Sonraí Memory Limited has sued Kingston Technology (8:21-cv-01039) and Western Digital (8:21-cv-01040) over the provision of devices that contain “SanDisk/Toshiba 64L 3D NAND flash chips”, as well as solid state drives (SSDs) that include Silicon Motion SSD controllers (Kingston) or Marvell SSD controllers (Western Digital). These new suits expand a campaign that started in February of this year with Western District of Texas cases against Alphabet (Google), LG Electronics (LGE), and Samsung and that proceeded with separate additional suits filed against Apple, Dell, and Kioxia in April, also in West Texas. The new litigation, by contrast, has been filed in the Central District of California.
Roughly a month after a “Scramoge, Ltd.” accused Samsung of infringing three former LG Innotek patents, generally related to wireless power transfer, Scramoge Technology Limited has filed suit against Apple (6:21-cv-00579) over patents from the same portfolio. Scramoge again claims infringement through the wireless charging functionality in various products, this time including AirPods, Apple Watches, and iPhones, in a complaint also filed in the Western District of Texas.
In February, RPXflagged the assignment of over 120 US patent assets from LG Innotek to Irish entity Scramoge Technology Limited, also noting the assignee’s ties to a group of Irish NPEs backed by the hedge fund Magnetar Capital. Now, a similarly named plaintiff has asserted three of those patents against Samsung (6:21-cv-00454) in a new Western District of Texas complaint, alleging infringement through the provision of various “sub-models” of the Galaxy smartphone. The patents-in-suit generally relate to wireless charging.
