Patriot Scientific Corporation

Notes to Unaudited Condensed Consolidated Financial Statements

1. Basis of Presentation and Summary of Significant Accounting Policies

The unaudited condensed consolidated financial statements of Patriot Scientific Corporation (the “Company”, “PTSC”, “Patriot”, “we”, “us” or “our”) presented herein 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. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Report on Form 10-K for our fiscal year ended May 31, 2011.

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. Operating results for the six month period ended November 30, 2011 are not necessarily indicative of the results that may be expected for the year ending May 31, 2012.

Basis of Consolidation

The condensed consolidated balance sheets at November 30, 2011 and May 31, 2011 include our accounts and those of our wholly owned subsidiary Patriot Data Solutions Group, Inc. (“PDSG”) which includes Crossflo Systems, Inc. (“Crossflo”), and our inactive subsidiary Plasma Scientific Corporation. All significant intercompany accounts and transactions have been eliminated.

The condensed consolidated statement of operations for the three months ended November 30, 2011 and 2010 and the six months ended November 30, 2011 includes our accounts, and those of our wholly owned subsidiary PDSG which includes Crossflo, and our inactive subsidiary Plasma Scientific Corporation. All significant intercompany accounts and transactions have been eliminated.

The condensed consolidated statement of operations for the six months ended November 30, 2010 includes our accounts, and those of our wholly owned subsidiary PDSG which includes Crossflo, the business line of Vigilys (until August 2010) and our inactive subsidiary Plasma Scientific Corporation. All significant intercompany accounts and transactions have been eliminated.

Liquidity and Management’s Plans

Cash shortfalls currently experienced by Phoenix Digital Solutions, LLC (“PDS”) and continued negative cash flows incurred by PDSG will have an adverse effect on our liquidity. Accordingly, we have and may continue to examine alternatives that could allow for the partnering or divestiture of PDSG. If successful, these measures may provide for a further reduction in expenses and cash use, or additionally in the event of divestiture, cash proceeds, although given the operational history of PDSG to date there can be no guarantee that a divestiture will result in the realization of material consideration. With respect to PDS, although we presently do not have any contractual commitments to fund any cash requirements (see Note 6), in December 2011 we did contribute $200,000 in additional capital to PDS, in order to fund a portion of a legal retainer discussed below. In addition, we do not have any intention of funding any cash requirements of our 50% partner in PDS, Technology Properties Limited, Inc. (“TPL”).

Patriot Scientific Corporation

Notes to Unaudited Condensed Consolidated Financial Statements

Liquidity and Management’s Plans (continued)

Our current liquid cash resources as of November 30, 2011, are expected to provide the funds necessary to support our operations through at least the next twelve months assuming we do not continue to fund the obligations of PDS. The cash flows from our interest in PDS represent our primary significant source of cash generation. In the event of a continued decrease or interruption in MMP Portfolio licensing we will incur a significant reduction to our cash position as the revenues from our PDSG subsidiary are insufficient to cover the costs of their operations and the costs of Patriot Scientific Corporation as a whole. It is highly unlikely that we would be able to obtain any additional sources of financing to supplement our cash and short-term investment position of $8,975,788 at November 30, 2011. In December 2011, TPL engaged new counsel on behalf of PDS, and committed PDS to paying an initial retainer in the amount of $2,400,000, payable in monthly installments from December 2011 through August 2012. The $200,000 that we contributed to PDS referred to above, was used to pay the first installment of such retainer. The remaining balance of the retainer is anticipated to be funded by PDS from licensing revenues. In the event that PDS does not have the funds to pay one or more installments of the retainer, we and TPL must decide whether to contribute additional capital to PDS to fund such installments. The newly retained counsel will continue the Northern California cases to trial after the claims construction hearing.

Investments in Marketable Securities

We determine the appropriate classification of our investments at the time of purchase and reevaluate such designation at each balance sheet date. Our investments in marketable securities have been classified and accounted for as available-for-sale based on management’s investment intentions relating to these securities. Available-for-sale marketable securities are stated at fair market value. Unrealized gains and losses, net of deferred taxes, are recorded as a component of other comprehensive income (loss). We follow the authoritative guidance to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in fair value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net in the condensed consolidated statements of operations.

Investment in Affiliated Company

We review our investment in PDS to determine whether events or changes in circumstances indicate that the carrying amount may not be recoverable. The primary factors we consider in our determination are the financial condition, operating performance and near term prospects of PDS. If the decline in value is deemed to be other than temporary, we would recognize an impairment loss.

We have a 50% interest in PDS (see Note 6). As of the date of this filing, PDS is a variable interest entity (“VIE”) of which we are not the primary beneficiary and therefore will not consolidate PDS’ financial statements with our own as we cannot direct the licensing activity of TPL on behalf of PDS.

This investment is accounted for using the equity method of accounting since the investment provides us the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of the investee of between 20% and 50%, although other factors, such as representation on the investee’s board of directors, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting, the investment, originally recorded at cost, is adjusted to recognize our share of net earnings or losses of the investee which is presented in the condensed consolidated statements of operations in the caption “Equity in loss of affiliated company” and also is adjusted by contributions to and distributions from PDS.

Patriot Scientific Corporation

Notes to Unaudited Condensed Consolidated Financial Statements

Investment in Affiliated Company (continued)

During the six months ended November 30, 2011, our share of loss in PDS exceeds our investment in PDS by $1,563,261. We presently do not have a contractual obligation to fund any cash requirements of PDS (see Note 6) and accordingly we have not recorded the excess loss on our consolidated financial statements, which is a change in our policy of accounting for PDS. Under the equity method of accounting, we are to continue to report losses up to our carrying amount of the investment and advances. Once the investment balance is reduced to $0, we are to discontinue applying the equity method until such time that our share of future net income reported by PDS equals our share of net losses not recognized during the period the equity method was suspended.

Comprehensive Income (Loss)

Comprehensive income (loss) includes unrealized gains and losses which are excluded from the condensed consolidated statements of operations.

Revenue Recognition

Revenue from technology license agreements is recognized at the time a contract is entered into, the license method is determined (paid-in-advance or on-going royalty), and the customer is provided with the licensed technology, if applicable.

PDSG sells software and services to end users primarily through relationships with systems integrators and prime contractors. PDSG recognizes revenue in accordance with authoritative guidance for the software industry. PDSG’s revenue is derived primarily from the following sources: (i) software licensing, (ii) related professional services, and (iii) post contract customer support (“PCS”) agreements. PCS agreements typically include software updates, on a when and if available basis, telephone and Internet access to technical support personnel. Software updates provide customers with rights to unspecified software product upgrades and to maintenance releases and patches released during the term of the support period.

PDSG’s contracts with customers, including systems integrators and prime contractors, are multiple element arrangements which contain professional services that are considered essential to the functionality of the other elements of the arrangement. PDSG accounts for revenue on these arrangements according to authoritative guidance for contract accounting. Under this guidance, PDSG recognizes revenue based on progress towards contract completion measured by actual hours incurred in relation to the estimate of total expected hours. PDSG measures these revenues by applying the contract-specific estimated percentage of completion to the total contract amount for software and professional services. PDSG routinely updates the estimates of future hours for agreements in process and reports any cumulative effects of such adjustments in current operations. PDSG immediately recognizes any loss expected on these contracts when it is projected that loss is probable.

We allocate PDSG’s revenues to all deliverables based on their relative selling price using a specific hierarchy. The hierarchy is as follows: vendor-specific objective evidence (“VSOE”), third-party evidence of selling price (“TPE”) or best estimate of selling price (“BESP”). When a sale involves multiple elements, PDSG allocates the entire fee from the arrangement to each respective element based on VSOE of fair value and recognizes revenue when each element’s revenue recognition criteria are met. VSOE of fair value for each element is established based on the price charged when the same element is sold separately. PDSG has established VSOE for its CDX software licenses and PCS based on historical stand-alone sales to third parties or from the stated renewal rates contained in the customer contracts. PCS is recognized on a straight-line basis over the support period.

Patriot Scientific Corporation

Notes to Unaudited Condensed Consolidated Financial Statements

Revenue Recognition (continued)

PDSG has not yet demonstrated VSOE for the professional services that are rendered in conjunction with its software license sales. In accordance with the hierarchy we would attempt to establish the selling price of professional services using TPE. PDSG’s product contains significant differentiation such that the comparable pricing of products with similar functionality cannot be obtained. PDSG is typically not able to obtain TPE for professional services.

When we are unable to establish selling prices using VSOE or TPE, we use BESP. The objective of BESP is to determine the price at which PDSG would transact a sale if professional services were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for highly customized offerings which is the case with PDSG’s professional services deliverable.

Research and Development

Research and development costs are expensed as incurred and primarily include payroll and related benefit costs and contractor fees.

Basic net loss per share includes no dilution and is computed by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution of securities that could share in the earnings of an entity.

For the three and six months ended November 30, 2011 potential common shares of 2,895,000 related to our outstanding options were not included in the calculation of diluted income per share as we had no income. For the three and six months ended November 30, 2010 potential common shares of 5,637,292 related to our outstanding warrants and options were not included in the calculation of diluted income per share as we had no income. Had we reported net income for the three and six months ended November 30, 2011 and 2010, an additional 0 and 755,000 shares of common stock, respectively, would have been included in the number of shares used to calculate diluted earnings per share and an additional 0 and 755,000 shares of common stock, respectively, would have been included in the number of shares used to calculate diluted earnings per share.

In connection with our acquisition of Crossflo, which is now a part of PDSG, we issued escrow shares that are contingent upon certain representations and warranties made by Crossflo at the time of the merger agreement (see Note 9). We exclude these escrow shares from the basic loss per share calculations and include the escrowed shares in the diluted earnings per share calculations.

Share-Based Compensation

Share-based compensation expense recognized during the three and six months ended November 30, 2011 and 2010 is based on the grant date fair value of the portion of share-based payment awards ultimately expected to vest during the year. As share-based compensation expense recognized in the condensed consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeiture rates are based on historical forfeiture experience and estimated future employee forfeitures.

Income Taxes

We follow authoritative guidance in accounting for uncertainties in income taxes. This authoritative guidance prescribes a recognition threshold and measurement requirement for the financial statement recognition of a tax position that has been taken or is expected to be taken on a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under this guidance we may only recognize tax positions that meet a “more likely than not” threshold.

We follow authoritative guidance to evaluate whether a valuation allowance should be established against our deferred tax assets based on the consideration of all available evidence using a “more likely than not” standard. In making such judgments, significant weight is given to evidence that can be objectively verified. We are assessing our deferred tax assets under more likely than not scenarios in which they may be realized through future income.

During the fiscal 2011, we determined that is was not more likely than not that all of our deferred tax assets will be realized in the future due to our continuing pre-tax and taxable losses. As a result of this determination we have placed a full valuation allowance against our deferred tax assets.

We follow authoritative guidance to adjust our effective tax rate each quarter to be consistent with the estimated annual effective tax rate. We are also required to record the tax impact of certain discrete items, unusual or infrequently occurring, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings or losses versus annual projections.

Assessment of Contingent Liabilities

We are 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.

2 . Goodwill and Other Intangible Assets

Goodwill originating from acquisitions was not amortized and was tested for impairment on an annual basis and between annual tests based on certain circumstances.

Changes in the net carrying amount of goodwill were as follows:

Balance, June 1, 2010	$	642,981
Impairment of Crossflo goodwill		(642,981	)
Balance May 31, 2011	$	-

During the quarter ended November 30, 2010, we wrote-off the remaining goodwill associated with our acquisition of Crossflo due to the inability of PDSG to meet its business plan. We recorded this as an impairment of goodwill on our consolidated statement of operations for the nine months ended February 28, 2011.

Goodwill and Other Intangible Assets (continued)

Purchased identifiable intangible assets were being amortized on a straight-line basis over their estimated lives. Management’s plan of restructuring and the continuing inability of PDSG to meet its business plan were indicators of potential impairment on our intangible assets. Accordingly, during the fiscal year ended May 31, 2011 it was determined that intangibles were fully impaired by approximately $1,470,000. We have recorded this as an impairment of purchased intangibles on our consolidated statement of operations for the fiscal year ended May 31, 2011.

The amortization expense related to intangible assets was as follows:

	Three Months Ended		Six Months Ended		Three Months Ended		Six Months Ended
	November 30, 2011		November 30, 2011		November 30, 2010		November 30, 2010

3. Cash, Cash Equivalents, Restricted Cash and Marketable Securities

We consider all highly liquid investments with original maturities of three months or less to be cash equivalents.

Restricted cash and cash equivalents at November 30, 2011 and May 31, 2011 consist of deposits in a savings account required to be held as collateral for our corporate credit card.

At November 30, 2011 and May 31, 2011, our current portion of marketable securities in the amount of $3,287,457 and $2,207,009, respectively, consists of the par value plus accrued interest of our time deposits. At November 30, 2011, our non-current portion of marketable securities in the amount of $245,336 consists of the par value plus accrued interest of time deposits. These marketable securities are classified as available for sale and are reported at fair market value.

We follow authoritative guidance to account for our marketable securities as available for sale. 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).

During September 2010, we reached a confidential settlement agreement with Deutsche Bank. Under terms of the agreement, we transferred approximately $5.2 million in illiquid auction rate securities instruments to Deutsche Bank for a substantial portion of the face value of the securities, and if the instruments are redeemed by a certain date then we will receive the full face amount of the instruments. On October 4, 2010, we received settlement proceeds from Deutsche Bank of $4,551,260 plus $6,330 of interest income.

Beginning in fiscal 2011, we purchased certificates of deposit with varying maturity dates greater than three months. The following table summarizes the maturities, gross unrealized gains or losses and fair value of the certificates of deposit as of November 30, 2011:

4. Accounts Receivable

Trade accounts receivable at November 30, 2011 and May 31, 2011 is $113,786 and $187,465, respectively, which relates entirely to PDSG. No allowance for doubtful accounts has been recorded at November 30, 2011 or May 31, 2011.

5. Work-In-Process

At November 30, 2011, work-in-process consisting of recognized revenue on PDSG’s current contracts was $442,773 and invoices to customers was $405,875. At May 31, 2011, work-in-process consisting of recognized revenue on PDSG’s current contracts was $455,381 and invoices to customers were $424,800. These amounts are shown on our November 30, 2011 and May 31, 2011 balance sheets at net of $36,898 and $30,581, respectively, due to their immateriality.

6. Investment in Affiliated Company

On June 7, 2005, we entered into a Master Agreement (the “Master Agreement”) with TPL, and Charles H. Moore (“Moore”), the co-inventor of the technology which is the subject of the MMP Portfolio of microprocessor patents, pursuant to which the parties resolved all legal disputes between them. Pursuant to the Master Agreement, we and TPL entered into the Limited Liability Company Operating Agreement of PDS (the “LLC Agreement”) into which we and Moore contributed our rights to certain of our technologies.

We and TPL each own 50% of the membership interests of PDS, and each of us has the right to appoint one member of the three member management committee. The two appointees are required to select a mutually acceptable third member of the management committee. There has not been a third management committee member since May 2010, nor are there any current attempts to seek a replacement member. Pursuant to the LLC Agreement, we and TPL agreed to establish a working capital fund for PDS of $4,000,000, of which our contribution was $2,000,000. The working capital fund increases to a maximum of $8,000,000 as license revenues are achieved. We and TPL are obligated to fund future working capital requirements at the discretion of the management committee of PDS in order to maintain working capital of not more than $8,000,000. If the management committee determines that additional capital is required, neither we nor TPL are required to contribute more than $2,000,000 in any fiscal year. Since there is currently not a third member of the management committee, working capital contributions made to PDS require the approval of both management committee members. On December 14, 2011 we contributed $200,000 and TPL forfeited rights to $200,000 of special litigation support payments due it pursuant to the October 6, 2011 settlement agreement for an in-kind capital contribution of $200,000 in order to fund a portion of a retainer due to new counsel engaged (see Note 1, Liquidity and Management’s Plans). Distributable cash and allocation of profits and losses will be allocated to the members in the priority defined in the LLC Agreement. PDS has committed to pay a quarterly amount ranging between $500,000 and $1,000,000 (based upon a percentage of the working capital fund balance of PDS) for supporting efforts to secure licensing agreements by TPL on behalf of PDS. During the six months ended November 30, 2011 and 2010, PDS expensed $1,000,000 and $500,000, respectively, pursuant to this commitment. This expense is recorded in the accompanying statements of operations presented below.

Investment in Affiliated Company (continued)

PDS reimburses TPL for payment of all legal and third-party expert fees and other related third-party costs and other expenses. During the six months ended November 30, 2011 and 2010, PDS expensed $3,296,798 and $2,017,463, respectively, pursuant to the agreement. These expenses are recorded in the accompanying PDS statements of operations presented below.

On April 12, 2010, we filed an action against TPL in the San Diego Superior Court. On January 19, 2011, pursuant to our settlement agreement with TPL, PDS agreed to pay TPL $67,000 per month from September 1, 2010 to April 30, 2011 relating to TPL’s special work and effort regarding internal costs related to litigation support and patent re-examinations.

On April 22, 2010, we filed an action against TPL in the Superior Court of Santa Clara County. We and TPL had been in negotiations to restructure our relationship. On October 6, 2011, we announced that we had settled this action. Pursuant to this executed settlement agreement with TPL, PDS agreed to pay TPL $172,000 for June 2011, and $86,000 per month thereafter until 60 days after the Markman hearing relating to TPL’s special work and effort regarding internal costs related to litigation support. Accordingly, PDS has accrued $602,000 at November 30, 2011 pursuant to the executed settlement agreement and this expense is recorded in the accompanying PDS statements of operations presented below.

We are accounting for our investment in PDS under the equity method of accounting, and accordingly have recorded our reportable share of PDS’ net loss during the six months ended November 30, 2011 and 2010 of $527,551 and $1,475,839, respectively, as a decrease in our investment. We received no cash distributions from PDS during the six months ended November 30, 2011 and 2010. During the three months ended November 30, 2011, we accounted for $227,268 previously advanced by us for legal services which are reimbursable by PDS, under the equity method of accounting given that this amount remains unreimbursed at November 30, 2011. Accordingly, our investment in and advances to PDS are $0 and $227,268. During the During the six months ended November 30, 2011 our entire share of PDS’ net loss is $2,090,812 and at May 31, 2011 our investment in PDS was $300,283. For the six months ended November 30, 2011 we have recorded our share of PDS’ net loss to the extent of our basis in the investment. The remaining loss will be carried forward until such time as it can be recovered. Accordingly, our investment in PDS is $0 on our November 30, 2011 balance sheet. We have recorded our share of PDS’ net loss for the six months ended August 31, 2011 as “Equity in loss of affiliated company” in the accompanying condensed consolidated statements of operations.

During the three months ended November 30, 2011 and 2010, TPL entered into licensing agreements with third parties, pursuant to which PDS received aggregate proceeds of $45,000 and $1,409,000, respectively.

During the six months ended November 30, 2011 and 2010, TPL entered into licensing agreements with third parties, pursuant to which PDS received aggregate proceeds of $557,300 and $1,409,000, respectively.

At November 30, 2011, PDS had accounts payable balances of approximately $2,965,704 and $227,000 to TPL and PTSC, respectively. At May 31, 2011, PDS had accounts payable balances of approximately $1,754,000 and $129,000 to TPL and PTSC, respectively.

Variable Interest Entity Disclosures

On January 9, 2012, PDS’ cash and cash equivalents balance was $314,388. Management has concluded that our equity investment at risk in PDS is insufficient to finance its activities as the volume of license revenue has not supported litigation costs independent of additional working capital funding.

We have not provided financial support to PDS other than required capital contributions and the $200,000 contribution we agreed to make in December 2011 as described above, and we are not contractually obligated to provide financial support to PDS other than to fund the working capital account at the discretion of PDS’ management committee. In the event we, and not TPL, provide working capital funding to PDS we would consolidate PDS’ financial statements with our own as our ownership in PDS would be greater than 50%.

Our variable interest in PDS consists of 50% of PDS’ Members Equity (Deficit) in addition to the accounts payable balance due us for a total of $(2,017,797) at November 30, 2011. We are unable to quantify our maximum exposure to loss associated with this VIE, however, we do not have any contractual commitments and do not intend to fund any cash requirements of PDS.

PDS’ balance sheets at November 30, 2011 and May 31, 2011 and statements of operations for the three and six months ended November 30, 2011 and 2010 are as follows:

7. Income Taxes

During the third quarter of fiscal 2011, we determined that it was not more likely than not that all of our deferred tax assets will be realized in the future due to our continuing pre-tax and taxable losses. As a result of this determination we have placed a full valuation allowance against our deferred tax assets. There have been no changes to our determination during the current fiscal year.

8. Stockholders’ Equity

Share Repurchases

During July 2006, we commenced our Board of Director approved stock buyback program in which we repurchase our outstanding common stock from time to time on the open market. As part of the program we purchased 974,550 and 844,193 shares of our common stock at an aggregate cost of $66,387 and $96,835 during the six months ended November 30, 2011 and 2010, respectively.

Stockholders’ Equity (continued)

Stock Options and Warrant Activity

As of November 30, 2011, we had 125,000 options outstanding pursuant to our 2001 Stock Option Plan exercisable at $0.47 per share expiring in 2012; and 2,770,000 options outstanding pursuant to our 2006 Stock Option Plan exercisable at a range of $0.09 to $0.60 per share expiring through 2015. Some of the options outstanding under the 2006 Stock Option Plan are not presently exercisable and are subject to meeting certain vesting criteria.

During the six months ended November 30, 2011, we recorded $10,012 of share-based compensation expense related to vesting of stock options granted to PDSG employees. During the six months ended November 30, 2010, we recorded $65,984 of share-based compensation expense related to vesting of stock options, including $10,479 related to PDSG.

Share-based Compensation

Summary of Assumptions and Activity

The fair value of share-based awards to employees and directors is calculated using the Black-Scholes option pricing model, even though this model was developed to estimate the fair value of freely tradable, fully transferable options without vesting restrictions, which differ significantly from our stock options. The Black-Scholes model also requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the pricing term of the grant effective as of the date of the grant. The expected volatility for the three and six months ended November 30, 2011 is based on the historical volatilities of our common stock. These factors could change in the future, affecting the determination of share-based compensation expense in future periods.

Stockholders’ Equity (continued)

A summary of option activity as of November 30, 2011 and changes during the six months then ended, is presented below:

	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value
Options outstanding at June 1, 2011		3,010,000		$	0.33
Options granted		-		$	-

Options exercisable at November 30, 2011		2,747,611		$	0.31		1.75	$	-

The weighted average grant date fair value of options granted during the six months ended November 30, 2010 was $0.08. T here were no options exercised during the six months ended November 30, 2011 or 2010.

The aggregate intrinsic value represents the differences in market price at the close of the quarter ($0.05 per share on November 30, 2011) and the exercise price of outstanding, in-the-money options (those options with exercise prices below $0.05) on November 30, 2011.

As of November 30, 2011, there was $12,090 of total unrecognized compensation cost, net of forfeitures, related to employee stock option compensation arrangements. That cost is expected to be recognized on a straight-line basis over the next 18 months.

The following table summarizes employee and director share-based compensation expense for Patriot and employee share-based compensation for PDSG for the three and six months ended November 30, 2011 and 2010, which was recorded as follows:

Litigation

Patent Litigation

On February 8, 2008, we, TPL and Alliacense Ltd. were named as defendants in separate lawsuits filed in the United States District Court for the Northern District of California by HTC Corporation, and Acer, Inc., and affiliated entities of each of them.

The Acer case seeks declaratory relief that its products do not infringe enforceable claims of the '336, ‘749, '148 patents and US 5,530,890 (the “890 patent”). The HTC case similarly seeks declaratory relief that its products do not infringe enforceable claims of those patents. We allege counterclaims for patent infringement of the '336, '749, '148 and '890 patents against Acer and HTC. On June 16, 2009, District Court Judge Jeremy Fogel stayed the HTC and Acer actions until September 18, 2009. The stay has been lifted and the cases are in the discovery and claims construction phase.

A claims construction hearing is scheduled for January 27, 2012. Acer has asked the Court to consider a Motion for Summary Judgment to be decided in February 2012, but a briefing schedule has not been established.

On December 1, 2008, we, TPL and Alliacense, Ltd. were named as defendants in a lawsuit filed in the United States District Court for the Northern District of California by Barco, N.V. The Barco case seeks declaratory relief that its products do not infringe enforceable claims of the '749 and '890 patents. We allege counterclaims for patent infringement of our '749, '890 and '336 patents. On June 22, 2009, Judge Fogel also stayed the Barco case until September 18, 2009. That stay has been lifted and the case is deemed related to the Acer and HTC cases. The case is in the discovery and claims construction phase. Barco moved for Summary Judgment with respect to allegations that it has infringed on the '336 patent on grounds independent of claims construction. That Motion was denied on February 25, 2011.

A claims construction hearing in this matter is also scheduled for January 27, 2012. Barco has asked the Court to consider a Summary Judgment Motion in late February 2012, but a briefing schedule has not been established.

Crossflo Systems, Inc. Litigation

Under the terms of our Agreement and Plan of Merger (the "Merger Agreement") with Crossflo, and certain of its principal officers, an escrow account was established to hold back approximately 10% of the merger consideration payable to the shareholders of Crossflo (the "Escrow Merger Consideration"). See Escrow Shares below. We contend that certain representations and warranties made by Crossflo and certain of its principal officers in the Merger Agreement were false when made, and were false as of the closing of the merger. We submitted a demand to the escrow agent on August 31, 2009 not to release the Escrow Merger Consideration to the Crossflo shareholders and to instead return it to us. A sufficient number of Crossflo shareholders have opposed our demand that the escrow consideration has not been released to either side.

On August 31, 2009, we initiated an arbitration proceeding before the American Arbitration Association against the three Crossflo principal officers who were signatories to the Merger Agreement alleging they provided false representations and warranties in the Merger Agreement and alleging nondisclosure of information about Crossflo during the due diligence process leading up to the merger. Those three principal officers deny our claims and have filed counterclaims for monetary damages alleging libel associated with the making of our demands on escrow and related disclosures in our periodic filings, and misrepresentation associated with our purported intent to fund the operations of Crossflo post acquisition. The arbitration is expected to commence January 24, 2012 and to be completed in February 2012. We have evaluated the potential for loss regarding these issues and believe it is probable that we will prevail although there is no assurance we will. Accordingly, we have not recorded a liability for this matter.

TPL Litigation

On April 22, 2010, we filed an action against TPL and Alliacense LLC in Santa Clara Superior Court alleging claims for breach of contract, breach of fiduciary duty, aiding and abetting breach of fiduciary duty, and interference with contract, constructive fraud, for preliminary and permanent injunctions and for an accounting. The Action stemmed from TPL's notification of a license written in April 2010 which included a license of the MMP patents and other patents to use portfolios and technologies co-owned and potentially owned by TPL in the future. We objected to the amount of license consideration allocated to the MMP patent license as too low relative to the other license components. On October 6, 2011, we settled our dispute with TPL regarding the management of the MMP Portfolio. Pursuant to the terms of the executed settlement agreement, TPL has agreed to: 1) pay PTSC, at the rate of five or ten percent, $1,100,000 of future distributions due to TPL as a member of PDS, (PTSC will recognize these amounts upon a receipt of cash payments from TPL.) 2) TPL has agreed to increased review and procedures by PDS and us on all MMP Portfolio licensing, 3) we have agreed to have PDS pay TPL for certain litigation and reexamination support services at the rate of $172,000 for June 2011, and $86,000 per month thereafter until 60 days after the Markman hearing in the current patent infringement litigation, 4) the parties have agreed to established guidelines and procedures relating to proposed license arrangements to be entered into by TPL involving the MMP Portfolio patents and one or more other patents within TPL’s portfolio that is not an MMP Portfolio patent, and 5) a procedure for allocating revenue between the MMP Portfolio patents and the non-MMP Portfolio patents, if needed.

Commitments and Contingencies (continued)

401(k) Plan

Patriot and PDSG have retirement plans that comply with Section 401(k) of the Internal Revenue Code. All employees are eligible to participate in the plans. Patriot matches 100% of elective deferrals subject to a maximum of 4% of the participant’s eligible earnings. Patriot’s participants vest 33% per year over a three year period in their matching contributions. Patriot’s matching contributions during the six months ended November 30, 2011 and 2010 were $8,766 and $5,407, respectively. PDSG does not match participant voluntary contributions.

Guarantees and Indemnities

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 and California for PDSG. In connection with our facility leases, we have indemnified our lessors for certain claims arising from the use of the facilities. 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 condensed consolidated balance sheets.

Bonuses

During fiscal 2011, a retention bonus program was implemented to be paid to individuals who remain with PDSG until February 29, 2012. The projected liability for such bonuses was $90,000. This liability was being accrued ratably over the retention period. In November 2011, the retention bonus program was rescinded and replaced with an incentive bonus program for PDSG employees. Under the terms of the new bonus program the employees are eligible for a bonus if PDSG is acquired and the employees are retained by an acquirer or severance payments in the event PDSG employees are not retained by an acquirer. As we are unable to determine the outcome of PDSG we have not recorded a liability for the bonus program or severance payments.

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 2,844,630 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 the 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.

11. Subsequent Events

During the period December 1, 2011 through January 9, 2012, we purchased 552,016 shares of our common stock at an aggregate cost of $28,985 pursuant to our stock buyback program.

In December 2011 we received $40,054 from Deutsche Bank relating to partial redemptions of auction rate securities occurring on December 1, 2011. Such amount is a recovery on the $648,740 realized loss on sale of marketable securities recognized during the quarter ended August 31, 2010. Deutsche Bank had repurchased our illiquid auction rate securities pursuant to our settlement agreement with them in September 2010.

On December 14, 2011, we contributed $200,000 to PDS following a determination by PDS’ management committee that additional funds were required so that PDS could fund the initial installment of a legal retainer payable to newly engaged IP counsel. In connection with our contribution, TPL forfeited rights to $200,000 of special litigation support payments due it pursuant to the October 6, 2011 settlement agreement. The forfeited right will be treated as an in-kind capital contribution of $200,000.

During December 2011, we renewed the PDSG lease of Suite 100 through March 2012 at $11,028 per month.

On January 4, 2012 we received a federal tax refund of $421,937.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

THE FOLLOWING DISCUSSION AND THE REST OF THIS QUARTERLY REPORT ON FORM 10-Q INCLUDES FORWARD-LOOKING STATEMENTS WITH RESPECT TO OUR FUTURE FINANCIAL PERFORMANCE. ACTUAL RESULTS MAY DIFFER MATERIALLY FROM THOSE CURRENTLY ANTICIPATED AND FROM HISTORICAL RESULTS DEPENDING UPON A VARIETY OF FACTORS, INCLUDING THOSE DESCRIBED BELOW UNDER THE SUB-HEADING, "RISK FACTORS". SEE ALSO OUR ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED MAY 31, 2011.

Overview

In June 2005, we entered into a series of agreements with TPL and others to facilitate the pursuit of unlicensed users of our intellectual property. In October 2011 we settled litigation with TPL that was initiated by us over matters related to the management of the MMP Portfolio. We intend to continue our joint venture with TPL to pursue license agreements with unlicensed users of our technology. We believe that continuing to work through TPL, as compared to pursuing other alternatives, including creating and using our own licensing team for those activities, avoids a competitive devaluation of our principal assets and is a prudent way to achieve the desired results as we seek to obtain fair value from users of our intellectual property.

On October 5, 2009, we announced a reorganization of PDSG and our management. On January 25, 2010, we sold the Iameter assets and during August 2010, we sold the Vigilys business line. As a result of our reorganization and PDSG’s continued inability to meet its business plan, we have incurred impairment charges for our intangibles and goodwill in the PDSG segment of our business. On July 28, 2011, PDSG announced new business initiatives including Software as a Service offerings aimed at providing alternative methods to generate new revenues. We continue to fund the day to day operating costs of PDSG. Our merger and acquisition activities have ceased since our October 2009 reorganization.

Cash shortfalls and liquidity issues currently experienced by PDS and continued negative cash flows incurred by PDSG will have an adverse effect on our liquidity. Accordingly, we have and may continue to examine alternatives that could allow for the partnering or divestiture of PDSG. During October 2011, we retained an investment banker to seek a buyer for PDSG although given the operational history of PDSG to date there can be no guarantee that a divestiture will result in the realization of material consideration. With respect to PDS and TPL, we do not have any contractual commitments to fund any cash requirements of these entities.

On January 9, 2012 PDS’ cash balance is $314,388. Management’s plans for the continued operation of PDS rely on the ability of TPL to obtain license agreements to cover the operational costs of PDS. PDS has experienced a decline in licensing revenues and has experienced an increase in legal costs due to the patent litigation actions currently in progress. In the event that TPL cannot obtain license agreements to cover the operational costs of PDS, we and TPL must decide whether to fund PDS’ legal costs on a go forward basis.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which require us to make estimates and judgments that significantly affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates, and such differences could affect the results of operations reported in future periods. We believe the following critical accounting policies affect our most significant estimates and judgments used in the preparation of our consolidated financial statements.

1. Investments in Marketable Securities

2. Investment in Affiliated Company

We have a 50% interest in Phoenix Digital Solutions, LLC (“PDS”). We account for our investment using the equity method of accounting since the investment provides us the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if we have an ownership interest in the voting stock of the investee of between 20% and 50%, although other factors, such as representation on the investee’s Board of Directors, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting, the investment, originally recorded at cost, is adjusted to recognize our share of net earnings or losses of the investee and is recognized in the condensed consolidated statements of operations in the caption “Equity in loss of affiliated company.” and also is adjusted by contributions to and distributions from PDS.

During the six months ended November 30, 2011, our share of loss in PDS exceeds our investment in PDS by $2,017,797. We presently do not have a contractual obligation to fund any cash requirements of PDS and accordingly we have not recorded the excess loss on our consolidated financial statements, which is a change in our policy of accounting for PDS. Under the equity method of accounting, we are to continue to report losses up to our carrying amount of the investment. Once the investment balance is reduced to $0, we are to discontinue applying the equity method until such time that our share of future net income reported by PDS equals our share of net losses not recognized during the period the equity method was suspended.

We review our investment in an affiliated company to determine whether events or changes in circumstances indicate that the carrying amount may not be recoverable. The primary factors we consider in our determination are the financial condition, operating performance and near term prospects of the investee. If the decline in value is deemed to be other than temporary, we would recognize an impairment loss.

3. Revenue Recognition

4. Research and Development

Research and development costs are expensed as incurred and primarily include payroll and related benefit costs and contractor fees.

5. Share-Based Compensation

Share-based compensation expense recognized during the period is based on the grant date fair value of the portion of share-based payment awards ultimately expected to vest during the period . As share-based compensation expense recognized in the consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeiture rates are based on historical forfeiture experience and estimated future employee forfeitures.

PDSG

Revenue consisting of software licenses and associated services relating to PDSG’s CDX product decreased from approximately $73,000 for the three months ended November 30, 2010 to approximately $48,000 for the three months ended November 30, 2011. The decrease was primarily due to the level of activity and progress towards completion rendered on one time contracts that vary in size and scope depending upon the requirements of the customer. Cost of sales includes the direct time of PDSG employees on each project. Included in cost of sales is approximately $68,900 of amortization expense on purchased intangible assets for the three months ended November 30, 2010. Profit margin excluding amortization decreased for the three months ended November 30, 2011 as compared to the three months ended November 30, 2010 due to a greater portion of service revenue generated in the current period as compared to the prior period. During fiscal 2011, we wrote off PDSG’s remaining balance of purchased intangible assets.

PDSG

Research and development costs consist of PDSG’s payroll and related expenses for software engineers. The primary decreases in research and development costs for the three months ended November 30, 2011 as compared to November 30, 2010 were approximately $2,500 in outside contractor costs due to completion of CDX4 and approximately $4,000 in salaries and related costs due to management’s restructuring plan implemented in October of 2009. For the three months ended November 30, 2011 and 2010, approximately $500 and $500, respectively, of share-based compensation was recorded in connection with vesting of employee stock options.

PDSG

Selling, general and administrative expenses decreased from approximately $266,000 for the three months ended November 30, 2010 to approximately $214,000 for the three months ended November 30, 2011, due to management’s restructuring plan to reduce expenses. Decreases consisted primarily of approximately $45,000 in salaries and related expenses and approximately $13,000 in rent expenses due to the sublease of Suite 102. For the three months ended November 30, 2011 and 2010, approximately $4,500 and $4,500, respectively, of share-based compensation was recorded in connection with vesting of employee stock options.

PTSC

Selling, general and administrative expenses decreased from approximately $675,000 for the three months ended November 30, 2010 to approximately $451,000 for the three months ended November 30, 2011. The decrease consisted primarily of approximately $68,000 in legal fees, approximately $58,000 in consulting fees due to the termination of the services of Attain, and approximately $44,000 in board of directors’ fees due to fewer directors serving on our board during the current year period. For the three months ended November 30, 2010, approximately $3,000 of share-based compensation was recorded in connection with vesting of employee stock options.

Consolidated

Selling, general and administrative expenses decreased from approximately $940,000 for the three months ended November 30, 2010 to approximately $666,000 for the three months ended November 30, 2011 primarily due to continued cost reductions implemented by management.

Impairment of goodwill	$	-	$	642,981

PDSG

Management’s plan of restructuring on October 5, 2009 and the continuing inability of PDSG to meet its business plan were indicators of potential impairment on our goodwill. Accordingly, at November 30, 2010, management determined that goodwill was impaired by approximately $643,000.

PDSG

Operating loss decreased from approximately $1,067,000 for the three months ended November 30, 2010 to approximately $330,000 for the three months ended November 30, 2011 primarily due to the lack of goodwill impairment in the current fiscal year and decreases in operating expenses as management continued to implement cost reductions.

PTSC

Operating loss decreased from approximately $675,000 for the three months ended November 30, 2010 to approximately $451,000 for the three months ended November 30, 2011 due to decreases in operating expenses for legal, consulting and board fees.

Consolidated

Our other income and expenses for the three months ended November 30, 2011 and 2010 included equity in the loss of PDS of approximately $227,000 and $316,000, respectively. Our investment in PDS is accounted for in accordance with the equity method of accounting for investments, accordingly we will only record income to the extent PDS eliminates accumulated losses and after basis in our investment is zero we will only record losses to the extent that we advance or contribute funds to PDS.

PDSG

Loss before income taxes decreased from approximately $1,067,000 for the three months ended November 30, 2010 to approximately $330,000 for the three months ended November 30, 2011 primarily due to the lack of goodwill impairment in the current fiscal year and decreases in operating expenses as management continued to implement cost reduction measures.

PTSC

Loss before income taxes decreased from approximately $995,000 for the three months ended November 30, 2010 to approximately $673,000 for the three months ended November 30, 2011 primarily due to our inability to recognize our losses from PDS during the three months ended November 30, 2011 as our losses have exceeded the cost basis of our investment.

During the three months ended November 30, 2011, we recorded a provision for income taxes related to California taxes of $1,600.

During the three months ended November 30, 2010, we recorded a benefit for income taxes of approximately $562,000 related to federal and California taxes.

Net loss

We recorded a net loss for the three months ended November 30, 2011 and 2010 of $1,004,482 and $1,499,530, respectively.

PDSG

Revenue consisting of software licenses and associated services relating to PDSG’s CDX product increased from approximately $167,000 for the six months ended November 30, 2010 to approximately $182,000 for the six months ended November 30, 2011. The increase was primarily due to the level of activity and progress towards completion rendered on one time contracts that vary in size and scope depending upon the requirements of the customer. Cost of sales includes the direct time of PDSG employees on each project. Profit margin excluding amortization decreased for the six months ended November 30, 2011 as compared to the six months ended November 30, 2010 due to a greater portion of service revenue generated in the current period as compared to the prior period. Included in cost of sales is approximately $138,000 of amortization expense on purchased intangible assets for the six months ended November 30, 2010. During fiscal 2011, we wrote off PDSG’s remaining balance of purchased intangible assets.

PDSG

Selling, general and administrative expenses decreased from approximately $637,000 for the six months ended November 30, 2010 to approximately $479,000 for the six months ended November 30, 2011, due to management’s restructuring plan to reduce expenses. Decreases consisted primarily of approximately $106,000 in salaries and related expenses and approximately $22,000 in rent expenses due to the sublease of Suite 102. For the six months ended November 30, 2011 and 2010, approximately $9,000 and $9,400, respectively, of share-based compensation was recorded in connection with vesting of employee stock options.

PTSC

Selling, general and administrative expenses decreased from approximately $1,659,000 for the six months ended November 30, 2010 to approximately $923,000 for the six months ended November 30, 2011. The decrease consisted primarily of approximately $341,000 in legal fees due to the settlement of the Deutsche Bank matter and the settlement of one of the TPL actions, approximately $176,000 in consulting fees due to the termination of the services of Attain, approximately $89,000 in board of directors’ fees due to fewer directors serving on our board during the current year period and approximately $24,000 in rent expense. For the six months ended November 30, 2010, approximately $56,000 of share-based compensation was recorded in connection with vesting of employee stock options.

Since the quarter ended August 31, 2011 we have not been able to fully recognize our losses in PDS as the losses have exceeded our cost basis in the investment. Our investment in PDS is accounted for in accordance with the equity method of accounting for investments. During the six months ended November 30, 2010, we recorded a gain on the sale of the Vigilys business line of $60,000. During the six months ended November 30, 2010, we realized a loss on our ARS of $648,740 according to terms of our confidential settlement agreement with Deutsche Bank.

Loss before income taxes decreased from approximately $1,607,000 for the six months ended November 30, 2010 to approximately $663,000 for the six months ended November 30, 2011 primarily due to the lack of goodwill impairment in the current fiscal year and decreases in operating expenses as management continued to implement cost reduction measures.

PTSC

Loss before income taxes decreased from approximately $3,786,000 for the six months ended November 30, 2010 to approximately $1,403,000 for the six months ended November 30, 2011 primarily due to our inability to recognize our losses from PDS during the three months ended November 30, 2011 as our losses have exceeded the cost basis of our investment and decreases in legal, consulting and other operating expenses.

Provision (benefit) for income taxes

During the six months ended November 30, 2011, we recorded a provision for income taxes related to California taxes of $3,200.

During the six months ended November 30, 2010, we recorded a benefit for income taxes of approximately $1,893,000 related to federal and California taxes.

Net loss

We recorded a net loss for the six months ended November 30, 2011 and 2010 of $2,068,451 and $3,499,930, respectively.

Liquidity and Capital Resources

Liquidity

Our cash and short-term investment balances decreased from approximately $10,661,000 as of May 31, 2011 to approximately $8,976,000 as of November 30, 2011. We also have restricted cash balances amounting to approximately $21,000 as of May 31, 2011 and November 30, 2011. Total current assets decreased from approximately $12,196,000 as of May 31, 2011 to approximately $9,806,000 as of November 30, 2011. Total current liabilities amounted to approximately $576,000 and approximately $227,000 as of May 31, 2011 and November 30, 2011, respectively.

The cost of accessing the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards, and reduced or ceased to provide funding to borrowers. Adverse changes in the economy could limit our ability to obtain financing from debt or equity sources or could adversely affect the terms on which we may be able to obtain any such financing.

Cash shortfalls currently experienced by PDS and continued negative cash flows incurred by PDSG will have an adverse effect on our liquidity. Accordingly, we have and may continue to examine alternatives that could allow for the partnering or divestiture of PDSG. If successful, these measures may provide for a further reduction in expenses and cash use, or additionally in the event of divestiture, cash proceeds, although given the operational history of PDSG to date there can be no guarantee that a divestiture will result in the realization of material consideration. With respect to PDS and TPL, we do not have any contractual commitments to fund any cash requirements of these entities.

Cash Flows From Operating Activities

Cash used in operating activities was approximately $1,375,000 and $2,739,000 for the six months ended November 30, 2011 and 2010, respectively. The principal components of the current period amount were: loss in earnings of affiliated company of approximately $528,000, and prepaid income taxes of approximately $403,000. These increases were offset by: net loss of approximately $2,068,000, and changes in accounts payable and accrued expenses of approximately $314,000. The principal components of the prior period are the prior period net loss and the change in deferred income taxes offset by the: realized loss on sale of marketable securities, impairment of goodwill and equity in loss of affiliated company.

Cash Flows From Investing Activities

Cash used in investing activities was approximately $1,324,000 for the six months ended November 30, 2011 as compared to cash provided by investing activities of approximately $6,041,000 for the six months ended November 30, 2010. We received no distributions from PDS for the six months ended November 30, 2011 and 2010. Cash activities for the current period were attributable to purchases and sales of marketable securities and cash received for repayment of a note receivable during the six months ended November 30, 2010.

Cash Flows From Financing Activities

Cash used in financing activities for the six months ended November 30, 2011 and 2010 was approximately $66,000 and $3,221,000, respectively. For the six months ended November 30, 2011 and 2010, cash of approximately $66,000 and $97,000 was used to purchase common stock for treasury. For the six months ended November 30, 2010 cash of approximately $3,122,000 was used to repay our note with Wedbush.

Capital Resources

While our current liquid cash resources as of November 30, 2011, are expected to provide the funds necessary to support our operations through at least the next twelve months assuming we do not continue to fund the obligations of PDS. The cash flows from our interest in PDS represent our primary significant source of cash generation. In the event of a continued decrease or interruption in MMP Portfolio licensing we will incur a significant reduction to our cash position as the revenues from our PDSG subsidiary are insufficient to cover the costs of its operations and the costs of Patriot Scientific Corporation as a whole. It is highly unlikely that we would be able to obtain any additional sources of financing to supplement our cash and short-term investment position of $8,975,788 at November 30, 2011.

In December 2011, TPL engaged new counsel on behalf of PDS, and committed PDS to paying an initial retainer payable in monthly installments. The $200,000 that we contributed to PDS referred to above, was used to pay the first installment of such retainer. The remaining balance of the retainer is anticipated to be funded by PDS from licensing revenues. In the event that PDS does not have the funds to pay one or more installments of the retainer, we and TPL must decide whether to contribute additional capital to PDS to fund such installments. The newly retained counsel will continue the Northern California cases to trial after the claims construction hearing.

Recent Accounting Pronouncements

During the six months ended November 30, 2011, there were no recent issuances of accounting pronouncements as compared to those described in our Annual Report on Form 10-K for the fiscal year ended May 31, 2011, that are of significance, or have potential material significance to us.

Risk Factors

We urge you to carefully consider the following discussion of risks as well as other information regarding our common stock. We believe the following to be our most significant risk factors as of the date this report is being filed. The risks and uncertainties described below are not the only ones we face. Please refer to our risk factors contained in our Form 10-K for the year ended May 31, 2011 for additional risk factors.

We Have Reported Licensing Income In Prior Fiscal Years Which May Not Be Indicative Of Our Future Income.

We have entered into license agreements through our joint venture with TPL and have reported licensing income as a result of this activity for the fiscal years 2006 to 2011. Because of the uncertain nature of the negotiations that lead to license revenues, pending litigation with companies which we allege have infringed on our patent portfolio, the possibility of legislative action regarding patent rights, potential adverse outcomes associated with the U. S. Patent and Trademark Office (“USPTO”) re-examinations, the litigation initiated by an inventor of the microprocessor portfolio with TPL, and the possible effect of new judicial interpretations of patent laws, we may not receive revenues from such agreements in the future consistent with amounts received in the past, and we may not receive future revenues from license agreements at all.

We Are Dependent Upon A Joint Venture In Which Our Role Is Of A Passive Nature For Substantially All Of Our Income.

In June 2005, we entered into a joint venture with TPL, pursuant to which TPL is responsible for the licensing and enforcement of our microprocessor patent portfolio. This joint venture has been the source of substantially all of our income since June 2005. Therefore, in light of the absence of significant revenue from other sources, we should be regarded as entirely dependent on the success or failure of the licensing and prosecution efforts of TPL on behalf of the joint venture, and the ability of TPL to obtain capital when necessary to fund its operations. We do not anticipate making additional loans to TPL, and its ability to access liquidity from other sources is not certain.

Our Joint Venture Is At Risk For Going Concern And An Inability To Meet Certain Obligations.

PDS, our joint venture with TPL, which received a going concern opinion in our May 31, 2011 financial statements, has experienced significant declines in revenues while at the same time incurring significant legal costs associated with pending litigation with companies which we allege have infringed on our patent portfolio. Currently, there are no commitments by us or TPL to provide additional working capital to PDS. We expect PDS will fund its operations through licensing revenue.

In December 2011, TPL engaged new counsel on behalf of PDS, and committed PDS to paying an initial retainer payable in monthly installments. The $200,000 that we contributed to PDS referred to above, was used to pay the first installment of such retainer. The remaining balance of the retainer is anticipated to be funded by PDS from licensing revenues, which have declined over recent years to a point where PDS’ ability to make the foregoing retainer payments is in substantial doubt unless licensing revenues substantially increases in the near term.

In the event that PDS does not have the funds to pay one or more installments of the retainer, we and TPL must decide whether to contribute additional capital to PDS to fund such installments. The newly retained counsel will continue the Northern California cases to trial after the claims construction hearing.

A Successful Challenge To Our Intellectual Property Rights Could Have A Significant And Adverse Effect On Us.

A successful challenge to our ownership of our technology or the proprietary nature of our intellectual property could materially damage our business prospects. We rely on a combination of patents, trademarks, copyrights, trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights. With respect to our core technologies, we currently have seven U.S. patents, one European patent, and one Japanese patent issued. Any issued patent may be challenged and invalidated. Patents may not be issued for any of our pending applications. Any claims allowed from existing or pending patents may not be of sufficient scope or strength to provide significant protection for our products. Patents may not be issued in all countries where our products can be sold so as to provide meaningful protection or any commercial advantage to us. Our competitors may also be able to design around our patents.

Vigorous protection and pursuit of intellectual property rights or positions characterize the fiercely competitive semiconductor industry, which has resulted in significant and often protracted and expensive litigation. Therefore, our competitors and others may assert that our technologies or products infringe on their patents or proprietary rights. Persons we believe are infringing our patents are likely to vigorously defend their actions and assert that our patents are invalid. Problems with patents or other rights could result in significant costs, limit future license revenue, and impair or hinder our acquisition strategy. If infringement claims against us are deemed valid or if our infringement claims are successfully opposed, we may not be able to obtain appropriate licenses on acceptable terms or at all. Litigation could be costly and time-consuming but may be necessary to protect our future patent and/or technology license positions or to defend against infringement claims. From time to time parties have petitioned the USPTO to re-examine certain of our patents. An adverse decision in litigation or in the re-examination process could have a very significant and adverse effect on our business.

We have been named as co-defendants in multiple lawsuits regarding the MMP Portfolio. See footnote 9 to our condensed consolidated financial statements and Part II, Item 1. “Legal Proceedings” in this quarterly report on Form 10-Q for more information.

In the event that one or more of these lawsuits regarding the MMP Portfolio are not resolved in our favor, such outcome (or lack of an outcome) could weaken the MMP Portfolio which would have a negative affect on PDS's ability to procure future license revenues and, therefore, adversely affect PDS's and our cash flows.

Our Wholly-Owned Subsidiary Cannot Operate Without Our Continued Support.

Since the acquisition of our wholly-owned subsidiary PDSG in September 2008, we have provided 100% of PDSG’s operational funding amounting to approximately $8,850,000 through November 30, 2011. After restructuring measures initiated in October 2009 and continued through November 30, 2011, PDSG continues to remain unable to generate sufficient revenues to support its operations and remains entirely dependent on our funding. During October 2011, PTSC retained the services of an investment banker to seek a buyer for PDSG. Should a sale of PDSG occur, it may be on distressed terms with only minimal consideration realized.

Disruptions In The Debt And Equity Markets Will Have An Adverse Affect On Our Ability To Obtain Funding.

The debt and equity markets have been experiencing volatility and disruption for several fiscal periods. These issues, along with significant write-offs in the financial services sector, the re-pricing of credit risk, and the current weak economic conditions have made, and will likely continue to make, it difficult to obtain funding. The cost of accessing the credit markets has increased as many lenders and institutional investors have increased interest rates, enacted tighter lending standards, and reduced or ceased to provide funding to borrowers. Adverse changes in the economy could limit our ability to obtain financing from debt or equity sources or could adversely affect the terms on which we may be able to obtain any such financing for our operating activities. See Part I – Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources-Liquidity.” in this quarterly report on Form 10-Q for more information.

Unstable Market And Economic Conditions May Have Serious Adverse Consequences On Our Business .

Our general business strategy may be adversely affected by the recent economic downturn and volatile business environment and continued unpredictable and unstable market conditions. A prolonged or profound economic downturn may result in adverse changes to our sales and pricing, which would harm our operating results. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon development plans. There is also a possibility that our stock price may decline further, due in part to the volatility of the stock market and the general economic downturn.

Changes In Our Relationships With Companies In Which We Hold Less Than A Majority Interest Could Change The Way We Account For Such Interests In The Future.

For our investment accounted for under the equity method (PDS), we record as part of other income or expense our share of the increase or decrease in the equity of this company in which we have invested. It is possible that, in the future, our relationships and/or our interests in or with this equity method investee could change. Such potential future changes could result in consolidation of such entity which could result in changes in our reported results.

If A Large Number Of Our Shares Are Sold All At Once Or In Blocks, The Market Price Of Our Shares Would Most Likely Decline.

Most of our shareholders are not restricted in the price at which they can sell their shares. Shares sold at a price below the current market price at which our Common Stock is trading may cause the market price of our Common Stock to decline.

The Market For Our Stock Is Subject To Rules Relating To Low-Priced Stock (“Penny Stock”) Which May Limit Our Ability To Raise Capital.

Our Common Stock is currently listed for trading in the OTCQB operated by OTC Markets, Inc. and is subject to the “penny stock rules” adopted pursuant to Section 15(g) of the Exchange Act. In general, the penny stock rules apply to non-NASDAQ or non-national stock exchange companies whose common stock trades at less than $5.00 per share or which have tangible net worth of less than $5,000,000 ($2,000,000 if the company has been operating for three or more years). Such rules require, among other things, that brokers who trade “penny stock” on behalf of persons other than “established customers” complete certain documentation, make suitability inquiries of investors and provide investors with certain information concerning trading in the security, including a risk disclosure document, quote information, broker’s commission information and rights and remedies available to investors in penny stocks. Many brokers have decided not to trade “penny stock” because of the requirements of the penny stock rules, and as a result, the number of broker-dealers willing to act as market makers in such securities is limited. The “penny stock rules,” therefore, may have an adverse impact on the market for our Common Stock and may affect our ability to raise additional capital if we decide to do so.

Our Share Price Could Decline As A Result Of Short Sales.

When an investor sells stock that he does not own, it is known as a short sale. The seller, anticipating that the price of the stock will go down, intends to buy stock to cover his sale at a later date. If the price of the stock goes down, the seller will profit to the extent of the difference between the price at which he originally sold it less his later purchase price. Short sales enable the seller to profit in a down market. Short sales could place significant downward pressure on the price of our Common Stock. Penny stocks which do not trade on an exchange, such as our Common Stock, are particularly susceptible to short sales.

Our Future Success Depends In Significant Part Upon The Continued Services Of Our Key Senior Management.

Our future success depends in significant part upon the continued services of our key senior management personnel. The competition for highly qualified personnel is intense, and we may not be able to retain our key managerial employees or attract and retain additional highly qualified technical and managerial personnel in the future. None of our employees are represented by a labor union, and we consider our relations with our employees to be good. None of our employees are covered by key man life insurance policies

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Item 4. Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, as of November 30, 2011, the end of the period to which this quarterly report relates, we have carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. This evaluation was carried out under the supervision and with the participation of our management, including our Interim Chief Executive Officer and our Chief Financial Officer.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including the Interim Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of November 30, 2011, our management, with the participation of our Interim Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no significant changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
