Company profile

Samsung Semiconductor, Inc. is the U.S. subsidiary of South Korea-based Samsung Electronics, Ltd. (KRX: 005930), a multinational electronics and technology corporation. Headquartered in San Jose, California, in a 1.1 million-square-foot campus that opened in 2015, the subsidiary is responsible for R&D and sales operations in the U.S. Samsung Semiconductor is part of Samsung Electronics' broader Device Solutions (DS) Division, which is the company's global semiconductor business. For the first quarter of 2026, the DS Division reported global consolidated revenue of KRW 81.7 trillion.

As an operating company, Samsung Semiconductor's business covers a wide range of industry-leading semiconductor products. Its major business areas are Memory, System LSI, and Foundry services. The Memory division produces DRAM, SSDs, and other flash memory for PCs, data centers, mobile, and automotive applications. The System LSI business designs logic chips such as mobile processors (Exynos), image sensors (ISOCELL), display driver ICs, and power management ICs. The Foundry business provides manufacturing services for a global customer base using advanced process technologies.

The provided data shows Samsung Semiconductor as an active patent litigant, but its posture is primarily that of a large operating company defending its products and technology. The single tracked case is a Patent Trial and Appeal Board (PTAB) proceeding where Samsung is the plaintiff-petitioner, challenging the validity of a patent owned by Netlist, Inc. Filing such actions is a common defensive strategy used by operating companies when accused of infringement. This is consistent with a company that manufactures and sells products being targeted by patent assertion entities.

The tracked case is part of a larger, multi-front patent dispute between Samsung and Netlist, a memory technology company. Netlist has sued Samsung for infringement in U.S. district courts, including the Eastern District of Texas, and at the International Trade Commission (ITC), winning substantial jury verdicts. The PTAB action represents Samsung's counter-maneuver to invalidate one of Netlist's asserted patents. The broader conflict between the two companies also involves a dispute over a breached joint development and license agreement.
