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.
