Lone Star Silicon Files Fifth Case, Against SMIC, in Campaign Asserting Former AMD Patents
Lone Star Silicon Innovations LLC seems to be developing a pattern of filing a new lawsuit every two weeks, the latest defendant being SMIC (2:16-cv-01276). The patents at issue (5,973,372; 6,103,611; 6,388,330) are the same three asserted against UMC roughly two weeks ago. A total of nine patents, all generally related to various aspects of semiconductor fabrication, have been asserted in the campaign to date. Lone Star Silicon targets integrated circuit devices (ICs) made with SMIC’s 40nm process (the NPE providing as a “representative example” ICs manufactured for resale as Rockchip’s RK3028A SoC), made using its 28nm PS process (the “representative example” given being ICs manufactured for resale as Qualcomm’s MSM8916 Snapdragon 410 processor), or made with its 28nm HKMG process (no example being given).
