Description Of Business [Abstract]
Description Of Business	 1. Description of Business  ParkerVision (“we”or the “Company”) is in the business of innovating fundamental wireless technologies and products. We design, develop and market our proprietary radio frequency (“RF”) technologies for use in semiconductor circuits for wireless communication products, including our own internally developed products. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan includes enforcement of our intellectual property rights through patent infringement litigation and licensing efforts.

Liquidity And Going Concern [Abstract]
Liquidity and Going Concern	2. Liquidity and Going Concern  Our accompanying condensed consolidated 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 consolidated f inancial 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.  We have incurred significant losses from operations and negative cash flows in every year since inception and have utilized the proceeds from the sales of our equity securities and contingent funding arrangements with third-parties to fund our operations, including the cost of litigation. For the three months ended March 31, 2017, we incurred a net loss of approximately $4.8 million and negative cash flows from operations of approximately $4.1 million. At March 31, 2017, we had an accumulated deficit of approximately $357 million and working capital of $5.6 million. These circumstances raise doubt about our ability to continue to operate as a going concern within one year following the issue date of these condensed consolidated financial statements.  At March 31, 2017 , we had cash, cash equivalents, and available-for-sale securities of approximately $5.9 million and restricted cash equivalents of approximately $ 0.8 million. We used approximately $4 .1 million of cash for operations during the three months ended March 31, 2017. We anticipate an increase in our operating and inventory costs in 2017 as we prepare for the launch of a consumer Wi-Fi product line. We anticipate revenues and margin generated by this consumer product will begin to offset our operating costs in the third quarter of 2017, however it is unlikely that the revenues and margins generated in the short-term will be sufficient to fully fund our operations without the need for additional working capital.  Our ability to meet our liquidity needs for the next twelve months is dependent upon (i) our ability to develop, market and sell existing and new products; (ii) our ability to successfully negotiate licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations; and/or (iii) our ability to obtain additional debt or equity financing . We expect that revenue generated from product sales, patent enforcement actions, and technology licenses over the next twelve months may not be sufficient to cover our working capital requirements . In the event we do not generate sufficient revenues to cover our operational costs and contingent repayment obligations, we will be required to use available working capital and/or raise additional working capital through the sale of equity securities or other financing arrangements. We expect to continue to invest in patent prosecution and enforcement, product development, and sales, marketing, and customer support for our technologies and products. The long-term continuation of our business plan is dependent upon the generation of sufficient revenues from our technologies and/or products to offset expenses and contingent payment obligations. In the event that we do not generate sufficient revenues, we will be required to obtain additional funding through public or private debt or equity financing or contingent fee arrangements and/or reduce operating costs. Failure to generate sufficient revenues, raise additional capital through debt or equity financings or contingent fee arrangements, and/or reduce operating costs will have a material adverse effect on our ability to meet our long-term liquidity needs and achieve our intended long-term business objectives.

Basis Of Presentation [Abstract]
Basis Of Presentation	3. Basis of Presentation  The accompanying unaudited consolidated financial statements for the period ended March 31, 2017 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 months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 201 7 or future years. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. A ll normal and recurring adjustments which, in the opinion of management, are necessary for a fair statement of the financial condition and results of operations have been included.  The year-end consolidated balance sheet data was derived from audited financial statements for the year ended December 31, 2016 , but does not include all disclosures required by accounting principles generally accepted in the United States of America. These interim consolidated financial statements should be read in conjunction with our latest Annual Report on Form 10-K for the year ended December 31, 201 6.  The condensed consolidated financial statements include the accounts of ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively, “ParkerVision”) after elimination of all intercompany transactions and accounts.

Accounting Policies [Abstract]
Accounting Policies	4. Accounting Policies  There have been no changes in accounting policies from those stated in our Annual Report on Form 10-K for the year ended December 31, 2016, except as follows:  Recent Accounting Pronouncements  In February 2016, the FASB issued ASU 2016-02 “Leases,” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We are currently assessing the impact of this update on our consolidated financial statements. We have identified all existing operating and financing leases and are in the process of determining the present value of existing lease assets and liabilities under the new guidance. We are also currently formalizing processes and controls to identify, classify and measure new leases in accordance with ASU 2016-02. The impact of ASU 2016-02 on our consolidated financial statements is currently being evaluated .  In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. ASU 2015-14, “Revenue from Contracts with Customers (Topic 606)”, issued in August 2015, defers adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. We do not expect the adoption of ASU 2014-09 to have a material effect on our consolidated financial statements.

Loss Per Common Share [Abstract]
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.  Options and warrants to p urchase 1,116 ,696 and 1,472,401 shares of common stock were outstanding at March 31, 2017 and 2016, respectively. In addition, unvested restricted stock units (“RSUs”), representing 245,000 and 208 shares of com mon stock were outstanding at March 31, 2017 and 201 6 , 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.

Secured Contingent Payment Obligation [Abstract]
Secured Contingent Payment Obligation	8. Secured Contingent Payment Obligation  Our secured contingent payment obligation represents the estimated fair value of our repayment obligation to Brickell Key Investments (“BKI”) under a February 2016 funding agreement, as amended in May 2016. Under the agreement, we received aggregate proceeds of $13 million in exchange for BKI’s right to reimbursement and compensation from gross proceeds resulting from patent enforcement and other patent monetization actions.  BKI is entitled to priority payment of 100% of proceeds received from all patent-related actions until such time that BKI has been repaid in full. After repayment of the funded amount, BKI is entitled to a portion of remaining proceeds up to a specified minimum return which is determined as a percentage of the funded amount and varies based on the timing of repayment. In addition, BKI is entitled to a pro rata portion of proceeds from specified legal actions to the extent aggregate proceeds from those actions exceed the specified minimum return.  BKI holds a senior security interest in our assets until such time as the specified minimum return is paid, in which case, the security interest will be released except with respect to the patents and proceeds related to specific legal actions . The security interest is enforceable by BKI in the event that we are in default under the agreement which would occur if (i) we fail, after notice, to pay proceeds to BKI, (ii) we become insolvent or insolvency proceedings are commenced (and not subsequently discharged) with respect to us, (iii) our creditors commence actions against us (which are not subsequently discharged) that affect our material assets, (iv) we, without BKI’s consent, incur indebtedness other than immaterial ordinary course indebtedness, or (v) there is an uncured non-compliance of our obligations or misrepresentations under the agreement. As of March 31, 2017 , we are in compliance with our obligations under this agreement.  We have elected to measure our secured contingent payment obligatio n at fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods. The secured contingent payment obligation is remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved. As of March 31, 2017 , the fair value of the obligation is estimated to be $14,018,029 (see Note 11).

The following table presents share-based compensation expense included in our condensed consolidated statements of comprehensive loss for the three months ended March 31, 2017 and 2016 , respectively:     Three Months Ended  March 31,  2017 2016  Research and development expenses $ 245,052 $ 26,480  Selling, general and administrative expenses 418,104 8,849  Total share-based compensation expense $ 663,156 $ 35,329   As of March 31, 2017 , we had approximately $863,000 in unrecognized compensation cost related to unvested share-based compensation awards. This cost is expected to be recognized over a weighted average period of approximatel y one year .

Stock Authorization And Issuance [Abstract]
Stock Authorization And Issuance	10 . Stock Authorization and Issuance  On November 14, 2016, we filed a Shelf for the offering of various securities, up to $15 million, over a period of up to three years. The Shelf, which was declared effective November 30, 2016, is intended to provide flexibility for our future capital needs and may be used to fund working capital, capital expenditures, vendor purchases, and other capital needs. On December 30, 2016, we entered into an At Market Issuance Sales Agreement (“ATM”) for the sale of up to $10 million of our common stock registered under the Shelf. During the three month period ended M arch 31 , 2017, we complet ed the sale of approximately 4.1 million shares of our common stock under the ATM at an average price of $2.46 per share for net proceeds of approximately $9.6 million after deduction of broker commissions, legal fees and expenses .  In February 2017 , we received proceeds of approximately $170,000 from the sale of 80,510 unregistered shares of our common stock at a price of $2.11 per share to one of our directors .  Stock for Services  During the three months ended March 31, 2017 , we issued an aggregate of 300,000 shares of unregistered common stock to two consultant s in exchange for an aggregate of $425,000 in prepaid retainer s for executive consulting and other advisory services. We have no registration obligation with respect to these shares.

Fair Value Measurements	11 . Fa ir Value Measurements  The following table s summarize the fair value of our assets and liabilities measured at fair value on a recurring basis as of March 31, 2017 and December 31, 2016 :       Fair Value Measurements  Total Fair Value Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3)  March 31, 2017:  Assets:  Money market funds $ 540,646 $ 540,646 $ - $ -  Restricted money market funds 839,933 839,933 - -  Available-for-sale securities 4,815,182 4,815,182 - -  Liabilities:  Secured contingent payment obligation $ 14,018,029 - - $ 14,018,029      Fair Value Measurements  Total Fair Value Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3)  December 31, 2016:  Assets:  Restricted money market funds $ 910,838 $ 910,838  Available-for-sale securities 13,618 13,618  Liabilities:  Secured contingent payment obligation $ 14,185,447 $ - $ - $ 14,185,447   For the three months ended March 31, 2017, we had no transfers of assets or liabilities between the levels of the hierarchy. The fair value of our contingent payment obligation was estimated using a probability-weighted income approach based on various cash flow scenarios as to the outcome of patent-related actions both in terms of timing and amount, discounted to present value using a risk-adjusted rate. The contingent payment obligation does not have a fixed duration; however our cash flow projections assume a remaining duration ranging from approximately one to four years. The cash outflows could potentially range from $0 to $32 million through 2021 and the cash flow scenarios have probabilities of 0% to 30% . We used a risk-adjusted discount rate of 15.93% , based on a five year risk-free rate of 1.93% as adjusted by 8% for credit risk and 6% for litigation inherent risk. Changes in any of these Level 3 inputs could result in a higher or lower fair value measurement. The following table provides a reconciliation of our secured contingent payment obligation for the three months ended March 31, 2017 :       Secured Contingent Payment Obligation  Balance at December 31, 2016 $ 14,185,447  Repayment -  Change in fair value (167,418)  Balance at March 31, 2017 $ 14,018,029

Commitments And Contingencies [Abstract]
Commitments And Contingencies	12 . Commitments and Contingencies  Lease Commitments  In April 2017, we entered into a new lease agreement for our Lake Mary, Florida facility. The lease term is expected to commence July 1, 2017 and provides for a straight-lined monthly base rental payment of approximately $11,900 through November 2022 with an option for renewal.  Legal Proceedings  From time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business. These proceedings include patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us at the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office (“PTAB”) in an attempt to invalidate certain of our patent claims. These patent-related proceedings are more fully described below. Although there is at least a reasonable possibility of an unfavorable outcome in any one or more of these matters, we believe that any such outcome is not expected to have a material im pact on our financial position or results of operation s .  ParkerVision vs. Qualcomm and HTC (Middle District of Florida) We have a patent infringement complaint pending in the Middle District of Florida against Qualcomm, Qualcomm Atheros, Inc., and HTC (HTC Corporation and HTC America, Inc) (the “Qualcomm Action”) seeking unspecified damages and injunctive relief for infringement of certain of our patents . Certain of the defendants have filed counterclaims against us for non-infringement and invalidity for all patents in the case. A claim construction hearing was held in August 2015 but no ruling on claim construction has been issued by the court. In February 2016, the court granted the parties’ joint motion to stay these proceedings until resolution of the proceedings at the International Trade Commission (“ ITC ”) as discussed below. In May 2017, we filed a motion to continue the stay of these proceedings pending an appeal of certain PTAB decisions with regard to our ‘940 Patent as discussed below.  Qualcomm Inc. and Qualcomm Atheros, Inc. vs. ParkerVision (PTAB) In August 2015, Qualcomm, Inc. and Qualcomm Atheros, Inc. filed an aggregate of ten petitions for Inter Partes Review (“IPR”) with the PTAB seeking to invalidate certain claims related to three of the eleven patents originally asserted in our Qualcomm Action. In March 2016, the PTAB issued decisions denying institution of trial for three of the petitions, all of which relate to our U.S. patent 7,039,372 (“the ‘372 Patent”) . The remaining petitions , all of which relate to our U.S. patent 6,091,940 (the ‘940 Patent”) and U.S. patent 7,966,012 (“the ‘012 Paten t”) were instituted for trial by the PTAB. In May 2016, the PTAB granted our motion to disclaim the challenged claims of the ‘012 Patent and entered an adverse judgment against us with respect to those claims. In March 2017, the PTAB issued its decision s on the six outstanding IPRs, all of which relate to the ‘940 Patent. The PTAB ruled in our favor on three of the six petitions, ruled in Qualcomm’s favor on two of the six petitions and issuing a split decision on the claims covered in the sixth petition. As a result of the PTAB decisions, certain claims of our ‘940 Patent which are the subject of our district court case against Qualcomm and HTC were found to be unpatentable. In May 2017, we filed our notice of appeal of these decisions with the Federal Circuit.  ParkerVision v. Apple, LG and Qualcomm (ITC and Middle District of Florida) In December 2015, we filed a complaint with the U.S. I TC against Apple, Inc., LG (LG Electronics, Inc., LG Electronics U.S.A., Inc., and LG Electronics MobileComm U.S.A., Inc.) (collectively LG), Samsung (Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., and Samsung Semiconductor, Inc.) and Qualcomm alleging that these companies make, use or sell products that infringe certain of our patent claims and requesting that the ITC bar the defendants from continuing to import and sell infringing products in the U.S. We filed a corresponding patent infringement complaint in the Middle District of Florida against these same defendants alleging infringement of four of our patents. In January 2016, the ITC instituted an investigation based on our complaint. In February 2016, the district court proceedings were stayed pending resolution of the proceedings at the ITC. In July 2016, we entered into a confidential patent license and settlement agreement with Samsung and, as a result, Samsung has been removed from both the ITC and the related district court action. In January 2016, we dismissed three of the four patents from the case in order to simplify the investigation. On March 10, 2017, the administrative law judge (ALJ) issued a ruling on a pre-trial motion that precluded us from presenting key evidence in our case. As a result, on March 13, 2017, we filed a motion to terminate the proceedings at the ITC. On April 28, 2017, the ITC granted our motion to withdraw from the ITC proceedings. Accordingly, on May 4, 2017, we filed a motion to lift the stay in the district court case. The court has not yet ruled on this motion.  ParkerVision v. LG Electronics (Munich, Germany) In June 2016, we filed a complaint in Munich Regional Court against LG Electronics Deutschland GmbH, a German subsidiary of LG Electronics, Inc. (“LGE”) seeking damages and injunctive relief for the alleged infringement of one of our German patents. A hearing in this case was held in November 10, 2016. On November 14, 2016, the court concluded that certain LGE products using Qualcomm RF circuitry infringe our patent. Subject to successful completion of the co-pending nullity action in the German Federal Patent Court in Munich, the regional court will enjoin the sale and importation of these LG products in Germany. The court has not yet ruled on the nullity action, which is a validity only challenge.  ParkerVision v. Apple (Munich, Germany) In October 2016, we filed a complaint in Munich Regional Court against Apple, Inc., Apple Distribution International, and Apple Retail Germany B.V. & Co. KG (collectively, “Apple”) seeking damages and injunctive relief for the alleged infringement of the same German patent as in the LGE case (the “Apple I” case) . In February 2017, we amended our complaint adding the infringement of a second German patent and alleging infringement by Apple devices that incorporate an Intel transceiver chip. The Munich Regional Court has bifurcated the new claims into a second case separate from the original Apple case (the “Apple II” case) . A hearing was held on May 4, 2017 in the Apple I case . The court set a date of June 22, 2017 for its decision in that case. A hearing for the Apple II case is scheduled for June 29, 2017.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements  In February 2016, the FASB issued ASU 2016-02 “Leases,” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. We are currently assessing the impact of this update on our consolidated financial statements. We have identified all existing operating and financing leases and are in the process of determining the present value of existing lease assets and liabilities under the new guidance. We are also currently formalizing processes and controls to identify, classify and measure new leases in accordance with ASU 2016-02. The impact of ASU 2016-02 on our consolidated financial statements is currently being evaluated .  In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. ASU 2015-14, “Revenue from Contracts with Customers (Topic 606)”, issued in August 2015, defers adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. We do not expect the adoption of ASU 2014-09 to have a material effect on our consolidated financial statements.
