CombiMatrix Group

Our life sciences business, referred to as the “CombiMatrix group,” a division of Acacia Research Corporation, is comprised of our wholly owned subsidiary, CombiMatrix Corporation and CombiMatrix Corporation’s wholly owned subsidiary, CombiMatrix Molecular Diagnostics, and includes all corporate assets, liabilities and transactions related to Acacia Research Corporation’s life sciences business.

The CombiMatrix group is seeking to become a diversified biotechnology business, through the development of proprietary technologies, products and services in the areas of drug development, genetic analysis, molecular diagnostics, nanotechnology research, defense and homeland security markets, as well as other potential markets where its products and services could be utilized. The technologies developed include a platform technology to rapidly produce customizable, in-situ synthesized, oligonucleotide arrays for use in identifying and determining the roles of genes, gene mutations and proteins. This technology has a wide range of potential applications in the areas of genomics, proteomics, biosensors, drug discovery, drug development, diagnostics, combinatorial chemistry, material sciences and nanotechnology. Other technologies include proprietary molecular synthesis and screening methods for the discovery of potential new drugs. CombiMatrix Molecular Diagnostics, Inc. (“CMDX”), a wholly owned subsidiary of CombiMatrix Corporation located in Irvine California, has developed capabilities of producing arrays that utilize bacterial artificial chromosomes, which also enable genetic analysis.

CombiMatrix Group Split-off Transaction and Related Discontinued Operations.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. CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the Securities and Exchange Commission on June 8, 2007.  Following the redemption period required by Acacia Research Corporation’s Restated Certificate of Incorporation, on August 15, 2007 (the “Redemption Date”), CombiMatrix Corporation will split-off from Acacia Research Corporation through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock (the “Split-off Transaction”). On the Redemption Date, every ten (10) shares of Acacia Research-CombiMatrix stock outstanding on August 15, 2007, will be redeemed for one (1) share of common stock of CombiMatrix Corporation. As of June 30, 2007, CombiMatrix Corporation continues to be wholly owned by Acacia Research Corporation, and will continue to be wholly owned by Acacia Research Corporation until the August 15, 2007 Redemption Date. Subsequent to the Redemption Date, Acacia Research Corporation will no longer own any equity interests in CombiMatrix Corporation and the two companies will operate independently of each other.

Refer to Note 7 for information regarding presentation of the assets, liabilities, results of operations and cash flows for the CombiMatrix group as Discontinued Operations in the accompanying consolidated financial statements for all periods presented, in accordance with guidance set forth in SFAS No. 144.

Capital Structure. Acacia Research Corporation has two classes of common stock called Acacia Research-Acacia Technologies common stock (“AR-Acacia Technologies stock”) and Acacia Research-CombiMatrix common stock (“AR-CombiMatrix stock”). AR-Acacia Technologies stock is intended to reflect separately the performance of Acacia Research Corporation’s Acacia Technologies group. AR-CombiMatrix stock is intended to reflect separately the performance of Acacia Research Corporation’s CombiMatrix group. Although the AR-Acacia Technologies stock and the AR-CombiMatrix 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.

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 Securities and Exchange Commission (“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, 2006, 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, 2007, 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, 2007 are not necessarily indicative of the results to be expected for the entire year.

Separate Group Presentation. AR-Acacia Technologies stock and AR-CombiMatrix stock are intended to reflect the separate performance of the respective division of Acacia Research Corporation. The Acacia Technologies group and the CombiMatrix group are not separate legal entities. Holders of AR-Acacia Technologies stock and AR-CombiMatrix stock are stockholders of Acacia Research Corporation. As a result, holders of AR-Acacia Technologies stock and AR-CombiMatrix 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 information has 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 information of the groups reflects the financial condition, results of operations, and cash flows of the businesses included therein. The financial information of the groups includes 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. Refer to Note 9 for separate group financial information.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted 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.

Concentrations. Threelicensees individually accounted for 21%, 14% and 14% of the Acacia Technologies group’s license fee revenues recognized during the three months ended June 30, 2007, and twolicensees individually accounted for 31% and 20% of the Acacia Technologies group’s license fee revenues recognized during the six months ended June 30, 2007. Four licensees individually accounted for 23%, 21%, 10% and 10% of the Acacia Technologies group’s license fee revenues recognized during the three months ended June 30, 2006, and two licensees individually accounted for 17% and 16% of the Acacia Technologies group’s license fee revenues recognized during the six months ended June 30, 2006. Two licensees individually represented approximately 39% and 21% of the Acacia Technologies group’s accounts receivable at June 30, 2007. Three licensees individually represented approximately 37%, 24% and 13% of the Acacia Technologies group’s accounts receivable at December 31, 2006.

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. The compensation cost for all stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (generally the vesting period of the equity award) which is generally two to four years.

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

SFAS No. 123R requires stock-based compensation expense to be recorded only for those awards expected to vest using an estimated forfeiture rate. Acacia Research Corporation estimates pre-vesting option forfeitures at the time of grant and reflects the impact of estimated pre-vesting option forfeitures on compensation expense recognized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Income Taxes. Effective January 1, 2007, Acacia Research Corporation adopted FASB 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. In accordance with FIN 48, a tax position is a position in a previously filed tax return or a position expected to be taken in a future tax filing that is reflected in measuring current or deferred income tax assets and liabilities. Tax positions shall be recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position will be sustained upon examination. Tax positions that meet the more likely than not threshold should be measured using a probability weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement. The adoption of FIN 48 did not have a material impact on our consolidated or separate group financial position, results of operations or cash flows.

The total amount of unrecognized tax benefits as of January 1, 2007 and June 30, 2007 was $56,000, all of which, if recognized, would affect the effective tax rate. 

Acacia Research Corporation recognizes interest and penalties with respect to unrecognized tax benefits in income tax expense.  We have identified no uncertain tax position for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within 12 months.

Acacia Research Corporation is subject to taxation in the U.S. and various state jurisdictions. With no material exceptions, Acacia Research Corporation is no longer subject to U.S. federal or state examinations by tax authorities for years before 2001.

At December 31, 2006, the Acacia Technologies group’s U.S. federal and state income tax net operating loss carryforwards were approximately $53,727,000 (excluding NOLs related to subsidiaries for which Acacia Research Corporation does not file a consolidated return) and $54,700,000, expiring between 2007 and 2026. At December 31, 2006, the CombiMatrix group had federal net operating loss carryforwards of approximately $117,056,000, which will begin to expire in 2010 through 2026. At December 31, 2006, consolidated federal research and development (“R&D”) credit carryforwards were approximately $4,014,000, which begin to expire in 2017. Due to uncertainties surrounding our ability to generate future taxable income to realize these assets, a full valuation allowance has been established to offset our net deferred tax assets. All NOLs and tax credits attributed to the Acacia Technologies group will be retained by the Acacia Research Corporation, subsequent to the Split-off Transaction. All NOLs and tax credits attributed to the CombiMatrix group will be retained by the CombiMatrix group and will not be available to Acacia Research Corporation, subsequent to the Split-off Transaction.

Utilization of the NOL and R&D credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change” as defined by Section 382 of the Code results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. Since Acacia Research Corporation’s formation, we have raised capital through the issuance of capital stock on several occasions (both before and after its public offering) which, combined with the purchasing stockholders’ subsequent disposition of those shares, may have resulted in such an ownership change, or could result in an ownership change in the future upon subsequent disposition.

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

3.  EARNINGS PER SHARE

Earnings (Loss) 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 or loss 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 common stock equivalents. Potentially dilutive common stock equivalents primarily consist of employee stock options, unvested restricted stock grants and common stock purchase warrants.

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, consistently applied. 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 following table presents a reconciliation of basic and diluted income (loss) per share:

	For the Three Months Ended				For the Six Months Ended

4.  INTANGIBLE ASSETS

Acacia Research Corporation’s only identifiable intangible assets at June 30, 2007 and December 31, 2006, are patents. Patent related accumulated amortization totaled $14,433,000 and $11,802,000 as of June 30, 2007 and December 31, 2006, respectively.

The Acacia Technologies group’s patents have remaining estimated economic useful lives ranging from one to seven years. The weighted average remaining estimated economic useful life of the Acacia Technologies group’s patents is four years. Annual aggregate amortization expense is estimated to be $2,719,000 for the remainder of 2007, $4,119,000 in 2008, $3,668,000 in 2009, $3,477,000 in 2010 and $2,523,000 in 2011. At June 30, 2007 and December 31, 2006, all of our acquired intangible assets other than goodwill were subject to amortization.

For the six months ended June 30, 2007 and 2006, the Acacia Technologies group paid patent acquisition costs totaling $1,395,000 and $1,020,000 in connection with the acquisition of the rights to additional patent portfolios. The patents acquired have estimated economic useful lives ranging from five to seven years.

5.  RECENT ACCOUNTING PRONOUNCEMENTS

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities Including an Amendment of FASB Statement No. 115” (“SFAS No. 159”).  SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value, with unrealized gains and losses related to these financial instruments reported in earnings at each subsequent reporting date.  We are currently assessing the impact, if any, of adopting SFAS No. 159 on our consolidated and separate group financial position, results of operations and cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 establishes a common definition for fair value to be applied to US GAAP guidance requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. We are currently assessing the impact, if any, of adopting SFAS No. 157 on our consolidated and separate group financial position, results of operations and cash flows.

6.  COMMITMENTS AND CONTINGENCIES

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.

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 income (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 may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement. Legal fees advanced by contingent law firms that are required to be paid in the event that no license recoveries are obtained by the Acacia Technologies group are expensed as incurred and included in liabilities in the statement of financial position.

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.

7.  DISCONTINUED OPERATIONS

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. CombiMatrix Corporation’s registration statement on Form S-1 was declared effective by the SEC on June 8, 2007. Following the redemption period required by Acacia Research Corporation’s Restated Certificate of Incorporation, on August 15, 2007 (the “Redemption Date”), CombiMatrix Corporation will split-off from Acacia Research Corporation through the redemption of all outstanding shares of Acacia Research-CombiMatrix common stock (“AR-CombiMatrix stock”). On the Redemption Date, every ten (10) shares of AR-CombiMatrix stock outstanding on August 15, 2007, will be redeemed for one (1) share of common stock of CombiMatrix Corporation. As of June 30, 2007 CombiMatrix Corporation continues to be wholly owned by Acacia Research Corporation, and will continue to be wholly owned by Acacia Research Corporation until the August 15, 2007 Redemption Date. Subsequent to the Redemption Date, Acacia Research Corporation will no longer own any equity interests in CombiMatrix Corporation and the two companies will operate independently of each other.

In accordance with guidance set forth in SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” since the assets, liabilities, results of operations and cash flows of the CombiMatrix group will be eliminated from the ongoing operations of Acacia Research Corporation as a result of the eventual consummation of the Split-off Transaction (on the Redemption Date) and Acacia Research Corporation will not have any continuing involvement in the operations of the CombiMatrix group subsequent to the consummation of the Split-off Transaction, Acacia Research Corporation’s accompanying consolidated balance sheet, statements of operations and statement of cash flows for the current periods presented reflect the assets, liabilities, results of operations and cash flows for the CombiMatrix group as Discontinued Operations. Financial statements presented for comparable prior year periods have also been restated to reflect the assets, liabilities, results of operations and cash flows for the CombiMatrix group as Discontinued Operations. The CombiMatrix group was previously presented as a separate operating segment of Acacia Research Corporation under SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.”

Refer to Note 9 for detailed information regarding the assets and liabilities of the CombiMatrix group that have been segregated from continuing operations and presented as discontinued operations in the accompanying consolidated balance sheets. Refer to Note 9 for detailed information regarding the revenues and expenses of the CombiMatrix group that have been segregated from continuing operations and reported as Discontinued Operations in the accompanying consolidated statements of operations. Refer to Note 9 for detailed information regarding cash flows from operating, investing and financing activities of the CombiMatrix group that have been segregated from continuing operations and reported as Discontinued Operations in the accompanying consolidated statements of cash flows. Upon consummation of the Split-off Transaction on the Redemption Date, the Split-off Transaction will be accounted for by Acacia Research Corporation at historical cost. Accordingly, no gain or loss on disposal will be recognized in the statement of operations by Acacia Research Corporation.

Net loss from Discontinued operations related to the CombiMatrix group includes direct costs incurred in connection with the Split-off Transaction, originally included in Acacia Research Corporation corporate accounts, totaling $100,000 and $136,000 for the three and six months ended June 30, 2007 and $58,000 and $89,000 for the three and six months ended June 30, 2006.

8. EQUITY FINANCING

On May 4, 2007, Acacia Research Corporation executed a registered direct offering with certain directors of CombiMatrix Corporation and other unaffiliated investors raising gross proceeds of $5,000,000 through the issuance of 6,780,931 units. Each unit consists of one share of AR-CombiMatrix common stock and 1.5 ten-year common stock warrants, for a total of 6,780,931 shares and warrants to purchase 10,171,397 shares of AR-CombiMatrix common stock, respectively, issued to investors. Each warrant entitles the holder to purchase a share of AR-CombiMatrix stock at a price of $0.55 per share. The proceeds from this financing were attributed to the CombiMatrix group, and are reflected in net cash provided by financing activities from discontinued operations in the accompanying Acacia Research Corporation consolidated statement of cash flows.

9.  CONSOLIDATING SEGMENT INFORMATION

Acacia Research Corporation has adopted the provisions of SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” Our chief operating decision maker is considered to be Acacia Research Corporation’s Chief Executive Officer (“CEO”).
