Organization, Consolidation and Presentation of Financial Statements [Abstract]
1. Organization and Business1. Organization and Business Organization Mosaic ImmunoEngineering Inc. (the “Company,”
“combined company,” “Mosaic,” “we,” “us,” or “our”), formerly known as Patriot
Scientific Corporation, is a corporation organized under Delaware law on March 24, 1992. We are a preclinical, development-stage
biotechnology company focused on developing and eventually commercializing our proprietary technology designed to activate the innate
immune system to treat and prevent cancer and infectious diseases. Our lead product candidate, MIE-101, is based on a naturally
occurring plant virus that is non-infectious in animals and humans but has been shown to act as strong adjuvant that activates multiple
Toll-like receptors (“TLRs”) through its natural immune recognition. When injected into a tumor, MIE-101 naturally triggers
the body’s innate immune system, thereby altering the tumor microenvironment and directing activated anti-tumor T cells to attack
both the injected tumor as well as other tumors throughout the body. Our goal is to advance MIE-101 into human and veterinary studies
in 2022 if sufficient funding becomes available. The Company has two wholly owned subsidiaries:
Mosaic ImmunoEngineering Development Company (formerly referred to as Private Mosaic in connection with the Reverse Merger), a corporation
organized under Delaware law on March 30, 2020 (date of inception) and Patriot Data Solutions Group, Inc., an inactive subsidiary
of PTSC. Patriot Data Solutions Group (formerly known as Crossflo Systems, Inc.) was acquired in September 2008 and was previously engaged
in data-sharing services and products primarily in the public safety and government sector. During April 2012, PTSC sold substantially
all of the assets in Patriot Data Solutions Group. On August 21, 2020, we completed a reverse merger
transaction pursuant to a stock purchase agreement by and between PTSC (now known as Mosaic ImmunoEngineering Inc.) and Private Mosaic
as further described below. Stock Purchase Agreement On August 19, 2020, Patriot Scientific Corporation
(now known as Mosaic ImmunoEngineering Inc.) and Private Mosaic entered into a stock purchase agreement (“Stock Purchase Agreement”),
whereby one of the wholly owned subsidiaries of Patriot Scientific Corporation merged with and into Private Mosaic, with Private Mosaic
surviving as a wholly owned subsidiary of Patriot Scientific Corporation (the “Reverse Merger”) (see Note 2). The transaction
closed on August 21, 2020 (“Closing Date”) in accordance with the terms of the Stock Purchase Agreement. On the Closing Date, Patriot Scientific Corporation
acquired 100% of the issued and outstanding common stock of Private Mosaic, representing 630,000 70,000 630,000 70,000 10.194106 11.46837 Private Mosaic was determined to be the accounting
acquirer based upon the terms of the Stock Purchase Agreement and other factors including: (i) Private Mosaic stockholders owned
90% of the combined organization immediately following the Closing Date, (ii) Private Mosaic directors held a majority of board seats
in the combined organization and (iii) Private Mosaic management held all key positions in the management of the combined company. Reverse Stock Split On October 21, 2020 and October 22, 2020, our
Board of Directors and majority shareholders, respectively, approved the Reverse Stock Split of one (1) share of our common stock for
every 500 shares of our common stock (“ 1-for-500 In addition, on June 10, 2021 and June 14, 2021,
our Board of Directors and majority shareholders, respectively, approved a discretionary reverse stock split whereby our Board of Directors
have broad authority to implement a future reverse stock split at a ratio ranging from 1-for-2 to 1-for-4 at any time on or before June
25, 2022 in order to meet the initial listing bid price requirement and other listing regulations of the Nasdaq Stock Market or other
national exchanges. The Board believes that listing our common stock on a national exchange will increase the liquidity of our common
stock by providing us with a market for our common stock that is more accessible than if our common stock were to continue to trade on
the OTCQB or on the “pink sheets” maintained by the OTC Markets Group, Inc. If the Board of Directors believes that a discretionary
reverse stock split is in the best interests of the Company and its shareholders, it will consider certain factors in selecting the specific
reverse stock split ratio, including prevailing market conditions, the trading price of our common stock and the steps that we will need
to take in order to meet the initial listing bid price requirement and other listing regulations of the Nasdaq Stock Market or other national
exchanges. We currently do not expect to list our securities on the Nasdaq Stock Market or other national exchange until after we have
filed our Annual Report on Form 10-K for the year ending December 31, 2021. Liquidity and Management’s Plans The accompanying consolidated financial statements
have been prepared assuming the Company will continue as a going concern. At June 30, 2021, the Company had cash and cash equivalents
of $ 582,304 There are a number of uncertainties associated
with our ability to raise additional capital and we have no current arrangements with respect to any additional financing. In addition,
the continuation of disruptions caused by COVID-19 may cause investors to slow down or delay their decision to deploy capital based on
volatile market conditions which will adversely impact our ability to fund future operations. Consequently, there can be no assurance
that any additional financing on commercially reasonable terms, or at all, will be available when needed. The inability to obtain additional
capital will delay our ability to conduct our business operations. Any additional equity financing may involve substantial dilution to
our then existing stockholders. The above matters raise substantial doubt regarding our ability to continue as a going concern.

Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated
financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly
reports on Form 10-Q and do not include all of the information and footnotes required by accounting principles generally accepted in the
United States of America. All intercompany accounts and transactions have been eliminated. In conjunction with the Reverse Merger, Private
Mosaic’s historical results of operations replaced PTSC’s historical results of operations for all periods prior to the Reverse
Merger and, for all periods following the Reverse Merger, the results of operations of the combined company are included in the Company’s
unaudited condensed consolidated financial statements. Since Private Mosaic was incorporated on March 30, 2020, prior year financial information
covers the period March 30, 2020 (date of inception) to June 30, 2020. In addition, operating results for the three months ended June
30, 2021 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2021. The accompanying unaudited condensed consolidated
financial statements have been prepared assuming the Company will continue as a going concern. In the opinion of management, the interim
condensed consolidated financial statements reflect all adjustments of a normal recurring nature necessary for a fair presentation of
the results for the interim period presented. Segment Reporting The Company manages its operations as a single
operating segment for the purposes of assessing performance and making operating decisions. No revenue has been generated since inception,
and all tangible assets are held in the United States. Reverse Merger On August 21, 2020, Private Mosaic completed
a Reverse Merger with PTSC pursuant to which Private Mosaic merged into PTSC (see Note 1). Due to the nominal assets and limited operations
of PTSC prior to the Reverse Merger, the transaction was treated as a reverse acquisition under the provision of Financial Accounting
Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 whereby Private Mosaic became the
accounting acquirer (legal acquiree) and PTSC was treated as the accounting acquiree (legal acquirer). As the transaction was treated
as a reverse asset acquisition, no intangibles, including goodwill, were recognized. The net tangible assets acquired and liabilities
assumed totaled $374,435 which were acquired by Private Mosaic in connection with the transaction and were recorded at their estimated
acquisition date fair values as of the Closing Date, as follows:
Schedule of assets acquired and liabilities assumed
Cash and cash equivalents $ 427,971
Restricted cash and cash equivalents 177,244
Refundable income taxes 26,078
Prepaid expenses and other current assets 10,402
Investment in affiliated company 32,739
Accounts payable, accrued expenses and other (299,999 )
Net assets acquired $ 374,435 Cash and Cash Equivalents We consider all highly liquid investments acquired
with a maturity of three months or less from the purchase date to be cash equivalents. Investment in Affiliated Company We had a 50 4) Financial Instruments and Concentrations of
Credit Risk Financial instruments that potentially subject
us to concentrations of credit risk consist principally of cash and cash equivalents. We invest our cash and cash equivalents primarily
in money market funds. Cash and cash equivalents are maintained with high quality financial institutions, which are regularly monitored
by management. At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit
Insurance Corporation and the Securities Investor Protection Corporation. We perform ongoing evaluations of these financial institutions
to limit our concentration of risk exposure. Fair Value of Financial Instruments Our financial instruments consist principally
of cash and cash equivalents, accounts payable, accrued payable to founders, derivative liability, accrued expenses and other, and convertible
notes. The carrying value of these financial instruments, except for the derivative liability and convertible notes, approximates fair
value because of the immediate or short-term maturity of the instruments. We record the derivative liability at fair value (see Note 3).
The convertible notes are initially recorded at their amortized cost and are being accreted to their redemption value over the estimated
conversion period using the effective interest method (see Note 7). Use of Estimates The preparation of consolidated financial statements
in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during
the reporting period. Significant estimates in these unaudited condensed consolidated financial statements include those related to the
fair value of the anti-dilution issuance rights liability (derivative liability), the timing of conversion of the convertible notes, the
provision or benefit for income taxes and the corresponding valuation allowance on deferred tax assets. In addition, management’s
assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash
inflows and outflows. On an ongoing basis, the Company evaluates its estimates, judgments, and methodologies. The Company bases its estimates
on historical experience and on various other assumptions believed to be reasonable. Due to the inherent uncertainty involved in making
such accounting estimates and assumptions, the actual financial statement results could differ materially from such accounting estimates
and assumptions. Convertible Notes The Company follows ASC 480-10, “Distinguishing
Liabilities from Equity” in its evaluation of the accounting for share-settled debt. ASC 480-10-25-14 requires liability accounting
for certain financial instruments, including shares that embody an unconditional obligation to transfer a variable number of shares, provided
that the monetary value of the obligation is based solely or predominantly on one of the following three characteristics:
a) A fixed monetary amount known at inception;
b) Variations in something other than the fair value of the issuer’s equity shares; or
c) Variations in the fair value of the issuer’s equity shares, but the monetary value to the counterparty
moves in the opposite direction as the value of the issuer’s shares Moreover, equity classification was not an appropriate
classification for the convertible notes because the underlying terms of the convertible notes do not expose the investors to risks and
rewards similar to those of an owner and, therefore, do not create a shareholder relationship. Pursuant to ASC 835-30, the convertible
notes were initially recorded at their amortized cost and are being accreted to their redemption value over the estimated conversion period
using the effective interest method (see Note 7). Assessment of Contingent Liabilities We may be involved in various legal matters, disputes,
and patent infringement claims which arise in the ordinary course of our business. We accrue for any estimated losses at the time when
we can make a reliable estimate of such loss and it is probable that it has been incurred. By their very nature, contingencies are difficult
to estimate. We continually evaluate information related to all contingencies to determine that the basis on which we have recorded our
estimated exposure is appropriate. Share-Based Compensation We account for restricted stock units (“RSUs”)
and other share-based awards granted under our equity compensation plan in accordance with the authoritative guidance for share-based
compensation. The fair value of RSUs is measured at the grant date based on the closing market price of our common stock on the date of
grant and is recognized as expense on a straight-line basis over the period of vesting. Forfeitures are recognized as a reduction of share-based
compensation expense as they occur. At June 30, 2021, there were no outstanding share-based awards with market or performance conditions. In addition, we periodically grant RSUs to non-employee
consultants, which we account for in accordance with the authoritative guidance for share-based compensation. The cost of non-employee
services received in exchange for share-based awards are measured based on either the fair value of the consideration received or the
fair value of the share-based award issued, whichever is more reliably measurable. Basic and Diluted Income (Loss) Per Common
Share Basic income (loss) per common share is computed
by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period.
Diluted earnings per common share is computed by dividing our net income (loss) available to common stockholders by the sum of the weighted
average number of common shares outstanding during the period, plus the potential dilutive effects of unvested RSUs and shares of common
stock expected to be issued under our Series A Preferred and Series B Preferred outstanding during the period. The potential dilutive effect of unvested RSUs
outstanding during the period are calculated in accordance with the treasury stock method, but are excluded if their effect is anti-dilutive.
The potential dilutive effect of our Series B Preferred outstanding during the period is calculated using the if-converted method assuming
the conversion of Series B Preferred as of the earliest period reported or at the date of issuance, if later, but are excluded if their
effect is anti-dilutive. The following table presents the securities excluded
from the calculation of diluted net income (loss) per share for the three and six months ended June 30, 2021 and the three months ended
June 30, 2020 and period March 30, 2020 (date of inception) to June 30, 2020, as the effect of their inclusion would have been anti-dilutive
during periods of net loss:
Schedule of anti-dilutive shares
Three months ended June 30, 2021 Three months ended June 30, 2020 Six months ended June 30, 2021 March 30, 2020 (1) to June 30, 2020
Series B Preferred 802,786 – 802,786 –
Unvested RSUs 423,166 – 379,267 –
Total 1,225,952 – 1,182,053 – Moreover, in connection with an acquisition of
Crossflo by PTSC (see Note 1), 5,690 Recently Adopted Accounting Standards In December 2019, the Financial Accounting Standards
Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying
the Accounting for Income Taxes” (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain
exceptions and improving consistent application in certain areas of Topic 740. ASU 2019-12 is effective for fiscal years, and interim
periods within those years, beginning after December 15, 2020, however, early adoption is permitted. The Company adopted ASU 2018-13 effective
January 1, 2021. Implementation of this guidance did not have a material impact on the Company’s unaudited condensed consolidated
financial statements.

3. Fair Value of Financial Instruments3. Fair
Value of Financial Instruments The Company’s financial instruments consist
of money market funds as well as an anti-dilution issuance rights liability pursuant to the License Option Agreement with Case Western
Reserve University (“CWRU”) (see Note 6). The anti-dilution issuance rights meet the definition of a derivative under FASB’s
ASC Topic 815 and the liability is carried at fair value. Under this authoritative guidance, we are required
to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We determine fair value
based on quoted prices when available or through the use of alternative approaches, such as discounting the expected cash flows using
market interest rates commensurate with the credit quality and duration of the investment or valuations by third-party professionals.
The three levels of inputs that we may use to measure fair value are: Level 1: Unadjusted quoted prices in
active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that
are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability;
and Level 3: Prices or valuation techniques
that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following tables set forth the fair value
of the Company’s financial assets and liabilities by level within the fair value hierarchy as of June 30, 2021 and December 31,
2020:

of Designation, the Series B Preferred includes certain anti-dilution issuance rights, whereby the holder will continue to maintain equity
ownership equal to 10% of the fully diluted shares of common stock outstanding, calculated on an as converted basis, including all other
convertible securities outstanding and reserved for issuance (and excluding stock options issued and outstanding and reserved for issuance
under a Board approved employee stock option plan reserving for issuance no more than ten percent (10%) of the outstanding common stock
of the Company) until the Company raises approximately $626,000 from the sale of common or preferred stock, or a combination thereof (see
Note 6). To determine the estimated fair value of the anti-dilution
issuance rights liability, the Company used a Monte Carlo simulation methodology, which models the future movement of stock prices based
on several key variables. The estimated fair value of the anti-dilution issuance rights at the date of issuance on August 21, 2020 (at
inception), December 31, 2020, and June 30, 2021, was $83,500, $83,500 and $104,300, respectively. We initially recorded the fair value
as a derivative liability with a corresponding charge to research and development expense and we will mark-to-market at each reporting
period, with changes in fair value recognized in other income (expense) in the consolidated statement of operations at each period-end
while this derivative instrument is outstanding. The primary inputs used in valuing the anti-dilution
issuance rights liability at inception, December 31, 2020 and June 30, 2021, were as follows:

Option Agreement On July 1, 2020, we signed a Material Transfer,
Evaluation, and Exclusive Option Agreement (“License Option Agreement”) with CWRU, granting the Company the exclusive right
to license certain technology covering immunostimulatory nanotechnology-based therapeutics and vaccines to treat and prevent cancer and
infectious diseases in humans and for veterinary use. Under the License Option Agreement, CWRU granted the Company the exclusive option
for a period of two (2) years to negotiate and enter into a license agreement with CWRU, provided that we meet certain diligence milestones,
including but not limited to, (i) delivering a development plan within 18 months, (ii) raising $3 million in either equity, debt, or grant
funding, or a combination thereof within 18 months, (iii), generating sufficient preclinical data to support the identification of the
initial field of use to support the initial planned clinical indication for the technology, (iv) determining manufacturing processes and
cGMP requirements to manufacture the initial product for use in toxicology studies, and (v) identifying required toxicology studies required
to support Phase I clinical trials in the initial field of use. In addition, the parties agreed to the royalty rates payable on net sales
of licensed products to fall within the range of 4% to 8% and the parties agree to negotiate in good faith on the final licensing terms. Under the License Option Agreement, Private Mosaic
issued CWRU 70,000 shares of Class B Common Stock at the fair market value of $7 on the date of issuance, representing 10% of the fully
diluted shares of common stock outstanding of Private Mosaic. On August 21, 2020, the Class B Stock was exchanged for shares of Series
B Preferred under the Reverse Merger, which included certain anti-dilution rights. Pursuant to the Certificate of Designation, the Series
B Preferred holder will continue to maintain ownership equal to 10% of the fully diluted shares of common stock outstanding of the Company,
including for such purposes all other convertible securities outstanding and reserved for issuance except stock options issued and outstanding
and reserved for issuance under a board approved employee stock option plans reserving for issuance no more than ten percent (10%) of
the outstanding common stock of the Company then outstanding, until we initially raise at least $1 million from the sale of either preferred
or common stock, or a combination thereof (“Capital Threshold”). In addition, pursuant to the License Option Agreement, net
working capital acquired under the Reverse Merger of approximately $374,000 was applied against the Capital Threshold (see Note 2). As
of June 30, 2021, the remaining Capital Threshold was approximately $ 626,000 3 In addition, we are responsible for the reimbursement
of all patent fees incurred by CWRU under the License Option Agreement from the effective date of the License Option Agreement. During
the three and six months ended June 30, 2021, we incurred $ 11,438 22,817

Notes On May 7, 2021 (“Effective Date”),
we entered into a convertible note purchase agreement (“Note Agreement”) with five (5) accredited investors, including two
(2) members of our Board of Directors that participated on the same terms as other accredited investors (collectively, the “Investors”).
Pursuant to the Note Agreement, the Company received $ 525,003 49,997 575,000 The Convertible Notes have no stated maturity
date; bear interest at a simple rate equal to eight percent ( 8.0 6,931 The Convertible Notes will convert into the same
equity securities offered in the Qualified Financing or Smaller Financing (“Conversion Shares”), as described below, at a
conversion price equal to the lower of (i) the product equal to 80% times the lowest per unit purchase price of the equity securities
issued for cash in the Qualified Financing or Smaller Financing, or (ii) $ 2.377 Pursuant to the Note Agreement, a Qualified Financing
represents a single transaction or series or transactions whereby the Company receives aggregate gross proceeds of at least $5 million
from the sale of equity securities following the Effective Date (excluding proceeds from the issuance of any future Convertible Notes).
A Smaller Financing represents any sale of equity securities whereby the aggregate gross proceeds are less than $5 million (excluding
proceeds from the issuance of any future Convertible Notes). In addition, in the event of a corporate transaction
covering the sale of all or substantially all of the Company’s assets, or merger or consolidation with or into another entity,
or change in ownership of at least 50% in voting securities of the Company, the holder of the Convertible Note may elect that either:
(a) the Company pay the holder of such Convertible Note an amount equal to the sum of (i) all accrued and unpaid interest due on such
Convertible Note and (ii) one and one-half (1.5) times the outstanding principal balance of such Convertible Note; or (b) such Convertible
Note will convert into that number of conversion shares equal to the quotient obtained by dividing (i) the outstanding principal balance
and unpaid accrued interest of such Convertible Note on the date of conversion by (ii) $2.377. The Company follows ASC 480-10, “Distinguishing Liabilities from Equity” in its evaluation of the accounting for share-settled
debt. ASC 480-10-25-14 requires liability accounting for certain financial instruments, including shares that embody an unconditional
obligation to transfer a variable number of shares, provided that the monetary value of the obligation is based solely or predominantly
on one of the following three characteristics:
a) A fixed monetary amount known at inception;
b) Variations in something other than the fair value of the issuer’s equity shares; or
c) Variations in the fair value of the issuer’s equity shares, but the monetary value to the counterparty
moves in the opposite direction as the value of the issuer’s shares Moreover, equity classification was not an appropriate
classification for the Convertible Notes because the underlying terms of the Convertible Notes do not expose the Investors to risks and
rewards similar to those of an owner and, therefore, do not create a shareholder relationship. We are instead using our equity shares
as the currency to settle our obligation. In addition, pursuant to ASC 835-30, the Convertible Notes were initially recorded at their
amortized cost of $ 575,000 718,750 41,002

Equity and Share-Based Compensation Stockholders’ Equity The Company’s authorized capital consists
of 100,000,000 shares of common stock, par value $0.00001 per share, and 5,000,000 shares of preferred stock, par value $0.00001 per share
(“Preferred Stock”). Under the Reverse Merger (see Notes 1 and 2), we designated and issued 630,000 shares of Series A Convertible
Voting Preferred Stock (“Series A Preferred”) and 70,000 shares of Series B Convertible Voting Preferred Stock (“Series
B Preferred”). Series A Preferred On August 21, 2020, the Company issued 630,000
shares of Series A Preferred (classified as permanent equity), in exchange for 630,000 shares of Class A Common Stock of Private Mosaic.
Each share of Series A Preferred has a par value of $0.00001 per share, no dividend rate, a stated value of $6.50 per share, and each
share of Series A Preferred converts into 10.194106 shares of common stock of the Company (“Series A Conversion Number”).
In addition, the Series A Preferred possessed full voting rights prior to conversion, on an as-converted basis, as the common stock of
the Company, as defined in the Series A Certificate of Designation. On January 29, 2021, 630,000 shares of Series
A Preferred automatically converted into an aggregate 6,422,290 shares of common stock upon the effectiveness of a registration statement
registering the resale of the underlying shares. The registration statement on Form S-3 was declared effective by the SEC on January 29,
2021. Series B Preferred On August 21, 2020, the Company issued 70,000
shares of Series B Preferred (classified as permanent equity), in exchange for 70,000 shares of Class B Common Stock of Private Mosaic.
Each share of Series B Preferred has a par value of $0.00001 per share, no dividend rate, a stated value of $6.50 per share, and each
share of Series B Preferred converts into 11.46837 shares of common stock of the Company (“Series B Conversion Number”). In
addition, the Series B Preferred possesses full voting rights, on an as-converted basis, as the common stock of the Company, as defined
in the Series B Certificate of Designation. Furthermore, the Series B Preferred does not have any mandatory conversion rights and only
converts upon written notice from the holder. The Series B Preferred also includes certain anti-dilution
rights (“anti-dilution issuance rights”), whereby the holder of Series B Preferred will continue to maintain ownership equal
to 10% of the fully diluted shares of common stock outstanding, including for such purposes all other convertible securities outstanding
and reserved for issuance except equity awards issued and outstanding and reserved for issuance under a board approved equity compensation
plan reserving for issuance no more than ten percent (10%) of the outstanding common stock of the Company then outstanding, until we raise
at least $1 million from the sale of either preferred or common stock, or a combination thereof (“Capital Threshold”). In
addition, pursuant to the License Option Agreement, any net working capital acquired under a reverse merger or acquisition shall be applied
against the Capital Threshold. The net working capital of PTSC on the Closing Date was approximately $374,000 (see Note 2). As such, the
remaining Capital Threshold was approximately $626,000 as of June 30, 2021. The anti-dilution issuance rights meet the definition of a
derivative instrument under FASB’s ASC Topic 815 (see Note 3). In the event of any Liquidation Event, the Holders
of Series B Preferred shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds
of the Company to the holders of common stock, an amount per share in cash equal to the greater of (x) the stated value of $6.50 for each
share of Series B Preferred then held by the holder or (y) the amount payable per share of common stock which such holder of Series
B Preferred would have received if such Holder had converted to common stock immediately prior to the Liquidation Event. Share-Based Compensation 2020 Omnibus Incentive Plan On October 21, 2020, we adopted our 2020 Omnibus
Incentive Plan (the “2020 Plan”) and on October 22, 2020, the 2020 Plan was approved by our stockholders. The 2020 Plan was
adopted to promote our long-term success and the creation of stockholder value by motivating participants, through equity incentive awards,
to achieve long-term success in our business. The 2020 Plan permits the discretionary award of stock options, restricted stock, RSUs,
and other equity awards to selected participants. On the first anniversary date from the adoption date of the 2020 Plan (or October 21,
2021), the number of shares of common stock reserved for issuance under the 2020 Plan shall automatically increase to 20% of the fully
diluted shares of common stock outstanding, including shares of common stock reserved for issuance under convertible securities, such
as the shares issuable upon the conversion of Series B Preferred, as calculated on an as-converted basis. As of June 30, 2021, we have
reserved 802,785 466,739 336,046 The cost of all share-based awards will be recognized
in the consolidated financial statements based on the fair value of the awards. The fair value of stock option awards will be determined
using the Black-Scholes valuation model on the date of grant. The fair value of restricted stock awards and RSUs will be equal to the
closing market price of our common stock on the date of grant. The Company will generally recognize share-based compensation expense
over the period of vesting or period that services will be provided for all time-based awards. Share-based compensation expense for the
three and six months ended June 30, 2021 was comprised of the following:

9. Commitments and Contingencies9. Commitments and Contingencies Legal Matters While the Company is not involved in any litigation
as of June 30, 2021, the Company may be involved in various lawsuits and claims arising in the ordinary course of business, including
actions with respect to intellectual property, employment, and contractual matters. Any litigation could have a material adverse effect
on the Company’s business, financial condition, results of operations, and/or cash flows in the period in which the unfavorable
outcome occurs or becomes probable, and potentially in future periods. Indemnification We have made certain guarantees and indemnities,
under which we may be required to make payments to a guaranteed or indemnified party. We indemnify our directors, officers, employees,
and agents to the maximum extent permitted under the laws of the State of Delaware. The duration of the guarantees and indemnities varies,
and in many cases is indefinite. These guarantees and indemnities do not provide for any limitation of the maximum potential future payments
we could be obligated to make. Historically, we have not been obligated to make any payments for these obligations and no liabilities
have been recorded for these guarantees and indemnities in the accompanying unaudited condensed consolidated balance sheets. Escrow Shares On August 31, 2009, we gave notice to the former
shareholders of Crossflo and Union Bank of California (the “Escrow Agent”) under Section 2.5 of the Agreement and Plan of
Merger between us and Crossflo (the “Agreement”), outlining damages incurred by us in conjunction with the acquisition of
Crossflo, and seeking the return of 5,690 shares of our common stock held by the Escrow Agent. Subsequently, former shareholders of Crossflo,
representing a majority of the escrowed shares responded in protest to our claim, delaying the release of the escrowed shares until a
formal resolution is reached. In the event we fail to prevail in our claim against the escrowed shares, we may be obligated to deposit
into escrow approximately $256,000 of cash consideration due to the decline in our average stock price over the one-year escrow period
calculated in accordance with Section 2.5 of the Agreement. We have evaluated the potential for loss regarding our claim and believe
that it is probable that the resolution of this issue will not result in a material obligation to the Company, although there is no assurance
of this. Accordingly, we have not recorded a liability for this matter. Patent Expenses Under the License Option Agreement (see Note 6),
if we enter into a license agreement with CWRU, we would be responsible for the reimbursement of all past patent costs incurred by CWRU
though the date of the License Option Agreement, which amount has been estimated to be approximately $ 267,000

Basis of PresentationBasis of Presentation The accompanying unaudited condensed consolidated
financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly
reports on Form 10-Q and do not include all of the information and footnotes required by accounting principles generally accepted in the
United States of America. All intercompany accounts and transactions have been eliminated. In conjunction with the Reverse Merger, Private
Mosaic’s historical results of operations replaced PTSC’s historical results of operations for all periods prior to the Reverse
Merger and, for all periods following the Reverse Merger, the results of operations of the combined company are included in the Company’s
unaudited condensed consolidated financial statements. Since Private Mosaic was incorporated on March 30, 2020, prior year financial information
covers the period March 30, 2020 (date of inception) to June 30, 2020. In addition, operating results for the three months ended June
30, 2021 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2021. The accompanying unaudited condensed consolidated
financial statements have been prepared assuming the Company will continue as a going concern. In the opinion of management, the interim
condensed consolidated financial statements reflect all adjustments of a normal recurring nature necessary for a fair presentation of
the results for the interim period presented.
Segment ReportingSegment Reporting The Company manages its operations as a single
operating segment for the purposes of assessing performance and making operating decisions. No revenue has been generated since inception,
and all tangible assets are held in the United States.
Reverse MergerReverse Merger On August 21, 2020, Private Mosaic completed
a Reverse Merger with PTSC pursuant to which Private Mosaic merged into PTSC (see Note 1). Due to the nominal assets and limited operations
of PTSC prior to the Reverse Merger, the transaction was treated as a reverse acquisition under the provision of Financial Accounting
Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805 whereby Private Mosaic became the
accounting acquirer (legal acquiree) and PTSC was treated as the accounting acquiree (legal acquirer). As the transaction was treated
as a reverse asset acquisition, no intangibles, including goodwill, were recognized. The net tangible assets acquired and liabilities
assumed totaled $374,435 which were acquired by Private Mosaic in connection with the transaction and were recorded at their estimated
acquisition date fair values as of the Closing Date, as follows:
Schedule of assets acquired and liabilities assumed

Financial Instruments and Concentrations of Credit RiskFinancial Instruments and Concentrations of
Credit Risk Financial instruments that potentially subject
us to concentrations of credit risk consist principally of cash and cash equivalents. We invest our cash and cash equivalents primarily
in money market funds. Cash and cash equivalents are maintained with high quality financial institutions, which are regularly monitored
by management. At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit
Insurance Corporation and the Securities Investor Protection Corporation. We perform ongoing evaluations of these financial institutions
to limit our concentration of risk exposure.
Fair Value of Financial InstrumentsFair Value of Financial Instruments Our financial instruments consist principally
of cash and cash equivalents, accounts payable, accrued payable to founders, derivative liability, accrued expenses and other, and convertible
notes. The carrying value of these financial instruments, except for the derivative liability and convertible notes, approximates fair
value because of the immediate or short-term maturity of the instruments. We record the derivative liability at fair value (see Note 3).
The convertible notes are initially recorded at their amortized cost and are being accreted to their redemption value over the estimated
conversion period using the effective interest method (see Note 7).
Use of EstimatesUse of Estimates The preparation of consolidated financial statements
in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during
the reporting period. Significant estimates in these unaudited condensed consolidated financial statements include those related to the
fair value of the anti-dilution issuance rights liability (derivative liability), the timing of conversion of the convertible notes, the
provision or benefit for income taxes and the corresponding valuation allowance on deferred tax assets. In addition, management’s
assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash
inflows and outflows. On an ongoing basis, the Company evaluates its estimates, judgments, and methodologies. The Company bases its estimates
on historical experience and on various other assumptions believed to be reasonable. Due to the inherent uncertainty involved in making
such accounting estimates and assumptions, the actual financial statement results could differ materially from such accounting estimates
and assumptions.
Convertible NotesConvertible Notes The Company follows ASC 480-10, “Distinguishing
Liabilities from Equity” in its evaluation of the accounting for share-settled debt. ASC 480-10-25-14 requires liability accounting
for certain financial instruments, including shares that embody an unconditional obligation to transfer a variable number of shares, provided
that the monetary value of the obligation is based solely or predominantly on one of the following three characteristics:
a) A fixed monetary amount known at inception;
b) Variations in something other than the fair value of the issuer’s equity shares; or
c) Variations in the fair value of the issuer’s equity shares, but the monetary value to the counterparty
moves in the opposite direction as the value of the issuer’s shares Moreover, equity classification was not an appropriate
classification for the convertible notes because the underlying terms of the convertible notes do not expose the investors to risks and
rewards similar to those of an owner and, therefore, do not create a shareholder relationship. Pursuant to ASC 835-30, the convertible
notes were initially recorded at their amortized cost and are being accreted to their redemption value over the estimated conversion period
using the effective interest method (see Note 7).
Assessment of Contingent LiabilitiesAssessment of Contingent Liabilities We may be involved in various legal matters, disputes,
and patent infringement claims which arise in the ordinary course of our business. We accrue for any estimated losses at the time when
we can make a reliable estimate of such loss and it is probable that it has been incurred. By their very nature, contingencies are difficult
to estimate. We continually evaluate information related to all contingencies to determine that the basis on which we have recorded our
estimated exposure is appropriate.
Share-Based CompensationShare-Based Compensation We account for restricted stock units (“RSUs”)
and other share-based awards granted under our equity compensation plan in accordance with the authoritative guidance for share-based
compensation. The fair value of RSUs is measured at the grant date based on the closing market price of our common stock on the date of
grant and is recognized as expense on a straight-line basis over the period of vesting. Forfeitures are recognized as a reduction of share-based
compensation expense as they occur. At June 30, 2021, there were no outstanding share-based awards with market or performance conditions. In addition, we periodically grant RSUs to non-employee
consultants, which we account for in accordance with the authoritative guidance for share-based compensation. The cost of non-employee
services received in exchange for share-based awards are measured based on either the fair value of the consideration received or the
fair value of the share-based award issued, whichever is more reliably measurable.
Basic and Diluted Income (Loss) Per Common ShareBasic and Diluted Income (Loss) Per Common
Share Basic income (loss) per common share is computed
by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period.
Diluted earnings per common share is computed by dividing our net income (loss) available to common stockholders by the sum of the weighted
average number of common shares outstanding during the period, plus the potential dilutive effects of unvested RSUs and shares of common
stock expected to be issued under our Series A Preferred and Series B Preferred outstanding during the period. The potential dilutive effect of unvested RSUs
outstanding during the period are calculated in accordance with the treasury stock method, but are excluded if their effect is anti-dilutive.
The potential dilutive effect of our Series B Preferred outstanding during the period is calculated using the if-converted method assuming
the conversion of Series B Preferred as of the earliest period reported or at the date of issuance, if later, but are excluded if their
effect is anti-dilutive. The following table presents the securities excluded
from the calculation of diluted net income (loss) per share for the three and six months ended June 30, 2021 and the three months ended
June 30, 2020 and period March 30, 2020 (date of inception) to June 30, 2020, as the effect of their inclusion would have been anti-dilutive
during periods of net loss:

Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “Income Taxes (Topic 740): Simplifying
the Accounting for Income Taxes” (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain
exceptions and improving consistent application in certain areas of Topic 740. ASU 2019-12 is effective for fiscal years, and interim
periods within those years, beginning after December 15, 2020, however, early adoption is permitted. The Company adopted ASU 2018-13 effective
January 1, 2021. Implementation of this guidance did not have a material impact on the Company’s unaudited condensed consolidated
