Description of Business	'
	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.

Liquidity and Going Concern [Abstract]	'
Liquidity and Going Concern	'
	2.  Liquidity and Going Concern
	Our financial statements were prepared assuming we would continue as a going concern, which contemplates that we will continue in operation for the foreseeable future and will be able to realize assets and settle liabilities and commitments in the normal course of business.  These financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that could result should we be unable to continue as a going concern.
	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 securing product and licensing customers for our technologies, successfully supporting our customers in completing their product designs, and/or successfully protecting or defending our intellectual property.
	We expect that revenue, if any, for 2014 will not be sufficient to cover our operational expenses for 2014, and that our expected continued losses and use of cash will be funded from available working capital.  In addition, we expect that a portion of available working capital will be used for litigation expenses to defend our intellectual property.  Our current capital resources include cash and available for sale securities of approximately $17.0 million at September 30, 2014.  These current capital resources may not be sufficient to support our liquidity requirements for the next twelve months and beyond without additional financing or cost containment measures that, if implemented, may jeopardize our future growth plans.  These circumstances raise substantial doubt about our ability to continue as a going concern.  We believe we may be able to meet future liquidity needs through contingent litigation or other financing, or through the issuance of equity securities, although there can be no assurance that such financing will be available to us.  We currently have no significant long-term debt obligations.
	The long-term continuation of our business plan beyond 2014 is dependent upon the generation of sufficient revenues from our technologies and/or products to offset expenses.  In the event that we do not generate sufficient revenues, we will be required to obtain additional funding through public or private financing and/or reduce 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.

	3.  Basis of Presentation
	The accompanying unaudited financial statements for the period ended September 30, 2014 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, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 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, 2013.

	4.   Accounting Policies
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update 2013-11 Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”) to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists thereby reducing diversity in practice. The amendments in ASU 2013-11 became effective for the Company on January 1, 2014 and did not have a material impact on our financial statements.
	In August 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” (“ASU 2014-15”)  to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures.  ASU 2014-15 is effective for interim and annual periods beginning after December 15, 2016 and earlier adoption is permitted.  We are currently assessing the impact of this update on future discussions of our liquidity position in 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, 2013.

Loss Per Common Share	'
	5.   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, 2014 and 2013 were 97,017,009 and 90,960,883, respectively.  The weighted average number of common shares outstanding for the nine months ended September 30, 2014 and 2013 were 95,918,402 and 87,609,393, respectively.
	Options and warrants to purchase 7,765,232 and 9,390,058 shares of common stock were outstanding at September 30, 2014 and 2013, respectively.  In addition, unvested restricted stock units (“RSUs”), representing 2,309,901 and 960,553 shares of common stock, were outstanding at September 30, 2014 and 2013, 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.

	7.  Share-Based Compensation
	On June 17, 2014, our shareholders approved amendments to our 2011 Long-Term Equity Incentive Plan (the “2011 Plan”) including an increase to the shares authorized for issuance under the plan from 5,000,000 to 12,000,000 shares.  Upon approval of the amendments to our 2011 plan, we also amended our 2000 Performance Incentive Plan (the “2000 Plan”) such that no further awards will be granted under the 2000 Plan.
	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, 2013.
	The following table presents share-based compensation expense included in our statements of comprehensive loss for the three and nine months ended June 30, 2014 and 2013, respectively:
		Three months ended					Nine months ended
		September 30,					September 30,
			2014		2013		2014		2013
	Research and development expense	$	199,165	$	334,937	$	932,649	$	1,039,778

	Total share-based expense	$	690,168	$	1,012,331	$	3,961,342	$	5,053,848
	As of September 30, 2014, we had approximately $1.5 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  one year.
	For the nine months ended September 30, 2014 and 2013, share-based compensation expense above includes approximately $683,000 and $1,836,000, respectively, recognized upon vesting of RSUs awarded to consultants.  As of September 30, 2014, we have an aggregate of 440,000 time-based RSUs and 750,000 performance-based RSUs awarded to consultants that remain unvested.  An aggregate of 480,000 time-based RSUs were awarded to a consultant in August 2014 as payment for services.  The RSU vests in twelve equal monthly increments and the shares underlying the RSU are unregistered.  The performance-based RSUs, awarded in November 2013, vest 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, 2015 or (ii) thirty days following termination of the related consulting agreements.  Upon thirty days’ notice, the consulting agreements may be terminated and any unvested portion of the time-based or performance-based RSUs will be cancelled.

	8.   Stock Authorization and Issuance
	On March 13, 2014, we completed the sale of an aggregate of 2,666,666 shares of our common stock, at a price of $4.50 per share, to two 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 2.8% of our outstanding common stock on an after-issued basis.   The aggregate net proceeds from this offering, after deduction of offering costs which are recorded to additional-paid-in-capital in the accompanying balance sheets, were approximately $11.9 million.  We filed a registration statement on April 7, 2014 to register the resale of the common stock issued in the private placement transaction.  The registration statement became effective on May 1, 2014 (File No. 333-195105).  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 approximately $720,000 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.

	Legal Proceedings
	From time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business.   We believe, based on advice from our outside legal counsel, that the final disposition of such matters will not have a material adverse impact on our financial position, results of operation or liquidity.   In addition, we are subject to the following legal proceedings:
	ParkerVision vs. Qualcomm, Inc.
	On July 20, 2011, we filed a patent infringement action in the United States District Court of the Middle District of Florida against Qualcomm Incorporated (“Qualcomm”) seeking unspecified damages and injunctive relief for infringement of several of our patents related to radio-frequency receivers and the down-conversion of electromagnetic signals.  Qualcomm filed a counterclaim against us alleging invalidity and unenforceability of each of our patents.  In October 2013, a jury awarded us $172.7 million in damages for Qualcomm’s direct and indirect infringement of eleven claims of four of our patents.  The jury also found that Qualcomm did not prove its claims of invalidity for any of the eleven claims of the four patents in the case, and furthermore found that we did not prove our claims of willfulness, which would have allowed enhancement of the jury-awarded damages.  On June 20, 2014, a final district court ruling was issued in which the court denied Qualcomm’s motion to overturn the jury’s verdict regarding validity of the patents but granted Qualcomm’s motion to overturn the jury’s verdict of infringement.   On June 25, 2014, we filed a notice of appeal with the court to appeal the decision of non-infringement to the U.S. Court of Appeals for the Federal Circuit.  We filed our opening brief with the appellate court on September 15, 2014 and Qualcomm’s response and opening brief is due to be filed by November 20, 2014.  No date has yet been set for a hearing by the U.S. Court of Appeals. The collection of damages from Qualcomm in this action, if any, will be dependent upon the final disposition of this case.
	ParkerVision vs. Qualcomm, HTC, and Samsung
	On May 1, 2014, we filed a complaint in the United States District Court of the Middle District of Florida against Qualcomm, Qualcomm Atheros, Inc., HTC Corporation and HTC America, Inc. seeking unspecified damages and injunctive relief for infringement of seven of our patents related to RF up-conversion, systems for control of multi-mode, multi-band communications, baseband innovations including control and system calibration, and wireless protocol conversion. On August 21, 2014, we amended our complaint adding Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., and Samsung Telecommunications America, LLC (collectively, “Samsung”) as defendants as well as four additional patents to this case.  The parties are required to file a case management report with the court by December 8, 2014.
	RPX and Farmwald vs. ParkerVision
	In June 2014, RPX Corporation and Michael Farmwald (collectively, the “Petitioners”) filed petitions for Inter Partes review (“IPR”) with the Patent Trial and Appeal Board of the United States Patent and Trademark Office (“PTAB”) seeking to invalidate certain claims related to three of the four patents in our July 2011 district court case against Qualcomm.  In July 2014, the Petitioners filed an additional IPR petition seeking to invalidate certain claims of the fourth patent in the July 2011 district court case against Qualcomm.  On September 24, 2014 and October 10, 2014, we filed our preliminary responses to these petitions with the PTAB.  The PTAB will make a determination as to whether or not to institute IPRs within six months of the filing date.
	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 were seeking unspecified damages, including attorneys’ fees and costs.  In October 2012, the court granted our motion to transfer the case to the Middle District of Florida where discovery commenced.
	In July 2014, we conducted a demonstration of our d2p technology for the Plaintiffs.  As a result of the demonstration and the discovery conducted to date, the parties entered into a confidential resolution of this action.  In connection with the resolution, the Plaintiffs stated that they agree and acknowledge that the d2p technology works in a manner consistent with our representations during the period covered by the litigation.  The Plaintiffs further agreed and acknowledged that their allegations with regard to the efficacy of the d2p technology and all statements in their complaint attributed to or based upon the pvnotes website, Michael Farmwald, Barbara Paldus, Alfred Riddle, Steven Cripps and Joy Laskar with regard to the efficacy of our d2p technology are without merit.  The financial terms of the confidential resolution will have no impact on our financial position, results of operations or liquidity.

Recent Accounting Pronouncements	'
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update 2013-11 Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”) to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists thereby reducing diversity in practice. The amendments in ASU 2013-11 became effective for the Company on January 1, 2014 and did not have a material impact on our financial statements.
	In August 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” (“ASU 2014-15”)  to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures.  ASU 2014-15 is effective for interim and annual periods beginning after December 15, 2016 and earlier adoption is permitted.  We are currently assessing the impact of this update on future discussions of our liquidity position in our financial statements.
