ParkerVision Files Against MediaTek and Realtek for Patent Infringement

Second Infringement Action Filed Against TCL

JACKSONVILLE, FL / ACCESSWIRE / November 11, 2022 / ParkerVision, Inc. (OTCQB:PRKR) announced today that it has filed new complaints in the Western District of Texas against Taiwanese global fabless semiconductor companies, MediaTek Incorporated ("MediaTek") and Realtek Semiconductor Corp. ("Realtek"), for the infringement of four of its U.S. patents. The complaints request jury trials to determine, among other items, the financial damages for the unauthorized use of ParkerVision's wireless patented technologies in semiconductor chips used in Smartphones, WiFi and Bluetooth devices.

ParkerVision has ongoing actions in the Western District of Texas against Intel Corporation, TCL Electronics Holdings Co. Ltd. and affiliated companies ("TCL") and LG Electronics, Inc. ("LGE"), including a second action filed against TCL on November 7, 2022 for the infringement of two additional patents. To date, ParkerVision has settled actions against Japanese wireless networking company Buffalo, Inc., Taiwanese wireless networking company Zyxel Communications Corporation, and, most recently, Chinese SmartTV company Hisense Co. Ltd. and affiliates ("Hisense") through patent license and settlement agreements.

ParkerVision CEO Jeffrey Parker commented, "MediaTek and Realtek are both global suppliers of wireless semiconductors that we believe broadly infringe on ParkerVision's patented technologies. Both companies supply WiFi and Bluetooth chips worldwide. In addition, MediaTek has recently been cited by some as having the largest volume of Smartphone chip shipments worldwide with forecasts that MediaTek will overtake Qualcomm in unit volume as the chip supplier for Smartphones sold in the U.S."

ParkerVision has invested hundreds of millions in R&D and marketing in its patented RF receiver, transmitter, and RF power transmitter technologies to enable ultra-small semiconductor chips to deliver high performance RF wireless communications for mobile telephone standards such as 3G, 4G, and 5G standards, WiFi communications, Bluetooth, Satellite communications and other wireless applications.
