Notes to Financial Statements
Nature of Operations [Text Block]	1. ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively “ParkerVision”, “we” or the “Company”), is in the business of innovating fundamental wireless hardware technologies and products. We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits based on those technologies, and we license those technologies to others for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America (“U.S.”) and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others, and therefore the primary focus of our business plan is the enforcement of our intellectual property rights through patent licensing and infringement litigation efforts. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor suppliers, for the infringement of a number of our RF patents. We have made significant investments in developing and protecting our technologies.
