Wi-LAN Inc. (WiLAN) has filed suit against MediaTek (1:17-cv-00554), asserting a single patent (6,359,654) already at issue in the publicly traded NPE’s five-year-old, digital television campaign. The complaint targets MediaTek- and MStar-branded image/video processing chips and chipsets that allegedly implement the “MDDi de-interlacing process” purportedly claimed in the ‘654 patent. WiLAN contends that MediaTek became aware of that patent at least as early as May 2015 because Sharp, a campaign defendant at that time, requested indemnification from MediaTek for the Sharp accused products that incorporated MediaTek chips.
Wi-LAN Inc. (WiLAN) expanded its litigation campaign targeting digital televisions, filing three suits against ON Corporation (1:15-cv-00786), Sansui (1:15-cv-00787), and Vizio (1:15-cv-00788). The complaints against ON and Vizio assert three patents concerning image display (5,847,774; 6,359,654; 6,490,250). Only the ‘654 patent is asserted against Sansui. In all three cases, the defendants’ digital televisions and display components are at issue.
