Wireless Protocol Innovations, Inc. (WPI) is picking up where its parent entity, Wi-LAN Inc., left off, adding new defendants and patents to a large and long-running wireless telecommunications campaign. In two separate suits, WPI accuses TCL (6:15-cv-00918) and ZTE (6:15-cv-00919) smartphones of infringing a group of four telecommunications patents, including one patent (6,381,211) that Wi-LAN has asserted in cases against Apple, Alcatel-Lucent, Ericsson, HTC, LG Electronics (LGE), Sierra Wireless, and Sony.
