North Star Asserts New Patent Against Xilinx, Familiar Patent Against Seiko Epson

  • December 16, 2016

North Star Innovations Inc., a subsidiary of publicly traded NPE Wi-LAN, Inc. (WiLAN), has filed yet more cases asserting former Motorola patents, received from Freescale in a large October 2015 transaction. After dropping a case that asserted two such patents (5,961,373; 6,013,571) against Xilinx (1:16-cv-00773) in early September, North Star has filed a new suit against the company (1:16-cv-01182), alleging that Xilinx infringes a different patent (7,617,437). The ‘437 patent generally relates to error correction; Xilinx is accused of infringement through the provision of certain systems-on-a-chip (SOCs) that utilize error correction code (ECC) memory, including the Zynq UltraScale+ MPSoC. North Star has also filed a new case against Seiko Epson (1:16-cv-01196), asserting a single patent (6,465,743), generally related to ball-grid array (BGA) chip packages, already at issue in earlier cases filed against ASE, Cypress Semiconductor, IDT, and TI.
