section 355 of the Code, corporate tax, if any, would be payable by the consolidated group of which we are the common parent, as described above.  As such, the corporate level tax would be payable by us. CombiMatrix has agreed however, to indemnify us for this and certain other tax liabilities if they result from actions taken by CombiMatrix.  Notwithstanding CombiMatrix’sCombiMatrix's agreement to indemnify us, under the Code’sCode's consolidated return regulations, each member of our consolidated group, including our company, will be severally liable for these tax liabilities. Further, we may be liable for additional taxes if we take certain actions within two years following the redemption, as more fully discussed in the immediately following risk factor.  If we are found liable to the IRS for these liabilities, the resulting obligation could materially and adversely affect our financial condition, and we may be unable to recover on the indemnityindem nity from CombiMatrix.
 
FOLLOWING THE REDEMPTION OF ACACIA RESEARCH-COMBIMATRIX COMMON STOCK FOR THE COMMON STOCK OF COMBIMATRIX, WE MAY BE SUBJECT TO CERTAIN TAX LIABILITIES UNDER THE INTERNAL REVENUE CODE FOR ACTIONS TAKEN BY US OR COMBIMATRIX FOLLOWING THE REDEMPTION.Following the redemption of Acacia Research-CombiMatrix common stock for the common stock of CombiMatrix, we may be subject to certain tax liabilities under the Internal Revenue Code for actions taken by us or CombiMatrix following the redemption.  
 
Even if the distribution of the common stock of CombiMatrix upon completion of the Split-Off Transaction qualifies under Section 368 and 355 of the Code, itsuch distribution will be taxable to us if Section 355(e) of the Code applies to the distribution. Section 355(e) will apply to the distribution if 50% or more of our common stock or CombiMatrix’sof CombiMatrix's common stock, by vote or value, is acquired by one or more persons, other than the holders of Acacia Research-CombiMatrix common stock who receivereceived the common stock of CombiMatrix in the redemption, acting pursuant to a plan or a series of related transactions that includes the redemption. Any shares of our common stock, of the Acacia Research-CombiMatrix common stock or of the common stock of CombiMatrix acquired directly or indirectly within two years before or after the redemption generally are presumed to be part of such a plan unless we can rebut that presumption. To prevent applicability of Section 355(e) or to otherwise prevent the distribution from failing to qualify under Section 355 of the Code, CombiMatrixC ombiMatrix has agreed that, until two years after the redemption, it will not take any of the following actions unless, prior to taking such action, it has obtained, and provided to us, a written opinion of tax counsel or a ruling from the IRS to the effect that such action will not cause the redemption to be taxable to us, which we refer to in this report collectively as Disqualifying Actions:
 
    merge or consolidate with another corporation;corporati on;
  
●     
•    liquidate or partially liquidate;
  
●     
•    sell or transfer all or substantially all of its assets;
  
●     
•    redeem or repurchase its stock (except in certain limited circumstances); or
  
●     
•    take any other action which could reasonably be expected to cause Section 355(e) to apply to the distribution.
13

 
Further, if we take any Disqualifying Action, we may be subject to additionaladdit ional tax liability.  Many of our competitors are not subject to similar restrictions and may issue their stock to complete acquisitions, expand their product offerings and speed the development of new technology.  Therefore, these competitors may have a competitive advantage over us.  Substantial uncertainty exists on the scope of Section 355(e), and we may have undertaken, may contemplate undertaking or may otherwise undertake in the future transactions which may cause Section 355(e) to apply to the redemption notwithstanding our desire or intent to avoid application of Section 355(e). Accordingly, we cannot provide you any assurance that we will not be liable for taxes if Section 355(e) applies to the redemption.
 
WE MAY FAIL TO MEET MARKET EXPECTATIONS BECAUSE OF FLUCTUATIONS IN QUARTERLY OPERATING RESULTS, WHICH COULD CAUSE THE PRICE OF OUR COMMON STOCK TO DECLINE.We may fail to meet market expectations because of fluctuations in quarterly operating results, which could cause the price of our common stock to decline.
 
Our reported revenues and operating results have fluctuated in the past and may continue to fluctuate significantly from quarter to quarter in the future. It is possible that in future periods, revenues could fall below the expectations of securities analysts or investors, which could cause the market price of our common stock to decline. The following are among the factors that could cause our operating results to fluctuate significantly from period to period:
 
●     
•    the dollar amount of agreements executed in each period, which is primarily driven by the nature and characteristics of the technology being licensed and the magnitude of infringement associated with a specific licensee;
  
●     
•    the specific terms and conditions of agreements executed in each period and the periods of infringement contemplated by the respective payments;

15

 

●     
•    fluctuations in the total number of agreements executed;
  
●     
•    fluctuations in the sales results or other royalty-per-unit activities of our licensees that impact the calculation of license fees due;
  
●     
•    the timing of the receipt of periodic license fee payments and/or reports from licensees;
  
●     
•    fluctuations in the net number of active licensees period to period;
  
●     
•    costs related to acquisitions, alliances, licenses and other efforts to expand our operations;
 
●     
•    
the timing of payments under the terms of any customer or license agreements into which our operating subsidiaries may enter; and
  
●     
•    expenses related to, and the timing and results of, patent filings and other enforcement proceedings relating to intellectual property rights, as more fully described in this section.
  
TECHNOLOGY COMPANY STOCK PRICES ARE ESPECIALLY VOLATILE, AND THIS VOLATILITY MAY DEPRESS THE PRICE OF OUR COMMON STOCK.Technology company stock prices are especially volatile, and this volatility may depress the price of our common stock.
 
The stock market has experienced significant price and volume fluctuations, and the market prices of technology companies have been highly volatile. We believe that various factors may cause the market price of our common stock to fluctuate, perhaps substantially, including, among others, the following:
 
●     
•    announcements of developments in our patent enforcement actions;
  
●     
•    developments or disputes concerning our patents;
  
●     
•    our or our competitors’competitors' technological innovations;
  
●     
•    developments in relationships with licensees;
  
14

●     
•    variations in our quarterly operating results;
  
●     
•    our failure to meet or exceed securities analysts’analysts' expectations of our financial results;
  
●     
•    a change in financial estimates or securities analysts’analysts' recommendations;
  
●     
•     changes in management’smanagement's or securities analysts’analysts' estimates of our financial performance;
  
●     
•    changes in market valuations of similar companies;
 
●     
•    announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, capital commitments, new technologies, or patents; and
  
●     
•    failure to complete significant transactions.
  
For example, the NASDAQ ComputerNASDAQ-100 Technology Sector Index had a range of $582.76$1,028.30 - $1,288.12$1,400.84 during the 52-weeks ended December 31, 20082010 and the NASDAQ Composite Index had a range of $1,295.48$2,061.14 - $2,661.50$2,675.26 over the same period.  Over the same period, our common stock fluctuated within a range of $1.87$7.79 - $9.30.$ 30.20.
 
The financial crisis affecting the banking system and financial markets and the current uncertainty in global economic conditions, which began in late 2007 and continued throughout 2008,2009 and into 2010, have resulted in a tightening in the credit markets, a low level of liquidity in many financial markets, and extreme volatility in the credit, equity and fixed income markets. As noted above, our stock price, like many other stocks,others, has decreased substantiallyfluctuated significantly recently and if investors have concerns that our business, operating results and financial condition will be negatively impacted by a continuing worldwide economic downturn, our stock price could further decrease.continue to fluctuate significantly in future periods.
 

16


In addition, we believe that fluctuations in our stock price during applicable periodsper iods can also be impacted by court rulings and and/or other developments in our patent licensing and enforcement actions. Court rulings in patent enforcement actions are often difficult to understand, even when favorable or neutral to the value of our patents and our overall business, and we believe that investors in the market may overreact, causing fluctuations in our stock prices that may not accurately reflect the impact of court rulings on our business operations and assets.
 
In the past, companies that have experienced volatility in the market price of their stock have been the objects of securities class action litigation. If our common stock was the object of securities class action litigation, it could result in substantial costs and a diversiond iversion of management’smanagement's attention and resources, which could materially harm our business and financial results.
 
We do not anticipate declaring any cash dividends on our common stock.
We have never declared or paid cash dividends on our common stock and do not plan to pay any cash dividends in the near future. Our current policy is to retain all funds and any earnings for use in the operation and expansion of our business. If we do not pay dividends, our stock may be less valuable to you because a return on your investment will only occur if our stock price appreciates.

ItemITEM 3. LEGAL PROCEEDINGS

In the ordinary course of business, we are the subject of, or party to, various pending or threatened legal actions, including various counterclaims in connection with our intellectual property enforcement activities.  We believe that any liability arising from these actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows.

In connection with any of our patent enforcement actions, it is possible that a defendant may request and/or a court may rule that we have violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions.  In such event, a court may issue monetary sanctions against us or our operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material, and if required to be paid by us or our operating subsidiaries, could materially harm our operating results and our financial position.

Price Range of Common Stock
 
Prior to the Split-Off Transaction described above, we had two classes of common stock outstanding, our Acacia Research-Acacia Technologies common stock and our Acacia Research-CombiMatrix common stock.  Our Acacia Research-Acacia Technologies common stock was intended to reflect separately the performance of our intellectual property licensing business.  Our Acacia Research-CombiMatrix common stock was intended to reflect separately the performance of our life science business, referred to as the CombiMatrix group, which was disposed of in connection with the Split-Off Transaction.
As a result of the Split-Off Transaction, all outstanding shares of Acacia Research-CombiMatrix common stock were redeemed, and all rights of holders of Acacia Research-CombiMatrix common stock ceased as of August 15, 2007, except for the right, upon the surrender to the exchange agent of shares of Acacia Research-CombiMatrix common stock, to receive new shares of CombiMatrix common stock.  As a result of the consummation of the Split-Off Transaction, our only class of common stock outstanding is our common stock.
Our common stock commenced tradingtrades on The NASDAQ Global Select Market on December 16, 2002, under the symbol “ACTG.”  Prior to December 16, 2002, our onlyo nly class of common stock began trading under the symbol “ACRI”traded on the NASDAQ National Market System on July 8, 1996.
The markets for securities such as our common stock have historically experienced significant price and volume fluctuations during certain periods. These broad market fluctuations and other factors, such as new product developments and trends in our industry andunder the investment markets generally, as well as economic conditions and quarterly variations in the results of our enforcement activities and our results of operations, may adversely affect the market price of our common stock.symbol “ACRI.”

(1)Discontinued operations reflects the impact of the Split-Off Transaction described below.
 
Factors Affecting Comparability:
 
•    
The increase in revenues in fiscal year 2010, as compared to fiscal year 2009, was due primarily to an increase in the average revenue per executed agreement and an increase in the number of new licensing agreements executed during the period.In fiscal 2010, we entered into a number of separate significant revenue agreements with unrelated third parties resolving pending patent matters.
•    Net income attributable to noncontrolling interests in operating subsidiaries, or net income attributable to noncontrolling interests, represents the portion of net income or loss from the licensing and enforcement activities of our majority-owned operating subsidiaries that are distributable to the operating subsidiary's noncontrolling interest holders pursuant to the underlying operating agreements.
•    
Inventor royalties, net income attributable to noncontrolling interests, and contingent legal fees, on a combined basis, increased 30% in fiscal year 2010, as compared to fiscal year 2009, primarily reflecting the increase in related revenues for the same periods. The increase was less than the percentage increase in related revenues for the same periods, due to, in the aggregate, lower or no inventor royalty or contingent legal fee arrangement obligations associated with the portfolios generating revenues in fiscal year 2010, as compared to fiscal year 2009.
•   &nb sp;
The increase in the our tax expense in fiscal year 2010, as compared to fiscal year 2009, reflects the impact of the suspension of the use of NOLs in California, as described below, and the calculation of tax expense for financial reporting purposes without the excess tax benefit related to the exercise and vesting of equity-based incentive awards in fiscal year 2010. Accordingly, the excess tax benefit related to the exercise and vesting of equity-based incentive awards in fiscal year 2010 was credited to additional paid-in capital, not tax expense. The actual tax benefit realized for excess tax deductions resulting from the exercise and vesting of equity-based incentive awards in fiscal year 2010 totaled $1.3 million. As a result of the excess tax benefit realized, our state taxes payable in fiscal year 2010, for the 2010 tax year, totaled $170,000, primarily relating to California state minimum taxes for the 2010 tax year.

The intellectual property acquisition, development, licensing and enforcement business conducted by our operating subsidiaries, is described more fully ini n Item 1, “Business,” of this report.

CombiMatrix Group Split-Off Transaction and Related Discontinued Operations. As discussed below under the caption “Discontinued Operations – Split-Off of CombiMatrix Corporation,” the CombiMatrix group, which was previously presented as a separate reportable segment, was split-off from us effective August 15, 2007.  As such, the historical results of operations for the CombiMatrix group in the accompanying consolidated financial statements are presented as part of our results from discontinued operations in accordance with SFAS No. 144.  As a result of the Split-Off Transaction, our only business is our intellectual property licensing business.
Overview

Our operating activities during 2008, 2007 and 2006,for the periods presented were principally focused on the continued development, licensing and enforcement of the patent portfolios owned or controlled by our operating subsidiaries, including the continued pursuit of multipleour ongoing technology licensing and enforcement programs and the development and commencement of new technology licensing and enforcement programs.  In addition, we continued our focus on business development, including the acquisition of several additional patent portfolios by certain of our operating subsidiaries and the continued pursuit of additional opportunities to partner with patent owners and providecontinue our unique intellectual property licensing, development and enforcement services.

We recognized license fee revenues of $48.2 million in 2008, an 8% decrease compared to 2007 license fee revenues of $52.6 million, and a 38% increase compared to 2006 license fee revenues of $34.8 million.

Overview - Fiscal year 2010 compared with Fiscal Year 2009
•    
Revenues increased $64.5 million, or 96%, due primarily to an increase in the average revenue per executed agreement and an increase in the number of new licensing agreements executed during the period.
•    Cost of Revenues and Other Operating Expenses:
◦    
Inventor royalties, net income attributable to noncontrolling interests, and contingent legal fees, on a combined basis, increased 30%, primarily reflecting the increase in related revenues for 2010. The increase was less than the percentage increase in related revenues due to, in the aggregate, lower or no inventor royalty or contingent legal fee arrangement obligations associated with the portfolios generating revenues in fiscal year 2010, as compared to fiscal year 2009.
◦    
Litigation and licensing expenses-patents decreased to $13.9 million, as compared to $14.1 million in the prior year, due to a lower net level of litigation support, third party technical consulting and professional expert expenses incurred in fiscal year 2010. The decrease was partially offset by an increase in litigation and licensing expenses incurred in connection with our continued investment in ongoing licensing and enf orcement programs and new licensing and enforcement programs commenced since the end of the prior year period.
◦    
Marketing, general and administrative expenses increased to $25.1 million, as compared to $21.1 million in the prior year, due primarily to an increase in variable performance-based compensation costs, an increase in other variable personnel costs, and a minor net increase in engineering and licensing personnel, non-cash stock compensation charges and state related gross receipts taxes incurred on certain licensing revenues recognized in fiscal year 2010.
◦    Patent amortization increased $2.3 million, or 50%, due primarily to the acceleration of patent amortization related to recoupable up-front patent portfolio acquisition costs that were recovered in fiscal year 2010 and an increase in amortization related to new patent portfolios acquired in fiscal year 2010.
Overview - Fiscal Year 2009 compared with Fiscal Year 2008
•    
Revenues increased $19.1 million, or 40%, due primarily to an increase in the number of new licensing agreements executed during the period, which was partially offset by a minor decrease in the average revenue per license agreement executed during the same period.
•    Cost of Revenues and Other Operating Expenses:
◦    Inventor royalties, net income attributable to noncontrolling interests, and contingent legal fees, on a combined basis, increased 36%, primarily reflecting the increase in related revenues for the same periods.
◦    
Litigation and licensing expenses-patents increased to $14.1 million, as compared to $6.9 million in the prior year, due to an increase in litigation and licensing support related out of pocket expenses, third party technical consulting expenses, professional expert expenses and other litigation support and administrative costs incurred in connection with our investment in certain of our licensing and enforcement programs that went to trial and concluded in fiscal year 2009, licensing and enforcement programs with trial dates scheduled for fiscal year 2010, and a net increase in costs related to new licensing and enforcement programs commenced since the end of the prior year period.

26


◦    
Marketing, general and administrative expenses remained relatively flat in fiscal year 2009, as compared to fiscal year 2008.
◦    Patent amortization decreased $1.4 million, or 23%, due primarily to higher amortization expense recorded in fiscal year 2008 resulting from the acceleration of amortization on a patent portfolio, and a scheduled decrease in amortization, which was partially offset by an increase in amortization expense rel ated to new patent portfolios acquired in fiscal year 2009.
Patent Licensing and Enforcement
We expect patent-related legal expenses to continue to fluctuate from period to period based on the aggregate, total inventor royaltiesfactors summarized below, in connection with future trial dates and contingent legal fees expenses decreasedour current and future patent acquisition, development, licensing and enforcement activities. The pursuit of enforcement actions in 2008, as compared to 2007,connection with our licensing and increasedenforcement programs can involve certain risks and uncertainti es, including the following:
•    Increases in patent-related legal expenses, including, but not limited to, increases in costs billed by outside legal counsel for discovery, depositions, economic analyses, damages assessments, expert witnesses and other consultants, case-related audio/video presentations and other litigation support and administrative costs could increase our operating costs and decrea se our revenue generating opportunities;
•    Our patented technologies and enforcement actions are complex, and as a result, we may be required to appeal adverse decisions by trial courts in order to successfully enforce our patents;
•    New legislation, regulations or rules related to enforcement actions could significantly increase our operating costs and decrease our revenue generating opportunities; and
•    Courts may rule that our subsidiaries have violated certain statutory, regulatory, federal, local or governing rules or standards by pursuing such enforcement actions, which may expose us and our operating subsidiaries to material liabilities, which could harm our operating results and our financial position.
Investments in 2007, as compared to 2006, primarily due to the related fluctuations in license fee revenues for the same periods, as discussed above, and the impact of the varying economic terms related to inventor agreements and contingent legal fee arrangements associated with the revenue generating patent portfolios in each period.Patent Portfolios

Our operating subsidiaries intend to sustain the long term growth of our intellectual property licensing and enforcement business through the identification and acquisition of, or the rights to, additional core patented technologies, across a wide range of technology areas that have been,, or are anticipated to be,, widely adopted by third parties in connection with the manufacture or sale of products and services.  During
In fiscal years 2010, 2009 and 2008, certain of our operating subsidiaries continuedc ontinued to execute ourtheir business strategy in the area of patent portfolio acquisitions, including, in the fourth quarter of 2008, the acquisition of, or the acquisition of the rights to, patent portfolios in the Automated Tax Reporting, Improved Lighting, Vehicle Occupant Sensing and Wireless Data technology areas.  During 2008,acquisitions.  In fiscal year 2010, we acquired a total of 2036 new patent portfolios with applications over a wide range of technology areas, as compared to 3130 new patent portfolios, in 2007 and 20 new patent portfolios in 2006.  Referfiscal years 2009 and 2008, respectively. Patent portfolio acquisition costs in fiscal year 2010 totaled $8.2 million, as compared to “Liquidity$9.6 million and Capital Resources” below for information regarding$2.1 million in fiscal years 2009 and 2008, respectively.
In addition to trailing twelve-month revenues as discussed above, we also measure and assess the impactperformance and growth of the patent licensing and enforcement business conducted by our operating subsidiaries based on the number of patent and patent rights acquisitionsportfolios owned or controlled by our operating subsidiaries on oura consolidated financial statements for the periods presented.

basis.  As of December 31, 2010, 2009 and 2008 we had several option agreements, on a consolidated basis, our operating subsidiaries owned or controlled the rights to approximately 171, 138, and 108 patent portfolios, respectively, which include U.S. patents and certain foreign counterparts covering technologies used in a wide variety of industries.
Several of the patent portfolios acquired in fiscal years 2010 and 2009 were acquired in connection with third-party patent portfolio owners regarding the potential acquisitionpartnering arrangements executed with major technology companies, reflecting our continued identification of additionalopportunities to partner not only with individual inventors and small to medium size technology companies, but also major well established technology companies with larger patent portfolios.


Critical Accounting Policies

Our consolidated financial statements are prepared in conformityRenesas Electronics Corporation. In Augus t 2010, we entered into a strategic patent licensing alliance with accounting principles generally accepted in the United StatesRenesas Electronics Corporation, a premier supplier of America.  In preparing these financial statements, we make assumptions, judgmentsadvanced semiconductor solutions. Pursuant to this relationship, those patents selected by us and estimates that can have a significant impact on amounts reported in our consolidated financial statements. We base our assumptions, judgmentsRenesas Electronics from Renesas Electronics’ portfolio of over 40,000 patents and estimates on historical experience and various other factors that we believepatent applications will be assigned to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis, we evaluate our assumptions, judgments and estimates and make changes accordingly.us for patent licensing.

In general, the majority of acquisition costs incurred during the periods presented are subject to contractual provisions providing for higher percentage returns to our operating subsidiaries early in the licensing and enforcement program until such initial upfront acquisition costs are fully recovered. Of the $9.6 million in patent acquisition costs invested in fiscal year 2009, we have a contractual guarantee to receive a minimum of $5.0 million in net proceeds, which significantly reduces the risk associated with these initial investments.  
 
We believe that,The higher lev el of acquisition costs incurred in fiscal years 2010 and 2009 reflects our continued identification of opportunities to partner with individual inventors, small technology companies, research laboratories, universities, and major technology companies and exchange up front, advanced royalty payments to patent owners, for a reduced future inventor royalty percentage, resulting in the significant accounting policies discussedpotential for higher returns on our investments in Note 2connection with future licensing and enforcement activities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



Board of Directors and Stockholders
Acacia Research Corporation
 
We have audited Acacia Research Corporation’s (a Delaware corporation) internal control over financial reporting as of December 31, 2008,2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Acacia Research Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on Acacia Research Corporation’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances.cir cumstances. We believe that our audit provides a reasonable basis for our opinion.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statementsstatement s in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policiespoli cies or procedures may deteriorate.
 
In our opinion, Acacia Research Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008,2010, based on criteria established in Internal Control—Integrated Framework issued by COSO.
 
We also haveh ave audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Acacia Research Corporation as of December 31, 20082010 and 2007,2009, and the related consolidated statements of operations, and comprehensive loss, stockholders’ equity, and cash flows for each of the twothree years in the period ended December 31, 20082010 and our report dated February 26, 2009,28, 2011 expressed an unqualified opinion.opinion and contained an explanatory paragraph relating to the change in accounting method for term agreements in 2009.

Change in Accounting Policy for Term Agreements. Certain revenue agreements provide for the payment of marketable securities;

We discuss below the critical accounting assumptions, judgments and estimates associated with these policies. Historically, our assumptions, judgments and estimates relative to our critical accounting policies have not differed materially from actual results. For further information on our critical accounting policies, refer to Note 2 to the consolidated financial statements included herein.

Revenue Recognition
As described below, significant management judgments must be made and used in connection with the revenue recognized in any accounting period.  Material differences may result in the amount and timing of revenue recognized or deferred for any period, if management made different judgments.

Revenue is recognized, in accordance with Staff Accounting Bulletin No. 104, “Revenue Recognition,” or SAB No. 104, when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pursuant to the terms of the agreement, (iii) amounts are fixed or determinable and (iv) collectibility of amounts is reasonably assured.

We make estimates and judgments when determining whether the collectibility of license fees receivable from licensees is reasonably assured. We assess the collectibility of license fees receivable based on a number of factors, including past transaction history and the credit-worthiness of licensees.  If it is determined that collection is not reasonably assured, the fee is recognized when collectibility becomes reasonably assured, assuming all other revenue recognition criteria have been met, which is generally upon receipt of cash. Management estimates regarding collectibility impact the actual revenues recognized each period and the timing of the recognition of revenues.  Our assumptions and judgments regarding future collectibility could differ from actual events, thus materially impacting our financial position and results of operations.

Certain license agreements provide for the payment of contractually determined paid-up license fees to our operating subsidiaries in consideration for the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by our operating subsidiaries.  Generally, the execution of these license agreements also provide for the release of the licensee from certain past and future claims, and the dismissal of any pending litigation.  Pursuant to the terms of these agreements, our operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future license and related releases, including no express or implied obligation on our operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the license and releases upon execution of the agreement.  As such, the earnings process is generally complete upon the execution of the agreement, and revenue is recognized upon execution of the agreement, when collectibility is reasonably assured, and all other revenue recognition criteria have been met.  Depending on the complexity of the underlying license agreement and related terms and conditions, significant judgments, assumptions and estimates may be required to determine when substantial delivery of contract elements has occurred, whether any significant ongoing obligations exist subsequent to contract execution, whether amounts due are collectible and the appropriate period or periods, in which, or during which, respectively, the completion of the earning process occurs.  Depending on the magnitude of specific license agreements, if different judgments, assumptions and estimates are made regarding contracts executed in any specific period, our financial results may be materially affected.
Our operating subsidiaries are responsible for the licensing and enforcement of their respective patented technologies and pursue third parties that are utilizing their intellectual property without a license or who have under-reported the amount of royalties owed under a license agreement.  As a result of these activities, from time to time, our operating subsidiaries may recognize royalty revenues in a current period that relate to infringements by licensees that occurred in prior periods.  These royalty recoveries may cause revenues to be higher than expected during a particular reporting period and may not occur in subsequent periods.  Differences between amounts initially recognized and amounts subsequently audited or reported as an adjustment to those amounts, are recognized in the period such adjustment is determined as a change in accounting estimate.

Stock-based Compensation Expense

Effective January 1, 2006, we adopted the provisions of SFAS No. 123R, which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation.”  SFAS No. 123R supersedes Accounting Principles Board, or APB, Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS No. 95, “Statement of Cash Flows.”  SFAS No. 123R sets forth the accounting requirements for “share-based” compensation payments to employees and non-employee directors and requires all share based-payments to be recognized as expense in the statement of operations. The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award (determined using a Black-Scholes option pricing model for stock options and intrinsic value on the date of grant for nonvested restricted stock), and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).  Determining the fair value of stock-based awards at the grant date requires significant estimates and judgments, including estimating the market price volatility of our common stock, future employee stock option exercise behavior and requisite service periods.
SFAS No. 123R also requires stock-based compensation expense to be recorded only for those awards expected to vest using an estimated pre-vesting forfeiture rate.  As such, SFAS No. 123R requires us to estimate pre-vesting option forfeitures at the time of grant and reflect the impact of estimated pre-vesting option forfeitures on compensation expense recognized.  Estimates of pre-vesting forfeitures must be periodically revised in subsequent periods if actual forfeitures differ from those estimates.  We consider several factors in connection with our estimate of pre-vesting forfeitures including types of awards, employee class, and historical pre-vesting forfeiture data.  The estimation of stock awards that will ultimately vest requires judgment, and to the extent that actual results differ from our estimates, such amounts will be recorded as cumulative adjustments in the period the estimates are revised.  If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted.
Refer to Notes 2 and 11 to our consolidated financial statements included in Part IV, Item 15 of this report for more information.
Valuation of Long-lived and Intangible Assets

We review long-lived assets, including patent related intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  Factors we consider important, which could trigger an impairment review include the following:a minimum upfront fee at the inception of each contractual term in consideration for the respective intellectual property rights granted, hereinafter referred to as “term agreements.”  Effective October 1, 2009, we elected to change our method of accounting for our term agreements to recognize reve nue when delivery of the intellectual property rights and all other arrangement deliverables has substantially occurred, which is typically at the time of execution of the related term agreement, or upon receipt of the applicable minimum upfront renewal payment, and when all other revenue recognition criteria, as described below, have been met.   Prior to the change in method of accounting, fees for term agreements were deferred and amortized to revenue on a straight-line basis over the applicable contractual term. We adopted the new method because it provides a consistent approach to accounting for all of our revenue arrangements with similar significant terms and conditions and more closely reflects the culmination of the earnings process associated with these revenue arrangements.  
 
We accounted for the change in accounting policy through a retrospective application of the new accounting policy as of January 1, 2009.  The effect of applying the new accounting policy to term agreements in periods prior to January 1, 2009 was not material.  Accordingly, our consolidated financial statements for years ending prior to January 1, 2009 have not been retroactively adjusted for this change in accounting policy.
●   30
significant underperformance relative to expected historical or projected future operating results;

 

As described below, significant management judgments must be made and used in connection with the revenue recognized in any accounting period.  Material differences may result in the amount and timing of revenue recognized or deferred for any period, if management made different judgments.
Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been performed pur suant to the terms of the agreement, (iii) amounts are fixed or determinable and (iv) collectibility of amounts is reasonably assured.
We make estimates and judgments when determining whether the collectibility of fees receivable from licensees is reasonably assured. We assess the collectibility of fees receivable based on a number of factors, including past transaction history and the credit-worthiness of licensees.  If it is determined that collection is not reasonably assured, the fee is recognized when collectibility becomes reasonably assured, assuming all other revenue recognition criteria have been met, which is generally upon receipt of cash for transactions where collectibility may have been an issue. Management's estimates regarding collectibility impa ct the actual revenues recognized each period and the timing of the recognition of revenues.  Our assumptions and judgments regarding future collectibility could differ from actual events and thus materially impact our financial position and results of operations.
In general, our revenue arrangements provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by our operating subsidiaries.  These rights typically include some combination of the following:  (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by our operating subsid iaries, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and (iv) the dismissal of any pending litigation.  The intellectual property rights granted may be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment.  Pursuant to the terms of these agreements, our operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on our operating subsidiaries' part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverab les upon execution of the agreement, or upon receipt of the minimum upfront payment for term agreement renewals.  As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, when collectibility is reasonably assured, or upon receipt of the minimum upfront fee for term agreement renewals, and when all other revenue recognition criteria have been met.
Depending on the complexity of the underlying revenue arrangement and related terms and conditions, significant judgments, assumptions and estimates may be required to determine when substantial delivery of contract elements has occurred, whether any significant ongoing obligations exist subsequent to contract execution, whether amounts due are collectible and the appropriate period or periods in which, or during which, the completion of the earning process occurs.  Depending on the magnitude of specific revenue arrangements, if different judgments, assumptions and estimates are made regarding contracts executed in any specific period, our periodic financial results may be materially affected.
Our operating subsidiaries are responsible for the licensing and enforcement of their respective patented technologies and pursue third parties that are utilizing their intellectual property without a license or who have under-reported the amount of royalties owed under a license agreement.  As a result of these activities, from time to time, our operating subsidia ries may recognize revenues in a current period that relate to infringements by licensees that occurred in prior periods.  These recoveries may cause revenues to be higher than expected during a particular reporting period and may not occur in subsequent periods.  Differences between amounts initially recognized and amounts subsequently audited or reported as an adjustment to those amounts, are recognized in the period such adjustment is determined as a change in accounting estimate.
The economic terms of the inventor agreements, operating agreements and contingent legal fee arrangements associated with the patent portfolios owned or controlled by our operating subsidiaries, if any, including royalty rates, contingent f ee rates and other terms, vary across the patent portfolios owned or controlled by our operating subsidiaries.  Inventor royalties, noncontrolling interests and contingent legal fees expenses fluctuate period to period, based on the amount of revenues recognized each period, the terms and conditions of revenue agreements executed each period and the mix of specific patent portfolios with varying economic terms and obligations generating revenues each period. Inventor royalties, noncontrolling interests and contingent legal fees expenses will continue to fluctuate and may continue to vary significantly period to period, based primarily on these factors.

●   31


During the year ended December 31, 2010, we entered into significant agreements with unrelated third parties resolving pending patent matters that resulted in the grant of certain intellectual property rights and recognition of revenues, the majority of which were not subject to inventor royalty and contingent legal fee arrangements, as well as the grant of licenses from certain of our operating subsid iaries and recognition of revenues that were subject to inventor royalties and contingent legal fee arrangements.  Revenues recognized subject to inventor royalties and contingent legal fees are based on a determination by the respective operating subsidiaries. Depending on the magnitude of specific revenue arrangements, if different judgments are made regarding revenues subject to inventor royalties and contingent legal fees in any specific period, our periodic financial results may be materially affected.
Stock-based Compensation Expense
Stock-based compensation payments to employees and non-employee directors are recognized as expense in the statements of operations. The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award (determined using a Black-Scholes option pricing model for stock options and intrinsic value on the date of grant for nonvested restricted stock), and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).  Determining the fair value of stock-based awards at the grant date requires significant estimates and judgments, including estimating the market price volatility of our common stock, future employee stock option exercise behavior and requisite service periods.
Stock-based compensation expense is recorded only for those awards expected to vest using an estimated pre-vesting forfeiture rate.  As such, we are required to estimate pre-vesting option forfeitures at the time of grant and reflect the impact of estimated pre-vesting option forfeitures on compensation expense recognized.  Estimates of pre-vesting forfeitures must be periodically revised in subsequent periods if actual forfeitures differ from those estimates.  We consider several factors in connection with our estimate of pre-vesting forfeitures, including types of awards, employee class, and historical pre-vesting forfeiture data.  The estimation of stock awards that will ultimately vest requires judgment, and to the extent that actual results differ from our estimates, such amounts will be recorded as cumulative adjustments in the period the estimates are revised.  If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted. Refer to Notes 2 and 11 to our consolidated financial statements included elsewhere herein.
Valuation of Long-lived and Intangible Assets
We review long-lived assets, including patent-related intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  Factors we consider important, which could trigger an impairment review, include the following:
•    significant underperformance relative to expected historical or projected future operating results;
•    significant changes in the manner of our use of the acquired assets or the strategy for our overall business;
•    significant negative industry or economic trends;
•    significant adverse changes in legal factors or in the business climate, including adverse regulatory actions or assessments; and
•    significant decline in our stock price for a sustained period.
If a potential impairment exists, a calculation is performed to determine the fair value of the long-lived asset. This calculation is based on a valuation model, which considers the estimated future undiscounted cash flows resulting from the use of the acquiredasset, and a discount rate commensurate with the risks involved. Third party appraised values may also be used in determining whether impairment potentially exists. The estimated fair value is compared to the long-lived asset's' carrying value to determining whether impairment exists.
As described above, in assessing the recoverability of intangible assets, significant judgment is required in connection with estimates of market values, estimates of the amount and timing of future cash flows, and estimates of other factors that are used to determine the fair value of the respective assets. If these estimates or related projections change in future periods, future intangible asset impairment tests may result in charges to earnings.

We calculate estimated future undiscounted cash flows, before interest and taxes, resulting from the use of the asset and its estimated value at disposal and compare it to its carrying value in determining whether impairment potentially exists. If a potential impairment exists, a calculation is performed to determine the fair value of the long-lived asset. This calculation is based on a valuation model and discount rate commensurate with the risks involved. Third party appraised values may also be used in determining whether impairment potentially exists.

As described above, in assessing the recoverability of intangible assets, significant judgment is required in connection with estimates of market values, estimates of the amount and timing of future cash flows, and estimates of other factors that are used to determine the fair value of the respective assets. If these estimates or related projections change in future periods, future intangible asset impairment tests may result in charges to earnings.  Refer to Note 6 to the consolidated financial statements, included elsewhere herein, for information on impairment charges recorded during the periods presented.

Impairment of Marketable Securities

Effective January 1, 2008, we adopted SFAS No. 157.  SFAS No. 157 establishes a common definition for fair value to be applied to U.S. generally accepted accounting principles guidance requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements.  SFAS No. 157 defines fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. SFAS No. 157 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. SFAS No. 157fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established a three-level hierarchy of valuation techniques used to measure fair value, is defined as follows:
 
●   
•    Level 1 - Observable Inputs:  Quoted prices in active markets for identical investments;
 
●   
•    Level 2 - Pricing Models with Significant Observable Inputs:  Other significant observable inputs, including quoted prices for similar investments, interest rates, credit risk, etc.; and
 
●   
•    Level 3 - Unobservable Inputs:  Significant unobservable inputs, including the entity’s own assumptions in determining the fair value of investments.
We use observable market inputs (quoted market prices) when measuring fair value and are required to use a Level 1 quoted price to measure fair value whenever possible.
At December 31, 2010 and 2009, our investments were comprised of auction rate securities classified as available-for-sale, which are reported at fair value, and included in Level 3 of the valuation hierarc hy described above.  The fair values of auction rate securities included in Level 3 of the hierarchy of valuation techniques are estimated utilizing an analysis of certain unobservable inputs and by reference to a discounted cash flow analysis.  These analyses consider, among other items, the underlying structure of each security, the collateral underlying the security investments, the creditworthiness of the counterparty, the present value of future principal and contractual interest payments discounted at rates considered to be reflective of current market conditions, consideration of the probabilities of default, continued auction failure, or repurchase or redemption at par for each period, and estimates of the time period over which liquidity related issues will be resolved. Observable market data for instruments with similar characteristics to our auction rate securities is also considered when possible.
Significant judgment is required in connection with the assumptions and inputs included in the discounted cash flow analysis and estimates of other factors that are used to determine the fair value of investments.
our marketable securities.  If these estimates and assumptions change in future periods, future estimates of the fair value of our marketable securities may result in additional charges to earnings.
We review impairments associated with our investments in marketable securities to determine the classification of any impairment as “temporary” or “other - -than-temporary.”   For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in the consolidated statements of operations.  An impairment is deemed other than temporary unless (a) we have the ability and intent to hold an investment for a period of time sufficient for recovery of its carrying amount and (b) positive evidence indicating that the investment's carrying amount is recoverable within a reasonable period of time outweighs any evidence to the contrary. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, the carrying amount of the investment is recoverable within a reasonable period of time.
Refer to “Consolidated Results of Operations – Other” below for information regarding other-than-temporary charges and related recoveries recorded in the consolidated statements of operations for the periods presented.

Two licensees individually accounted for 35% and 19%, respectively, of revenues recognized in fiscal year 2010, two licensees individually accounted for 15% and 12%, resp ectively, of revenues recognized in fiscal year 2009, and two licensees individually accounted for 13% and 12%, respectively, of revenues recognized in fiscal year 2008.
On a consolidated basis, as of December 31, 2010, 91 of our licensing programs had begun generating licensing revenues, up from 60 as of December 31, 2009 and 48 as of December 31, 2008.
Revenues recognized by our operating subsidiaries fluctuate from period to period primarily based on the following factors:
 
SFAS No. 157 requires the use of observable market inputs (quoted market prices) when measuring fair value and requires a Level 1 quoted price to be used to measure fair value whenever possible.
•    the dollar amount of agreements executed each period, which can be driven by the nature and characteristics of the technology or technologies being licensed and the magnitude of infringement associated with a specific licensee;
 
At December 31, 2008 and 2007, all of our investments are classified as available-for-sale, which are reported at fair value, in accordance with SFAS No. 157, with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders’ equity until realized.
We review impairments associated with our investments in marketable securities in accordance with Emerging Issues Task Force, or EITF, 03-1 and FSP SFAS 115-1 and 124-1, “The Meaning of Other-Than-Temporary-Impairment and Its Application to Certain Investments,” to determine the classification of any impairment as “temporary” or “other-than-temporary.”   For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in the consolidated statements of operations.  An impairment is deemed other than temporary unless (a) we have the ability and intent to hold an investment for a period of time sufficient for recovery of its carrying amount and (b) positive evidence indicating that the investment's carrying amount is recoverable within a reasonable period of time outweighs any evidence to the contrary. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, the carrying amount of the investment is recoverable within a reasonable period of time.

License fees $48,227  $52,597  $34,825 

License Fees. Revenues for 2008 included license fees from 80 new licensing agreements covering 30 of our technology licensing and enforcement programs, as compared to 91 new licensing agreements covering 16 of our technology licensing and enforcement programs in 2007, and 72 new licensing agreements covering 14 of our technology licensing and enforcement programs in 2006.  The increase in license fee revenues in 2008 and 2007, as compared to 2006, reflects the impact of the increase in patent portfolios owned or controlled by our operating subsidiaries since 2006, and the related increase in the number of patent licensing and enforcement programs developed, launched and generating revenues since 2006.  On a consolidated basis, as of December 31, 2008, 48 of our licensing programs had begun generating licensing revenues, up from 28 as of December 31, 2007 and 20 as of December 31, 2006.  License fee revenues recognized by our operating subsidiaries fluctuate from period to period primarily based on the following factors:

  ● the timing and results of patent filings and other enforcement proceedings relating to our intellectual property rights;
●   
the dollar amount of agreements executed each period, which is primarily driven by the nature and characteristics of the technology being licensed and the magnitude of infringement associated with a specific licensee;
●   
•    the specific terms and conditions of agreements executed each period, including the nature and characteristics of rights granted, and the periods of infringement or term of use contemplated by the respective payments;
•    fluctuations in the total number of agreements executed;
&bu ll;    fluctuations in the sales results or other royalty per unit activities of our licensees that impact the calculation of fees due;
•    the timing of the receipt of periodic payments and/or reports from licensees; and
•    fluctuations in the net number of active licensees from period to period.
The 96% increase in revenues in fiscal year 2010, as compared to fiscal year 2009, was due primarily to an increase in the average revenue per executed agreement and an increase in the number of new licensing agreements executed during the period. In fiscal year 2010, we entered into a number of separate significant revenue agreements with unrelated third parties resolving pending patent matters.
The 40 % increase in revenues for fiscal year 2009, as compared to fiscal year 2008, was due primarily to an increase in the number of new licensing agreements executed during the period, which was partially offset by a minor decrease in the average revenue per license agreement executed during the same periods.

(a)    The increase in inventor royalties and net income attributable to noncontrolling interests in fiscal year 2010, as compared to fiscal year 2009, was less than the increase in revenues for the same periods, pr imarily due to a portion of revenues recognized in fiscal year 2010 having no corresponding inventor royalty arrangement obligations, and in the aggregate, lower inventor royalty rates associated with the portfolios generating revenues in fiscal year 2010.
The increase in fiscal year 2009, as compared to fiscal year 2008 was due primarily to the increase in related revenues and a minor increase in inventor royalties and net income attributable to noncontrolling interests as a percentage of revenues.
(b)    The increase in contingent legal fees expense in fiscal year 2010, as compared fiscal year 2009, was less than the increase in revenues for the same periods, primarily due to a portion of revenues recognized in fiscal year 2010 having no corresponding contingent legal fee arrangement obligations, and in the aggregate, lower contingent legal fee rates associated with the portfolios generating revenues in fiscal year 2010.

The increase in fiscal year 2009, as compared to fiscal year 2008, was due to an increase in related revenues, partially offset by a decrease in contingent legal fees as a percentage of revenues due to certain patent portfolios with lower contingent fee rates generating revenues in fiscal year 2009.
Certain revenue agreements with unrelated third parties entered into in fiscal year 2010 resulted in the grant of certain intellectual property rights and recognition of revenues, the majority of which were not subject to inventor royalty and contingent legal fee arrangements, as well as the grant of licenses from certain of our operating subsidiaries and recognition of revenues that were subject to inventor royalties and contingent legal fee arrangements.  Revenues recognized subject to inventor royalties and contingent legal fees are based on a determination by the respective payments;

fluctuationsLitigation and Licensing Expenses - Patents.  Litigation and licensing expenses-patents include patent-related prosecution and enforcement costs incurred by outside patent attorneys engaged on an hourly basis and the out-of-pocket expenses incurred by law firms engaged on a contingent fee basis.  Litigation and licensing expenses-patents also include licensing and enforcement related third-party patent research, development, consulting, and other costs incurred in connection with the total numberlicensing and enforcement of agreements executed;
●   
fluctuations in the sales results or other royalty per unit activities of our licensees that impact the calculation of license fees due;
●   patent portfolios.  Litigation and licensing expenses-patents fluctuate from period to period based on patent enforcement and prosecution activity associated with ongoing licensing and enforcement programs and the timing of the receiptcommencement of periodicnew licensing and enforcement programs in each period. 
Litigation and licensing expenses-patents decreased slightly in fiscal year 2010, as compared to fiscal year 2009, reflecting relatively comparable net levels of related patent enforcement and prosecution activity associated with our continued investment in ongoing licensing and enforcement programs and new licensing and enforcement programs commenced since the end of the applicable prior year period.
Litigation and licensing expenses-patents increased 104% in fiscal year 2009, as compared to fiscal year 2008, due primarily to a n increase in litigation and licensing support related out of pocket expenses, third party technical consulting expenses, professional expert expenses and other litigation support and administrative costs incurred in connection with our continued investment in certain of our licensing and enforcement programs that went to trial and concluded in fiscal year 2009, licensing and enforcement programs with trial dates scheduled for fiscal year 2010, and a net increase in costs related to new licensing and enforcement programs commenced since the end of fiscal year 2008.
We expect patent-related legal expenses to continue to fluctuate period to period based on the factors summarized above, in connection with upcoming scheduled trial dates and our current and future patent acqui sition, development, licensing and enforcement activities.
Amortization of Patents.  Amortization expense increased 50% in fiscal year 2010, as compared to fiscal year 2009, due primarily to amortization on patent portfolios acquired since the end of the prior year period totaling $539,000, the acceleration of patent amortization related to recoupable up-front patent portfolio acquisition costs that were recovered in fiscal year 2010, pursuant to the provisions of the underlying inventor agreements totaling $ 1.2 million, and a scheduled increase in amortization related to intangible assets held as of the end of fiscal year 2009 totaling $312,000. In addition, fiscal year 2010 amortization expense included accelerated amortization totaling $275,000, related to a patent portfolio to which our operating subsidiary elected to terminate its rights, and a patent portfolio that was disposed of through a sale to an unrelated party.
Patent amortization expense decreased 23% in fiscal year 2009, as compared to fiscal year 2008, primarily due to higher amortization expense recorded in fiscal year 2008, resulting from the acceleration of amortization on a patent portfolio as described below, and a scheduled decrease in amortization totaling $950,000, whi ch was partially offset by an increase in amortization expense related to new patent portfolios acquired in fiscal year 2009 totaling $635,000.
In the fourth quarter of fiscal year 2008, pursuant to the terms of the respective inventor agreements, our management elected to terminate our rights to exclusively license fee payments and/or reports from licensees;a patent portfolio.  As such, the economic useful life of the patent-related intangible asset was reduced, resulting in the acceleration of $1.1 million of amortization expense for the patent-related asset in fiscal year 2008.

Non-cash stock compensation expense increased during 2008, as compared to 2007 and 2006, primarily due to an increase in the average fair value of equity-based incentive awards expensed during the periods presented.  The weighted-average grant date fair value of equity-based incentive awards expensed during 2008, 2007 and 2006, which is generally based on the grant date market value of our common stock, was approximately $11.66, $9.95 and $4.96, respectively.  The weighted-average grant date fair value of equity-based awards granted during 2008, 2007 and 2006 was $4.85, $12.74 and $6.88, respectively.  Equity-based awards are generally expensed on a straight-line basis over a two to three year vesting period.  Refer to Note 11 to our consolidated financial statements, included elsewhere herein, for additional information on equity-based award grant activity for the periods presented.   

Inventor Royalties and Contingent Legal Fees Expense.  Inventor royalties expense totaled $15.0 million, $12.1 million and $9.6 million in 2008, 2007 and 2006, respectively, and contingent legal fees expense totaled $12.4 million, $17.2 million and $7.5 million in 2008, 2007 and 2006, respectively.  Inventor royalties expenses and contingent legal fees expenses for the periods presented wereother costs incurred in connection with the recognition of the related license fee revenues, summarized above.  The majority of the patent portfolios owned or controlled by our operating subsidiaries are subject to patent and patent rights agreements with inventors containing provisions granting to the original patent owner the right to receive inventor royalties based on future net revenues, as defined in the respective agreements, and may also be subject to contingent legal fee arrangements with external law firms engaged on a contingent fee basis.  The economic terms of the inventor and contingent fee arrangements, if any, vary across our patent portfolios.  Certain contingent legal fee arrangements employ a graduated fee structure based on the stage of litigation.  As such, inventor royalties and contingent legal fee expensesbusiness development activities.  These costs fluctuate period to period based on the amount of revenues recognized each period and the mix of specific patent portfolios, with varying economic terms, generating revenues each period.

Certain patent portfolios generating revenues in 2008 had contingent legal arrangements with lower applicable contingent fee rates, as compared to those patent portfolios generating revenues in 2007, resulting in the 28% decrease in contingent legal fees expenses in 2008, versus 2007, as compared to the 8% decrease in license fee revenues during the same periods. Certain patent portfolios generating revenues in 2007 had inventor agreements with lower than average inventor royalty rates, as compared to those patent portfolios generating revenues in 2008, resulting in the 24% increase in inventor royalties expenses in 2008, versus 2007, as compared to the 8% decrease in license fee revenues during the same periods.  In addition, the lower contingent legal fee rates for certain patent portfolios generating revenue in 2008 also contributed to the period to period increase in inventor royalties expenses as a percentage of license fee revenues recognized.

Legal Expense – Patents. Patent-related legal expenses include patent-related prosecution and enforcement costs incurred by outside law firms engaged on an hourly basis and the out-of-pocket expenses incurred by outside law firms engaged on a contingent fee basis.  Patent-related legal expenses include casebusiness development related costs billed by outside counsel for discovery, depositions, economic analyses, damages assessments, expert witnesses and other consultants, case related audio/video presentations for the court, and other litigation support and administrative costs.  Patent-related legal expenses fluctuate from period to period based on patent enforcement and prosecution activity associated with ongoing licensing and enforcement programs and the timing of the commencement of new licensing and enforcement programsactivities in each period.

Provision for Income Taxes. The increase in the our tax expense in fiscal year 2010, as compared to fiscal year 2009, reflects the impact of the suspension of the use of NOLs in California, as described below, and the calculation of tax expense for financial reporting purposes without the excess tax benefit related to the exercise and vesting of equity-based incentive awards in fiscal year 2010.
Under U.S. generally accepted accounting principles, if a deduction reported on a tax return for an equity-based incentive award exceeds the cumulative compensation cost for those instruments recognized for financial reporting purposes, any resulting realized tax benefit that exceeds the previously calculated and recognized compensation expense for those instruments is considered an exce ss tax benefit, and is recognized as a credit to additional paid-in capital. The deduction related to the exercise and vesting of equity-based incentive awards in fiscal year 2010 is available to offset taxable income on our 2010 consolidated tax return, as no NOLs are allowed to be utilized for California tax return purposes in 2010, as described below. Accordingly, the excess tax benefit related to the exercise and vesting of equity-based incentive awards in fiscal year 2010 was credited to additional paid-in capital, not tax expense. The actual tax benefit realized for excess tax deductions resulting from the exercise and vesting of equity-based incentive awards in fiscal year 2010 totaled $1.3 million. As a result of the excess tax benefit realized, our state taxes payable in fiscal year 2010, for the 2010 tax year, totaled $170,000, primarily re lating to California state minimum taxes for the 2010 tax year.
 
In 2007, we incurred increased litigation support related outOctober 2010, the State of pocket expenses, third party technical consulting expenses and professional expert expenses incurred in connection with certain of our patent portfolios that were further along inCalifornia passed a state budget including provisions furthering the prosecutionsuspension of the related litigationuse of NOLs, for the 2010 and certain of our enforcement actions that proceeded2011 tax years. As a result, California State NOLs are not available to trial and concluded, resulting in increased patent –related legal expenses in 2007, as compared to 2008.  During 2008, none of our ongoing enforcement actions went to trial, despite an increase inoffset California taxable income for the overall number of outstanding enforcement actions during the period.2010 or 2011 tax years.

The increase in patent related legal expensesour effective tax rate in 2007,fiscal year 2009, as compared to 2006,  is primarily due tofiscal year 2008 reflects a net increasedecrease in ongoing patent enforcement litigationloss from continuing operations before provision for income taxes and an increase in litigation support related out of pocket expenses, third party technical consulting expensesstate minimum taxes and professional expert expenses incurredother state tax liabilities in connection withjurisdictions where certain of our patent portfolios that were further along in the prosecution of the related litigation and certain of our patent portfolios that proceeded to trial and concluded in 2007.

We expect patent-related legal expenses to continue to fluctuate period to period based on the factors summarized above, in connection with current and future patent licensing and enforcement programs.

Amortization of Patents.  During the fourth quarter of 2008, pursuant to the terms of the respective inventor agreement, management elected to terminate its rights to exclusively license a patent portfolio.  As such, the economic useful life of the patent related intangible asset was reduced, resulting in the acceleration of $1,094,000 of amortization expense for the patent related asset and an increase in amortization expense in 2008, as compared to 2007. This increase was partially offset by a reduction in scheduled amortization expense resulting from the completion of amortization on certain portfolios acquired in connection with the January 2005 GPH Acquisition.

The increase in 2007, as compared to 2006, was due to additional patent amortization charges related to certain patent portfolios acquired by ourAcacia's operating subsidiaries in late 2006 and throughout 2007.  Patent amortization charges will continue to be significant in future periods as we continue to amortize the acquired patent related costs over a weighted-average remaining economic useful life of approximately four years.  Refer to “Liquidity and Capital Resources” below for patent portfolio acquisition costs incurred during the periods presented.file separate state tax returns.

Discontinued Operations – Split-Off of CombiMatrix CorporationInflation
 
On August 15, 2007, or the Redemption Date, CombiMatrix was split-off from us through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock in exchange for the distribution of new shares of CombiMatrix, on a pro-rata basis, to the holders of Acacia Research-CombiMatrix stock as of the Redemption Date.  Subsequent to the Redemption Date, we no longer own any equity interests in CombiMatrix and the CombiMatrix group is no longer one of our business groups.

As a result of the Split-Off Transaction, the assets, liabilities, results of operations and cash flows of CombiMatrix have been eliminated from our continuing operations and we do not have any continuing involvement in the operations of CombiMatrix.  As a result of the Split-Off Transaction, we have disposed of our investment in CombiMatrix, and therefore, in accordance with guidance set forth in SFAS No. 144, our accompanying consolidated financial statements for all historical periods presented reflect the assets, liabilities, results of operations and cash flows for CombiMatrix as discontinued operations.  CombiMatrix was previously presented as a separate operating segment of us under SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.”
The Split-Off Transaction was accounted for by us at historical cost.  Accordingly, no gain or loss on disposal was recognized in the 2007 consolidated statement of operations. Included in the December 31, 2007 consolidated balance sheet is a charge to consolidated shareholders’ equity totaling $35,444,000, reflecting the distribution of our investment in the net assets of CombiMatrix to holders of Acacia Research-CombiMatrix stock, as of the Redemption Date.  We received a private letter ruling from the IRS with regard to the U.S. federal income tax consequences of the Split-Off Transaction to the effect that the Split-Off Transaction will be treated as a tax-free exchange under Sections 368 and 355 of the Code.
Refer to Note 10A to our consolidated financial statements included elsewhere herein for information regarding the revenues and pretax loss included in discontinued operations for the applicable historical periods presented.

Liquidity and Capital Resources

General
Our consolidatedprimary sources of liquidity are cash, cash equivalents and investments on hand generated from our opera ting activities. Our management believes that our cash and cash equivalents, investments, anticipated cash flow from operations, and other external sources of available credit, will be sufficient to meet our cash requirements through at least March 2012. We may, however, encounter unforeseen difficulties that may deplete our capital resources more rapidly than anticipated, including those set forth under Item 1A, “Risk Factors”, above. Any efforts to seek additional funding could be made through issuances of equity or debt, or other external financing. However, additional funding may not be available on favorable terms, if at all. The capital and credit markets have experienced extreme volatility and disruption since late 2007, and the volatility and impact of the disruption has continued into 2011. At times during this period, the volatility and disruption has reached unprecedented levels. In several cases, the markets have exerted downward pressure on stock prices and credit capacity for cert ain issuers, and there can be no assurance that the commercial paper markets will be a reliable source of short-term financing for us. If we fail to obtain additional funding when needed, we may not be able to execute our business plans and our business, conducted by our operating subsidiaries, may suffer.
As described above, in August 2010, one of our wholly-owned subsidiaries became the general partner of the Acacia IP Fund, which was formed in August 2010. The Acacia IP Fund is authorized to raise up to $250 million. The Acacia IP Fund acquires, licenses and enforces intellectual property consisting primarily of patents, patent rights, and patented technologies.
Cash, Cash Equivalents and Investments
Our consolidated cash, cash equivalents and investments on hand totaled $51.5$104.5 million at December 31, 2010, compared to $53.9 million at DecemberDece mber 31, 2008, compared to $51.4 million at December 31, 2007. Working capital at December 31, 2008 was $42.6 million, compared to $48.1 million at December 31, 2007.  The change in working capital primarily reflects the impact of cash flows used in continuing operating and investing activities, as discussed below.  In addition, the change in working capital also reflects the reclassification of $2.75 million (par value) of auction rate securities collateralized by student loans and $975,000 (par value) of auction rate securities issued by high credit quality closed-end investment companies to noncurrent assets as of December 31, 2008, as described above.

2009.  The net change in cash, and cash equivalents and investments on hand related to continuing operations for 2008, 20072010, 2009 and 20062008 was comprised of the following (in thousands):

Cash Flows from Investing Activities. The change in net cash flows used in investing activities was primarily due to the impact of patent portfolio acquisitions and net sales of available-for-sale investments in connection with ongoing short-term cash management activities during the periods presented.  Certain of our operating subsidiaries incurred patent acquisition costs totaling $8.2 million, $9.6 million and $2.1 million in fiscal years 2010, 2009 and 2008, respectively.  Net sales of short-term investments totaled $184,000, $1.0 million and $7.2 million in fiscal years 2010, 2009 and 2008, respectively.

Cash inflows from financing activities in fiscal years 2010, 2009 and 2008 included stock option exercise proceeds of $15.1 million, $247,000, and $142,000, respectively.
In May 2009, our board of directors approved a restricted stock vesting net issuance program.  Under the program, upon the vesting of unvested shares of restricted common stock, we withheld from fully vested shares of common stock otherwise deliverable to any employee-participant in our equity compensation programs, a number of whole shares of common stock having a fair market value (as determined by us as of the date of vesting) equal to the amount of tax required to be withheld by law, in order to satisfy the tax withholding obligations of ours in connection with the vesting of such shares.  Of a total of 580,600 shares of restricted stock vesting between June 2009 and September 2009, 174,628 shares of common stock were withheld by us, in satisfaction of $1.1 million in required withholding tax liability.
Working Capital
The primary components of working capital are cash and cash equivalents, accounts receivable, increasedprepaid expenses, accounts payable, accrued expenses, royalties and contingent legal fees payable and deferred revenues.  Working capital at December 31, 2010 was $92.3 million, compared to $7.4$36.0 million at December 31, 2008,2009.  
Consolidated accounts receivable from licensees increased to $8.0 million at December 31, 2010, compared to $1.4$5.1 million at December 31, 2007.  2009.  Accounts receivable balances fluctuate based on the timing, magnitude and payment terms associated with revenue agreements executed during the period, and the timing of cash receipts on accounts receivable balances recorded in previous periods. One licensee individually represented approximately 74% of accounts receivable at December 31, 2010. Two licensees individually represented approximately 78% and 10%, respectively, of accounts receivable at December 31, 2009.
Consolidated royalties and contingent legal fees payable increased to $10.8$12.8 million at December 31, 2010, compared to $12.4 million at December 31, 2008, compared to $2.3 million at December 31, 2007.  The increase in accounts receivable2009.  Royalties and contingent legal fees payable balances fluctuate based on the magnitude and timing of the execution of related license agreements, the timing of cash receipts for the related license agreements, and the timing of payment of current and prior period royalties and contingent legal fees payable primarily reflects higher license fee revenues recognized in the fourth quarter of 2008, as compared to the same period in 2007,inventor and the timing of cash receipts from licensees and the related payments to the inventors and contingent law firms with whom we partner.  outside attorneys, respectively.
The majority of accounts receivable from licensees at December 31, 20082010 were collected or scheduled to be collected in the first and second quarter of 2009,2011, in accordance with the terms of the related underlying license agreements.   The majority of royalties and contingent legal fees payable are scheduled to be paid in the first and second quarter of 2009,2011, upon receipt by us of the related license fee payments from licensees, in accordance withw ith the underlying contractual arrangements.

Investing Activities. The change in net cash flows used in investing activities for the periods presented reflects fluctuations in net purchasesAccounts payable and sales of available-for-sale investments in connection with ongoing cash management activities.  Short-term investments represent capital availableaccrued expenses decreased to fund current operations and fund capital expenditures.   In addition, certain of our operating subsidiaries incurred patent acquisition costs of $2.1$7.1 million $3.8 at December 31, 2010, from $8.0 million and $1.0 million in 2008, 2007 and 2006, respectively, relatedat December 31, 2009, due primarily to the acquisitiondecrease in litigation and licensing expenses-patents described above and the related timing of additional patent portfolios,payments to attorneys and other vendors.
Deferred revenues, representing non-refundable cash payments received from a licensee prior to all of the required revenue recognition criteria, as described earlier.

Financing Activities.  Consolidated net cash inflows from financing activities in 2008, 2007 and 2006 included stock option exercise proceeds of $142,000, $5.0 million, andabove, being met, totaled $1.5 million respectively.

Management believes that our consolidated cash and cash equivalent balances, anticipated cash flow fromat December 31, 2009.  These amounts were recognized as revenues in the statement of operations and other external sourcesi n the first quarter of available credit, will be sufficient to meet its cash requirements through at least Marchfiscal 2010, and for the foreseeable future.  However, we may, and our subsidiaries may, encounter unforeseen difficulties that may deplete our capital resources more rapidly than anticipated, including those set forth in Item 1A. “Risk Factors” included elsewhere herein.  There can be no assurance that funds from additional sources will be available when needed or, if available, will be on terms favorable to us or to our stockholders.  If additional funds are raised by issuing equity securities, the percentage ownership of our stockholders will be reduced, stockholders may experience additional dilution or such equity securities may provide for rights, preferences or privileges senior to those of the holders of our common stock.  If we and our subsidiaries fail to obtain additional funding when needed, they may not be able to execute their business plans and their businesses may suffer.

Item 7A.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal while concurrently maximizing the income we receive from our investments without significantly increasing risk. Some of the securities that we may invest in may be subject to interest rate market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the current value of the principal amount of our investment willmay decline. To minimize this risk, in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, high-grade corporate bonds, government and non-government debt securities and certificates of deposit. In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate. As of December 31, 2008,2010, all of our investments were in AAA rated money market funds that invest in U.S. Treasuryfirst-tier only securities, and obligationswhich primarily include domestic commercial paper, securities issued or guaranteed by the U.S. GovernmentU.S. government or its agencies, U.S. bank obligations, fully co llateralized repurchase agreements and certain auction rate securities.  A hypothetical 100 basis point increase in interest rates would not have a material impact on the fair value of our available-for-sale securities as of December 31, 2008.2010.  Refer to Item 1A.1A, “Risk Factors,” Item 7. “Liquidity7, --”Liquidity and Capital Resources,” and Notes 2 and 3 to our consolidated financial statements included in this report for additional information.  Refer to Note 7 to our consolidated financial statements included elsewhere herein for information on auction rate securities held as of December 31, 2008.for the periods presented.

1.  DESCRIPTION OF BUSINESSESBUSINESS

Description of Business. Acacia Research Corporation (“Acacia” or the “Company”) is comprised of Acacia and its wholly owned operating subsidiaries.  As used herein, “Acacia” and the “Company” refer to Acacia Research Corporation and/or its wholly ownedand majority-owned operating subsidiaries.  All intellectual property acquisition, development, licensing and enforcement activities are conducted solely by certain of Acacia’sAcacia's wholly ownedand majority-owned operating subsidiaries.

Acacia’sAcacia's operating subsidiaries acquire, develop, license and otherwise enforce patented technologies.  Acacia’sAcacia's operating subsidiaries generate license fee revenues and related cash flows from the granting of licensesintellectual property rights for the use of, or pertaining to, patented technologies that itssuch operating subsidiaries own or control.  Acacia’sAcacia's operating subsidiaries assist patentpaten t owners with the prosecution and development of their patent portfolios, the protection of their patented inventionstechnologies from unauthorized use, the generation of licensing revenue from users of their patented technologies and, if necessary, with the enforcement against unauthorized users of their patented technologies. Currently, on a consolidated basis, Acacia’sAcacia's operating subsidiaries own or control the rights to over 100171 patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.

CombiMatrix Group Split-Off Transaction and Related Discontinued Operations.  In January 2006, Acacia’s board of directors approved a plan for its former wholly owned subsidiary, CombiMatrix Corporation (“CombiMatrix”), the primary component of Acacia’s life science business (the “CombiMatrix group”), to become an independent publicly-held company.  CombiMatrix’s registration statement on Form S-1 was declared effective by the Securities and Exchange Commission (“SEC”) on June 8, 2007.  On August 15, 2007 (the “Redemption Date”), CombiMatrix was split-off from Acacia through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock in exchange for the distribution of new shares of CombiMatrix common stock, on a pro-rata basis, to the holders of Acacia Research-CombiMatrix common stock on the Redemption Date (the “Split-Off Transaction”). On the Redemption Date, every ten (10) shares of Acacia Research-CombiMatrix common stock outstanding on August 15, 2007, was redeemed for one (1) share of common stock of CombiMatrix.  Subsequent to the Redemption Date, Acacia no longer owns any equity interests in CombiMatrix and the CombiMatrix group is no longer a business group of Acacia.  As a result of the Split-Off Transaction, Acacia’s only business is its intellectual property licensing business.

As a result of the Split-Off Transaction, Acacia disposed of its investment in CombiMatrix.  Refer to Note 10A for information regarding presentation of the results of operations and cash flows for the CombiMatrix group as discontinued operations in the accompanying consolidated financial statements for all applicable historical periods presented, in accordance with guidance set forth in Statement of Financial Accounting Standards (“SFAS”) No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”).

Capital Structure.  Pursuant to the Split-Off Transaction, all outstanding shares of Acacia common stock were redeemed, and hence, all rights of holders of Acacia Research-CombiMatrix common stock ceased as of the Redemption Date, except for the right, upon the surrender to the exchange agent of shares of Acacia Research-CombiMatrix common stock, to receive new shares of CombiMatrix common stock pursuant to the exchange ratio described above.  Subsequent to the consummation of the Split-Off Transaction, Acacia’s only class of common stock outstanding is its common stock.

Prior to the Split-Off Transaction, Acacia had two classes of common stock outstanding, its Acacia Research-Acacia Technologies common stock (“AR-Acacia Technologies Stock”) and its Acacia Research-CombiMatrix common stock (“AR-CombiMatrix Stock”).  AR-Acacia Technologies Stock was intended to reflect separately the performance of Acacia’s Acacia Technologies group.  AR-CombiMatrix Stock was intended to reflect separately the performance of Acacia’s CombiMatrix group.  Although the AR-Acacia Technologies Stock and the AR-CombiMatrix Stock were intended to reflect the performance of the different business groups, they were both classes of common stock of Acacia and were not stock issued by the respective groups.

Acacia was incorporated on January 25, 1993 under the laws of the State of California. In December 1999, it changed its state of incorporation from California to Delaware.

Liquidity and Risks

Acacia’s management believes that Acacia’s consolidated cash and cash equivalents and investment balances, anticipated cash flow from operations and other external sources of available credit will be sufficient to meet Acacia’s cash requirements, on a consolidated basis, through at least March 2010.  To date, Acacia has relied primarily upon selling equity securities and payments from its licensees to generate the funds needed to finance the implementation of its plans of operation for its operating subsidiaries.

There can be no assurance that Acacia will be able to implement its future plans.  Failure by management to achieve its plans would have a material adverse effect on Acacia’s ability to achieve its intended business objectives.  Acacia may be required to obtain additional financing.  There can be no assurance that additional funding will be available on favorable terms, if at all.  If Acacia fails to obtain additional funding when needed, it may not be able to execute its business plans and its businesses may suffer.
The timing of the receipt of revenues by Acacia’s operating subsidiaries are subject to certain risks and uncertainties, including:

●  market acceptance of its operating subsidiaries’ patented technologies and services;
●  
business activities and financial results of its licensees;
●  
technological advances that may make its patented technologies obsolete or less competitive;
●  
increases in operating costs, including costs for legal services, engineering and research and personnel;
●  
the availability and cost of capital; and
●  
governmental regulation that may restrict Acacia’s business.

Acacia’s success also depends on its operating subsidiaries’ ability to protect their intellectual property.  The Company’s operating subsidiaries rely on their proprietary rights and their protection.  Although reasonable efforts will be taken to protect Acacia’s operating subsidiaries’ proprietary rights, the complexity of international trade secret, copyright, trademark and patent law, and common law, coupled with limited resources and the demands of quick delivery of technologies to market, create risk that these efforts will prove inadequate.  Accordingly, if Acacia’s operating subsidiaries are unsuccessful with litigation to protect their intellectual property rights, the future consolidated revenues of Acacia could be adversely affected.


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Accounting Principles and Fiscal Year End.  The consolidated financial statements and accompanying notes are preparedp repared on the accrual basis of accounting in accordance with generally accepted accounting principles in the United States of America.  Acacia has a December 31 fiscal year end.

Principles of Consolidation.  The accompanying consolidated financial statements include the accounts of Acacia and its wholly ownedand majority-owned and controlled subsidiaries. Material intercompany transactions and balances have been eliminated in consolidation. The cost
Noncontrolling interests in Acacia’s majority-owned operating subsidiaries ("noncontrolling interests") are separately presented as a component of stockholders’ equity in the consolidated statements of financial position for the applicable periods presented.  Consolidated net income or (loss) is adjusted to include the net (income) or loss attributed to noncontrolling interests in the consolidated statements of operations for the applicable periods presented.  Refer to the accompanying consolidated financial statements for total noncontrolling interests, and net income attributable to noncontrolling interests, for the applicable periods presented.
Change in Account ing Policy for Term Agreements. Effective October 1, 2009, the Company elected to change its method is used where Acacia maintains ownership interests of less than 20%accounting for its term agreements to recognize revenue when delivery of the intellectual property rights and does not exercise significant influence over the investee.all other arrangement deliverables has substantially occurred. Refer to Note 8 for additional information.

Revenue Recognition.  Acacia recognizes revenue in accordance with Staff Accounting Bulletin No. 104, “Revenue Recognition” (“SAB No. 104”) and related authoritative pronouncements.  Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been substantially performed pursuant to the terms of the license agreement, (iii) amounts are fixed or determinable, and (iv) the collectibility of amounts is reasonably assured.

Revenues generated from license agreements are recognized in the period earned, provided that amounts are fixed or determinable and collectibility is reasonably assured.  Under the terms of Acacia’s license agreements, Acacia’s operating subsidiaries grant non-exclusive licenses for the use of patented technologies, which they own or control.  In general, pursuant to the terms of the agreements with licensees, upon the grant of the licenses, Acacia has no further obligations with respect to the licenses granted.  License fees paid to and recognized as revenue by Acacia’s subsidiaries are non-refundable.

ACACIA RESEARCH CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Certain license agreementsarrangements provide for the payment of contractually determined paid-up license fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by Acacia's operating subsidiaries.  These rights typically include some combination of the following:  (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by Acacia’sAcacia's operating subsidiaries.  Certain of the agreements also provide for future royalties or additional required payments based on future activities.  Generally, the execution of these license agreements also provide forsubsidiaries, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and (iv) the dismissal of any pending litigation.  The intellectual property rights granted may be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment.  Pursuant to the terms of these agreements, Acacia’sAcacia's operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future licenselicenses, covenants-not-to-sue, releases, and related releases,other deliverables, including no express or implied obligation on Acacia’sAcacia's operating subsidiaries’subsidiaries' part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the licenselicenses, covenants-not-to-sue, releases, and releasesother significant deliverables upon execution of the agreement.agreement, or upon receipt of the minimum upfront payment for term agreement renewals.  As such, the earnings process is complete and revenue is recognized upon the execution of the agreement , when collectibility is reasonably

Certain of the Company's revenue arrangements provide for future royalties or additional required payments based on future licensee activities.  Additional royalties are recognized in revenue upon resolution of the related contingency provided that all revenue recognition criteria, as described above have been met.  Amounts of additional royalties due under these license agreements, if any, cannot be reasonably estimated by management.
Certain of the Company's revenue arrangements provide for the calculation of license fees based on a licensee’s actual quarterly sales or actual per unit activity, applied to a contractual royalty rate.r ate.  Licensees that pay license fees on a quarterly basis generally report actual quarterly sales or actual per unit activity information and related quarterly license fees due within 30 to 45 days after the end of the quarter in which such sales or activity takes place.  The amount of license fees due under these license agreementsrevenue arrangements each quarter cannot be reasonably estimated by management.  Consequently, Acacia’s operating subsidiaries recognize revenue from these licensing agreementsrevenue arrangements on a three-month lag basis, in the quarter following the quarter of sales or per unit activity, provided amounts are fixed or determinable and collectibility is reasonably assured. The lag method described above allows for the receipt of licensee royalty reports prior to the recognition of revenue.

Certain license agreements provide for the payment of a minimum upfront annual license fee at the inception of each annual license term.  Minimum upfront annual license fees are generally determined based on a licensee’s estimated annual sales or a licensee’s base level of per unit activity.  These minimum upfront annual license fee payments are deferred and amortizedAmounts related to revenue on a straight-line basis over the annual license term.  To the extent actual annual royalties, determined and reported in accordance with the terms of the respective agreements, exceed the minimum upfront annual license fees paid, the additional royalties are recognized in revenue in the quarter following the quarter in which the base per unit activity was exceeded or the quarter following the annual license term, depending on the terms of the respective agreement, provided that amounts are fixed or determinable and collectibility is reasonably assured.  Amounts of additional royalties due under these license agreements, if any, cannot be reasonably estimated by management.
License fee payments receivedarrangements that do not meet the revenue recognition criteria described above are deferred until the revenue recognition criteria are met.
Acacia assesses the collectibility of license fees receivable based on a number of factors, including past transaction history and credit-worthiness of licensees.  If it is determined that collection is not reasonably assured, the fee is recognized when collectibility becomes reasonably assured, assuming all other revenue recognition criteria have been met, which is generally upon receipt of cash.

Cost of RevenuesFair Value Measurements.  Effective January 1, 2008, Acacia adopted SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”).  SFAS No. 157 establishes a common definition for fair valueCost of revenues include the costs and expenses incurred in connection with Acacia's patent licensing and enforcement activities, including inventor royalties paid to be appliedoriginal patent owners, contingent legal fees paid to U.S. generally accepted accounting principles guidance requiring use of fair value, establishes a framework for measuring fair value,external patent counsel, other patent-related legal expenses paid to external patent counsel, licensing and expands disclosure about such fair value measurements.  This statement applies whenever other accounting pronouncements require or permit fair value measurements.  The adoption of SFAS No. 157 did not have a material impact on Acacia’s consolidated financial position, results of operations and cash flows.  In February 2008, the FASB issued FSP SFAS No. 157–1 which amends SFAS No. 157 to exclude FASB Statement No. 13, “Accounting for Leases”,enforcement related research, consulting and other accounting pronouncements that address fair value measurements for purposesexpenses paid to third parties and the amortization of lease classification or measurementpatent-related acquisition costs.  These costs are included under Statement 13.  In February 2008, the FASB issued FSP SFAS No. 157-2 (“FSP 157-2”) which would delay the effective datecaption “Cost of SFAS No. 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair valuerevenues” in the financialaccompanying consolidated statements on a recurring basis (at least annually).

Inventor Royalties and Contingent Legal Expenses. In connection with the acquisition of certain patents and patent rights, certain of Acacia's operating subsidiaries executed related agreements which grant to the former owners of the respective patents or patent rights, the right to receive inventor royalties based on future net revenues (as defined in the respective agreements) generated as a result of licensing and otherwise enforcing the respective patents or patent portfolios.  Inventor royalties are expensed in the consolidated statements of operations in the period that the related revenues are recognized.  In certain instances, pursuant to the terms of the underlying inventor agreements, costs paid by Acacia's operating subsidiaries to acquire patents are recoverable from future net revenues.  Patent ac quisition costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statements of operations.  Any unamortized patent acquisition costs recovered from net revenues are expensed in the period recovered, and included in amortization expense in the consolidated statements of operations.
Acacia's operating subsidiaries may retain the services of law firms that specialize in intellectual property licensing and enforcement and patent law in connection with their licensing and enforcement activities.  These law firms may be retained on a contingent fee basis whereby such law firms are paid on a scaled percentage of any negotiated fees, settlements or judgments awarded based on how and when the fees, settlements or judgments are obtained.   Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, Acacia's operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.  Legal fees advanced by contingent law firms that are required to be paid in the event that no license recoveries are obtained are expensed as incurred and included in liabilities in the consolidated balance sheets.
The economic terms of the inventor agreements, operating agreements and contingent legal fee arrangements associated with the patent portfolios owned or controlled by Acacia's operating subsidiaries, if any, including royalty rates, contingent fee rates and other terms, vary across the patent portfolios owned or controlled by such operating subsidiaries.  Inventor royalties, payments to noncontrolling interests and contingent legal fees expenses fluctuate period to period, based on the amount of revenues recognized each period, the terms and conditions of revenue agreements executed each period and the mix of specific patent portfolios with varying economic terms and obligations generating revenues each

period. Inventor royalties, payments to noncontrolling interests and contingent legal fees expenses will continue to fluctuate and may continue to vary significantly period to period, based primarily on these factors.
 
SFAS No. 157 definesDuring the year ended December 31, 2010, A cacia entered into significant agreements with unrelated third parties resolving pending patent matters that resulted in the grant of certain intellectual property rights and recognition of revenues, the majority of which were not subject to inventor royalty and contingent legal fee arrangements, as well as the grant of licenses from certain of Acacia's operating subsidiaries and recognition of revenues that were subject to inventor royalties and contingent legal fee arrangements.  Revenues recognized subject to inventor royalties and contingent legal fees are based on a determination by the respective operating subsidiaries.
Fair Value Measurements. U.S. generally accepte d accounting principles define fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. SFAS No. 157date, and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. SFAS No. 157 established aThe three-level hierarchy of valuation techniques usedestablished to measure fair value, is defined as follows:

●  
  ;Level 1 - Observable Inputs:  Quoted prices in active markets for identical investments;
●  Level 2 - Pricing Models with Significant Observable Inputs:  Other significant observable inputs, including quoted prices for similar investments, interest rates, credit risk, etc.; and
●  Level 3 - Unobservable Inputs:  Significant unobservable inputs, including the entity’s own assumptions in determining the fair value of investments.
SFAS No. 157 requires the use ofThe Company uses observable market inputs (quoted market prices) when measuring fair value and requiresis required to use a Level 1 quoted price to be used to measure fair value whenever possible.  Refer to Note 3 for a summary of marketable securities held as of December 31, 20082010 and 2007.2009.  Refer to Note 7 for information on the determination of fair value for auctionauct ion rate securities held as of December 31, 2008.2010 and 2009.

Cash and Cash Equivalents.  Acacia considers all highly liquid, short-term investments with original maturities of three months or less when purchased to be cash equivalents.  At December 31, 2008,For the periods presented, Acacia’s cash equivalents are comprised of investments in AAA rated money market funds that invest in U.S. Treasuryfirst-tier only securities, and obligationswhich primarily includes: domestic commercial paper, securities issued or guaranteed by the U.S. Government.U.S. government or its agencies, U.S. bank obligations, and fully collateralized repurchase agreements. Acacia’s cash equivalents are measured at fair value using quoted prices that represent Level 1 inputs under SFAS No. 157.inputs.

Investments in Marketable Securities.  Acacia’s marketable securities are typically held in a variety of interest bearing instruments including U.S. government debt securities, high-grade corporate bonds, commercial paper, auction rate securities, certificates of deposit and other high-credit quality marketable securities.  Investments in securities with original maturities of greater than three months and less than one year and other investments representing amounts that are available for current operations are classified as short-term investments.  Investmentsinvestments, unless there are classified into categoriesindications that such investments may not be readily sold in accordance with the provisions of SFAS No. 115, “Accounting for Certain Investments in Debtshort term. At Decembe r 31, 2010 and Equity Securities” (“SFAS No. 115”).  At December 31, 2008 and 2007,2009, all of Acacia’s investments are classified as available-for-sale, which are reported at fair value in accordance with SFAS No. 157, with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders’ equity until realized.  Realized and unrealized gains and losses are recorded based on the specific identification method.  The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity.  Such amortization is included in interest income (expense).  Interest and dividends on all securities are included in interest income.  Refer to Note 7 for information on the fair value and classification of auction rate securities held as of December 31, 2008.2010 and 2009.

Impairment of Marketable Securities.Acacia evaluates its investments in marketable securities for potential impairment, employing a systematic methodology on a quarterly basis that considers available quantitative and qualitative evidence. If the cost or carrying value of an investment exceeds its estimated fair value, the Company evaluates, among other factors, general market conditions, credit quality of instrument issuers, the duration and extent to which the fair value is less than cost, and the Company's intent and ability to hold, or plans or ability to sell. Fair value is estimated based on publicly available market information or other estimates determined by management. Investments are considered to be impaired when a decline in fair value is estimated to be other-than-temporary. Acacia reviews impairments associated with its investments in marketablemark etable securities in accordance with Emerging Issues Task Force (“EITF”) 03-1 and FSP SFAS 115-1 and 124-1, “The Meaning of Other-Than-Temporary-Impairment and Its Application to Certain Investments,” to determinedetermines the classification of any impairment as “temporary”temporary or “other-than-temporary.”   For investments classified as available-for-sale, unrealized losses that are other than temporary are recognized in the consolidated statements of operations and comprehensive loss (hereinafter “consolidated statements of operations”).other-than-temporary.   An impairment is deemed other than temporaryother-than-temporary unless (a) Acacia has the ability and intent to hold an investment for a period of time sufficient for recovery of its carrying amount and (b) positive evidence indicating that the investment's carrying amount is recoverable within a reasonable period of time outweighs any evidence to the contrary. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, the carrying amount of the investment is recoverable within a reasonable period of time. For investments classified as available-for-sale, unrealized losses that are other-than-temporary are recognized in the consolidated statements of operations.   Refer to Note 7 for disclosures regarding investments in auction rate securities.

In the event the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded.  If an asset is determined to be impaired,imp aired, the loss is measured based on quoted market prices in active markets, if available.  If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows.

Fair Value of Financial Instruments.  The carrying value of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses approximateapproximates their fair valuevalues due to their short-term maturity.  Refer to Note 7 for disclosures regarding investments in auction rate securities.   maturities.

Stock-Based Compensation.Effective January 1, 2006, Acacia adopted the provisions of SFAS No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123R”), which sets forth the accounting requirements for “share-based” compensation payments to employees and non-employee directors and requires that compensation cost relating to share-based payment transactions be recognized in the statement of operations. The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (generally the vesting period of the equity award) which is generally two to four years.

The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model. The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units granted and the grant date market price of the underlying common stock.

Acacia estimates pre-vesting option forfeitures at the time of grant and reflects the impact of estimated pre-vesting option forfeitures on compensation expense recognized.  To the extent that actual results differ from Acacia’s estimates, such amounts are recorded as cumulative adjustments in the period the estimates are revised.  

Acacia adopted SFAS No. 123R using the modified prospective transition method.  Under this transition method, compensation cost recognized for the periods presented includes: (i) compensation cost for all stock-based awards granted prior to, but not yet vested as of January 1, 2006 (based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123 and previously presented in the pro forma footnote disclosures), and (ii) compensation cost for all stock-based awards granted subsequent to January 1, 2006 (based on the grant-date fair value estimated in accordance with the provisions of SFAS No. 123R).

The fair value of stock options granted during the years ended December 31, 2007 and 2006 were estimated using the Black-Scholes option-pricing model, assuming weighted-average risk free interest rates of 4.64% and 4.30%, expected terms of 5.71 years and 6 years and volatility of 68% and 75%, respectively.  There were no stock options granted during the year ended December 31, 2008.  Refer to Note 11 for information on stock-based awards granted for the periods presented.

Acacia adopted the alternative transition method provided in FASB Staff Position No. 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.”  The alternative transition method includes a simplified method to establish the beginning balance of the additional paid-in-capital pool related to the tax effects of employee stock-based compensation which is available to absorb tax deficiencies recognized subsequent to the adoption of SFAS 123R.

Income Taxes.  Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in Acacia’s consolidated financial statements or consolidated tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized.

Effective January 1, 2007, Acacia adopted FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes,” which clarifies theUnder U.S. generally accepted accounting for uncertainty in income taxes recognized in the financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” FIN 48 provides guidance on the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosures, and transition.  In accordance with FIN 48,principles, a tax position is a position in a previously filed tax return or a position expected to be taken in a future tax filing that is reflected in measuring current or deferred income tax assets and liabilities. Tax positions shall beare recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position will be sustained upon examination. Tax positions that meet the more likely than not threshold should beare measured using a probability weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement.  The adoption of FIN 48 did not have a material impact on Acacia’s consolidated financial position, results of operations or cash flows.

The total amount of unrecognized tax benefits as of December 31, 20082010, 2009 and 2007,2008 was $85,000, $85,000 and January 1, 2007 was $75,000, $67,000 and $56,000, respectively, all of which, if recognized, would affect the effective tax rate. 
 
Acacia recognizes interest and penalties with respect to unrecognized tax benefits in income tax expense.  Acacia has identified no uncertain tax position for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within 12 months.
 
Acacia is subject to taxation in the U.S. and various state jurisdictions.  With no material exceptions, Acacia is no longer subject to U.S. federal or state examinations by tax authorities for years before 2002.  2005.

At December 31, 2008,2010, Acacia had U.S. federal and state income tax net operating loss carryforwards ("NOL") as summarized atin Note 9.10.  Due to uncertainties surrounding Acacia’s ability to generate future taxable income to realize these assets, a full valuation allowance has been established to offset its net deferred tax assets.  All net operating loss carryforwards (“NOLs”) and tax credits generated by the continuing operations of Acacia and its operating subsidiaries have been retained by Acacia subsequent to the Split-Off Transaction.  Subsequent to the Split-Off Transaction, all NOLs and tax credits generated by CombiMatrix and its subsidiaries have been retained by CombiMatrix and are not available to Acacia.

If a deduction reported on a tax return for an equity-based i ncentive award exceeds the cumulative compensation cost for those instruments recognized for financial reporting purposes, any resulting realized tax benefit that exceeds the previously calculated deferred tax asset for those instruments is considered an excess tax benefit, and is recognized as additional paid-in capital.
 
Utilization of the NOL and research and development (“R&D”) credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change” as defined by Section 382 of the Code results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups.  Since Acacia’s formation, it has raised capital through the issuance of capital stock on several occasions (both before and after its public offering) which, combined with the purchasing stockholders’ subsequent disposition of those shares, may have resulted in such an ownership change, or could result in an ownership change in the future upon subsequent disposition.

Acacia has not completed a study to assess whether an ownership change has occurred or whether there have been multiple ownership changes since its formation due to the complexity and cost associated with such a study, and the fact that there may be additional such ownership changes in the future.  If Acacia has experienced an ownership change at any time since its formation, utilization of the NOL or R&D credit carryforwards would be subject to an annual limitation under Section 382 of the Code, which is determined by first multiplying the value of Acacia’s stock at the time of the ownership change by the applicable long-term, tax-exempt rate, and then could be subject to additional adjustments, as required. Any limitation may result in expiration of a portion of the NOL or R&D credit carryforwards before utilization. Further, until a study is completed and any limitation known, no amounts are being considered as an uncertain tax position or disclosed as an unrecognized tax benefit under FIN 48. Due to the existence of a full valuation allowance, future changes in Acacia’s unrecognized tax benefits will not impact its effective tax rate. Any carryforwards that will expire prior to utilization as a result of such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance.

Comprehensive Income (Loss).  Comprehensive income (loss) is the change in equity from transactions and other events and circumstances other than those resulting from investments by owners and distributions to owners.

Segment Reporting.  Acacia uses the management approach, which designates the internal organization that is used by management for making operating decisions and assessing performance as the basis of Acacia’s reportable segments.  Acacia’s intellectual property licensing and enforcement business constitutes its single reportable segment.

Use of Estimates.  The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.  Acacia believes that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, stock-based compensation expense, valuation of long-lived and intangible assets and impairment of marketable securities, require its most difficult, subjective or complex judgments.

Earnings (Loss) Per Share.Share .  Basic earningsincome (loss) per share for each class of common stock is computed by dividing the income or loss allocated to each class of common stock bybased upon the weighted-average number of common shares outstanding, shares of that class of commonexcluding unvested restricted stock.  Diluted earningsincome (loss) per share is computed by dividing the income or loss allocated to each class of common stock bybased upon the weighted-average number of outstandingcommon shares of that class of common stock,outstanding, including the dilutive effect of common stock equivalents.equivalents outstanding during the periods.  Potentially dilutive common stock equivalents primarily consist of employee stock options, unvested restricted stock, and restricted stock units and(“Equity-based Incentive Awards”).
Potentially dilutive common stock purchase warrants (AR-CombiMatrix stock only).

The earnings or losses allocated to each class of common stockshares from Equity-based Incentive Awards are determined by Acacia’s boardapplying the treasury stock method to the a ssumed exercise of directors. This determination is generally based onoutstanding employee stock options, and the net income or loss amountsassumed vesting of the corresponding group determined in accordance with accounting principles generally accepted in the United States of America, consistently applied.  Acacia believes this method of allocation to be systematicoutstanding unvested restricted stock and reasonable.restricted stock units.

Recent Accounting Pronouncements.In March 2008,October 2009, the FASBFinancial Accounting Standards Board issued SFAS No. 161, “Disclosures About Derivative Instrumentsnew accounting guidance which amends existing revenue recognition accounting pronouncements and Hedging Activities - an amendment of FASB Statement No. 133,” (“SFAS No. 161”). SFAS No. 161 expandsprovides accounting principles and application guidance on whether multiple deliverables exist, how the disclosure requirements in SFAS No. 133 regarding an entity’s derivative instruments and hedging activities. SFAS No. 161 is effective for Acacia’s fiscal year beginning January 1, 2009. Acacia does not expect the adoption of SFAS No. 161 to have a material impact on its consolidated financial position, results of operations or cash flows.
In April 2008, the FASB issued FASB Staff Position FAS 142-3, “Determination of Useful Life of Intangible Assets” (“FSP 142-3”). FSP 142-3 amends the factors thatarrangement should be considered in developingseparated, and the renewal or extension assumptions usedconsideration allocated. This guidance eliminates the requirement to establish the fair value of undelivered products and services and instead provides for separate revenue recognition based upon management's estimate of the selling price for an undelivered item when there is no other means to determine the useful lifefair value of that undelivere d item. Previous accounting principles required that the fair value of the undelivered item be the price of the item either sold in a separate transaction between unrelated third parties or the price charged for each item when the item is sold separately by the vendor. This was difficult to determine when the product was not individually sold because of its unique features. If the fair value of all of the elements in the arrangement was not determinable, then revenue was deferred until all of the items were delivered or fair value was determined. The accounting guidance will be applied prospectively and will become effective for the Company no later than January 1, 2011. Early adoption is allowed. Acacia elected to adopt this accounting guidance effective January 1, 2010. The adoption of this standard did not have an impact on Acacia's financial position or results of operations.
&nb sp;
On January 1, 2010, Acacia adopted the provisions of a recognized intangible asset under FAS No. 142, “Goodwillnew accounting standard which provides amendments to previous guidance on the consolidation of variable interest entities. This standard clarifies the characteristics that identify a variable interest entity (“VIE”) and Other Intangible Assets.” FSP 142-3changes how a reporting entity identifies a primary beneficiary that would consolidate the VIE from a quantitative risk and rewards calculation to a qualitative approach based on which variable interest holder has a controlling financial interest and the ability to direct the most significant activities that impact the VIE's economic performance. This standard requires the primary beneficiary assessment to be performed on a continuous basis. It also requires expanded disclosure regardingadditional disclosures about an entity's involvement with a VIE, restrictions on the determination of intangible asset useful lives. FSP 142-3VIE's assets and liabilities that are inclu ded in the reporting entity's condensed consolidated balance sheet, significant risk exposures due to the entity's involvement with the VIE, and how its involvement with a VIE impacts the reporting entity's condensed consolidated financial statements. The standard is effective for fiscal years beginning after DecemberNovember 15, 2008. Earlier adoption is not permitted. Acacia is currently evaluating the potential impact of the2009. The adoption of FSP 142-3, if any, on its consolidated financial position, results of operations and cash flows.

In May 2008, the FASB issued SFAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles” (“SFAS No. 162”).  SFAS No. 162 identifies the sources of accounting principles and the framework for selecting the principles used in the preparation of financial statements that are presented in conformity with generally accepted accounting principles in the United States of America. SFAS No. 162 will become effective 60 days following the SEC’s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, “The Meaning of Present Fairly in Conformity With Generally Accepted Accounting Principles.” Acacia doesthis standard did not expect the adoption of SFAS No. 162 to have a material impact on its consolidatedAcacia's financial position or results of operations or cash flows.operations.

In June 2008, the FASB issued FSP EITF 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities” (“FSP EITF 03-6-1”).  FSP EITF 03-6-1 clarifies whether instruments, such as restricted stock, granted in share-based payments are participating securities prior to vesting.  Such participating securities must be included in the computation of earnings per share under the two-class method as described in SFAS No. 128, “Earnings per Share.”  FSP EITF 03-6-01 requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings per share.  FSP EITF 03-6-1 is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2008, and requires a company to retrospectively adjust its earnings per share data.  Early adoption is not permitted. Acacia is currently evaluating the potential impact of the adoption of FSP EITF 03-6-1, if any, on its current and prior period loss per share computations.

In October 2008, the FASB issued FSP FAS 157-3, “Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active” (“FSP FAS 157-3”). FSP FAS 157-3 clarifies the application of SFAS No. 157 in a market that is not active and provides an example to illustrate key considerations in determining the fair value of a financial asset when the market for that financial asset is not active. FSP FAS 157-3 is effective upon issuance, including prior periods for which financial statements have not been issued. Acacia adopted FSP FAS 157-3 for the period ended September 30, 2008 and the adoption did not have a significant impact on its consolidated financial position, results of operations or cash flows.

In December 2008, the FASB issued FASB Staff Position (“FSP”) FAS 140-4 and FIN 46(R)-8, “Disclosure by Public Entities (Enterprises) About Transfers of Financial Assets and Interests in Variable Interest Entities.” FSP FAS 140-4 amends SFAS No. 140 to require public companies to provide additional disclosures about transferor’s continuing involvement with transferred financial assets. It also amends FIN 46R by requiring public companies to provide additional disclosures regarding their involvement with variable interest entities. FSP FAS 140-4 is effective for Acacia’s fiscal year beginning January 1, 2009. Acacia does not expect the adoption of FSP to have a material impact on its consolidated financial position, results of operations or cash flows.
In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (“SFAS No. 141R”). SFAS No. 141R establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and the goodwill acquired.  SFAS No. 141R also establishes disclosure requirements to enable the evaluation of the nature and financial effects of business combinations. SFAS No. 141R is effective for Acacia as of January 1, 2009. Acacia does not expect the adoption of SFAS No. 141R to have a material impact on its consolidated financial position, results of operations or cash flows.
In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements—an amendment of Accounting Research Bulletin No. 51 (“SFAS No. 160”). SFAS No. 160 establishes accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a parent’s ownership interest, and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS No. 160 also establishes disclosure requirements that clearly identify and distinguish between the interests of the parent and the interests of the noncontrolling owners.

Acacia does not expect the adoption of SFAS No. 160 to have a material impact on its consolidated financial position, results of operations or cash flows.
In December 2007, the FASB ratified the Emerging Issues Task Force consensus on EITF Issue No. 07-1, “Accounting for Collaborative Arrangements” (EITF Issue No. 07-1”) that discusses how parties to certain collaborative arrangements should account for various activities. The consensus indicates that costs incurred and revenues generated from transactions with third parties should be reported by the collaborators on the respective line items in their income statements pursuant to EITF Issue No. 99-19, “Reporting Revenue Gross as a Principal Versus Net as an Agent.”  Additionally, the consensus provides that income statement characterization of payments between the participants in a collaborative arrangement should be based upon existing authoritative pronouncements; analogy to such pronouncements if not within their scope; or a reasonable, rational, and consistently applied accounting policy election. EITF Issue No. 07-1 is effective for Acacia beginning January 1, 2009 and is to be applied retrospectively to all periods presented for collaborative arrangements existing as of the date of adoption. Acacia does not expect EITF Issue No. 07-1 to have a material impact on its consolidated financial position, results of operations or cash flows.

Pursuant to provisions of the underlying inventor agreements, certain operating subsidiaries recovered up-front patent portfolio acquisition costs from applicable net licensing proceeds, prior to the scheduled amortization of such up-front patent portfolio acquisition costs, resulting in the acceleration of amortization expense for the applicable patent related assets. For the years ended December 31, 2010, 2009 and 2008, accelerated amortization expense related to the recovery of up-front patent acquisition costs totaled $1,171,000, $42,000 and $155,000, respectively.
In 2010, pursuant to the terms of the respective inventor agreement, an Acacia operating subsidiary elected to terminate its rights to a patent portfolio, resulting in the acceleration of amortization expense for the patent related asset totaling $338,000.

7.  FAIR VALUE MEASUREMENTS AND AUCTION RATE SECURITIES
 
In September 2006, the FASB issued SFAS No. 157.  SFAS No. 157 defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States of America, and expands disclosures about fair value measurements. Acacia adopted the provisions of SFAS No. 157 effective January 1, 2008, for financial instruments. Although the adoption of SFAS No. 157 did not materially impact Acacia’s financial condition, results of operations, or cash flows, SFAS No. 157 requires Acacia to provide additional disclosures as part of its consolidated financial statements.
As of December 31, 2008,2010 and 2009, Acacia held investment grade auction rate securities with a par value totaling $3,725,000. Acacia’s auction rate securities consist$2,485,000 and $2,685,000, respectively, consisting of high credit quality securities issued by closed-end investment companies with portfolio asset coverage of at least 200%, and auction rate investments backed by student loans, issued under programs such as the Federal Family Education Loan Program, all of which carry credit ratings of AAA (S&P and Moody’s).  Auction rate securities are classified as available-for-sale securities and reflected at fair value in accordance with the requirements of SFAS No. 157.  value.  
 
Historically, Acacia’s auction rate securities were recorded at cost, which approximated their fair market value due to their variable interest rates, which typically reset every 7 to 35 days, despite the long-term nature of their stated contractual maturities.  The Dutch auction process that resets the applicable interest rate at predetermined calendar intervals is intended to provide liquidity to the holder of auction rate securities by matching buyers and sellers within a market context enabling the holder to gain immediate liquidity by selling such interests at par or rolling over their investment. If there is an imbalance between buyers and sellers, the risk of a failed auction exists.  Due to current liquidity issues in the global credit and capital markets, these securities have continued to experienceexp erienced failed auctions since February 2008.  In suchthe case of a failure, the auction rate securities continue to pay interest at the maximum contractual rate in accordance with their terms; however, Acacia may not be able to access the par value of the invested funds until a future auction of these investments is successful, the security is called by the issuer, or a buyer is found outside of the auction process.

As a result of the failed auctions, there are no reliable current observable market prices available for these securities for purposes of establishing fair market value as of December 31, 2008.2010 and 2009.  As a result, the fair values of these securities arewere estimated utilizing an analysis of certain unobservable inputs and by reference to a discounted cash flow analysis as of December 31, 2008.2010 and 2009.  These analyses considered, among other items, the underlying structure of each security, the collateral underlying the security investments, the creditworthiness of the counterparty, the present value of future principal and contractual interest payments discounted at rates considered to be reflective of current market conditions, consideration of the probabilities of default, continued auction failure, or repurchase or redemption at par for each period, and estimates of the time period over which liquidity related issues will be resolved.  Observable market data for instruments with similar characteristicscharacteri stics to Acacia’s auction rate securities was also considered when possible.
 
At December 31, 2008, the par value of auction rate securities collateralized by student loan portfolios totaled $2,750,000.  As a result of the liquidity issues associated with the failed auctions, Acacia estimates that the fair value of these auction rate securities no longer approximates their par value.  Due to the estimate that the market for these student loan collateralized instruments may take in excess of twelve months to fully recover, Acacia has classified these investments as noncurrent in the accompanying December 31, 2008 consolidated balance sheet,sheets, and as a result of the analysis described above, recorded a netan other-than-temporary loss of $250,000$296,000 and $263,000 in the accompanying statements of operations for the yearyears ended December 31, 2008.
At2009 and December 31, 2008, respectively.   As a result of partial redemptions at par on certain of these auction rate securities subsequent to June 30, 2008, Acacia recorded net realized gains totaling $32,000 (original recognized unrealized loss was $49,000), $13,000 and $13,000 for 2010, 2009 and 2008, respectively reflecting a partial recovery of the par valueother-than-temporary loss originally recorded on these securities.  As ofDecember 31, 2010, the net other-than-temporary loss on auction rate securities collateralized by student loan portfolios totaled $484,000.

All of Acacia’s auction rate securities issued by high credit quality closed-end investment companies totaled $975,000.  Despite the reduction in liquidity resulting from the failure of auctions for these securities since February 2008, the issuers of these auction rate securities havewere redeemed at par approximately 66% of the securities held by Acacia since February 2008, and have indicated that they continue to evaluate ways to provide additional liquidity to their auction rate security holders.  Additionally, these securities continue to be AAA rated and the underlying funds continue to meet certain specified asset coverage tests required by the rating agencies, as well as the 200% asset coverage test with respect to auction rate securities set forth in the Investment Company Act of 1940, as amended.  However, due to the impact of the reduced liquidity associated with these securities as of December 31, 2008, Acacia recorded an other-than-temporary loss on these auction rate securities of2009, resulting in realized gains totaling $236,000 in the accompanying statements of operations for the year ended December 31, 2008, and  classified2009, reflecting the full recovery of the other-than-te mporary loss originally recorded on these securities as noncurrent assets in the accompanying December 31, 2008 consolidated balance sheet.securities.
 
Acacia will continue to monitor and evaluate its investments in auction rate securities for any further potential impairment in future periods.  If it is determined that any future valuation adjustments are other-than-temporary, Acacia would record additional charges to earnings as appropriate.

As a result of the change in market conditions, during the first quarter of 2008, Acacia modified the valuation methodology for auction rate securities to include consideration of the factors discussed above and reference to a discounted cash flow analysis.  Accordingly, these securities changed from Level 1 to Level 3 within SFAS No. 157’s hierarchy since the initial adoption of SFAS No. 157 at January 1, 2008.  The following table presents the assets measured at fair value on a recurring basis using significant unobservableunobservabl e inputs (Level 3) as defined in SFAS No. 157 at December 31, 20082010 and 2009 (in thousands):

8.  CHANGE IN ACCOUNTING POLICY
8.
Certain revenue agreements provide for the payment of a minimum upfront fee at the inception of each contractual term in consideration for the respective intellectual property rights granted, hereinafter referred to as “term agreements.” Effective October 1, 2009, the Company elected to change its method of accounting for its term agreements to recognize revenue when delivery of the intellectual property rights and all other arrangement deliverables has substantially occurred, which is typically at the time of execution of the related term agreement, or upon receipt of the applicable minimum upfront renewal payment, and when all other revenue recognition criteria, as described in Note 2 above, have been met.   Prior to the change in the Company’s method of accounting, fees for term agreements were deferred and amortized to revenue on a straight-line basis over the applicable contractual license term.  The new method was adopted as it provides a consistent approach to accounting for all of the Company’s license ar rangements with similar significant terms and conditions and more closely reflects the culmination of the earnings process associated with these revenue arrangements.
The change was accounted for through retrospective application of the new accounting policy as of January 1, 2009.  The effect of applying the new accounting policy to term agreements in periods prior to fiscal year 2009 was not material.  Accordingly, the Company’s consolidated financial statements for years ending prior to January 1, 2009 have not been retroactively adjusted for this change in accounting policy.

CapitalRepurchase of Restricted Common Stock

In connection withMay 2009, Acacia’s board of directors approved a restricted stock vesting net issuance program.  Under the consummationprogram, upon the vesting of the Split-Off Transaction, on August 15, 2007, CombiMatrix was split-off from Acacia through the redemption of all outstandingunvested shares of AR-CombiMatrix Stock in exchange for the distribution of new shares of CombiMatrix common stock.  As a result of, and immediately following, the consummation of the Split-Off Transaction, Acacia’s only class ofrestricted common stock, outstanding was its AR-Acacia Technologies stock.  On May 20, 2008, Acacia’s stockholders approved an amendment and restatement of Acacia’s Certificate of Incorporation to eliminate all references to the AR-CombiMatrix Stock and all provisions relating to the rights and obligations pursuant to the AR-CombiMatrix Stock.  As a result of the amendment and restatement, the name of “Acacia Research-Acacia Technologies common stock” was changed to “common stock,” and it is the only class of common stock authorized and issuable as a single class of common stock.    

Pursuant to Acacia’s Amended and Restated Certificate of Incorporation the authorized capital stock of Acacia consists of 100,000,000withheld from fully vested shares of common stock $0.001 par value, and 10,000,000otherwise deliverable to any employee-participant in Acacia’s equity compensation programs, a number of whole shares of preferred stock, $0.001 par value.  Under the terms of the Amended and Restated Certificate of Incorporation, the board of directors may determine the rights, preferences and terms of Acacia’s authorized but unissued shares of preferred stock.  Holders of common stock are entitledhaving a fair market value (as determined by Acacia as of the date of vesting) equal to one vote per share on all mattersthe amount of tax required to be voted onwithheld by law, in order to satisfy the stockholders, and to receive ratably such dividends, if any, as may be declared by the board of directors out of funds legally available therefore.

10.  ACCOUNTING FOR THE SPLIT-OFF OF COMBIMATRIX CORPORATION

In January 2006, Acacia’s board of directors approved a plan for CombiMatrix to become an independent publicly-held company.  On August 15, 2007 (the “Redemption Date”), CombiMatrix was split-off from Acacia through the redemption of all outstanding shares of AR-CombiMatrix Stock in exchange for the distribution of new shares of CombiMatrix common stock, on a pro-rata basis, to the holders of AR-CombiMatrix Stock as of the Redemption Date.  On the Redemption Date, every ten (10) shares of AR-CombiMatrix Stock outstanding on August 15, 2007, was redeemed for one (1) share of common stock of CombiMatrix.  Subsequent to the Redemption Date, Acacia no longer owns any equity interests in CombiMatrix and the two companies operate independently of each other.

As a result of the Split-Off Transaction, the CombiMatrix group is no longer a business group of Acacia.  As a result of the Split-Off Transaction, all outstanding shares of AR-CombiMatrix Stock were redeemed, and all rights of holders of AR-CombiMatrix Stock ceased as of the Redemption Date, except for the right, upon the surrender to the exchange agent of shares of AR-CombiMatrix Stock, to receive new shares of CombiMatrix common stock pursuant to the exchange ratio described above.

The Split-Off Transaction was accounted for by Acacia at historical cost.  Accordingly, no gain or loss on disposal was recognizedincrease in the accompanying consolidated statement of operationsCompany's tax expense for the year ended December 31, 2007. Included in2010, as compared to the year ended December 31, 2007 consolidated balance sheet is a charge to consolidated shareholders’ equity totaling $35,444,000, reflecting2009, reflects the distribution of Acacia’s investment in the net assets of CombiMatrix to holders of AR-CombiMatrix Stock, asimpact of the Redemption Date,suspension of the use of NOLs in California, as described above.  Acacia receivedbelow, and the calculation of tax exp ense for financial reporting purposes without the excess tax benefit related to the exercise and vesting of equity-based incentive awards during the year ended December 31, 2010.
Under U.S. generally accepted accounting principles, if a private letter rulingdeduction reported on a tax return for an equity-based incentive award exceeds the cumulative compensation cost for those instruments recognized for financial reporting purposes, any resulting realized tax benefit that exceeds the previously calculated and recognized compensation expense for those instruments is considered an excess tax benefit, and is recognized as a credit to additional paid-in capital. The deduction related to the exercise and vesting of equity-based incentive awards during the year e nded December 31, 2010 is available to offset taxable income on Acacia's 2010 consolidated tax return, as no NOLs are allowed to be utilized for California tax return purposes in 2010, as described below. Accordingly, the excess tax benefit related to the exercise and vesting of equity-based incentive awards during the year ended December 31, 2010 was credited to additional paid-in capital, not tax expense. The actual tax benefit realized for excess tax deductions resulting from the IRS with regard to the U.S. federal income tax consequences of the Split-Off Transaction to the effect that the Split-Off Transaction will be treated as a tax-free exchange under Sections 368exercise and 355 of the Code

For the period from January 1, 2007 through August 15, 2007, revenues and pre-tax loss related to CombiMatrix included in discontinued operations were $2,968,000 and $8,086,000, respectively.  The net loss from discontinued operationsvesting or equity-based incentive awards totaled $1,302,000 for the year ended December 31, 2007 includes direct costs incurred in connection with2010. As a result of the Split-Off Transaction, originally included in Acacia corporate accounts, totaling $136,000excess tax benefit realized, our state taxes payable for the year ended December 31, 2007.2010, for the 2010 tax year, totaled $170,000, primarily relating to California state minimum taxes for the 2010 tax year.

In January 2006, Acacia’s boardOctober 2010, the State of directors approvedCalifornia passed a planstate budget including provisions furthering the suspension of the use of NOLs, for its wholly owned subsidiary, CombiMatrix, to become an independent publicly-held company.  CombiMatrix’s registration statement on Form   S-1 was declared effective by the SEC on June 8, 2007. 

2010 and 2011 tax years. As a result, ofCalifornia State NOLs are not available to offset California taxable income for the Split-Off Transaction, the CombiMatrix group is no longer a business group of Acacia.  As a result of the consummation of the Split-Off Transaction, the assets, liabilities, results of operations and cash flows of CombiMatrix have been eliminated from the continuing operations of Acacia and Acacia does not have any continuing involvement in the operations of CombiMatrix.  As a result of the Split-Off Transaction, Acacia has disposed of its investment in CombiMatrix, and therefore, in accordance with guidance set forth in SFAS No. 144, Acacia’s accompanying consolidated financial statements for all historical periods presented reflect the results of operations and cash flows for CombiMatrix as discontinued operations.  CombiMatrix was previously presented as a separate operating segment of Acacia under SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.”2010 or 2011 tax years.

11.  STOCK-BASED INCENTIVE PLANS

The 2002 Acacia Technologies Stock Incentive Plan (“2002 Plan”) and the 2007 Acacia Technologies Stock Incentive Plan (“2007 Plan”) (collectively, the “Plans”) were approved by the stockholders of Acacia in December 2002 and May 2007, respectively. Both Plans allow grants of stock options, stock awards and performance shares with respect to Acacia common stock to eligible individuals, which generally includes directors, officers, employees and consultants.  Except as noted below, the terms and provisions of the Plans are identical in all material respects.

Acacia’s compensation committee administers the discretionary option grant and stock issuance programs.  The compensation committee determines which eligible individuals are to receive option grants or stock issuances under those programs, the time or times when the grants or issuances are to be made, the number of shares subject to each grant or issuance, the status of any granted option as either an incentive stock option or a non-statutory stock option under the federal tax laws, the vesting schedule to be in effect for the option grant or stock issuance and the maximum term for which any granted option is to remain outstanding.  The exercise price of options is generally equal to the fair market value of Acacia’s common stock on the date of grant.  Options generally begin to be exercisable six months to one year after grant and generally expire ten years after grant.  Stock options generally vest over two to three years and restricted shares generallygeneral ly vest in full after two to three years (generally representsrepresenting the requisite service period in accordance with SFAS No. 123R)period).

Inventor Royalties and Contingent Legal Expenses

In connection with the acquisition of certain patents and patent rights, certain of Acacia's operating subsidiaries of Acacia executed related agreements which grant to the former owners of the respective patents or patent rights, the right to receive inventor royalties based on future net license fee revenues (as defined in the respectiver espective agreements) generated as a result of licensing and otherwise enforcing the respective patents or patent portfolios.  Inventor royalties paid pursuant to the agreements are expensed in the consolidated statements of operations in the period that the related license fee revenues are recognized.  In certain instances, pursuant to the terms of the underlying inventor agreements, costs paid by Acacia’s
Acacia's operating subsidiaries to acquire patents are recoverable from future net revenues.  Patent acquisition costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statements of operations.  Any unamortized patent acquisition costs recovered from net revenues are expensed in the period recovered, and included in inventor royalties and contingent legal fees – patents in the consolidated statements of operations.

In connection with the licensing and enforcement activities of Acacia’s operating subsidiaries, they may retain the services of law firms that specialize in intellectual property licensing and enforcement and patent law.law in connection with their licensing and enforcement activities.  These law firms may be retained on a contingent fee basis in which thewhereby such law firms are paid on a scaled percentage of any negotiated license fees, settlements or judgments awarded based on how and when the license fees, settlements or judgments are obtained.   In instances where there are no recoveries from potential infringers (ie. license fees), no contingent legal fees are paid; however, Acacia’s operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.  Legal fees advanced by contingent law firms that are required to be paid in the event that no license recoveries are obtained are expensed as incurred and included in liabilities in the consolidated balance sheets.
 
Patent Enforcement and Other Litigation

Acacia is subject to claims, counterclaims and legal actions that arise in the ordinary course of business.  Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on Acacia’sAcacia's consolidated financial position, results of operations or cash flows.  OperatingCertain of Acacia's operating subsidiaries of Acacia are often required to engage in litigation to enforce their patents and patent rights.

ACACIA RESEARCH CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
  In connection with any of Acacia's operating subsidiaries' patent enforcement actions, it is possible that a defendant may request and/or a court may rule that an operating subsidiary has violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions.  In such event, a court may issue monetary sanctions against Acacia or its operating subsidiaries or award attorney's fees and/or expenses to a defendant(s), which could be material, and if required to be paid by Acacia or its operating subsidiaries, could materially harm the Company's operating results and financial position.
 
Guarantees and Indemnifications

Certain of Acacia’s operating subsidiaries have made guarantees and indemnities under which they may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business.  In connection with certain facility leases Acacia and certain of its operating subsidiaries have indemnified lessors for certain claims arising from the facilities or the leases.  Acacia indemnifies its directors and officers to the maximum extent permitted under the laws of the State of Delaware.  However, Acacia has a directors and officers insurance policy that may reduce its exposure in certain circumstances and may enable it to recover a portion of future amounts that may be payable, if any.  The duration of the guarantees and indemnities varies and, in many cases is indefinite but subject to statute of limitations.   The majority of guarantees and indemnities do not provide any limitations of the maximum potential future payments that Acacia could be obligated to make.  To date, Acacia has made no payments related to these guarantees and indemnities.  Acacia estimates the fair value of its indemnification obligations to be insignificant based on this history and therefore, have therefore, not recorded any liability for these guarantees and indemnities in the accompanying consolidated balance sheets.
