40 cases as defendant.
Samsung Electronics America, Inc. is the United States-based sales, marketing, and distribution subsidiary of Samsung Electronics Co., Ltd., a South Korean multinational electronics and technology corporation. Headquartered in Ridgefield Park, New Jersey, Samsung Electronics America (SEA) was incorporated in 1983. As a wholly owned subsidiary of the publicly-traded Samsung Electronics Co., Ltd. (KRX: 005930), it is a major component of the parent company's global operations, which reported consolidated revenues of approximately $230 billion in 2025 and employs over 262,000 people worldwide.
As an operating company, SEA markets and sells a wide portfolio of consumer and enterprise products in the United States. Major product lines include mobile devices (Galaxy smartphones, tablets, and wearables), home entertainment (TVs, projectors, and sound devices), and home appliances (refrigerators, laundry machines, and vacuums). The company also provides business technology solutions, including digital displays and 5G network systems. Beyond its sales and marketing role, SEA is involved in research and development through entities like Samsung Research America, Inc.
The provided data shows Samsung Electronics America is overwhelmingly a defendant in patent litigation, with 9 out of 10 tracked cases filed against it. This posture is typical of a large operating company defending its products against patent assertions. The lawsuits are frequently filed in plaintiff-friendly jurisdictions, particularly the U.S. District Court for the Eastern District of Texas. The plaintiffs in these cases, such as Lepton Computing LLC, Gaea, LLC, Topwire LLC, Malikie Innovations Limited, and Monticello Enterprises LLC, are often characterized as non-practicing entities (NPEs) or patent assertion entities.
The litigation against Samsung often targets core features of its high-volume products. For instance, recent cases from Lepton Computing concern foldable smartphone technology central to Samsung's Galaxy Z series. Malikie Innovations, which acquired a large portfolio from BlackBerry, has sued over patents related to mobile communications. In one instance, Samsung has acted as a plaintiff, filing a proceeding at the Patent Trial and Appeal Board (PTAB) against Topwire LLC, likely a defensive measure to challenge the validity of a patent being asserted against it.
Lepton Computing LLC alleges that Samsung's Galaxy Z Fold and Z Flip series smartphones infringe on nine patents related to foldable technology, including US 11,693,450. The plaintiff is seeking both monetary damages and a permanent injunction to halt sales of the accused devices.
