ParkerVision, Inc. has continued the 2020 expansion of its long-running wireless communications campaign, this past week adding Western District of Texas suits against Melco Holdings (Buffalo) (6:20-cv-01009) and ZyXEL Communications (6:20-cv-01010). The publicly traded NPE targets the provision of Wi-Fi routers incorporating wireless networking modules with certain chips from MediaTek and Realtek. These latest cases follow earlier 2020 suits filed separately against Hisense, Intel, and TCL Technology, all as ParkerVision continues litigating a 2014 case in the Middle District of Florida against Qualcomm and its customer HTC, in light of which additional suits, against Apple and LG Electronics (LGE) have been stayed.
