	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not contain all of the information and notes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2015 and June 30, 2014, and the results of its operations for the three months and nine months ended March 31, 2015 and 2014, and cash flows for the nine months ended March 31, 2015 and 2014. The following information should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2014.
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with the accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

	Recently Issued
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers. This guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for the Company on July 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is currently evaluating the impact that this guidance will have on our consolidated financial statements and disclosures. Additionally, the Company has not selected a transition method.
	Recently Adopted
	In August 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This pronouncement requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures, if applicable. ASU 2014-15 is effective for the Company beginning June 30, 2017, however, early application is permitted. The Company adopted ASU 2014-15 as of the second quarter of fiscal 2015. The adoption of ASU No. 2014-15 did not have a material impact on the Company’s condensed consolidated financial statements or its disclosures.

See Note 9 of the Notes to the Condensed Consolidated Financial Statements for more details. The terms of the contract included provisions for issuance of 1.2 million shares of the Company’s stock in two tranches if specified share price conditions were met (hereinafter referred to as the “Incentive Fee(s)”) by certain dates. In August 2014, the Incentive Fee on the first tranche of 500,000 shares expired as the volume weighted average trading price of the Company’s common stock over 20 days did not equal or exceed $3.00 per share.

	Adoption of replacement shareholder rights plan
	On January 20, 2015, the Board of Directors of the Company adopted a Tax Benefits Preservation Agreement, dated January 20, 2015, between the Company and Computershare Trust Company, N.A., as Rights Agent (the “Agreement”) to replace the Company’s existing Tax Benefits Preservation Agreement, which expired on January 29, 2015, (the “Expiring Agreement”). The Agreement is substantially the same as the Expiring Agreement.
	The Agreement is designed to preserve the Company’s substantial tax assets associated with net operating loss carry forwards (“NOLs”) and built in losses under Section 382 of the Internal Revenue Code. The Company’s ability to use its NOLs and built in losses would be limited if there was an “ownership change” under Section 382. This would occur if shareholders owning (or deemed under Section 382 of the Internal Revenue Code to own) 5% or more of the Company’s stock increase their collective ownership of the aggregate amount of outstanding shares of the Company by more than 50 percentage points over a rolling three-year period.
	Pursuant to the terms of the Agreement, the Board of Directors declared a dividend distribution of one Preferred Stock Purchase Right (a “Right”) for each outstanding share of common stock, par value $0.001 per share of the Company (the “Common Stock”) to stockholders of record as of the close of business on January 29, 2015 (the “Record Date”). In addition, one Right will automatically attach to each share of Common Stock issued between the Record Date and the Distribution Date (as defined in the Agreement). Each Right entitles the registered holder thereof to purchase from the Company a unit consisting of one ten-thousandth of a share (a “Unit”) of Series A Junior Participating Cumulative Preferred Stock, par value $0.001 per share, of the Company (the “Preferred Stock”) at a cash exercise price of $15.00 per Unit (the “Exercise Price”), subject to adjustment, under certain conditions specified in the Agreement. For additional information, please refer to the Company’s Registration Statement on Form 8-A and the Company’s Current Report on Form 8-K, both filed with the Securities and Exchange Commission on January 21, 2015.
	The Rights are not exercisable until the Distribution Date (as defined in the Agreement) and will expire at the earlier of (i) January 29, 2018, (ii) the time when the Rights are redeemed as provided therein; (iii) the time when the Rights are exchanged as provided therein; (iv) the repeal of Section 382 of the Internal Revenue Code if the Independent Directors determine that this Agreement is no longer necessary for the preservation of Tax Benefits (as defined in the Agreement), (v) the beginning of the taxable year of the Company to which the Board determines that no Tax Benefits may be carried forward, or (vi) the close of business on January 29, 2016, if stockholder approval of the Agreement has not been obtained prior to that time, unless previously redeemed or exchanged by the Company.

	(a) Investments
	The Company’s investment policy is consistent with the definition of available-for-sale securities. From time to time, the Company may sell certain securities but the objectives are generally not to generate profits on short-term differences in price. The following table shows the Company’s available-for-sale investments which are included in investments in the Condensed Consolidated Balance Sheets (in thousands):
			March 31, 2015
			Fair Value		Amortized Cost

	Total		$	21,725	$	21,719
	All of our investments will mature by December 31, 2015.
	(b) Fair Value Measurement
	Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based upon the Company’s principal or, in the absence of a principal, most advantageous market for the specific asset or liability.
	The following are the hierarchical levels of inputs to measure fair value:
		•		Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
		•		Level 2: Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
		•		Level 3: Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.
	The Company recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the nine months ended March 31, 2015.
	The following tables summarize the Company’s financial assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy (in thousands):

	Contingent Legal Expenses
	We have entered into several agreements for legal services on a blended fee basis for our patent enforcement matters and are responsible for the current payment of out-of-pocket expenses incurred in connection with the patent enforcement matters. These agreements typically require payment of a fixed fee for a period of time or fixed fees on occurrence of milestones and payment of a contingency fee upon a settlement or collection of a judgment. For the nine months ended March 31, 2015 and 2014, we recognized $6.2 million and $5.3 million, respectively, in legal fees and $5.4 million and $2.6 million respectively, in out-of-pocket costs in the above agreements. Contingency fees in our agreements are usually based upon a percentage of the amount of a settlement or a judgment and are expensed when they are contractually due and payable. Contingency fees we have negotiated are based on successful outcomes in litigation, measured in various ways, such as, for example, a percentage of proceeds net of Ericsson’s fee share. All of the agreements contain dollar limits on the total contingency fee that may be earned.
	Other Legal Matters
	From time to time, the Company may be involved in litigation or other legal proceedings, including those noted above, relating to or arising out of its day-to-day operations or otherwise. Litigation is inherently uncertain and the Company could experience unfavorable rulings. Should the Company experience an unfavorable ruling, there exists the possibility of a material adverse impact on its financial condition, results of operations, cash flows, or on its business for the period in which the ruling occurs and/or in future periods.

	Bonus Arrangement
	In April 2014, the Board entered into a one time, discretionary bonus agreement with the Chairman of the Company’s Board. The agreement provided for a discretionary, one-time, cash bonus opportunity in the event that, on or prior to September 30, 2014, the Company and its subsidiaries entered into an amendment to the Ericsson MSA that would be expected to (A) materially improve the economic terms of the MSA, (B) materially improve the operating flexibility of the Company and its subsidiaries under the MSA, or (C) some combination of the foregoing that, in the aggregate, would be expected to result in a material improvement in the Company’s financial and operating position. If the Board determined that such an agreement occurred on or prior to September 30, 2014, the Chairman was eligible for a cash bonus in an amount not to exceed $2.0 million. In September 2014, the Company entered into a Second Amendment to the MSA which modified its terms in respect to the above points. See Note 9 of the Notes to the Condensed Consolidated Financial Statements for more details. In November 2014, the Company paid a $1.0 million bonus to the Chairman pursuant to the above bonus agreement.
	Separation of the President and Chief Financial & Administrative Officer
	In September 2014, the Company announced that Eric Vetter intended to resign as the Company’s President and Chief Financial & Administrative Officer in November 2014 pursuant to a separation agreement entered into between the Company and Mr. Vetter (the “Separation Agreement”). The Separation Agreement provided that upon Mr. Vetter’s separation from the Company, all of his unvested restricted stock unit awards covering shares of the Company’s common stock would automatically be accelerated and become immediately vested, all unvested options would be forfeited, and the exercise period for all of his vested stock options would be extended for an additional fifteen months. The Separation Agreement provided Mr. Vetter would be entitled to salary continuation for nine months commencing upon separation and a bonus of $0.2 million. Additionally, under the Separation Agreement, Mr. Vetter is entitled to certain benefits continuation and outplacement assistance. For the nine months ended March 31, 2015, the Company incurred $0.3 million in expense and $0.1 million in stock-based compensation for the separation of Mr. Vetter.
Ericsson
Related Party Transactions	-9	Ericsson Master Sales Agreement
	As previously disclosed, the Company and Ericsson are parties to a Master Sale Agreement, dated as of January 10, 2013, as amended by a first amendment dated as of February 27, 2014 and a second amendment dated as of September 16, 2014 (as amended, the “MSA”). Pursuant to the MSA, the Company, through a wholly-owned subsidiary, acquired a patent portfolio from Ericsson that consisted of approximately 2,150 patents and patent applications and the right to receive 100 additional patents per year for five years beginning in 2014. The acquired patents cover technology utilized in telecommunications infrastructure and mobile devices including, among other things, signal processing, network protocols, radio resource management, voice/text applications, mobility management, software, hardware, and antennas and were acquired subject to existing encumbrances.
	The Company is not entitled to royalty payments that are currently being received by Ericsson under third party license agreements on any patents included in the portfolio. Consideration to be paid to Ericsson consists of a nontransferable, limited license to the Company’s patents and a right to receive an amount equal to a percentage of future gross revenues generated by a combined patent portfolio including both the Ericsson Patents plus the Company’s mobility patents (“fee share”). The payments Ericsson will receive from the derived value of the patent portfolio are computed on a tiered basis. Specifically, Ericsson will receive an amount equal to 20% of the first $100 million of cumulative gross revenue, 50% of the next $400 million and 70% of any amounts above $500 million. The fee share has no termination date.
	Until September 2017, the Company may elect to reduce Ericsson’s fee share percentage in the third tier for a price of $5 million per percentage point reduction. The maximum fee share reduction the Company may elect is limited to twenty percentage points, which would require payment to Ericsson of $100 million.
	The MSA contains a number of restrictions on the Company’s future activities. The Company and its affiliates may engage in certain licensing and other patent activities related to non-wireless patents (as defined in the MSA) subject to certain conditions, including not diverting resources otherwise dedicated to Unwired Planet, LLC (“UP LLC”) and its activities and not bundling any such acquired non-wireless patents in licensing activities, provided the Company has made an additional $50 million equity contribution to UP LLC. Such contribution was completed in September 2014.
	In addition, the Company is required to provide advance notice to Ericsson of potential future acquisitions that do not involve wireless patents, and Ericsson has the option to participate in such acquisitions upon mutually agreeable terms and conditions.
	Under the MSA, any amounts withheld by governments on account of taxes on license arrangements would not be included in the calculation of “Gross Revenue”. The MSA requires the Company to use reasonable efforts to reclaim such withholdings. Additionally, Gross Revenues may only be recognized in the period the fees and revenues are due from UP LLC’s and/or its subsidiaries customers.
	The Company has recognized cumulative revenues of $62.8 million and incurred a cumulative fee share of $12.6 million from inception of the MSA through March 31, 2015, including $4.7 million in gross revenues and $0.9 million in fee share for the nine months ended March 31, 2015.
	Pursuant to the MSA, the Company paid $8.4 million to Ericsson in September 2014 with respect to the previously disclosed Lenovo transaction, which amount was accrued for by the Company on June 30, 2014.
	See Notes 3 and 4 of the Notes to the Consolidated Financial Statements in the Company’s Form 10-K for the fiscal year ended June 30, 2014 for additional information.
