Lone Star Silicon Ends October Suing UMC

  • New Patent Litigation, Semiconductors

Lone Star Silicon Innovations LLC closed out October with yet another case filed in its semiconductor fabrication campaign, accusing UMC (2:16-cv-01216) of infringing two patents (6,103,611; 6,388,330) already asserted in the campaign as well as one new one (5,973,372). Lone Star targets integrated circuit devices (ICs) made with UMC’s 40nm process node (the NPE providing as “a representative example” ICs manufactured for resale as Xilinx’s XC6VLX130 Virtex-6 FPGA products) or made using its 28nm HLP, 28nm HPCU, 28nm HPCU+ and 28nm uLP process nodes (the “representative example” given being ICs manufactured for resale as Qualcomm’s MDM9625M LTE Modem). With the addition of the ‘372 patent, nine are now at issue, with Lone Star following a bit of a mix-and-match approach to their assertion.
