Xueshan Technologies Inc., a subsidiary of Quarterhill Inc. (f/k/a Wi-LAN Inc.), has filed a second complaint in the Eastern District of Texas against Renesas (2:23-cv-00091). Five patents received from MediaTek are asserted in this complaint, with infringement allegations targeting a wide array of computing products, including converters, memory protection units, microcontrollers, and processors. The fresh litigation from Xueshan Technologies drops as the ice around litigation in one of Quarterhill’s oldest campaigns, dating back to 2007, has thawed.

The Patent Trial and Appeal Board (PTAB) saw petitions for AIA review filed against a variety of prolific litigants in June 2017, including General Patent Corporation, Intellectual Ventures LLC (IV), Quarterhill Inc. (f/k/a Wi-LAN Inc.), Realtime Data LLC, Uniloc Corporation Pty. Limited, and Xperi Corporation (f/k/a Tessera Holding Corporation). Also in June, the PTAB instituted trial for petitions brought against patents asserted in a variety of sprawling campaigns, including some waged by Acacia Research Corporation, IV, Papst Licensing, Quarterhill, and VirnetX Inc. The Board further issued final decisions throughout June in AIA reviews against patents involved in several notable campaigns, including some waged by Document Security Systems, Inc., Elm 3DS Innovations LLC, Empire IP LLC, and Quarterhill.

Wi-LAN Inc. (WiLAN) has added new lawsuits against LG Electronics (LGE) (3:17-cv-00358) and Lenovo (3:17-cv-00365) to its long-running wireless networking campaign, accusing the two companies of infringing four patents (8,787,924; 8,867,351; 9,226,320; 9,497,743) through various mobile devices and laptops offering LTE connectivity. These newest complaints come roughly five weeks after WiLAN subsidiary Wireless Protocol Innovations, Inc. dismissed its suit against campaign co-defendant ZTE (6:15-cv-00919) in light of an apparent settlement.

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.
