Wi-LAN, Inc. (WiLAN) has launched a second litigation campaign asserting patents from the portfolio that it acquired from Infineon/Qimonda last summer. The plaintiff, wholly owned subsidiary Polaris Innovations Limited, asserted six patents (8,207,976; 8,161,344; 7,886,122; 7,405,993; 7,124,325; 6,532,505) against NVIDIA (5:16-cv-00451), further accusing Dell in the same complaint of infringing two of those patents (the ‘122 and ‘976 patents). The products at issue are NVIDIA graphics processors used in combination with GDDR (“graphics double data rate”) memory, and the Dell and NVIDIA computing devices that incorporate them.
