		-1	Summary of Significant Accounting Policies
	Organization
	Unwired Planet, Inc. (referred to as “Unwired Planet”, “UPIP”, the “Company”, “our”, “we”, or “us”) is an intellectual property licensing company with approximately 2,450 mobile technology patents and patent applications. Our patents cover technology utilized in telecommunications infrastructure and mobile devices including, among other things, location based services, signal processing, network protocols, radio resource management, voice/text applications, mobility management, mobile payment, software, hardware, and antennas.
	Basis of Presentation
	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 September 30, 2013 and June 30, 2013, and the results of its operations and cash flows for the three months ended September 30, 2013 and 2012. 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, 2013.
	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.
	Contingent Legal Expenses
	The Company retains the services of law firms that specialize in intellectual property licensing, enforcement, and patent law. These law firms are retained on an hourly fee, contingent fee, or blended fee basis. In a contingency fee arrangement, law firms are paid a scaled percentage of any negotiated license fees, settlements or judgments awarded. Contingent legal fees are expensed in the condensed consolidated statements of operations in the period it is probable the fees are due and the fees can be reasonably estimated. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, the Company may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement which are expensed as incurred. Legal fees that are required to be paid regardless of whether license recoveries are obtained are expensed as incurred. Legal fees and related costs are recorded in patent licensing expenses in the accompanying condensed consolidated statements of operations.
	Cash and cash equivalents
	Cash and cash equivalents are comprised of cash and highly liquid investments with remaining maturities of 90 days or less at the date of purchase. Cash equivalents are comprised of short-term investments with an investment rating of any two of the following: Moody’s of A-2 or higher, or Standard & Poor’s of A1 or higher at the time of purchase. The Company is exposed to credit risk in the event of default by the financial institutions or the issuers of these investments to the extent the amounts recorded on the balance sheet are in excess of amounts that are insured by the FDIC.
	During the three months ended September 30, 2013, approximately $17.3 million of restricted cash was related to the lease on the Company’s prior headquarters, which expired in April 2013 and the related restriction was removed in July 2013. The Company considered this change in restricted cash as an operating activity in the accompanying condensed consolidated statements of cash flows due to the nature of the restricted cash. As of September 30, 2013, the Company had restricted cash deposits of $0.5 million included in deposits and other assets on the condensed consolidated balance sheets.
	Recently Adopted Accounting Pronouncements
	Accounting Standards Update (“ASU”) No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income: This ASU was issued to address concerns raised in the initial issuance of ASU 2011-05, Presentation of Comprehensive Income, for which the Board deferred the effective date of certain provisions relating to the presentation of reclassification adjustments in the income statement. With the issuance of ASU 2013-02, entities are now required to disclose:
	For items reclassified out of accumulated other comprehensive income (“AOCI”) and into net income in their entirety, the effect of the reclassification on each affected net income line item; and
	For AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures. This information may be provided either in the notes or parenthetically on the face of the statement that reports net income as long as all the information is disclosed in a single location. However, an entity is prohibited from providing this information parenthetically on the face of the statement that reports net income if it has items that are not reclassified in their entirety into net income. The Company adopted the new guidance on July 1, 2013. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.
	Accounting Standards Update No. 2013-05, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity: This ASU addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The Company adopted the new guidance on July 1, 2013. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.
	There were no other recently issued accounting pronouncements expected to have a material impact on the Company’s financial position, results of operations, or cash flows.

	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 tables show the Company’s available-for-sale investments at September 30, 2013 (in thousands):
			Expected maturity for the				Amortized Cost		Fair Value

	At September 30, 2013, the Company recognized unrealized losses on its available for sale securities of $8,000. During the quarter ended September 30, 2013, the Company realized a loss of $0.1 million on the sale and maturity of its investments.

		(b)	Fair Value Measurement
	The FASB has established a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs used in valuation techniques are assigned a hierarchical level. 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 carrying value of the Company’s cash and cash equivalents and investments approximates their fair value and is based on Level 1 inputs. The carrying value of the Company’s accounts payable, accrued liabilities and restructuring liabilities approximates their fair value due to the short-term nature of these instruments and is based on Level 2 inputs. 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 three months ended September 30, 2013.
	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):

	Litigation
		(a)	Openwave Systems Inc.(Unwired Planet) v. Apple Inc. (“Apple”), Research in Motion Ltd, and Research in Motion Corp. (“RIM”) (now known as Blackberry)
	On August 31, 2011, the Company filed a complaint in the Federal District Court for the District of Delaware against Apple and RIM, alleging that Apple and RIM products infringe certain of the Company’s patents, seeking among other things a declaration that the Company’s patents cited in the complaint have been infringed by Apple and RIM and that these patents are valid and enforceable, damages as a result of the infringement, and an injunction against further infringement. This matter had been stayed pending a parallel case filed with the International Trade Commission (“ITC”). The Company withdrew the ITC investigation in October 2012. The Federal District Court in Delaware lifted the stay in January 2013 and the matter is now proceeding.
		(b)	Unwired Planet LLC v. Apple Inc. (“Apple”) & Unwired Planet LLC v. Google, Inc. (“Google”)
	On September 20, 2012, the Company filed a complaint in the U.S. District Court for the District of Nevada, charging Apple with infringing 10 of its patents. The case charges infringement of 10 patents related to smart mobile devices, cloud computing, digital content stores, push notification technologies, and location-based services such as mapping and advertising. On August 30, 2013, the U.S. District Court for the District of Nevada granted Apple’s motion to transfer venue from the District of Nevada to the Northern District of California.
		(c)	Unwired Planet LLC v. Google, Inc. (“Google”)
	On September 20, 2012, the Company filed a complaint in the U.S. District Court for the District of Nevada, charging Google with infringing 10 patents. The case charges infringement of 10 patents related to cloud computing, digital content stores, push notification technologies, and location-based services such as mapping and advertising.
	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.
	Ericsson Master Sales Agreement
	On February 13, 2013, the Company, through a wholly-owned subsidiary, acquired a patent portfolio from a wholly owned subsidiary of Telefonaktiebolaget L M Ericsson (“Ericsson”) that consists 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 purchased 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 an amount equal to a percentage of future gross revenues generated by a combined patent portfolio that includes both the Ericsson Patents plus the Company’s legacy 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 gross revenue, 50% of the next $400 million and 70% of any amounts above $500 million. The fee share has no termination date.
	The Company has recognized cumulative revenues of $106,000 and incurred a cumulative fee share of $21,000 from inception of the Master Sales Agreement through September 30, 2013. The Company did not recognize any revenues nor incur any fee share for the three months ended September 30, 2013.
	Contingent Legal Expenses
	In September 2013, the Company entered into blended fee arrangement with its lead patent infringement counsel for a period of five years. The agreement calls for monthly cash payments of $0.5 million for a period of twenty-four (24) months retroactively commencing on July 1, 2013 and a sliding scale percentage of any negotiated license fees, settlements or judgments awarded, if any, from the three defendants covered up to a maximum of $70 million. During the three months ended September 30, 2013, the Company recognized $1.3 million in legal expenses related to this agreement included in patent licensing expenses in the accompanying condensed consolidated statements of operations.
	Indemnification claims
	Prior to the sale of the Company’s product businesses, the Company’s software license and services agreements generally included a limited indemnification provision for claims from third parties relating to its intellectual property. In connection with the sale of the Company’s product businesses, the Company retains certain ongoing liabilities with respect to indemnification claims related to its former customers that were initiated prior to the sale of the Location business line and the Messaging and Mediation product businesses.
	Originally, three licensees of the Company sought indemnification from the Company under their respective license agreements in connection with being named as defendants in two matters pending in the United States District Court for the Eastern District of Texas captioned Unified Messaging Solutions, Inc. v. Google, et al. (Civil Action No. 6:11cv00464) and Unified Messaging Solutions, Inc. v. Facebook, et al. (Civil Action No. 6:11cv00120) (the “Actions”). Plaintiffs in the Actions allege that the licensees’ web-based communication services infringe patents allegedly owned by the plaintiff and the licensees claim that their web-based services are comprised of products licensed from the Company. The Company has assumed the defense on behalf of two of the licensees. With respect to the third, the licensee conducted its own defense and has resolved this issue.
	As of September 30, 2013, nothing has been accrued for indemnifications.

Basis of Presentation	'
	Basis of Presentation
	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 September 30, 2013 and June 30, 2013, and the results of its operations and cash flows for the three months ended September 30, 2013 and 2012. 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, 2013.
Use of Estimates	'
	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.
Contingent Legal Expenses	'
	Contingent Legal Expenses
	The Company retains the services of law firms that specialize in intellectual property licensing, enforcement, and patent law. These law firms are retained on an hourly fee, contingent fee, or blended fee basis. In a contingency fee arrangement, law firms are paid a scaled percentage of any negotiated license fees, settlements or judgments awarded. Contingent legal fees are expensed in the condensed consolidated statements of operations in the period it is probable the fees are due and the fees can be reasonably estimated. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, the Company may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement which are expensed as incurred. Legal fees that are required to be paid regardless of whether license recoveries are obtained are expensed as incurred. Legal fees and related costs are recorded in patent licensing expenses in the accompanying condensed consolidated statements of operations.
Cash and cash equivalents	'
	Cash and cash equivalents
	Cash and cash equivalents are comprised of cash and highly liquid investments with remaining maturities of 90 days or less at the date of purchase. Cash equivalents are comprised of short-term investments with an investment rating of any two of the following: Moody’s of A-2 or higher, or Standard & Poor’s of A1 or higher at the time of purchase. The Company is exposed to credit risk in the event of default by the financial institutions or the issuers of these investments to the extent the amounts recorded on the balance sheet are in excess of amounts that are insured by the FDIC.
	During the three months ended September 30, 2013, approximately $17.3 million of restricted cash was related to the lease on the Company’s prior headquarters, which expired in April 2013 and the related restriction was removed in July 2013. The Company considered this change in restricted cash as an operating activity in the accompanying condensed consolidated statements of cash flows due to the nature of the restricted cash. As of September 30, 2013, the Company had restricted cash deposits of $0.5 million included in deposits and other assets on the condensed consolidated balance sheets.
Recently Adopted Accounting Pronouncements	'
	Recently Adopted Accounting Pronouncements
	Accounting Standards Update (“ASU”) No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income: This ASU was issued to address concerns raised in the initial issuance of ASU 2011-05, Presentation of Comprehensive Income, for which the Board deferred the effective date of certain provisions relating to the presentation of reclassification adjustments in the income statement. With the issuance of ASU 2013-02, entities are now required to disclose:
	For items reclassified out of accumulated other comprehensive income (“AOCI”) and into net income in their entirety, the effect of the reclassification on each affected net income line item; and
	For AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures. This information may be provided either in the notes or parenthetically on the face of the statement that reports net income as long as all the information is disclosed in a single location. However, an entity is prohibited from providing this information parenthetically on the face of the statement that reports net income if it has items that are not reclassified in their entirety into net income. The Company adopted the new guidance on July 1, 2013. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.
	Accounting Standards Update No. 2013-05, Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity: This ASU addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The Company adopted the new guidance on July 1, 2013. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements.
	There were no other recently issued accounting pronouncements expected to have a material impact on the Company’s financial position, results of operations, or cash flows.
