	1.  Description of Business
	ParkerVision, Inc. (“we”, the “Company”, or “ParkerVision”) is in the business of innovating fundamental wireless technologies.   We design, develop and market our proprietary radio frequency (“RF”) technologies and products for use in semiconductor circuits for wireless communication products.   Our business is expected to include licensing of our intellectual property and/or the sale of integrated circuits based on our technology for incorporation into wireless devices designed by our customers.   In addition, from time to time, we offer engineering consulting and design services to our customers, for a negotiated fee, to assist them in developing prototypes and/or products incorporating our technologies.

	On October 24, 2013, a jury in the United States District Court in the Middle District of Florida awarded us $172.7 million in damages for infringement of four of our patents by Qualcomm Incorporated (“Qualcomm”).  The parties have a number of post-trial motions and briefs to be filed, including our request for an injunction against Qualcomm, or alternatively, ongoing royalties for future infringing sales by Qualcomm.  We do not know at this time when the court will ultimately rule on these outstanding motions.   Refer to Legal Proceedings in note 11 for further discussion of our litigation against Qualcomm.

	3.  Liquidity and Capital Resources
	Our future business plans call for continued investment in sales, marketing, customer support and product development for our technologies and products, as well as investment in continued protection of our intellectual property including prosecution of new patents and defense of existing patents.  Our ability to generate revenues sufficient to offset costs is subject to our ability to successfully support our customers in completing their initial product designs incorporating our technologies, our ability to secure a reasonable share of the market through additional product offerings with our current customers and/or the addition of new customers, and our ability to defend our intellectual property.
	Revenue generated from the sale of our RF chipsets in 2013, if any, will not be sufficient to cover our operational expenses.  In addition, the amount and timing of the collection of damages from our jury verdict against Qualcomm is dependent upon final disposition of the litigation which may include settlement discussions and/or appeals.  Our capital resources include $23.1 million in cash and available for sale securities at September 30, 2013.  We believe these resources are sufficient to support our currently projected liquidity requirements for at least the next twelve months.
	We operate in a highly competitive industry with rapidly changing and evolving technologies.  Many of our potential competitors have substantially greater financial, technical and other resources.  We have made significant investments in developing our technologies and products, the returns on which are dependent upon the generation of future revenues for realization.  The long-term continuation of our business plan is dependent upon the generation of sufficient revenues from our technologies and products to offset expenses.  In the event that we do not generate sufficient revenues, we will be required to obtain additional funding, for instance, through public or private equity financing or short or long-term debt financing, and/or reduce our operating costs.  Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our long-term liquidity needs and achieve our intended long-term business objectives.

	4.  Basis of Presentation
	The accompanying unaudited financial statements for the period ended September 30, 2013 were 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.  Operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or future years.  All normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the financial condition and results of operations have been included.
	The year-end 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.  These interim financial statements should be read in conjunction with our latest Annual Report on Form 10-K for the year ended December 31, 2012.

	5.   Accounting Policies
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an unrecognized tax benefit when a net operating loss (“NOL”) carry-forward, a similar tax loss, or tax credit carry-forward exists.” ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a NOL carry-forward, a similar tax loss, or a tax credit carry-forward when settlement in this manner is available under the tax law. This guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are evaluating the potential impact of ASU 2013-11 on our financial statements.
	There have been no other changes in accounting policies from those stated in the Annual Report on Form 10-K for the year ended December 31, 2012.

	6.   Loss per Common Share
	Basic loss per common share is determined based on the weighted-average number of common shares outstanding during each period.  Diluted loss per common share is the same as basic loss per common share as all common share equivalents are excluded from the calculation, as their effect is anti-dilutive. The weighted average number of common shares outstanding for the three months ended September 30, 2013 and 2012 were 90,960,883 and 78,814,429, respectively.  The weighted average number of common shares outstanding for the nine months ended September 30, 2013 and 2012 were 87,609,393 and 73,686,528 respectively.
	Options and warrants to purchase 9,390,058 and 10,467,563 shares of common stock were outstanding at September 30,  2013 and 2012, respectively.  In addition, unvested restricted stock units (“RSUs”), representing 960,553 and 1,472,968 shares of common stock, were outstanding at September 30, 2013 and 2012, respectively.   These options, warrants and RSUs were excluded from the computation of diluted loss per common share as their effect would have been anti-dilutive.

	There has been no material change in the assumptions used to compute the fair value of our equity awards, nor in the method used to account for share-based compensation from those stated in our Annual Report on Form 10-K for the year ended December 31, 2012.
	The following table presents share-based compensation expense included in our statements of comprehensive loss for the three and nine months ended September 30, 2013 and 2012, respectively:
		Three months ended					Nine months ended
		September 30,					September 30,
			2013		2012		2013		2012
	Research and development expense	$	334,937	$	267,397	$	1,039,778	$	429,057

	General and administrative expense		606,611		595,228		3,799,430		1,839,280
	Total share-based expense	$	1,012,331	$	941,267	$	5,053,848	$	2,384,865
	As of September 30, 2013, we had approximately $4.7 million in unrecognized compensation cost, net of estimated forfeitures, related to unvested share-based compensation awards.  This cost is expected to be recognized over a weighted average period of approximately  1.4 years.
	In November 2011, we issued 800,000 RSUs  to a consulting firm as a performance incentive in connection with a services agreement. These RSUs vested only upon achievement of certain market conditions, as measured based on the closing price of our common stock during a period ending on the earlier of (i) December 31, 2013 or (ii) thirty days following termination of the related consulting agreement.  The issuance of the RSUs and the underlying shares is exempt from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended (the “Securities Act”).    As of June 30, 2013, all of  these RSUs had vested based on achievement of relevant market conditions.  The fair market value of the vested RSUs is measured based on the closing price of our common stock on the date of vesting.  For the three and nine months ended September 30, 2013, we recognized expense related to these RSUs of approximately $0 and $1,836,000, respectively which is included in general and administrative expense in the table of share-based compensation above.

	9.   Stock Authorization and Issuance
	On August 6, 2013, we completed the sale of an aggregate of 3,681,573 shares of our common stock, at a price of $3.80 per share, to a limited number of domestic institutional and other accredited investors in a private placement transaction pursuant to Rule 506 of Regulation D under the Securities Act of 1933, as amended.   The offering represented 4.0% of our outstanding common stock on an after-issued basis.   The aggregate net proceeds from this offering, after deduction of placement agent fees and other offering costs which are recorded to additional paid in capital in the accompanying balance sheets, were approximately $13.0 million.  We filed a registration statement on August 21, 2013 to register the resale of the common stock issued in the private placement transaction.  The registration statement became effective on September 18, 2013 (File No. 333-190769).  In the event the registration statement ceases to be effective for any continuous period that exceeds 10 consecutive calendar days or more than an aggregate of fifteen calendar days during any 12-month period or any time during the six-month anniversary of the registration date (a “Registration Default”), we shall pay the investors an amount in cash equal to 1% of the aggregate purchase price paid for each 30-day period of a Registration Default.   The maximum penalty that we may incur under this arrangement is 6% of the aggregate purchase price, or $839,399 subject to reduction for shares sold or transferred and not held at the penalty determination date.  We do not believe that payment under the registration payment arrangement is probable and therefore no related liability has been recorded in the accompanying financial statements.
	On March 26, 2013, we completed the sale of an aggregate of 4,715,000 shares of our common stock, at a price of $3.25 per share, in an underwritten offering with Ladenburg Thalmann & Co. Inc. as underwriter.  The offering represented 5.4% of our outstanding common stock on an after-issued basis.  The aggregate net proceeds from this offering were approximately $14.3 million, after deduction of underwriting discounts and commissions and other offering costs which are recorded to additional paid in capital in the accompanying balance sheets,.  The offering was made pursuant to our shelf registration statement on Form S-3 filed with the SEC on September 4, 2012 (File No. 333-183713) which was declared effective on September 11, 2012, covering up to $25 million of our securities, and our registration statement on Form S-3 filed with the SEC on March 21, 2013 (File No. 333-187403), which became effective immediately upon filing pursuant to Rule 426(b) under the Securities Act, covering approximately an additional $2.5 million of our securities.  As of March 31, 2013, there were no additional securities available for issuance under these registration statements.
	During the three and nine months ended September 30, 2013, we issued 398,328 and 758,394 shares of our common stock upon the exercise of warrants issued in connection with the sale of equity securities for proceeds of approximately $508,000 and $771,000, respectively.  These proceeds are included in the accompanying statements of cash flows.

	Legal Proceedings
	In addition to the legal proceedings described below, from time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business.  We believe, based upon advice from outside legal counsel, that the final disposition of such matters will not have a material adverse effect on our financial position, results of operations or liquidity.
	ParkerVision vs. Qualcomm, Inc.
	On October 17, 2013, a jury in the United States District Court of the Middle District of Florida delivered its verdict in the first phase of our patent infringement litigation against Qualcomm.  The jury found Qualcomm liable of both direct and indirect infringement of all eleven claims of our four patents asserted in this case for all Qualcomm accused products.  In addition, the jury found that Qualcomm had not proven any of the eleven patent claims to be invalid.  On October 24, 2013, the same jury returned its verdict in the second phase of this litigation, awarding us $172.7 million in past damages for Qualcomm’s infringement.  The jury found that we did not prove our claims of willfulness, which would have allowed the judge to enhance the jury-awarded damages.
	The parties have a number of post-trial motions and briefs to be filed, including our request for an injunction against Qualcomm, or alternatively, ongoing royalties for future infringing sales by Qualcomm.  Based on a joint schedule filed with the court in November 2013, we expect to file, by December 2, 2013, a motion for injunction or ongoing royalties, as well as a motion for pre-and-post judgment interest and costs.  In addition, the parties have agreed to a deadline of December 20, 2013 for filing any additional judgment as a matter of law briefings or new trial motions, with responses to such motions filed by January 24, 2014.  The court will then enter a final judgment after ruling on these outstanding motions.  We do not know at this time when the court will rule on these outstanding motions or enter a final judgment.  The amount and timing of the collection of damages from Qualcomm is dependent upon final disposition of the litigation which may include settlement discussions and/or appeals.
	We first filed a complaint against Qualcomm on July 20, 2011, as amended on February 28, 2012, seeking unspecified damages and injunctive relief for infringement of six of our patents related to radio-frequency receivers and the down-conversion of electromagnetic signals (the “Complaint”).  Qualcomm filed an Answer and Counterclaim to our Complaint (the “Counterclaim”) in which Qualcomm denied infringement and alleged invalidity and unenforceability of each of our patents, including claims of patent unenforceability due to alleged inequitable conduct.  Qualcomm also named our long-time patent prosecution counsel, Sterne, Kessler, Goldstein & Fox PLLC (“SKGF”) as a co-defendant in its Counterclaim and further alleged that we aided and abetted SKGF in its alleged breach of fiduciary duty to Qualcomm and tortiously interfered with Qualcomm’s contractual relationship with SKGF.  Qualcomm also filed a motion to dismiss our claims of indirect patent infringement.  In March 2013, the court denied Qualcomm’s motion to dismiss.
	In November 2011, as amended in April 2012, we filed a motion to dismiss Qualcomm’s Counterclaims related to inequitable conduct, aiding and abetting, and tortious interference, and a motion to strike certain of Qualcomm’s affirmative defenses.  SKGF also filed a motion to dismiss Qualcomm’s claims against them.  In November 2012, the court granted SKGF’s motion and dismissed these claims without prejudice; and furthermore, the court abated Qualcomm’s Counterclaims against SKGF such that Qualcomm is unable to file an amended Counterclaim against SKGF until such time that the court lifts the abatement.
	In January 2013, the court dismissed with prejudice two of the three theories Qualcomm asserted in support of its claims of inequitable conduct.  The court also dismissed without prejudice and abated the aiding and abetting and tortious interference claims against us that related to the claims against SKGF that were dismissed.  Furthermore, Qualcomm’s affirmative defenses of inequitable conduct and unclean hands were stricken by the court.  In April 2013, Qualcomm filed an amended Counterclaim which dropped the remaining claims against us that relate to inequitable conduct.
	The court held a non-adversarial technology tutorial in July 2012 and a claim construction hearing in August 2012 where we and Qualcomm presented our respective arguments for the proposed construction of disputed claim terms.  On February 20, 2013, the court issued its claim construction ruling in which the court adopted our interpretation for approximately ninety percent of the key terms in dispute.
	In May 2013, we filed a motion for summary judgment of no invalidity which was granted in part and denied in part in August 2013.   Qualcomm also filed a motion for partial summary judgment in May 2013 to remove certain identified products from the case and to eliminate our claims of induced and contributory infringement for four of the six patents in the case.  Qualcomm’s motion for summary judgment was granted in part and denied in part by the court in August 2013.
	In July 2013, both parties filed motions to disqualify certain of the opposing party’s expert testimony (“Daubert Motions”).  The court heard arguments regarding the Daubert Motions on September 24, 2013, and on October 11, 2013, during the first phase of the trial, the court granted in part and denied in part each party’s respective Daubert Motions.   In August 2013, Qualcomm filed a motion to split the trial proceedings into two phases.  In September 2013, the court granted this motion in part, agreeing to try the issues of infringement and invalidity in the first phase and the issues of willfulness and damages in a second phase with the same jury.  Also in September 2013, in order to narrow the scope of the trial proceedings, we reduced our complaint to eleven claims and four patents and also reduced the number of accused products.
	Maxtak Capital Advisors LLC vs. ParkerVision
	On December 28, 2011, Maxtak Capital Advisors LLC, Maxtak Partners LP and David Greenbaum (the “Plaintiffs”) filed a complaint in the United States District Court of New Jersey against us, our chief executive officer, Jeffrey Parker and one of our directors, Robert Sterne, alleging common law fraud and negligent misrepresentation of material facts concerning the effectiveness of our technology and our success in securing customers.  The Plaintiffs are seeking unspecified damages, including attorneys’ fees and costs.  On March 3, 2012, we filed a motion to dismiss and a motion to transfer this case to the Middle District of Florida.  In October 2012, the court granted our motion to transfer the case to the Middle District of Florida.  In May 2013, the court denied our motion to dismiss.  Discovery is ongoing in this case with a discovery cut-off date of July 1, 2014 and a trial date commencing February 2, 2015.  We believe this matter is without merit, and we do not believe it is probable that this case will have a material adverse effect on our financial position, results of operations or liquidity.
