SK hynix Inc., commonly known as SK hynix, is a leading South Korean semiconductor company headquartered in Icheon, Gyeonggi-do, South Korea. The company was founded in 1983 as Hyundai Electronics, eventually becoming part of the SK Group in 2012. As a public entity, it trades on the Korea Exchange (KRX: 000660) and has American Depositary Shares (SKHY). SK hynix is one of the world's largest memory chip manufacturers, with approximately 34,737 employees as of March 2026, though some reports indicate employee counts exceeding 45,000. The company reported revenues of $91.71 billion USD (TTM) as of 2026.
SK hynix specializes in designing, developing, and manufacturing a variety of semiconductor memory products. Its core offerings include Dynamic Random-Access Memory (DRAM) chips and NAND flash memory chips, making it one of the "Big Three" global memory manufacturers alongside Samsung and Micron. Key product lines encompass computing memory (for desktops, servers, laptops), mobile memory, graphics memory, consumer and network memory, CMOS image sensors, and Solid-State Drives (SSDs). A significant focus is on High Bandwidth Memory (HBM), which it supplies to major customers like Nvidia for AI accelerators and high-performance computing systems, holding a substantial share of the global HBM market.
Based on the provided data, SK hynix's patent litigation posture is that of an operating company defending against patent assertions. The company has one tracked case, in which it is named as a defendant and has zero plaintiff cases. The sole tracked case occurred in the U.S. District Court for the Western District of Texas.
The notable tracked case for SK hynix is Netlist Inc. v. SK hynix, filed on June 15, 2020. This specific litigation forms part of a longer-standing patent dispute between Netlist and SK hynix concerning server memory modules. While an ITC judge initially found infringement by SK hynix in 2019, the full International Trade Commission later reversed this finding in April 2020, determining no infringement occurred. Ultimately, SK hynix settled its patent dispute with Netlist in April 2021, entering into a patent cross-licensing agreement that included royalty payments of approximately $40 million.
Netlist Inc. sued SK hynix for patent infringement concerning US10217523B1. A Markman hearing took place, and the trial was pending before the case was stayed.
