Affiliate entities Longitude Licensing and Longitude Flash Memory Systems are asserting a group of 13 former SanDisk patents against Apple (6,510,488, 6,763,424, 6,831,865, 6,968,421, 7,012,835, 7,120,729, 7,181,611, 7,224,607, 7,657,702, 7,818,490, 7,970,987, 8,050,095, 8,316,177). This is the first suit from the Longitude entities and it accuses Apple devices that use flash memory systems, including mobile handsets, tablets, and media players, of infringing the patents-in-suit. The dynamic random memory chipsets used in Apple’s devices are manufactured by outside chip vendors, including Micron and SK Hynix. The asserted patents relate to various aspects of flash memory technology. SanDisk assigned the patents, as part of a larger portfolio of 24 patents, to Intelligent Intellectual Property Holdings on August 1, 2013 and retained a security interest in the portfolio. Later than month the patents were transferred to Longitude Flash Memory Systems, under its former name, PS3 Luxco. Longitude Licensing is the exclusive licensee of the patents-in-suit. 9/23, Northern District of California, 3:14cv04275
