ViaSat has filed what appears to be its first affirmative patent litigation in years, accusing Kioxia (6:21-cv-01231) and Western Digital (6:21-cv-01230) of infringing patents generally related to a “flash memory decoder” with an “error detection module” in a pair of Western District of Texas complaints. The plaintiff targets the provision of flash memory products (e.g., flash-based solid state drives) that support error correction coding (ECC) capabilities, pleading that NAND flash is “notoriously error prone” and that “there is substantial value in figuring out how to eliminate or fix flash errors quickly while utilizing as little power as possible”.
