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.
