Company overview. SK hynix America Inc. is a California corporation headquartered at 3101 North First Street, San Jose, California, and the U.S. operating subsidiary of South Korea's SK hynix Inc. (KRX: 000660), the world's second-largest memory-chip maker and part of the SK Group conglomerate. Its U.S. business dates to 1983, when it operated as the local arm of Hyundai Electronics; it was rebranded SK hynix America in 2012 (SK hynix newsroom). SK hynix Inc. reported roughly ₩97.1 trillion (~US$68 billion) revenue for FY2025 with on the order of 34,000–47,000 employees group-wide; market cap was reported around US$286 billion (Wikipedia; GlobalData; stockanalysis.com). Separate figures for SK hynix America alone are not published.
Products / operations. SK hynix America is a sales, marketing, and customer-support organization for its Korean parent's memory products—DRAM, NAND flash, and SSDs, including high-bandwidth memory (HBM) used in AI accelerators—and has added R&D functions, launching NAND Development America in San Jose in late 2023 (SK hynix newsroom). It is a genuine operating company, not a patent-holding shell. Its parent manufactures memory chips at fabs in Korea and China.
Patent-litigation posture. The tracked docket shows a two-way dispute with Netlist, Inc.: SK hynix America was a defendant in Netlist, Inc. v. SK hynix Inc. et al. (C.D. Cal., Santa Ana Division, filed Aug. 31, 2016) and a petitioner alongside SK hynix Inc. and SK hynix Memory Solutions Inc. in SK hynix Inc. et al. v. Netlist, Inc. (PTAB IPR, filed Dec. 30, 2016). This profile matches an operating company defending against a patent-infringement suit while challenging the asserted patents at the PTAB, rather than an NPE pattern (one defendant case, one plaintiff case).
Notable context. The CDCA suit (8:16-cv-01605) concerned Netlist patents covering RDIMM/LRDIMM server memory modules and ran parallel to ITC Investigation 337-TA-1023 and later SK hynix IPR petitions (e.g., IPR2018-00362/00363) against Netlist's '907 patent. Press and analyst reporting indicate the parties settled and cross-licensed in 2021, with SK hynix paying roughly $40 million plus per-unit royalties under a multi-year agreement that reportedly expired in April 2026 (Nasdaq.com). No specific merits are assessed here.
