~~GLOSSARY OF TERMS~~

~~“Second Generation.” A generic term usually used in reference to voice-oriented digital wireless products, primarily mobile handsets that provide basic voice services.~~

~~2.5G~~

~~A generic term usually used in reference to fully integrated voice and data digital wireless devices offering higher data rate services and features compared to 2G.~~

“Third Generation.” A generic term usually used in reference to the generation of digital mobile devices and networks after 2G and 2.5G, which provide high speed data communications capability along with voice services.

~~Bandwidth~~

~~A range of frequencies that can carry a signal on a transmission medium, measured in Hertz and computed by subtracting the lower frequency limit from the upper frequency limit.~~

~~CDMA~~

“Code Division Multiple Access.” A method of digital spread spectrum technology wireless transmission that allows a large number of users to share access to a single radio channel by assigning unique code sequences to each user.

~~Chip~~

~~An electronic circuit that consists of many individual circuit elements integrated onto a single substrate.~~

~~Circuit~~

~~The connection of channels, conductors and equipment between two given points through which an electric current may be established.~~

~~Digital~~

~~Information transmission where the data is represented in discrete numerical form.~~

~~Digital Cellular~~

~~A cellular communications system that uses over-the-air digital transmission.~~

~~FDMA~~

“Frequency Division Multiple Access.” A technique in which the available transmission of bandwidth of a channel is divided by frequencies into narrower bands over fixed time intervals, resulting in more efficient voice or data transmissions over a single channel.

~~Frequency~~

~~The rate at which an electrical current or signal alternates, usually measured in Hertz.~~

~~Hertz~~

~~The unit of measuring radio frequency (one cycle per second).~~

~~Kbps~~

~~“Kilobits per Second.” A measure of information-carrying capacity (i.e., the data transfer rate) of a circuit, in thousands of bits.~~

~~Mbps~~

~~“Megabits per Second.” A measure of information-carrying capacity of a circuit, in millions of bits.~~

~~Modem~~

~~A combination of the words modulator and demodulator, referring to a device that modifies a signal (such as sound or digital data) to allow it to be carried over a medium such as wire or radio.~~

~~Multiple Access~~

A methodology (e.g., FDMA, TDMA, CDMA) by which multiple users share access to a transmission channel. Most modern systems accomplish this through “demand assignment,” where the specific parameter (frequency, time slot or code) is automatically assigned when a subscriber requires it.

INTERDIGITAL, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2009
(unaudited)

1.BASIS OF PRESENTATION:

In the opinion of management, the accompanying unaudited, condensed, consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the financial position of InterDigital, Inc. (collectively with its subsidiaries referred to as “InterDigital,” the “Company,” “we,” “us” or “our”) as of June 30, 2009, and the results of our operations for the three and six months ended June 30, 2009 and 2008 and our cash flows for the six months ended June 30, 2009 and 2008. The accompanying unaudited, condensed, consolidated financial statements have been prepared in accordance with the instructions for Form 10-Q and, accordingly, do not include all of the detailed schedules, information and notes necessary to state fairly the financial condition, results of operations and cash flows in conformity with generally accepted accounting principles. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Therefore, these financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s latest Annual Report on Form 10-K for the fiscal year ended December 31, 2008 (“2008 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on March 2, 2009. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. We have one reportable segment.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

For the quarterly period ended June 30, 2009, the Company has considered subsequent events through July 30, 2009, which is the date its Condensed Consolidated Financial Statements were filed with the Securities and Exchange Commission on Form 10-Q.

Reclassifications

Due to our March 30, 2009 repositioning, we reclassified our income statement presentation in order to align our operating expense classifications with our ongoing activities. We eliminated theGeneral and administrativeandSales and marketingclassifications within Operating Expenses and created theSelling, general and administrativeclassification. All costs previously reported underGeneral and administrativehave been reclassified toSelling, general and administrative,whileSales and marketingcosts have been reclassified betweenSelling, general and administrativeandPatent administration and licensing. Additionally, we have reclassified portions of ourDevelopmentcosts toPatent administration and licensing. The table below displays the as previously reported and as reclassified operating expenses.

There have been no material changes in our existing accounting policies from the disclosures included in our 2008 Form 10-K, except as discussed below.

New Accounting Pronouncements

SFAS No. 141-R

In December 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 141-R,Business Combinations(“SFAS No. 141-R”),which revised SFAS No. 141,Business Combinations.SFAS No. 141-R is effective for us beginning January 1, 2009. Under SFAS No. 141, organizations utilized the announcement date as the measurement date for the purchase price of the acquired entity. SFAS No. 141-R requires measurement at the date the acquirer obtains control of the acquiree, generally referred to as the acquisition date. SFAS No. 141-R will have a significant impact on the accounting for transaction costs and restructuring costs, as well as the initial recognition of contingent assets and liabilities assumed during a business combination. Under SFAS No. 141-R, adjustments to the acquired entity’s deferred tax assets and uncertain tax position balances occurring outside the measurement period are recorded as a component of the income tax expense, rather than goodwill. We adopted this statement on January 1, 2009. SFAS No. 141-R’s impact on accounting for business combinations is dependent upon acquisitions, if any, made on or after that time.

FSP No. EITF 03-6-1

In June 2008, the FASB issued Staff Position (“FSP”) No. EITF 03-6-1,Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities(“FSP EITF 03-6-1”),which addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in earnings allocation in computing earnings per share under the two-class method as described in SFAS No. 128,Earnings Per Share.Under the guidance in FSP EITF 03-6-1, unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two class method. We adopted

FSP EITF 03-6-1 on January 1, 2009 and, in accordance with the FSP, have retrospectively adjusted prior-period earnings per share data. ~~See Note 4.~~The table below displays the as previously reported and adjusted basic and diluted earnings per share for all prior periods affected by this new pronouncement.

In September 2006, the FASB issued SFAS No. 157,Fair Value Measurements(“SFAS No. 157”),which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (“GAAP”) and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. For financial assets and liabilities, SFAS No. 157 was effective for us beginning January 1, 2008. In February 2008, the FASB issued FASB Staff Position FSP No. FAS 157-1,Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13 and FSP No. FAS 157-2, Effective Date of FASB Statement No. 157.FSP 157-1 amends SFAS No. 157 to remove certain leasing transactions from its scope. FSP 157-2 delayed the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008 for all non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) and was adopted by the Company beginning first quarter 2009. In October 2008, the FASB issued FSP No. FAS 157-3,Determining the Fair Value of a Financial Asset When the Market for That Asset is Not Active,to clarify the application of SFAS 157 in inactive markets for financial assets. FSP 157-3 became effective upon issuance and SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. In April 2009, the FASB issued FSP No. FAS 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly (“FSP 157-4”), to provide additional guidance and expand on the factors that should be considered in estimating fair value when there has been a significant decrease in market activity for a financial asset. FSP 157-4 became effective for interim and annual periods ending after June 15, 2009. The adoption of SFAS No. 157 for both financial and non-financial assets and liabilities did not have ana material effect on the Company’s financial condition or results of operations.

FSP 107-1

In April 2009, the FASB issued FSP No. FAS 107-1 and Accounting Principles Board (APB) 28-1, Interim Disclosures about Fair Value of Financial Instruments (“FSP 107-1”), which requires disclosure about fair value of financial instruments in interim and annual financial statements. We adopted FSP 107-1 in second quarter 2009, and the adoption had no financial impact on the Company’s Condensed Consolidated Financial Statements.

FSP 115-2

In April 2009, the FASB issued FSP FAS No. 115-2 and FAS No. 124-2, Recognition and Presentation of Other-Than-Temporary Impairments (“FSP 115-2”), which provides operational guidance for determining other-than-temporary impairments for debt securities. We adopted FSP 115-2 in second quarter 2009, and the adoption did not have a material effect on the Company’s Condensed Consolidated Financial Statements.

SFAS No. 165

In May 2009, the FASB issued SFAS No. 165,Subsequent Events(“SFAS No. 165”). SFAS No. 165 establishes standards for accounting for and disclosing subsequent events (events which occur after the balance sheet date but before financial statements are issued or are available to be issued). SFAS No. 165 requires an entity to disclose the date subsequent events were evaluated and whether that evaluation took place on the date financial statements were issued or were available to be issued. This standard is effective for interim and annual periods ending after June 15, 2009. The adoption of SFAS No. 165 did not have a material impact on the Company’s financial condition or results of operations.

SFAS No. 168

In June 2009, the FASB issued SFAS No. 168,The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles(“SFAS No. 168”). SFAS No. 168 replaces FASB Statement No. 162,The Hierarchy of Generally Accepted Accounting Principles, and establishes the FASB Accounting Standards Codification^TM (the Codification) as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. SFAS No. 168 is effective for interim and annual periods ending after September 15, 2009. We will begin to use the new Codification when referring to GAAP in our quarterly filing on Form 10-Q for the period ending September 30, 2009. This will not have an impact on the consolidated results of the Company.

2.REPOSITIONING:

On March 30, 2009, we announced a repositioning plan that includes the expansion of the technology development and licensing business, the cessation of further product development of the SlimChip modem technology, and efforts to monetize the SlimChip technology investment through IP licensing and technology sales. In connection with the repositioning, the ~~company~~Company incurred a charge of ~~$37.1~~$37.0 million during first ~~quarter~~half 2009. Of this amount, approximately $30.6 million represents non-cash asset impairments that relate to assets used in the product and product development, including $21.2 million of acquired intangible assets and $9.4 million of property, equipment and other assets. During second quarter 2009, the repositioning charge was reduced by $0.1 million primarily due to a change in estimate for contract termination costs.

In addition, the repositioning resulted in a reduction in force of approximately 100 employees across the ~~company’s~~Company’s three locations, the majority of which were terminated effective April 3, 2009. Approximately ~~$6.5~~$6.4 million of the repositioning charge represents cash obligations associated with severance and contract termination costs. Substantially all of the severance and related costs are scheduled to be paid within twelve months of the balance sheet date.

The following table provides information related to our first ~~quarter~~half 2009 repositioning charge and the related accrued liability for repositioning costs, which is included on our balance sheet within Other accrued expenses (in thousands):

3.INCOME TAXES:

In first ~~quarter~~half 2009, our effective tax rate was approximately ~~33%~~36.4% based on the statutory federal tax rate net of discrete state and ~~local~~foreign taxes. During first ~~quarter~~half 2008, our effective tax rate was ~~35%~~35.5% based on the statutory federal tax rate net of permanent differences.

During first ~~quarter~~half 2009 and 2008, we paid approximately $16.5 million and $15.9 million, respectively, of foreign withholding tax. We established a corresponding deferred tax asset related to foreign tax credits that we expect to utilize to offset future U.S. federal income taxes.

Our future book tax expense may also be affected by charges associated with any share-based tax shortfalls that may occur under SFAS No. 123(R),Share-Based Payment. However, we cannot predict if, when or to what extent this will affect our future tax expense. If, in the course of future tax planning, we identify tax saving opportunities that entail amending prior year returns in order to avail ourselves fully of credits that we previously considered unavailable to us, we will recognize the benefit of the credits in the period in which they are both identified and quantified, thereby reducing the book tax expense in that period.

~~For the three months ended March 31, 2008,~~ options to purchase approximately ~~1.0~~0.5 million shares of common stock were excluded from the computation of diluted earnings per share because the exercise prices of these options were greater than the ~~weighted average~~weighted-average market price of our common stock during this period and, therefore, their effect would have been anti-dilutive.

For the three and six months ended June 30, 2008, options to purchase approximately 0.8 million shares and 0.9 million shares of common stock, respectively, were excluded from the computation of diluted earnings per share because the exercise prices of these options were greater than the weighted-average market price of our common stock during this period and, therefore, their effect would have been anti-dilutive.

5.LITIGATION AND LEGAL PROCEEDINGS:

Nokia Litigation

Nokia USITC Proceeding and Related Delaware District Court and Southern District of New York Proceedings

In August 2007, InterDigital filed a USITC Complaint against Nokia Corporation and Nokia, Inc. (collectively, “Nokia”) alleging that Nokia engaged in an unfair trade practice by selling for importation into the United States, importing into the United States, and selling after importation into the United States, certain 3G mobile handsets and components that infringe two of InterDigital’s patents. In November and December 2007, a third patent and fourth patent, respectively, were added to our Complaint against Nokia. The Complaint seeks an exclusion order barring from entry into the United States infringing 3G mobile handsets and components that are imported by or on behalf of Nokia. Our Complaint also seeks a cease-and-desist order to bar further sales of infringing Nokia products that have already been imported into the United States.

In addition, on the same date as our filing of the USITC action referenced above, we also filed a Complaint in the Delaware District Court alleging that Nokia’s 3G mobile handsets and components infringe the same two InterDigital patents identified in the original USITC Complaint. This Delaware action was stayed on January 10, 2008, pursuant to the mandatory, statutory stay of parallel district court proceedings at the request of a respondent in a USITC investigation. Thus, this Delaware action is stayed until the USITC’s determination in this matter becomes final. The Delaware District Court permitted InterDigital to add to the ~~staid~~stayed Delaware action the third and fourth patents InterDigital asserted against Nokia in the USITC action.

Nokia, joined by Samsung Electronics Co., Ltd. (“Samsung”), moved to consolidate the Nokia USITC proceeding with an investigation we had earlier initiated against Samsung in the USITC. On October 24, 2007, the Honorable Paul J. Luckern, the Administrative Law Judge overseeing the two USITC proceedings against Samsung and Nokia, respectively, issued an Order to consolidate the two pending investigations. Pursuant to the Order, the schedules for both investigations were revised to consolidate proceedings and set a unified evidentiary hearing on April 21-28, 2008, the filing of a single initial determination by Judge Luckern by July 11, 2008, and a target date for the consolidated investigations of November 12, 2008, by which date the USITC would issue its final determination (the “Target Date”).

On December 4, 2007, Nokia moved for an order terminating or, alternatively, staying the USITC investigation as to Nokia, on the ground that Nokia and InterDigital must first arbitrate a dispute as to whether Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation. On January 8, 2008, Judge Luckern issued an order denying Nokia’s motion and holding that Nokia has waived its arbitration defense by instituting and participating in the investigation and other legal proceedings. On February 13, 2008, Nokia filed an action in the U.S. District Court for the Southern District of New York (the “Southern District Action”), seeking to preliminarily enjoin InterDigital from proceeding with the USITC investigation with respect to Nokia, in spite of Judge Luckern’s ruling denying Nokia’s motion to terminate the USITC investigation. Nokia raised in this preliminary injunction action the same arguments it

raised in its motion to terminate the USITC investigation, namely that InterDigital allegedly must first arbitrate its alleged license dispute with Nokia and that Nokia has not waived arbitration of this defense. In the Southern District Action, Nokia also sought to compel InterDigital to arbitrate its alleged license dispute with Nokia and, in the alternative, sought a determination by the District Court that Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation. On March 7, 2008, InterDigital filed a motion to dismiss Nokia’s claim in the alternative that Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation.

On February 8, 2008, Nokia filed a motion for summary determination in the USITC that InterDigital cannot show that a domestic industry exists in the United States as required to obtain relief. Samsung joined this motion. InterDigital opposed this motion. On February 14, 2008, InterDigital filed a motion for summary determination that InterDigital satisfies the domestic industry requirement based on its licensing activities. On February 26, 2008, InterDigital filed a motion for summary determination that it has separately satisfied the so-called “economic prong” for establishing that a domestic industry exists based on InterDigital’s chipset product that practices the asserted patents. Samsung and Nokia opposed these motions. On March 17, 2008, Samsung and Nokia filed a motion to strike any evidence concerning InterDigital’s product and to preclude InterDigital from introducing any such evidence in relation to domestic industry at the evidentiary hearing. On March 26, 2008, the Administrative Law Judge granted InterDigital’s motion for summary determination that it has satisfied the so-called “economic prong” for establishing that a domestic industry exists based on InterDigital’s chipset product that practices the asserted patents and denied Samsung’s motion to strike and preclude introduction of evidence concerning InterDigital’s domestic industry product.

On March 17, 2008, Nokia and Samsung jointly moved for summary determination that U.S. Patent No. 6,693,579, which was asserted against both Samsung and Nokia, is invalid. InterDigital opposed this motion. On April 14, 2008, the Administrative Law Judge denied Nokia’s and Samsung’s joint motion for summary determination that the ‘579 patent is invalid.

On March 20, 2008, the U.S. District Court for the Southern District of New York, ruling from the bench, decided that Nokia is likely to prevail on the issue of whether Nokia’s alleged entitlement to a license is arbitrable. The Court did not consider or rule on whether Nokia is entitled to such a license. As a result, the Court entered a preliminary injunction requiring InterDigital to participate in arbitration of the license issue and requiring InterDigital to cease participation in the USITC proceeding by April 11, 2008, but only with respect to Nokia. The Court further ordered Nokia to post a $500,000 bond by March 28, 2008, which Nokia did. InterDigital promptly filed a request for a stay of the preliminary injunction and for an expedited appeal with the U.S. Court of Appeals for the Federal Circuit, which transferred the appeal to the U.S. Court of Appeals for the Second Circuit. The preliminary injunction became effective on April 11, 2008, and, in accordance with the Court’s order, InterDigital filed a motion with the Administrative Law Judge to stay the USITC proceeding against Nokia pending InterDigital’s appeal of the District Court’s decision or, if that appeal were unsuccessful, pending the Nokia TDD Arbitration (described below). On April 14, 2008, the Administrative Law Judge ordered that the date for the commencement of the evidentiary hearing, originally scheduled for April 21, 2008, be suspended until further notice from the Administrative Law Judge. The Administrative Law Judge did not at that point change the scheduled date of July 11, 2008 for his initial determination in the investigation or the scheduled Target Date of November 12, 2008 for a decision by the USITC. InterDigital’s motion for a stay of the preliminary injunction and for an expedited appeal was

considered by a panel of the Second Circuit on April 15, 2008. On April 16, 2008, the Second Circuit denied the motion for stay but set an expedited briefing schedule for resolving InterDigital’s appeal on the merits of whether the District Court’s order granting the preliminary injunction should be reversed.

On April 17, 2008, InterDigital filed a motion with the USITC to separate the consolidated investigations against Nokia and Samsung in order for the investigation to continue against Samsung pending the expedited appeal or, if the appeal is unsuccessful, pending the Nokia TDD Arbitration. Samsung and Nokia opposed InterDigital’s motion. On May 16, 2008, the Administrative Law Judge deconsolidated the investigations against Samsung and Nokia and set an evidentiary hearing date in the investigation against Samsung (337-TA-601) to begin on July 8, 2008.

On May 20, 2008, the Administrative Law Judge denied without prejudice all pending motions in the consolidated investigation (337-TA-613).

On June 17, 2008, a panel of the U.S. Court of Appeals for the Second Circuit heard oral argument on InterDigital’s appeal from the Order of the U.S. District Court for the Southern District of New York preliminarily enjoining InterDigital from proceeding against Nokia in the consolidated investigation. On July 31, 2008, the Second Circuit reversed the preliminary injunction, finding that Nokia’s litigation conduct resulted in a waiver of any right to arbitrate its license dispute. InterDigital promptly notified the Administrative Law Judge in the Nokia investigation (337-TA-613) of the Second Circuit’s decision. On August 14, 2008, Nokia filed a petition for rehearing and petition for rehearing en banc of the Second Circuit’s decision, and on September 15, 2008, the Second Circuit denied Nokia’s petitions. The mandate from the Second Circuit issued to the Southern District of New York on September 22, 2008. Notwithstanding the Second Circuit’s decision, on October 17, 2008 Nokia filed a request for a status conference with the District Court to establish a procedural schedule for Nokia to pursue a permanent injunction requiring InterDigital to arbitrate Nokia’s alleged license defense, and arguing that the Second Circuit’s decision does not bar such an action. On October 23, 2008, InterDigital filed a response with the District Court asserting that the Second Circuit’s waiver finding was dispositive, and seeking the dismissal of Nokia’s complaint in its entirety. On March 5, 2009, the Court in the Southern District Action granted InterDigital’s request and dismissed all of Nokia’s claims in the Southern District Action, but delayed issuing a final judgment pending a request by InterDigital seeking to collect against the $500,000 preliminary injunction bond posted by Nokia. On April 3, 2009, InterDigital filed a motion to collect against the preliminary injunction

bond, contending that InterDigital was damaged by at least $500,000 as a result of the wrongfully obtained preliminary injunction. Briefing on InterDigital’s motion has been completed, but the Court has not yet ruled on this motion.

On September 24, 2008, InterDigital filed a motion to lift the stay of the Nokia investigation (337-TA-613) based on the issuance of the Second Circuit’s mandate reversing the preliminary injunction granted to Nokia. The Administrative Law Judge granted InterDigital’s motion on September 25, 2008 and lifted the stay. On October 7, 2008, the Administrative Law Judge issued an Order in the Nokia investigation setting the evidentiary hearing for May 26-29, 2009. On October 10, 2008, the Administrative Law Judge issued an Order resetting the Target Date for the USITC’s Final Determination in the Nokia investigation to December 14, 2009, and requiring a final Initial Determination by the Administrative Law Judge to be entered no later than August 14, 2009.

On January 21, 2009, Nokia filed a motion to schedule a claim construction hearing in the USITC proceeding in early February 2009, and on January 29, 2009, InterDigital filed an opposition to the motion for a claim construction hearing. On February 9, 2009, the Administrative Law Judge denied Nokia’s motion for a claim construction hearing.

On February 13, 2009, InterDigital filed a renewed motion for summary determination that InterDigital has satisfied the domestic industry requirement based on its licensing activities, and on February 27, 2009, Nokia filed an opposition to the motion. On March 10, 2009, the Administrative Law Judge granted InterDigital’s motion, finding that InterDigital has established, through its licensing activities, that a domestic industry exists in the United States as required to obtain relief before the USITC. On April 9, 2009, the Commission issued a notice that it would not review the Administrative Law Judge’s Order granting summary determination of a licensing-based domestic industry, thereby adopting the Administrative Law Judge’s decision.

The evidentiary hearing for the USITC investigation with respect to Nokia ~~remains scheduled to begin on~~was held from May 26, ~~2009. The Administrative Law Judge issued an Order on March 24,~~ 2009 ~~indicating the hearing will terminate at noon on May 29, 2009 and continue, if necessary, on the morning only of~~through June 2, 2009. Posthearing briefing for the USITC investigation with respect to Nokia has been completed. A final Initial Determination by the Administrative Law Judge is expected by August 14, 2009, and the Final Determination by the USITC is expected by December 14, 2009.

Nokia TDD Arbitration

On April 1, 2008, Nokia Corporation filed a Request for Arbitration with the International Chamber of Commerce against InterDigital, Inc.~~, IDC~~ and ~~ITC,~~its wholly owned subsidiaries InterDigital Communications, LLC, and InterDigital Technology Corporation, seeking a declaration that Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation pursuant to the parties’ TDD Development Agreement. ~~InterDigital believes that Nokia’s request for declaratory relief in the TDD Arbitration is meritless.~~

On May 9, 2008, InterDigital filed an Answer to Nokia’s Request for Arbitration, requesting,inter alia: (i) that the arbitration be dismissed because the dispute is not arbitrable and, even if arbitrable, Nokia waived its right to arbitration; and, in the alternative, (ii) a declaration that Nokia is not licensed to the patents at issue in the USITC investigation pursuant to the parties’ TDD Development Agreement.

On July 17, 2008, the arbitral tribunal was constituted.

On July 31, 2008, as discussed above, the United States Court of Appeals for the Second Circuit reversed the district court’s grant of an order requiring InterDigital to submit the TDD issue to arbitration, finding that Nokia waived any right to arbitrate the issue. InterDigital ~~believes~~believed that Nokia should not be permitted to continue to pursue this arbitration in light of the Second Circuit’s finding of waiver and ~~has~~ requested that the arbitration be dismissed. Nokia asserted that the Second Circuit’s decision was not a final decision on the issue of waiver, and has contended that Nokia may submit the waiver issue to the arbitral tribunal or, as indicated above, to the District Court on remand. However, as discussed above (see “Nokia USITC Proceeding and Related Delaware District Court and Southern District of New York Proceedings” above), on March 5, 2009, the Court in the Southern District Action issued an order dismissing Nokia’s complaint in its entirety, agreeing with InterDigital that the Second Circuit’s decision on waiver was final. ~~On May 8,~~In light of the above, on June 4, 2009, Nokia informed the Tribunal that Nokia ~~intends to withdraw~~was withdrawing its Request for Arbitration. On June 25, 2009, the International Chamber of Commerce informed the parties that it was closing the file for this arbitration.

Other

We have filed patent applications in the United States and in numerous foreign countries. In the ordinary course of business, we currently are, and expect from ~~time-to-time~~time to time to be, subject to challenges with respect to the validity of our patents and with respect to our patent applications. We intend to continue to defend vigorously the validity of our patents and defend against any such challenges. However, if certain key patents are revoked or patent applications are denied, our patent licensing opportunities could be materially and adversely affected.

We and our licensees, in the normal course of business, might have disagreements as to the rights and obligations of the parties under the applicable patent license agreement. For example, we could have a disagreement with a licensee as to the amount of reported sales of covered products and royalties owed. Our patent license agreements typically provide for arbitration as the mechanism for resolving disputes. Arbitration proceedings can be resolved through an award rendered by an arbitration panel or through private settlement between the parties.

In addition to disputes associated with enforcement and licensing activities regarding our intellectual property, including the litigation and other proceedings described above, we are a party to other disputes and legal actions not related to our intellectual property, but also

arising in the ordinary course of our business. Based upon information presently available to us, we believe that the ultimate outcome of these other disputes and legal actions will not have a material adverse effect on us.

~~Among the types of legal proceedings we encounter in the normal course of business, we are engaged in the following action:~~

~~Federal~~

In May 2007, the Arbitrator in the arbitration proceeding between InterDigital Communications Corporation (now IDC) and ITC (collectively, for purposes of the Federal arbitration described herein, “InterDigital,” “we,” or “our”) and Federal Insurance Company (“Federal”), and relating to a Litigation Expense and Reimbursement Agreement signed in February 2000 by the parties (“Reimbursement Agreement”), refused to award the full amount of Federal’s claim, which was in excess of $33.0 million. The Arbitrator did award Federal approximately $13.0 million, pursuant to a formula set forth in the Reimbursement Agreement, for reimbursement of attorney’s fees and expenses previously paid to or on behalf of InterDigital by Federal, plus approximately $2.0 million in interest. As additional reimbursement of attorney’s fees and expenses, the Arbitrator awarded $5.0 million, without interest, as Federal’s share under the Reimbursement Agreement of “additional value” of the 2003 settlement between InterDigital and Ericsson Inc. Further, the Arbitrator ruled that InterDigital must pay Federal 10% of any additional payments InterDigital may receive as a result of an audit of Sony Ericsson’s sales. In June 2007, we notified Federal that we had received $2.0 million from Sony Ericsson to resolve Sony Ericsson’s payment obligations following an audit. The approximately $13.0 million portion of the Award represents a percentage of the amounts InterDigital has received since March 2003 from Telefonaktiebolaget LM Ericsson and Ericsson Inc. and Sony Ericsson Mobile Communications AB under their respective patent license agreements.

In June 2007, Federal moved to confirm the Award in the United States District Court for the Eastern District of Pennsylvania. Also in June 2007, we filed an opposition to Federal’s motion to confirm the arbitration Award and a cross motion to vacate a portion of the Award, totaling approximately $14.5 million, on the ground that the Arbitrator exceeded the scope of her authority. We also moved the Court to stay confirmation of the Award pending adjudication of our recoupment defense whereby we are seeking to recoup the full amount of the Award based on Federal’s bad faith breach of its contractual and fiduciary duties to us. In July 2007, the Court heard oral arguments on Federal’s motion to confirm the Award, our opposition thereto, and our cross motion to vacate the Award and to stay confirmation pending adjudication of our recoupment defense. On March 24, 2008, the Court: (i) granted Federal’s motion to confirm the arbitration award; and (ii) denied InterDigital’s motion to stay confirmation of the arbitration award pending adjudication of InterDigital’s claim for recoupment based on Federal’s bad faith breach of its duties as InterDigital’s insurer. On April 1, 2008, InterDigital filed a notice of appeal to the United States Court of Appeals for the Third Circuit. In order to stay execution on Federal’s judgment pending appeal, InterDigital deposited $23.0 million with the Clerk of the Court, an amount sufficient to secure Federal’s judgment and anticipated interest until decision by the Court of Appeals. On April 10, 2008, the Court extended Federal’s deadline for seeking costs and fees until after conclusion of the appeal.

On May 6, 2008, the Court of Appeals assigned the matter for mediation in the Court of Appeals mediation program. The mediation program concluded without any settlement. Consequently, InterDigital and Federal have commenced briefing the appeal.

On July 7, 2008, the Company filed its opening brief, seeking reversal of the District Court’s refusal to hear InterDigital’s recoupment claim and remand to the District Court for adjudication of such claim as a set-off to Federal’s arbitration award. Federal’s brief was filed on August 6, 2008. The Company’s reply brief was filed on August 20, 2008. The appeal was submitted to the Court of Appeals on January 8,

~~2009. On January 29, 2009, the Court of Appeals affirmed the District Court’s March 24, 2008 Order. On February 23, 2009, Federal moved to lift the stay of enforcement of Federal’s judgment.~~

The Federal dispute was settled and brought to an end on April 22, 2009, pursuant to a confidential agreement between the parties. In connection with this settlement, approximately $21.1 million of the bond was paid to Federal and the balance of approximately $2.0 million, including interest, was reimbursed to InterDigital. In first quarter 2009, InterDigital recognized $0.6 million in interest income to adjust accrued interest in connection with this settlement.

6.REPURCHASE OF COMMON STOCK:

In October 2007, our Board of Directors authorized a $100.0 million share repurchase program (the “2007 Repurchase Program”). In March 2009, our Board of Directors authorized another $100.0 million share repurchase program (the “2009 Repurchase Program”). The Company may repurchase shares under the programs through open market purchases, pre-arranged trading plans or privately negotiated purchases. During 2008, we completed the 2007 Repurchase Program ~~through the repurchase of 3.8 million shares of common stock for $81.5 million, for~~under which we repurchased a cumulative total of 4.8 million shares totaling $100.0 ~~million. We did not make any share repurchases during~~million, including 1.8 million shares we repurchased for $36.0 million in first ~~quarter 2009. Under~~half 2008. During first half 2009, we repurchased approximately 0.6 million shares for $14.7 million under the 2009 Repurchase ~~Program,~~Program. At June 30, 2009, we ~~repurchased 0.2~~accrued approximately $0.7 million ~~shares of common stock for $5.6 million from April~~associated with our obligation to settle repurchases made late in second quarter 2009.

From July 1, 2009 through ~~May 1, 2009.~~July 27, 2009, we repurchased an additional 0.1 million shares for $4.1 million, to bring the cumulative repurchase totals to 0.7 million shares at a cost of $18.8 million under the 2009 Repurchase Program.

8.INVESTMENTS IN OTHER ENTITIES:

We may make strategic investments in companies that have developed or are developing technologies that are complementary to our ~~patent licensing and technology development strategy.~~business. During 2007, we made a $5.0 million investment for a non-controlling interest in Kineto Wireless (“Kineto”). This investment is recorded on our balance sheet within Other Non-Current Assets. In first quarter 2008, we wrote-down this investment $0.7 million based on a lower valuation of Kineto by its investors. Early in second quarter 2008, we participated in a new round of financing that included several other investors, investing an additional $0.7 million in Kineto. This second investment both maintained our ownership position and preserved certain liquidation preferences. We do not have significant influence over Kineto and are accounting for this investment using the cost method of accounting. Under the cost method, we will not adjust our investment balance when the investee reports profit or loss but will monitor the investment for an other-than-temporary decline in value. When assessing whether an other-than-temporary decline in value has occurred, we will consider such factors as the valuation placed on the investee in subsequent rounds of financing, the performance of the investee relative to its own performance targets and business plan, and the investee’s revenue and cost trends, liquidity and cash position, including its cash burn rate, and updated forecasts.

9.INSURANCE REIMBURSEMENT:

~~During~~In first ~~quarter~~half 2008, we received ~~commitments~~payments from insurance providers of $6.9 million to reimburse us for portions of our defense costs in certain litigation with Nokia. This amount reduced our patent administration and licensing expense in 2008. We did not receive any such reimbursements during first ~~quarter~~half 2009.

10.CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES:

Concentration of Credit Risk and Fair Value of Financial Instruments

Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We place our cash equivalents and short-term investments only in highly rated financial instruments and in United States Government instruments.

Our accounts receivable are derived principally from patent license agreements and technology solutions. At June 30, 2009, two customers represented 82% and 15% of our accounts receivable balance. At December 31, 2008, four customers represented 59%, 17%, 10% and 10% respectively, of our accounts receivable balance. We perform ongoing credit evaluations of our customers who generally include large, multi-national, wireless telecommunications equipment manufacturers. We believe that the carrying value of our financial instruments approximate their fair values.

SFAS No. 157 Fair Value Measurements

Effective January 1, 2008, we adopted the provisions of SFAS No. 157.Fair Value Measurementsthat relate to our financial assets and financial liabilities. SFAS No. 157 establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below:


Item 2.		MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

OVERVIEW

The following discussion should be read in conjunction with the unaudited, condensed consolidated financial statements and notes thereto contained elsewhere in this document, in addition to our 2008 Form 10-K as filed with the SEC on March 2, 2009, other reports filed with the SEC and theStatement Pursuant to the Private Securities Litigation Reform Act of 1995 — Forward-Looking Statementsbelow. Please refer to theGlossary of Termsin our 2008 Form 10-K for a list and detailed description of the various technical, industry and other defined terms that are used in this Quarterly Report on Form ~~10-Q for the quarter ended March 31, 2009.~~10-Q.

Patent Licensing

~~Our~~Patent licensing royalties of $72.7 million in second quarter 2009 posted a 29 percent increase over $56.2 million in second quarter 2008, due to the addition of $25.7 million in fixed-fee amortized royalty revenue from a patent license agreement with Samsung signed in first quarter 2009, ~~results include approximately two and one-half months of~~$2.3 million in royalties for past sales, partially offset by a $10.4 million decrease in per-unit royalty revenue ~~from our recently signed license agreement~~related to industry-wide declines in handset sales for comparable first quarter sales. Despite this overall decline in per-unit royalties, certain licensees with ~~Samsung. This helped push our total recurring revenue~~concentrations in the smartphone market reported increased sales for the quarter over $70.0 million and increased the penetration of our patent licensing program to approximately 50% of the 3G market. We are actively seeking licenses with additional parties to further increase our base of recurring patent license royalties and penetration into the 3G market.reporting period.

Repositioning

We currently estimate that we will incur additional repositioning costs of approximately $1.0 million to $2.0 million in second ~~quarter~~half 2009, but the timing and amount of the additional charge will be dependent upon our process to ~~wind-down~~wind down activities related to our SlimChip product development.

~~We expect that~~Through the reduction in force and the cessation of further product development of the SlimChip modem technology, the repositioning ~~will reduce~~reduced our ~~development~~Development expense for second quarter 2009 by approximately ~~$13.0~~$13.6 million from first quarter 2009.

Litigation and Arbitration

Please see Note 5, “Litigation and Legal Proceedings,” in the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report onForm 10-Q for a full discussion of the following matter and other matters:

Nokia USITC

In August 2007, we filed a complaint against Nokia in the USITC seeking an exclusion order barring Nokia from importing certain unlicensed 3G handsets into the United States. Subsequently, Nokia successfully sought to consolidate the Nokia investigation with an investigation we had earlier initiated against Samsung in the USITC.

Nokia then unsuccessfully sought to terminate or stay the USITC investigation against it on the ground that Nokia and InterDigital must first arbitrate an alleged dispute as to whether Nokia is licensed under the patents asserted by InterDigital against Nokia in the USITC investigation. After that effort failed, Nokia sought and obtained a preliminary injunction in the U.S. District Court for the Southern District of New York preventing us from proceeding in the USITC against Nokia. Shortly after the issuance of the preliminary injunction, the Nokia USITC investigation was stayed, and the Nokia and Samsung USITC investigations were de-consolidated, which permitted the Samsung USITC investigation to move forward.

In July 2008, the Second Circuit reversed the preliminary injunction obtained by Nokia. In September 2008, the Administrative Law Judge lifted the stay in the Nokia USITC ~~investigation, and thereafter issued the following schedule for the investigation:~~


•	~~Evidentiary Hearing~~	~~May 26 — 29 and June 2, 2009~~
•	~~Initial Determination by Administrative Law Judge~~	~~No later than August 14, 2009~~
•	~~Final Determination by USITC~~	~~December 14, 2009~~

investigation. In March 2009, the U.S. District Court for the Southern District of New York dismissed Nokia’s claims relating to its alleged license dispute.

When comparing ~~first~~second quarter 2009 financial results against other periods, the following item should be taken into consideration:

•

~~Our first quarter 2009 operating expense included a $37.1 million repositioning charge in connection with our decision to cease further product development of our SlimChip~~^(™) ~~HSPA technology.~~

Our second quarter 2009 revenue included $2.3 million of revenue related to the resolution of an audit of one of our licensees.

When comparing second quarter 2008 financial results against other periods, the following item should be taken into consideration:

Our second quarter 2008 revenue included $0.3 million related to past infringement and $1.3 million of one-time, incremental revenue associated with one of our licensees transitioning from per-unit royalties to a mix of per-unit and fixed-fee royalties.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our significant accounting policies are described in Note 1 of theNotes to Consolidated Financial Statementsincluded in our 2008 Form 10-K. A discussion of our critical accounting policies, and the estimates related to them, are included inManagement’s Discussion and Analysis of Financial Condition and Results of Operationsin our 2008 Form 10-K. There have been no material changes in our existing critical accounting policies from the disclosures included in our 2008 Form 10-K.

~~NEW ACCOUNTING PRONOUNCEMENTS~~

~~SFAS No. 141-R~~

~~In December 2007, the Financial Accounting Standards Board (“FASB”) issued Statement~~ Refer to Note 1, Basis of ~~Financial Accounting Standard (“SFAS”) No. 141-R,~~~~Business Combinations,~~~~which revised SFAS No. 141,~~~~Business Combinations.~~~~SFAS No. 141-R is effective~~Presentation of this Form 10-Q for us beginning January 1, 2009. Under SFAS No. 141, organizations utilized the announcement date as the measurement date for the purchase price of the acquired entity. SFAS No. 141-R requires measurement at the date the acquirer obtains control of the acquiree, generally referredupdates related to ~~as the acquisition date. SFAS No. 141-R will have a significant impact on the~~new accounting for transaction costs and restructuring costs, as well as the initial recognition of contingent assets and liabilities assumed during a business combination. Under SFAS No. 141-R, adjustments to the acquired entity’s deferred tax assets and uncertain tax position balances occurring outside the measurement period are recorded as a component of the income tax expense, rather than goodwill. We adopted this statement on January 1, 2009. SFAS No. 141-R’s impact on accounting for business combinations is dependent upon acquisitions, if any, made on or after that time.pronouncements.

~~In September 2006, FASB issued SFAS No. 157,~~~~Fair Value Measurements,~~which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. For financial assets and liabilities, SFAS No. 157 was effective for us beginning January 1, 2008. In February 2008, the FASB issued FASB Staff Position FSP No. FAS 157-1,Application of FASB Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value Measurements for Purposes of Lease Classification or Measurement under Statement 13 and FSP No. FAS 157-2, Effective Date of FASB Statement No. 157.FSP 157-1 amends SFAS No. 157 to remove certain leasing transactions from its scope. FSP 157-2 delayed the effective date of SFAS No. 157 to fiscal years beginning after November 15, 2008 for all non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) and was adopted by the Company beginning first quarter 2009. In October 2008, the FASB issued FSP No. 157-3,~~Determining the Fair Value of a Financial Asset When the Market for That Asset is Not Active,~~to clarify the application of SFAS 157 in inactive markets for financial assets. FSP 157-3 became effective upon issuance and SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. The adoption of SFAS No. 157 for both financial and non-financial assets and liabilities did not have an effect on the Company’s financial condition or results of operations.

The positive operating cash flow in first ~~quarter~~half 2009 arose principally from receipts of approximately ~~$120.8~~$201.5 million primarily associated with 3G related ~~to 2G and 3G~~ patent ~~licensing~~license agreements. These receipts included the first of four ~~payments~~installments of $100.0 million from Samsung under our January 2009 license agreement and ~~current royalty payments of $7.4~~$41.2 million under a new $77.0 million prepayment commitment from ~~Sharp Corporation of Japan (Sharp).~~an existing licensee, with the remainder received early in third quarter 2009. We also received fixed ~~and current~~ royalty payments of ~~$13.4~~$21.4 million and per-unit royalty payments of $38.9 million from other existing licensees and cash receipts from our technology solutions totaling ~~$7.1~~$8.8 million, primarily related to royalties associated with our SlimChip modem IP. These receipts were partially offset by cash operating expenses (operating expenses less depreciation of fixed assets, amortization of intangible assets, non-cash repositioning charges and non-cash compensation) of ~~$42.6~~$70.4 million, a cash ~~payment~~payments for foreign source withholding taxes of $16.5 million, ~~related to Samsung~~ cash ~~receipt~~payments for an estimated federal tax payment of $4.0 million and changes in working capital during first ~~quarter~~half 2009.

The positive operating cash flow in first ~~quarter~~half 2008 arose principally from receipts of approximately ~~$147.4~~$230.0 million primarily associated with 3G related ~~to 2G and 3G~~ patent ~~licensing~~license agreements. These receipts included the third of three $95.0 million payments from LG, ~~$10.4~~a new prepayment of $29.6 million from an existing licensee and current royalty payments of $20.7 million from Sharp Corporation of Japan ~~(Sharp)~~(“Sharp”), ~~$5.6~~$13.4 million from NEC Corporation of Japan (“NEC”) and ~~$36.4~~$6.8 million from Panasonic Mobile Communications Co., Ltd. based on the royalty reports they submitted during the period. We also received fixed and current royalty payments of $64.5 million from other existing ~~licensees.~~licensees and cash receipts from our technology solutions totaling $3.0 million, primarily related to royalties associated with our SlimChip modem IP. These receipts were partially offset by cash operating expenses (operating expenses less depreciation of fixed assets, amortization of intangible assets and non-cash compensation) of ~~$36.7~~$79.4 million, cash payments for foreign source withholding taxes of $15.7 million, payment of $23.0 million to post a bond for the Federal Insurance Company arbitration award and changes in working capital during first ~~quarter~~half 2008.

Working capital

We believe that working capital, adjusted to exclude cash, cash equivalents, short-term investments, current maturities of debt and current deferred revenue provides additional information about assets and liabilities that may affect our near-term liquidity. Our adjusted working capital, a non-GAAP financial measure, reconciles to working capital, the most directly comparable GAAP financial measure, as follows (in thousands):


	March 31, 2009			December 31, 2008			June 30, 2009			December 31, 2008

Adjusted working capital	$	248,778		$	53,078		$	268,953		$	53,078

Other

Our combined short-term and long-term deferred revenue balance at ~~March 31,~~June 30, 2009 was approximately ~~$506.9~~$533.7 million, an increase of ~~$247.2~~$274.0 million from December 31, 2008. We have no material obligations associated with such deferred revenue. In first ~~quarter~~half 2009, we recorded gross increases in deferred revenue of ~~$300.0~~$385.0 million primarily related to the first three of four $100.0 million payments under the Samsung patent license agreement signed in January 2009. The gross increases in deferred revenue were partially offset by first half 2009 deferred revenue recognition of ~~$42.1~~$88.9 million related to the amortization of fixed-fee royalty payments, ~~$10.7~~$22.1 million related to per-unit exhaustion of prepaid royalties (based upon royalty reports provided by our licensees) and the recognition of deferred revenue related to technology solutions agreements.

Over the next twelve months, based on current patent license agreements, we expect the amortization of fixed-fee royalty payments ~~will~~to reduce the ~~March 31,~~June 30, 2009 deferred revenue balance of ~~$506.9~~$533.7 million by ~~$177.7~~$177.3 million. Additional reductions to deferred revenue will be dependent upon the level of per-unit royalties our licensees report against prepaid balances.

At ~~March 31,~~June 30, 2009 and December 31, 2008, we had approximately ~~2.8~~2.3 million and 2.9 million options outstanding, respectively, that had exercise prices less than the fair market value of our stock at each balance sheet date. These options would generate ~~$37.1~~$29.4 million and $38.9 million of ~~respective~~ cash proceeds to the Company if they were fully exercised.

Credit Facility

In light of our current financial position and in connection with the reduction of recurring operating expenses expected to result from our repositioning plan, we elected to terminate our $60.0 million unsecured revolving credit facility on April 2, 2009.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements as defined by Item 303(a)(4) of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended.

RESULTS OF OPERATIONS

~~First~~Second Quarter 2009 Compared to ~~First~~Second Quarter 2008

Revenues

The following table compares ~~first~~second quarter 2009 revenues to revenues in the comparable period from the prior year (in millions):


					Second		Second
	For the Three Months Ended March 31,				Quarter		Quarter
	2009		2008		2009		2008
Per-unit royalty revenue	$	27.2	$	32.6	$	23.7	$	34.1
Fixed-fee amortized royalty revenue		42.1		20.7		46.7		21.8

Recurring patent licensing royalties		69.3		53.3		70.4		55.9
Past infringement and other non-recurring royalties		—		0.5		2.3		0.3

Total patent licensing royalties		69.3		53.8		72.7		56.2
Technology solutions revenue		1.3		2.2		2.2		2.5

Total revenue	$	70.6	$	56.0	$	74.9	$	58.7

In second quarter 2009, 53% of our total revenue of $74.9 million was attributable to companies that individually accounted for 10% or more of our total revenue, Samsung (34%) and LG (19%). In second quarter 2008, 55% of our total revenue of $58.7 million was attributable to companies that individually accounted for 10% or more of our total revenue, LG (24%), Sharp (18%) and NEC (13%).

Operating Expenses

Operating expenses decreased 32% to $34.7 million in second quarter 2009 from $50.9 million in second quarter 2008. The $16.2 million decrease was primarily due to the following net changes in expenses (in millions):

(Decrease)/
Increase
Patent litigation and arbitration $ (7.0 )
Personnel related costs (2.9 )
Depreciation and amortization (2.2 )
Consulting services (2.0 )
Reserve for uncollectable accounts (1.0 )
Engineering software and equipment maintenance (0.9 )
Travel expenses (0.3 )
Other (0.9 )
Share-based compensation 1.0

Total decrease in operating expenses $ (16.2 )

Patent litigation and arbitration decreased primarily due to the resolution of our various disputes with Samsung and the third quarter 2008 resolution of the Nokia U.K. disputes. The decrease in personnel-related costs, depreciation and amortization, consulting services, engineering software and equipment maintenance, and travel expenses were primarily due to the repositioning announced on March 30, 2009. The decrease in the reserve for uncollectable accounts was related to our partial collection of an overdue account receivable associated with our SlimChip modem IP. The related customer has agreed to a new payment schedule and we may further reduce this reserve in future periods as the related payments are collected. The above-noted decreases in operating expenses were partially offset by an increase in share-based compensation resulting from the structure of our Long-Term Compensation Program (“LTCP”), which included overlapping restricted stock unit award (“RSU”) cycles in 2009.

The following table summarizes the change in operating expenses by category (in millions):

Second Second
Quarter Quarter
2009 2008 Increase / (Decrease)
Selling, general and administrative $ 6.0 $ 7.2 $ (1.2 ) (17% )
Patent administration and licensing 15.6 21.5 (5.9 ) (27% )
Development 13.2 22.2 (9.0 ) (41% )
Repositioning (0.1 ) — (0.1 ) 0%

Total operating expenses $ 34.7 $ 50.9 $ (16.2 ) (32% )

Selling, General and Administrative Expense:The decrease in selling, general and administrative expense in second quarter 2009 was primarily due to the above-noted reduction in the reserve for uncollectable accounts and a decrease in personnel-related costs due to the repositioning announced on March 30, 2009.

Patent Administration and Licensing Expense:The decrease in patent administration and licensing expense primarily resulted from the above-noted decrease in patent litigation and arbitration ($7.0 million), which was partially offset by increases in consulting services ($0.7 million) and other personnel-related costs ($0.4 million).

Development Expense:The decrease in development expense was primarily due to the above-noted repositioning announced on March 30, 2009.

Repositioning Expense:On March 30, 2009, we announced a repositioning plan under which we (i) have begun to expand our technology development and licensing business and (ii) ceased further product development of our SlimChip HSPA technology and have sought to monetize the product investment through technology licensing. During second quarter 2009, the repositioning charge was reduced by $0.1 million primarily due to a change in estimate for contract termination costs.

Interest and Investment Income, Net

Net interest and investment income for second quarter 2009 totaled $0.6 million, a decrease of $0.6 million from second quarter 2008. The decrease was primarily due to lower rates of return on lower average investment balances in second quarter 2009 as compared to second quarter 2008.

First Half 2009 Compared to First Half 2008

Revenues

The following table compares first ~~quarter~~half 2009 revenues to revenues in the comparable period from the prior year (in millions):

First Half First Half
2009 2008
Per-unit royalty revenue $ 50.9 $ 66.8
Fixed-fee amortized royalty revenue 88.9 42.5

Recurring patent licensing royalties 139.8 109.3
Past infringement and other non-recurring royalties 2.3 0.8

Total patent licensing royalties 142.1 110.1
Technology solutions revenue 3.4 4.6

Total revenue $ 145.5 $ 114.7

Revenues of $145.5 million in first half 2009 grew $30.8 million, or 27 percent, compared to $114.7 million in first half 2008. Patent licensing royalties were $142.1 million in first half 2009, up from $110.1 million in first half 2008. The increase in patent licensing royalties was primarily related to a $46.4 million increase in fixed-fee amortized royalty revenue driven by the company’s patent license agreement with Samsung. This increase was partially offset by a $15.9 million decrease in per-unit royalty revenue relating to an overall decrease in industry handset sales.

Technology solution revenue decreased in first half 2009 to $3.4 million from $4.6 million in first half 2008. The decrease is primarily attributable to engineering service fees earned in first half 2008 associated with our SlimChip modem IP, which did not recur in first ~~quarter~~half 2009. This decrease was partially offset by an increase in royalties earned on our SlimChip modem IP.

In first ~~quarter~~half 2009, ~~61%~~52% of our total revenue of ~~$70.6~~$145.5 million was attributable to companies that individually accounted for 10% or more of ~~this amount, and included~~our total revenue, Samsung ~~(30%), LG (20%~~(32%) and ~~Sharp (11%~~LG (20%). In first ~~quarter~~half 2008, 55% of our total revenue of ~~$56.0~~$114.7 million, was attributable to companies that individually accounted for 10% or more of ~~this amount, and included~~our total revenue, LG ~~(26%~~(25%), Sharp ~~(19%~~(18%) and NEC ~~(10%~~(12%).

Operating Expenses

Excluding a ~~$37.1~~$37.0 million repositioning charge in first ~~quarter~~half 2009, operating expenses ~~increased 5%~~decreased 15% to ~~$47.2~~$82.0 million in first ~~quarter~~half 2009 from ~~$45.1~~$96.0 million in first ~~quarter~~half 2008. The ~~$2.1~~$14.0 million ~~increase~~decrease was primarily due to the following net changes in expenses (in millions):

~~In first~~ Patent litigation and arbitration decreased primarily due to the resolution of our various disputes with Samsung and the third quarter 2008 resolution of the Nokia U.K. disputes. The decrease in personnel-related costs, depreciation and amortization, consulting services, engineering software and equipment maintenance, and travel expenses were primarily due to the repositioning announced on March 30, 2009. The decrease in the reserve for uncollectable accounts was related to our partial collection of an overdue account receivable associated with our SlimChip modem IP. The related customer has agreed to a new payment schedule and we may further reduce this reserve in future periods as the related payments are collected. First half 2008 operating expenses were ~~partly offset by~~reduced due to the inclusion of a $6.9 million insurance reimbursement to reimburse us for a portion of our defense costs in certain litigation with Nokia. Consulting services increased from first quarter 2008 to first quarter 2009 due to our continued precertification and interoperability testing of our SlimChip product family and reference platform development and continued customer evaluations and testing. The increase in share-based compensation and the decrease in long-term cash incentives were both primarily due to the structure of our LTCP, which resulted in overlapping RSU cycles in 2009 and overlapping performance-based cash incentive cycles in 2008. Patent amortization increased due to heightened levels of internal inventive activity in recent years, resulting in the expansion of our patent portfolio. Other depreciation and amortization increased primarily due to acquisitions of technology licenses over the last two years associated with our SlimChip product family. In 2008, we recognized a credit of $1.2 million ~~associated with~~related to the reduction of a previously established accrual associated with our contingent obligation to reimburse Nokia for a portion of its attorney’s fees associated with the ~~recently~~ resolved UKU.K. matters. ~~Patent litigation and arbitration decreased primarily~~Consulting services increased due to ~~the resolution~~first quarter interoperability testing of our SlimChip product family against various ~~disputes with Samsung~~2G/3G network vendors’ equipment, precertification efforts on our SlimChip modem chipset and ~~the resolution of the Nokia UK disputes.~~reference platforms and customer evaluations and testing.

Interest and Investment Income, Net

Net interest and investment income for first ~~quarter~~half 2009 totaled ~~$0.8~~$1.5 million, ~~an increase~~a decrease of ~~$0.4~~$0.2 million infrom first ~~quarter~~half 2008, which included a $0.7 million investment write-down. The ~~increase included~~decrease is primarily related to lower rates of return on lower average investment balances, which was partially offset by a first half 2009 $0.6 million of interest income related to our 2009 settlement of litigation with Federal ~~and was partly offset by lower rates of return in first quarter 2009 as compared to 2008.~~Insurance Company.

Expected Trends

InOur second quarter 2009 Development expenses were slightly lower than expected, reflecting the positive impact of a Canadian research and development credit and lower than expected consulting services as we transitioned our full development efforts to our core business. Our selling, general and administrative expenses also benefited from a $1.0 million credit associated with the reversal of an allowance for an uncollectible receivable. We don’t expect these items to ~~report recurring revenues from existing agreements~~recur in ~~the range of $72.0 million to $75.0 million, an increase of $1.4 million to $4.4 million over first~~third quarter 2009. ~~The expected increase over first~~As is our practice, we will provide an update on our expectation for third quarter 2009 ~~levels reflects~~revenue after we receive and review the recognition of a full quarter of revenue under our new patent license agreement with Samsung and an expected 60 percent to 80 percent increase in our technology solutions revenue resulting from increased royalties from our SlimChip IP, offset by a decrease in per-unit royalties from existing licensees in the range of 5 percent to 10 percent. This range does not include any potential impact from new agreements that might be signed during second quarter 2009 or additional royalties identified in regularly conducted audits.applicable royalty reports.
