North Star Sweeps Canon and Microsoft into Expanded Campaign, Asserting Patents Acquired from Freescale
Wi-LAN Inc. (WiLAN) subsidiary North Star Innovations Inc. has added Canon (1:16-cv-00651) and Microsoft (1:16-cv-00655) to its steadily expanding semiconductor, mobile device, and media hardware campaign, accusing the two companies of infringing multiple combinations of three patents acquired in October 2015 from Freescale before its acquisition by NXP Semiconductors in December 2015. Both are alleged to infringe a single patent (5,892,777, issued in 1999 to Motorola) that generally relates to memory circuit design and architecture. Canon is also accused of infringing another patent (6,903,004, issued in 2005 to Freescale) generally related to forming semiconductor layers with low K dielectrics, with the memory and image processor chips found in its consumer and DSLR cameras alleged to infringe both the ‘777 and ‘004 patents. Microsoft, meanwhile, is also targeted over an additional patent (5,893,752, issued in 1999 to Motorola) generally related to forming semiconductor layers using multiple conductive films. The Microsoft products at issue include its Surface Pro 4 tablet and Xbox One console.
