Pendrell Files Suit Against SanDisk over Former Nokia Memory Patents

December 9, 2016

Memory Technologies LLC (MTL), a subsidiary of publicly traded patent investment company Pendrell Corporation, has filed a single lawsuit against Western Digital and its recently acquired SanDisk subsidiary (8:16-cv-02163). The complaint asserts eight patents (8,307,180; 9,063,850; 7,739,487; 7,565, 469; 7,827,370; 7,275,186; RE45,486; RE45,542) from a larger portfolio acquired from Nokia early in 2013. MTL alleges that “as many as 81 of its patents belong to families with patents essential to various memory and electronic storage standards”, including the JEDEC eMMC standard and Secure Digital Association Physical Layer Specification (“SD Standard”). MTL accuses various memory products, including SanDisk SD cards, microSD cards, SanDisk eMMCs (“embedded multimedia cards”), and other products that contain SanDisk eMMCs. MTL also filed an ITC action against SanDisk and Western Digital (337-TA-1034) on the same day that it launched the district court cases, asserting the ‘180, ‘850, ‘186, ‘486, and ‘542 patents against the same types of memory product.
