Company overview. SanDisk Corp. (now styled "Sandisk Corporation," Nasdaq: SNDK) is a NAND flash memory and data storage company headquartered at 951 Sandisk Drive, Milpitas, California. The business was founded in 1988 as SunDisk and reincorporated as Sandisk Corporation in 2024 as part of its separation from Western Digital, which had acquired SanDisk in 2016 for roughly $19 billion. Western Digital spun off the flash business on February 21, 2025; SNDK began trading on Nasdaq on February 24, 2025. It is a standalone public company (no parent), reporting about 11,100 employees and roughly $20 billion in trailing-twelve-month revenue in recent filings. CEO is David V. Goeckeler.
Products / operations. Sandisk designs and manufactures flash storage: solid-state drives (client, gaming, and enterprise/datacenter eSSDs), removable memory cards (SD/microSD), USB flash drives, embedded flash for smartphones, PCs, automotive, IoT and industrial applications, plus wafers and components sold to OEMs and datacenters. Manufacturing is tied to its long-running joint ventures with Kioxia (formerly Toshiba Memory) in Yokkaichi, Japan. It is an operating company, not an NPE.
Patent-litigation posture. Across tracked data, SanDisk appears in one case, as plaintiff only (1–0), in the Northern District of California before Judge William Alsup. That is not the profile of a serial assertor or a pure defendant; it is an operating company that litigates defensively, concentrated in its home district rather than plaintiff-friendly venues such as the Eastern District of Texas.
Notable case. SanDisk Corp. v. LSI Corp. (N.D. Cal., filed June 19, 2009). SanDisk sought declaratory judgment of non-infringement and invalidity of eight LSI patents (MPEG/video and audio decompression, memory architecture) after LSI sent infringement letters to SanDisk customers over its media players, and added state claims for unfair competition, interference, and trade libel. Judge Alsup dismissed the state law claims as preempted by federal patent law in September 2009; the action was dismissed with prejudice in March 2010. The case reflects the consumer-media-player era of SanDisk's business, not its current NAND/SSD portfolio.
