Wi-LAN, Inc., through its subsidiary North Star Innovations Inc., has filed a second case against Toshiba (1:16-cv-01113) in 2016, again asserting patents (7,171,526; 7,573,416) received from Freescale in a much larger transfer in October 2015. In February of this year, North Star asserted other former Motorola/Freescale patents against Toshiba as part of a larger string of litigation that has now hit two dozen defendants, including Amazon, Canon, Fujitsu, HP, HTC, Microsoft, Sharp, and UMC, among others. The ‘526 patent generally relates to memory controllers and is asserted against Toshiba laptops (e.g. Protégé Z30 Ultrabook Laptop). The ‘416 patent generally relates to signal conversion with low power control and is asserted against Toshiba memory products (e.g. THGBX6T0T8LLFXF 15nm TLC 128 Gbit NAND Flash).
