Plaintiff
32 cases as plaintiff.
Samsung Electronics Co., Ltd. is a South Korean multinational electronics corporation headquartered in Suwon, South Korea. Founded in 1969, it is the flagship subsidiary of the Samsung Group. Samsung Electronics is a publicly traded company under the ticker KRX: 005930. The company is a major global enterprise, with an estimated 266,673 employees. For the fiscal year 2024, the company reported revenues of approximately $220.7 billion.
As one of the world's largest technology companies, Samsung Electronics operates two main divisions: Device eXperience (DX) and Device Solutions (DS). The DX division produces a wide array of consumer electronics, including its well-known Galaxy smartphones, tablets, and wearable devices, as well as TVs, projectors, sound devices, and digital home appliances like refrigerators and washing machines. The DS division manufactures electronic components, and is a global leader in semiconductors, producing memory (DRAM and NAND flash), system LSI, and providing foundry services for other companies.
Samsung’s patent litigation profile is primarily that of a large operating company defending itself against infringement allegations. The provided data shows Samsung as a defendant in 11 of 13 tracked cases, a typical posture for a company with a vast product portfolio. Many of these suits are filed in plaintiff-friendly jurisdictions, particularly the U.S. District Court for the Eastern District of Texas. In two instances, Samsung has acted as a plaintiff at the Patent Trial and Appeal Board (PTAB), a common strategy for defendants to challenge the validity of asserted patents.
The case list shows Samsung is frequently targeted by non-practicing entities (NPEs). Several entities appear as repeat plaintiffs against the company, including VB Assets, LLC, Gaea, LLC, and Lepton Computing LLC, all of which have filed suits in the Eastern District of Texas. The two plaintiff-side cases initiated by Samsung are PTAB petitions challenging the validity of patents held by VB Assets, LLC and Topwire LLC, corresponding to defensive actions against lawsuits brought by these entities.
