North Star Moves Infringement Claims Against UMC from Delaware to California

  • September 22, 2016

In May 2016, North Star Innovations Inc., a subsidiary of publicly traded Wi-LAN, Inc. (WiLAN), filed a single case (1:16-cv-00368) accusing both Cypress Semiconductor and UMC of infringing a semiconductor fabrication patent (5,961,373) through the manufacture and sale of memory devices made via a CMP (chemical-mechanical polish) process using an Applied Materials tool. Both defendants filed motions to dismiss for lack of personal jurisdiction over them in Delaware. North Star responded by opposing Cypress’s motion and by dismissing the claims against UMC without prejudice. The NPE has now filed a standalone case (8:16-cv-01721) against UMC, again asserting the ‘373 patent, but this time in the Central District of California.
