1 case as defendant.
SK Hynix Inc. is a major South Korean semiconductor manufacturer founded in 1983 as Hyundai Electronics. Headquartered in Icheon, South Korea, it is a public company trading on the Korea Exchange (KRX: 000660) and is a part of the SK Group. As one of the world's largest memory chipmakers, the company reported revenues of approximately $25.1 billion in 2023 and employs over 33,000 people.
SK Hynix is an operating company that designs, develops, and manufactures a wide range of semiconductor memory products. Its main product lines include dynamic random-access memory (DRAM), NAND flash memory, and solid-state drives (SSDs). These components are used in a variety of applications, including servers, personal computers, mobile devices, networking equipment, and automotive systems. The company is a key supplier to major technology firms such as Apple, Dell, and HP Inc.
As an operating company, SK Hynix's patent litigation posture is that of a defendant. The provided database shows it has been a defendant in one tracked case and has not appeared as a plaintiff. This litigation pattern is typical for a large technology manufacturer facing assertions from patent-holding entities. The single tracked case was filed in the U.S. District Court for the Eastern District of Texas, a venue known for patent litigation.
The notable case is Advanced Memory Technologies, LLC v. SK Hynix Inc., filed in late 2024. The plaintiff, Advanced Memory Technologies, LLC, has been characterized as a non-practicing entity (NPE). The suit alleges that SK Hynix's DRAM and NAND flash memory modules infringe on several of the plaintiff's patents.
In an amended complaint filed on April 2, 2025, Advanced Memory Technologies, LLC added U.S. Patent No. 8,400,835 to the list of patents allegedly infringed by SK Hynix. A trial in this matter is scheduled to begin on October 5, 2026.
