Refer to Note 7 for a description of the acquisition transaction.
 
Other

In January 2006, Acacia Research Corporation’s board of directors approved a plan for its wholly owned subsidiary, CombiMatrix Corporation, to become an independent public company. The transaction is expected to be completed no sooner than the fourth quarter of 2006, subject, however, to determination that there are no significant negative tax consequences to Acacia Research Corporation or it’s shareholders and completing the required filings with the Securities and Exchange Commission, or SEC. We have requested a private letter ruling from the IRS and intend to proceed only after receiving the ruling. If the conditions are met, Acacia Research Corporation will redeem all of the issued and outstanding shares of AR-CombiMatrix common stock for all of the common stock of CombiMatrix Corporation, which will register its common stock under the Securities and Exchange Act of 1934. Following the redemption, CombiMatrix Corporation will apply to list its shares for trading on a national exchange.

Capital Structure. On December 11, 2002, our stockholders voted in favor of a recapitalization transaction, which became effective on December 13, 2002, whereby we created two new classes of common stock called Acacia Research-CombiMatrix common stock (“AR-CombiMatrix stock”) and Acacia Research-Acacia Technologies common stock (“AR-Acacia Technologies stock”), and divided our existing Acacia Research Corporation common stock into shares of the two new classes of common stock. AR-CombiMatrix stock is intended to reflect separately the performance of Acacia Research Corporation’s CombiMatrix group. AR-Acacia Technologies stock is intended to reflect separately the performance of Acacia Research Corporation’s Acacia Technologies group. Although the AR-CombiMatrix stock and the AR-Acacia Technologies stock are intended to reflect the performance of our different business groups, they are both classes of common stock of Acacia Research Corporation and are not stock issued by the respective groups.

Liquidity and Risks

General. To date, we and our subsidiaries have relied primarily upon selling equity securities and payments from our strategic partners and licensees to generate the funds needed to finance the implementation of our plans of operation for our subsidiaries. Management believes that our cash and cash equivalent balances, anticipated cash flow from operations and other external sources of available credit will be sufficient to meet our cash requirements through at least September 30, 2007. We may be required to obtain additional financing. There can be no assurance that additional funding will be available on favorable terms, if at all. If we fail to obtain additional funding when needed, we may not be able to execute our business plans and our businesses may suffer.

The CombiMatrix Group. The CombiMatrix group is deploying new and unproven technologies and continues to develop its commercial products. The CombiMatrix group has several ongoing long-term development projects that involve experimental technology and may require several years and substantial expenditures to complete. Management believes that existing cash and cash equivalents and short-term investments are adequate to fund operations through at least September 30, 2007 (see Note 6 for standby equity distribution agreement entered into in June 2006). However, the ability to meet business objectives is dependent upon the CombiMatrix group’s ability to raise additional financing, substantiate its technology and ultimately to fund itself from continuing operations. There can be no assurance that such funding will be available at acceptable terms or at all. The CombiMatrix group has a history of incurring net losses and net operating cash flow deficits.

The CombiMatrix group’s business operations are also subject to certain risks and uncertainties, including:
 
·
market acceptance of products and services;
·
technological advances that may make its products and services obsolete or less competitive;
·
increases in operating costs, including costs for supplies, personnel and equipment;
·
the availability and cost of capital; and
·
governmental regulation that may restrict its business.

Historically, the CombiMatrix group has been substantially dependent on arrangements with strategic partners and has relied upon payments by its partners for a significant component of its working capital. The CombiMatrix group intends to enter into additional strategic partnerships to develop and commercialize future products. However, there can be no assurance that the CombiMatrix group will be able to implement its future plans. Failure to achieve its plans would have a material adverse effect on the CombiMatrix group’s and on Acacia Research Corporation’s ability to achieve their intended business objectives. The CombiMatrix group also depends on its ability to protect its intellectual property; the loss thereof or the CombiMatrix group’s failure to secure the issuance of additional patents covering elements of its business processes could materially harm its business and financial condition. The patents covering the CombiMatrix group’s core technology begin to expire in 2018.

The CombiMatrix group’s products and services are concentrated in a highly competitive market that is characterized by rapid technological advances, frequent changes in customer requirements and evolving regulatory requirements and industry standards. Failure to anticipate or respond adequately to technological advances, changes in customer requirements, changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of planned products or services, could have a material adverse effect on the CombiMatrix group’s business and operating results.

The Acacia Technologies Group. To date, the Acacia Technologies group has relied upon the receipt of license fee payments from the licensing of the Acacia Technologies group’s patented technologies and the selling of Acacia Research Corporation equity securities to generate the funds needed to finance the operations of the Acacia Technologies group. The Acacia Technologies group began to commercially license its DMT® technology in 2003. The GPH Acquisition provided the Acacia Technologies group with ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and cover technologies used in a wide variety of industries. The GPH Acquisition, and other patent acquisitions during 2005 and 2006, continue to expand and diversify the Acacia Technologies group’s future potential revenue generating activities.

There can be no assurance that the Acacia Technologies group will be able to implement its future plans. Failure by management to achieve its plans would have a material adverse effect on the Acacia Technologies group and on Acacia Research Corporation’s ability to achieve its intended business objectives. The Acacia Technologies group’s success also depends on its ability to protect its intellectual property.
 
The timing of the receipt of revenues by the Acacia Technologies group’s business operations are subject to certain risks and uncertainties, including:

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

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

Basis of Presentation. The accompanying unaudited consolidated financial statements include the accounts of Acacia Research Corporation and its wholly owned and majority-owned subsidiaries and investments accounted for under the equity method. Material intercompany transactions and balances have been eliminated in consolidation.

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and footnotes required by generally accepted accounting principles in annual financial statements have been omitted or condensed in accordance with quarterly reporting requirements of the SEC. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2005, as reported by us in our Annual Report on Form 10-K. The year-end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America.

ACACIA RESEARCH CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

The consolidated financial statements of Acacia Research Corporation include all adjustments of a normal recurring nature which, in the opinion of management, are necessary for a fair statement of our financial position as of June 30, 2006, and results of operations and cash flows for the interim periods presented. The results of operations for the three and six months ended June 30, 2006, are not necessarily indicative of the results to be expected for the entire year.

Separate Group Presentation. AR-CombiMatrix stock and AR-Acacia Technologies stock are intended to reflect the separate performance of the respective division of Acacia Research Corporation. The CombiMatrix group and the Acacia Technologies group are not separate legal entities. Holders of AR-CombiMatrix stock and AR-Acacia Technologies stock are stockholders of Acacia Research Corporation. As a result, holders of AR-CombiMatrix stock and AR-Acacia Technologies stock continue to be subject to all of the risks of an investment in Acacia Research Corporation and all of its businesses, assets and liabilities. The assets Acacia Research Corporation attributes to one of the groups could be subject to the liabilities of the other group. The group financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, and taken together, comprise all the accounts included in the corresponding consolidated financial statements of Acacia Research Corporation. The financial statements of the groups reflect the financial position, results of operations, and cash flows of the businesses included therein. The financial statements of the groups include the accounts or assets of Acacia Research Corporation specifically attributed to the groups and were prepared using amounts included in Acacia Research Corporation’s consolidated financial statements.
 
Minority interests represent participation of other stockholders in the net equity and in the division earnings and losses of the groups and are reflected in the caption “Minority interests” in the group financial statements. Minority interests adjust group net results of operations to reflect only the group’s share of the division earnings or losses of non-wholly owned investees.  
 
Financial effects arising from one group that affect Acacia Research Corporation’s results of operations or financial condition could, if significant, affect the results of operations or financial condition of the other group and the market price of the class of common stock relating to the other group. Any division net losses of the CombiMatrix group or of the Acacia Technologies group, and dividends or distributions on, or repurchases of, AR-CombiMatrix stock or AR-Acacia Technologies stock, will reduce the assets of Acacia Research Corporation legally available for payment of dividends on AR-CombiMatrix stock or AR-Acacia Technologies stock.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Revision in the Classification of Certain Securities. In connection with the preparation of the 2005 consolidated financial statements, Acacia Research Corporation concluded that it was appropriate to classify its annuity investments as current investments.  Prior to 2005, such investments had been classified as cash and cash equivalents. Accordingly, we have made adjustments to our consolidated statement of cash flows for the six months ended June 30, 2005, to reflect the gross purchases of these securities as investing activities rather than as a component of cash and cash equivalents.  This change in classification does not affect previously reported cash flows from operations or from financing activities in our previously reported statements of cash flows, and it does not affect our previously reported statements of operations for any period.

As of June 30, 2005, before this revision in classification, $4,896,000 of these current investments were classified as cash and cash equivalents on our consolidated balance sheet.  There were no material purchases or sales of annuity investments during any of the periods presented, as such, the impact of the revision in classification on consolidated cash flows from investing activities was not material for any of the periods presented.

Stock-Based Compensation. Effective January 1, 2006, Acacia Research Corporation adopted the provisions of Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123R”), which sets forth the accounting requirements for “share-based” compensation payments to employees and non-employee directors and requires that compensation cost relating to share-based payment transactions be recognized in the statement of operations. In March 2005, the SEC published Staff Accounting Bulletin No. 107 (“SAB 107”), which requires stock-based compensation to be classified in the same expense line items as cash compensation (i.e. marketing, general and administrative and research and development expenses). The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity award).

7

ACACIA RESEARCH CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

In addition, SFAS No. 123R requires stock-based compensation expense to be recorded only for those awards expected to vest using an estimated forfeiture rate. As such, SFAS No. 123R requires Acacia Research Corporation to estimate pre-vesting option forfeitures at the time of grant and reflect the impact of estimated pre-vesting option forfeitures on compensation expense recognized. Acacia Research Corporation considers several factors in connection with our estimates of pre-vesting forfeitures including types of awards, employee classification, and historical pre-vesting forfeiture data. Estimates of pre-vesting forfeitures must be periodically revised in subsequent periods if actual forfeitures differ from those estimates. To the extent that actual results differ from our estimates, such amounts will be recorded as cumulative adjustments in the period the estimates are revised. Prior to the adoption of SFAS No. 123R, Acacia Research Corporation accounted for forfeitures as they occurred under the pro forma disclosure provisions of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation.” All references to stock-based compensation expense in these notes, upon adoption of SFAS No. 123R, refers to stock-based compensation net of estimated forfeitures, as required by SFAS No. 123R.
 
We adopted SFAS No. 123R using the modified prospective transition method. Under this transition method, compensation cost recognized for the six months ended June 30, 2006 includes: (i) compensation cost for all stock-based awards granted prior to, but not yet vested as of January 1, 2006 (based on the grant-date fair value estimated in accordance with the original provisions of SFAS No. 123 and previously presented in the pro forma footnote disclosures), and (ii) compensation cost for all stock-based awards granted subsequent to January 1, 2006 (based on the grant-date fair value estimated in accordance with the new provisions of SFAS No. 123R). The cumulative effect of applying an estimated forfeiture percentage to stock-based payments granted prior to, but not yet vested as of, January 1, 2006 was not material.

Prior to January 1, 2006, Acacia Research Corporation accounted for share-based compensation to employees in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), and related interpretations. Acacia Research Corporation also followed the disclosure requirements of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”), as amended by Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure.” Because Acacia Research Corporation previously adopted only the pro forma disclosure provisions of SFAS No. 123, we will recognize compensation cost relating to the unvested portion of awards granted prior to the date of adoption using the same estimate of the grant-date fair value and the same attribution method used to determine the pro forma disclosures under SFAS No. 123, except that forfeiture rates will be estimated for all awards, as required by SFAS No. 123R. In accordance with the requirements of the modified prospective transition method of adoption of SFAS No. 123R, the financial statement amounts for prior periods presented in this Form 10-Q have not been restated to reflect the fair value method of recognizing compensation cost relating to stock-based awards.

The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model that uses the assumptions noted in the table below. Expected volatility is based on the separate historical volatility of the market prices of the AR-CombiMatrix stock and AR-Acacia Technologies stock. Volatilities of peer companies were also considered, when applicable, to address the lack of extensive historical volatility data for Acacia Research Corporation’s classes of common stock. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected term assumption was determined in accordance with guidance set forth in SAB 107, which provides a “simplified method” for estimating the expected term for stock options, granted prior to December 31, 2007, that 1) are granted at-the-money, 2) have exercisability conditioned only on completion of a service condition through the vesting date, 3) require that employees who terminate their service prior to vesting must forfeit the options, 4) provide that employees who terminate their service after vesting are granted limited time to exercise their stock options (typically 30-90 days), and 5) are nontransferable and nonhedgeable. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting commencement date and the expiration date is used as the expected term under this method. For awards with multiple vesting-tranches, the times from grant until these mid-points for each of the tranches were averaged to provide an overall expected term.

The fair value of restricted stock awards is determined by the product of the number of shares granted and the grant date market price of the AR-Acacia Technologies stock or AR-CombiMatrix stock.
 
The fair value of share-based awards is expensed on a straight-line basis over the requisite service period (generally the vesting period of the award), which is generally two to four years.

Stock-based compensation expense for the three and six months ended June 30, 2006 and 2005 is included in research and development expenses and marketing, general and administrative expenses, as disclosed in the accompanying consolidated statement of operations and comprehensive income (loss).
 
Awards granted prior to Acacia Research Corporation’s implementation of SFAS No. 123R were accounted for under the recognition and measurement principles of APB No. 25 and related interpretations. Accordingly, no stock-based employee compensation cost was reflected in net loss in the accompanying unaudited consolidated statements of operations for the three and six months ended June 30, 2005, because all options granted under Acacia Research Corporation’s plans had exercise prices equal to the market value of the underlying common stock on the date of grant.

(1)
The fair value of stock options was determined using the Black-Scholes option-pricing model. The fair value calculations assume no expected dividends.
(2)
The previously reported 2005 pro forma income (loss) from operations and related pro forma earnings (loss) per share amounts have been revised for a computational error in the amortization of stock compensation expense and to reflect amounts with a 0% effective tax rate due to the full valuation allowance recoded by the company for all periods presented and to exclude stock compensation expense related to non-employees.

SFAS No. 123R does not require the recording of deferred stock compensation charges in stockholder’s equity on the grant date of a stock based award. As such, in accordance with SFAS No. 123R, all deferred stock compensation charges recorded under APB No. 25, totaling $1,400,000 at December 31, 2005, have been reversed upon adoption of SFAS No. 123R, with a corresponding reduction being recorded in consolidated additional paid-in capital.

3. EARNINGS PER SHARE

Earnings Per Share. Basic earnings per share for each class of common stock is computed by dividing the income or loss allocated to each class of common stock by the weighted average number of outstanding shares of that class of common stock. Diluted earnings per share is computed by dividing the income allocated to each class of common stock by the weighted average number of outstanding shares of that class of common stock including the dilutive effect of potential common shares, computed using the treasury method. Potential common shares primarily consist of employee stock options and unvested restricted stock grants.

The earnings or losses allocated to each class of common stock are determined by Acacia Research Corporation’s board of directors. This determination is generally based on the net income or loss amounts of the corresponding group determined in accordance with accounting principles generally accepted in the United States of America. Acacia Research Corporation believes this method of allocation is systematic and reasonable. The Acacia Research Corporation board of directors can, at its discretion, change the method of allocating earnings or losses to each class of common stock at any time.

The Acacia Technologies group and the CombiMatrix group’s patents have remaining estimated economic useful lives up to 2013 and 2020, respectively. The weighted average remaining estimated economic useful life of the Acacia Technologies group’s patents is 5 years. The weighted average remaining estimated economic useful life of the CombiMatrix group’s patents is 9 years. Annual aggregate amortization expense for each of the five fiscal years through December 31, 2010 is estimated to be $5,272,000 in 2006, $5,235,000 in 2007, $3,912,000 in 2008, $3,461,000 in 2009 and $3,270,000 in 2010 for the Acacia Technologies group and $1,095,000 per year for the CombiMatrix group. At June 30, 2006, and December 31, 2005, all of our acquired intangible assets other than goodwill were subject to amortization.

For the six months ended June 30, 2006, the Acacia Technologies group incurred patent acquisition costs totaling $1,020,000 in connection with the acquisition of the rights to several additional patent portfolios. The acquired patents and patent rights have estimated economic useful lives ranging from five to seven years. Refer to Note 7 for additions to patent related intangibles during the six months ended June 30, 2005.

During the three months ended June 30, 2006, the Acacia Technologies group recorded a non-cash charge of $297,000, related to the write-off of a patent-related intangible asset. We review long-lived assets and intangible assets for potential impairment annually and when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. During the second quarter of 2006, pursuant to the terms of the respective license agreement, management elected to terminate its rights to exclusively license and enforce the patent, resulting in the write-off of the remaining carrying value of the patent-related intangible asset as of June 30, 2006.

As of March 31, 2006, the CombiMatrix group reduced its goodwill and deferred tax liability balances by $1,941,000 which were initially recorded in fiscal 2000, to properly reflect the reduction in its income tax valuation allowance after consideration of the deferred tax liability. As of March 31, 2006, the Acacia Technologies group reduced its patents and deferred tax liability by $691,000, which were initially recorded in fiscal 2002, to properly reflect the reduction in its income tax valuation allowance after consideration of the deferred tax liability.

5. RECENT ACCOUNTING PRONOUNCEMENTS

In February 2006, the Financial Accounting Standards Board (“FASB”) issued FAS No. 155, “Accounting for Certain Hybrid Financial Instruments,” an amendment of FAS No. 133 and FAS No. 140. FAS No. 155 simplifies accounting for certain hybrid instruments under FAS No. 133 by permitting fair value remeasurement for financial instruments that otherwise would require bifurcation and eliminating FAS No. 133 Implementation Issue No. D1, “Application of Statement 133 to Beneficial Interests in Securitized Financial Assets,” which provides that beneficial interests are not subject to the provisions of FAS No. 133. FAS No. 155 also eliminates the previous restriction under FAS No. 140 on passive derivative instruments that a qualifying special-purpose entity may hold. FAS No. 155 is effective for all financial instruments acquired, issued, or subject to a remeasurement event occurring after the beginning of an entity’s fiscal year that begins after September 15, 2006. We do not expect the adoption of this statement to have a material impact on the Acacia Research Corporation, Acacia Technologies group or CombiMatrix group results of operations, financial position or cash flows.

In March 2006, the FASB issued FAS No. 156, “Accounting for Servicing of Financial Assets,” an amendment of FASB Statement No. 140. FAS No. 156 permits entities to choose to either subsequently measure servicing rights at fair value and report changes in fair value in earnings or amortize servicing rights in proportion to and over the estimated net servicing income or loss and assess to rights for impairment or the need for an increased obligation. FAS No. 156 also clarifies when a servicer should separately recognize servicing assets and liabilities, requires all separately recognized assets and liabilities to be initially measured at fair value, if practicable, permits a one-time reclassification of available-for-sales securities to trading securities by an entity with recognized servicing rights and requires additional disclosures for all separately recognized servicing assets and liabilities. FAS No. 156 is effective as of the beginning of an entity’s fiscal year that begins after September 15, 2006. We do not expect the adoption of this statement to have a material impact on the Acacia Research Corporation, Acacia Technologies group or CombiMatrix group results of operations, financial position or cash flows.

In July 2006, the FASB issued Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes,” which clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” FIN 48 provides guidance on the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosures, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. We are currently evaluating the impact of this standard on our consolidated and separate operating group financial statements.

6.  EQUITY FINANCING
 
On June 14, 2006, Acacia Research Corporation entered into a standby equity distribution agreement (the “SEDA”) with Cornell Capital Partners, LP (“Cornell”). Under the terms of the SEDA, Acacia Research Corporation can require Cornell to purchase up to $50.0 million of AR-CombiMatrix common stock, or up to 13,024,924 shares, over a two-year period following the effective date of the SEDA. Such shares will be in the form of registered securities drawn from Acacia Research Corporation’s current shelf registration statement. All proceeds from each advance will be contributed to the CombiMatrix group. Acacia Research Corporation can request advances under the SEDA in up to $5.0 million increments. At the closing of each advance, which will take place six days after the initial notification to Cornell, Acacia Research Corporation will issue to Cornell a number of shares of AR-CombiMatrix common stock equal to the amount of the advance divided by the lowest daily volume weighted average price (“VWAP”) of AR-CombiMatrix common stock during the five trading days following the advance notice to Cornell, which will purchase the shares at 97.5% of the VWAP. Management can also specify a floor price whereby shares that trade below this price during the five-day trading period will be excluded from determining the VWAP. At each closing, Acacia Research Corporation will pay an underwriting fee of 4% of the gross amount of each advance on the first $20.0 million and 5% of the gross proceeds of each advance on the remaining $30.0 million of the SEDA to Cornell. Acacia Research Corporation is not obligated to request any advances under the agreement and will not pay any additional fees to Cornell so long as no advances are requested. The SEDA is also cancelable by Acacia Research Corporation at any time, without penalty. Acacia Research Corporation may not request advances if the shares to be issued in connection with such advances would result in Cornell owning more than 9.9% of the outstanding AR-CombiMatrix common stock. A total of 13,024,924 shares of AR-CombiMatrix common stock are authorized to be issued under the SEDA.

Upon closing of the SEDA, the CombiMatrix group paid Cornell a one-time commitment fee of $550,000 and an additional $20,000 in due diligence and other closing-related costs. The $550,000 fee was recorded as a long-term asset and will be amortized against future advances as costs of equity issuances. On June 23 2006, Cornell purchased 343,750 shares of AR-CombiMatrix common stock at $1.60 per share, based on the fair value of AR-CombiMatrix stock on June 12, 2006. The shares of AR-CombiMatrix stock were offered pursuant to an effective registration statement previously filed with the Securities and Exchange Commission. As of July 26, 2006, Acacia Research Corporation had completed one advance under the SEDA, selling a total of 429,849 shares of AR-CombiMatrix common stock for gross proceeds of approximately $500,000, resulting in net proceeds attributed to the CombiMatrix group of approximately $480,000. As of June 30, 2006, $49,450,000, or up to 12,681,174 shares of AR-CombiMatrix common stock are available under the SEDA.

In February 2005, Acacia Research Corporation raised gross proceeds of $19,600,000 through the sale of 3,500,000 shares of AR-Acacia Technologies stock at a price of $5.60 per share in a registered direct offering. Net proceeds raised of approximately $19,532,000, which are net of related issuance costs, were attributed to the Acacia Technologies group. The shares of AR-Acacia Technologies stock were offered pursuant to an effective registration statement previously filed with the Securities and Exchange Commission.

7. ACQUISITION

On January 28, 2005, Acacia Global Acquisition Corporation, a wholly owned subsidiary of Acacia Research Corporation, acquired substantially all of the assets of Global Patent Holdings, LLC, a privately held patent holding company based in Northbrook, Illinois, which owned 11 patent licensing companies. The acquisition provided the Acacia Technologies group 100% ownership of companies that control 27 patent portfolios, which include 120 U.S. patents and certain foreign counterparts, and cover technologies used in a wide variety of industries. As a result of the acquisition, we have expanded and diversified the Acacia Technologies group’s potential revenue generating activities.

The acquisition was accounted for in accordance with the purchase method of accounting. Under the purchase method of accounting, the purchase consideration is allocated to the assets acquired, including tangible assets, patents and other identifiable intangibles and liabilities assumed, based on their estimated fair values at the date of acquisition. The consolidated statement of operations includes the results of the acquired companies beginning on January 28, 2005, the date of acquisition. The aggregate purchase consideration was approximately $25,105,000, including $5.0 million of cash, the issuance of 3,938,832 shares of AR-Acacia Technologies stock valued at $19,293,000 (net of estimated common stock registration costs of $228,000) and acquisition costs, including registration costs, of $812,000. The value of the common shares issued was determined based on the average market price of AR-Acacia Technologies stock, as reported on NASDAQ, over the 5-day period (December 13 - December 17, 2004) before and after the terms of the acquisition were agreed to and announced.

The following table summarizes the total purchase consideration and the allocation of the consideration paid to the estimated fair value of the assets acquired and liabilities assumed (in thousands):

Management was primarily responsible for determining the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed at the date of acquisition. Management considered a number of factors in estimating the fair value of the intangible assets acquired, including reference to an independent valuation. The patents and patent rights acquired were valued using a discounted cash flow model on a patent portfolio by portfolio basis, which estimated the future net cash flows expected to result from the licensing of each portfolio, taking into account potential infringers of the patents, usage of the underlying technologies, estimated license fee revenues, contingent legal fee arrangements, royalties due to former patent holders, other estimated costs, tax implications and other factors. A discount rate consistent with the risks associated with achieving the estimated net cash flows was used to estimate the present value of future estimated net cash flows. Management’s valuation resulted in an estimated fair value of patent related assets acquired of approximately $27,000,000, resulting in approximately $1,900,000 of excess fair value over the cost of net assets acquired, which has been allocated as a pro rata reduction to the amounts that otherwise would have been assigned to the assets acquired, in accordance with the purchase method of accounting.

Amounts attributable to patents and patent rights acquired are amortized using the straight-line method over the estimated economic useful lives of the underlying patents which range from two to seven years. At the date of acquisition, the estimated weighted average useful life of amortizable patent related intangibles acquired was approximately 6 years.

In connection with the acquisition described above, Acacia Global Acquisition Corporation entered into a consulting agreement with the former CEO of Global Patent Holdings, LLC who, as a result of the acquisition transaction, is also a shareholder of Acacia Research Corporation. The agreement requires the payment of $2,000,000 in consulting fees over a two-year period, and certain reimbursable consulting related expenses, commencing on the date of acquisition. Marketing, general and administrative expenses for the three and six months ended June 30, 2006 include $271,000 and $544,000, respectively, in expenses related to the consulting agreement. Marketing, general and administrative expenses for the three and six months ended June 30, 2005 include $271,000 and $466,000, respectively, in expenses related to the consulting agreement. Consulting services to be performed consist primarily of consultation on intellectual property matters associated with the patents and patent rights acquired in the transaction. The consulting fees are being expensed in the consolidated statement of operations as the consulting services are rendered during the two-year term of the consulting agreement. Acacia Global Acquisition Corporation may terminate the consulting agreement for cause as provided for in the agreement. The consulting agreement also contains certain automatic termination provisions, including; the failure by Acacia Global Acquisition Corporation to make timely consulting payments in accordance with the agreement; a significant decrease in working capital of Acacia Research Corporation, as defined in the agreement; material breach of the agreement by Acacia Global Acquisition Corporation; and the death of the consultant. Any occurrence of these conditions may require the payment of all remaining consulting fees outstanding under the agreement within thirty days of the occurrence of the termination event. Acacia Research Corporation also executed an agreement guaranteeing Acacia Global Acquisition Corporation’s performance of its obligations under the consulting agreement.

The acquisition was treated for tax purposes as a taxable asset acquisition and, as such, Acacia Research Corporation did not record any book/tax basis differences and thus, no deferred income taxes were recorded in connection with the application of the purchase method of accounting. Differences between the book and tax amortization period for amounts allocated to patented related intangibles give rise to deferred tax assets.

8. COMMON STOCK PURCHASE WARRANT LIABILITY
 
Acacia Research Corporation’s classes of common stock are subject to certain redemption provisions in the event that Acacia Research Corporation sells, transfers, assigns or otherwise disposes of, in one transaction or a series of related transactions, all or substantially all of the properties and assets attributed to either group.

Acacia Research Corporation adopted FASB Staff Position No. 150-5 (“FSP No. 150-5”), effective July 1, 2005, which requires that warrants for shares that are redeemable be classified as liabilities, based on the fair values of the warrants, which are required to be marked to market at each balance sheet date. The fair value of contingently redeemable AR-CombiMatrix stock purchase warrants outstanding at June 30, 2006 and December 31, 2005 was $1,631,000 and $1,381,000, respectively. Net warrant gains (charges) for the three and six months ended June 30, 2006, reflected in other income (expense), related to changes in the fair value of the warrant liability totaled $1,490,000 and ($250,000), respectively.

The fair value of AR-CombiMatrix stock purchase warrants was determined using the Black-Scholes option-pricing model, assuming weighted average risk free interest rates over the remaining term of the warrants of approximately 4.35% in December 2005 and 5.16% (two-year) and 5.10% (four year) in June 2006, volatility over the remaining term of the warrants of 84% in December 2005 and 77% and 82% in June 2006, and remaining terms of two to four years.

9. STOCK BASED COMPENSATION PLANS
 
The 2002 Acacia Technologies Stock Incentive Plan (the “AR-Acacia Technologies Group Plan”) and the 2002 CombiMatrix Stock Incentive Plan (the “AR-CombiMatrix Group Plan”) were approved by the stockholders of Acacia Research Corporation in December 2002. The AR-Acacia Technologies Group Plan authorizes grants of stock options, stock awards and performance shares with respect to AR-Acacia Technologies stock. The AR-CombiMatrix Group Plan authorizes grants of stock options, stock awards and performance shares with respect to AR-CombiMatrix stock. Directors and certain officers and key employees with responsibilities involving both the Acacia Technologies group and the CombiMatrix group may be granted awards under both incentive plans in a manner which reflects their responsibilities. The board of directors believes that granting participants awards tied to performance of the group in which the participants work and, in certain cases the other group, is in the best interest of the Acacia Research Corporation and its stockholders. The terms of the AR-Acacia Technologies Group Plan and the AR-CombiMatrix Group Plan are identical except that AR-Acacia Technologies stock may be issued only under the AR-Acacia Technologies Group Plan and AR-CombiMatrix stock may be issued only under the AR-CombiMatrix Group Plan.

Acacia Research Corporation’s compensation committee administers the discretionary option grant and stock issuance programs. This committee determines which eligible individuals are to receive option grants or stock issuances under those programs, the time or times when the grants or issuances are to be made, the number of shares subject to each grant or issuance, the status of any granted option as either an incentive stock option or a non-statutory stock option under the federal tax laws, the vesting schedule to be in effect for the option grant or stock issuance and the maximum term for which any granted option is to remain outstanding. The exercise price of options is generally equal to the fair market value of the AR-CombiMatrix stock or AR-Acacia Technologies stock on the date of grant. Options generally begin to be exercisable six months to one year after grant and generally expire ten years after grant. Stock options generally vest over three to four years and restricted shares generally vest in full after two years (represents the requisite service period under SFAS No. 123R).
 
The authorized number of shares of common stock subject to the AR-Acacia Technologies Group Plan is 7,208,000 shares. The authorized number of shares of common stock subject to the AR-CombiMatrix Group Plan is 10,910,000 shares. The number of shares of common stock available for issuance under the AR-Acacia Technologies Group Plan and the AR-CombiMatrix Group Plan automatically increases on the first trading day of January each calendar year during the term of the Plan by an amount equal to three percent (3%) of the total number of shares of common stock outstanding on the last trading day in December of the immediately preceding calendar year, but in no event shall any such annual increase exceed 500,000 shares for the AR-Acacia Technologies Group Plan and 600,000 shares for the AR-CombiMatrix Group Plan. The aggregate number of shares of common stock available for issuance under either Plan shall not exceed 20,000,000 shares. At June 30, 2006, shares available for grant are 105,510 and 2,734,930 under the AR-Acacia Technologies Group Plan and the AR-CombiMatrix Group Plan, respectively.  The AR-Acacia Technologies Group Plan and the AR-CombiMatrix Group Plan do not segregate the number of securities remaining available for future issuance among stock options and other awards. The shares authorized for future issuance represents the total number of shares available through any combination of stock options or other awards. Upon the exercise of stock options or the granting of restricted stock, it is Acacia Research Corporation’s policy to issue new shares of the respective class of common stock.

There are no restricted share grants outstanding under the AR-CombiMatrix Group Plan.
 
At June 30, 2006, Acacia Research Corporation and its separate operating groups continue to record a full valuation allowance against its deferred tax assets due to management’s determination that the criteria for recognition have not been met. As such, the implementation and subsequent accounting for stock based awards under SFAS No. 123R did not have an impact on Acacia Research Corporation’s or the separate group’s deferred taxes or related tax provisions for the periods presented.

CombiMatrix Molecular Diagnostics 2005 Stock Award Plan

CombiMatrix Corporation’s wholly owned subsidiary, CMDX, executed the CombiMatrix Molecular Diagnostics 2005 Stock Award Plan (the "CMDX Plan") with plan provisions and terms similar to that of the AR-CombiMatrix Group Plan, as described above. The authorized number of shares of common stock subject to the CMDX Plan is 4,000,000 shares. At June 30, 2006, shares available for grant under the CMDX Plan are 2,038,000.

10. COMMITMENTS AND CONTINGENCIES

Collaborative and Research Agreements

On February 8, 2006, the CombiMatrix group executed a one-year, $2.1 million contract with the Department of Defense (“DoD”) to further the development of the CombiMatrix group's array technology for the detection of biological and chemical threat agents. Under the terms of the CombiMatrix group’s one-year contract with the DoD, the CombiMatrix group will perform research and development activities, as described under the contract, and will be reimbursed on a periodic basis for actual costs incurred to perform its obligations, plus a fixed fee, of up to $2.1 million. The CombiMatrix group expects to incur approximately $991,000 in research and development costs for the remainder of 2006 to complete its obligations to the DoD under this contract. As of June 30, 2006, the biological threat detection contract with the DoD was approximately 38% complete. In March 2004, the CombiMatrix group was awarded a two-year, $5.9 million contract with the DoD to further the development of the CombiMatrix group’s array technology for the detection of biological and chemical threat agents. The two-year $5.9 million contract was completed in December 2005.

In October 2004, the CombiMatrix group entered into an agreement to acquire up to a one-third ownership interest in Leuchemix, Inc. (“Leuchemix”), a private drug development firm, which is developing several compounds for the treatment of leukemia and other cancers. In accordance with the terms of the purchase agreement, the CombiMatrix group will purchase 3,137,500 shares of Series A Preferred Stock of Leuchemix for a total purchase price of $4,000,000. The ownership interest will be acquired and paid for quarterly over the two-year period commencing with the fourth quarter of 2004. In accordance with the terms of the purchase agreement, the CombiMatrix group made an additional $750,000 investment in Leuchemix during the three months ended June 30, 2006, resulting in an ownership interest of approximately 29% as of June 30, 2006. The CombiMatrix group will make a final contractual investment in Leuchemix of $750,000 in the third quarter of 2006 in accordance with the terms of the agreement. The CombiMatrix group’s investment is being accounted for under the equity method.

Litigation and Patent Enforcement

Acacia Research Corporation is subject to claims, counterclaims and legal actions that arise in the ordinary course of business. Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on our financial position, results of operations or cash flows. Companies comprising the Acacia Technologies group are often required to engage in litigation to enforce their patents and patent rights.

On September 30, 2002, CombiMatrix Corporation and Dr. Donald Montgomery entered into a settlement agreement with Nanogen, Inc. to settle all pending litigation between the parties. During the six months ended June 30, 2005, the CombiMatrix group recorded a net non-cash credit totaling $195,000 in connection with certain anti-dilution provisions of the settlement agreement. The related liability reflected management’s estimate, as of each balance sheet date, of the fair value of AR-CombiMatrix stock potentially issuable to Nanogen, Inc. as a result of certain options and warrants exercised during the period, if any, and the fair value of AR-CombiMatrix stock potentially issuable to Nanogen, Inc. as of each balance sheet date pursuant to the anti-dilution terms of the agreement. The liability was adjusted at each balance sheet date for changes in the market value of the AR-CombiMatrix stock and was reflected as long-term until settled in equity. The anti-dilution provisions of the settlement agreement expired in September 2005 and thus, there is no liability recorded as of September 30, 2005, or in any future periods, and there were no charges or credits recognized during the three and six months ending June 30, 2006.

In addition to other terms of the settlement agreement, CombiMatrix Corporation is also required to make quarterly payments to Nanogen, Inc. equal to 12.5% of payments to CombiMatrix Corporation from sales of products developed by CombiMatrix Corporation and its affiliates and based on the patents that had been in dispute in the litigation, up to an annual maximum of $1,500,000. The minimum quarterly payments under the settlement agreement are $25,000 per quarter until the patents expire in 2018. Royalties recognized under the agreement during the six months ended June 30, 2006, and 2005, were $161,000 and $53,000, respectively.

Inventor Royalties and Contingent Legal Expenses

In connection with the acquisition of certain patents and patent rights, certain companies included in the Acacia Technologies group executed related agreements which grant to the former owners of the respective patents or patent rights, the right to receive inventor royalties based on future net license fee revenues (as defined in the respective agreements) generated by the Acacia Technologies group as a result of licensing the respective patents or patent portfolios. Inventor royalties paid pursuant to the agreements are expensed in the consolidated statement of operations and comprehensive loss in the period that the related license fee revenues are recognized.

In connection with the Acacia Technologies group’s licensing and enforcement activities, the Acacia Technologies group may retain the services of law firms that specialize in intellectual property licensing and enforcement and patent law. These law firms may be retained on a contingent fee basis in which the law firms are paid on a scaled percentage of any negotiated license fees, settlements or judgments awarded based on how and when the license fees, settlements or judgments are obtained by the Acacia Technologies group. In instances where the Acacia Technologies group does not recover license fees from potential infringers, no contingent legal fees are paid; however, the Acacia Technologies group is generally liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.

Guarantees and Indemnifications

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

11. DISCONTINUED OPERATIONS

Results for the six months ended June 30, 2005, include a $210,000 charge, net of minority interests, related to estimated additional costs to be incurred in connection with the discontinued operations of Soundbreak.com (originally ceased operations in February 2001), related primarily to certain noncancellable lease obligations and a reduction in estimated amounts recoverable from existing sublease arrangements. The related lease obligations, which were guaranteed by Acacia Research Corporation, expired in August 2005. At June 30, 2006, assets consisted of cash and cash equivalents. At December 31, 2005, assets consisted of cash and cash equivalents and lease deposits. At June 30, 2006, liabilities related to miscellaneous accounts payable. At December 31, 2005, liabilities related primarily to miscellaneous payables and accrued lease termination costs. In April 2006, a final distribution to Soundbreak.com’s minority shareholders was paid totaling $353,000. Refer to Note 13 for additional information on assets and liabilities related to discontinued operations for the periods presented.

12. SALE OF INTEREST IN SUBSIDIARY

In January 2006, the CombiMatrix group expanded its relationship with one of its existing distributors, InBio, for the Asia Pacific region. Major components of the expanded relationship included the transfer of day-to-day operational responsibility and majority ownership of CombiMatrix K.K. to InBio, along with an expanded distribution agreement that encompasses Japan. InBio obtained 67% of the voting interests in CombiMatrix K.K. for a nominal amount of consideration. As a result, InBio assumed all operational and financial responsibilities of CombiMatrix K.K. The net loss on the sale of 67% of the voting interest in CombiMatrix K.K. recorded in the statement of operations in the first quarter of 2006 was $84,000. CombiMatrix Corporation continues to own a 33% interest in CombiMatrix K.K. Subsequent to the sale, the CombiMatrix group’s investment in CombiMatrix K.K. was accounted for under the equity method. The deconsolidation of CombiMatrix K.K. did not have a material impact on the consolidated balance sheets as of June 30, 2006.
