Plaintiff
2 cases as plaintiff.
Ledup Manufacturing Group Ltd. is a privately held company that manufactures and sells LED lighting products. While an affiliated entity, Ledup Technology Co., Ltd., is based in Shenzhen, China, Ledup Manufacturing Group Ltd. maintains a US mailing address in City of Industry, California, and operates through entities like LEDUP AMERICA LLC. Public information on the company's founding year, employee count, and revenue is not available.
Ledup is an operating company that produces a range of LED lighting solutions, with a focus on seasonal and decorative products. Its product lines include Christmas string lights, icicle lights, illuminated artificial trees, and lawn decorations, which are sold through major retailers like Walmart. The company also manufactures portable LED display systems for trade show booths and provides customer support and tutorials for its products through a dedicated website.
The company's patent portfolio is aligned with its products, covering inventions related to LED light assemblies, waterproof controllers, and electrical connectors for artificial trees. In the provided case data, Ledup acts as a patent plaintiff, a posture of enforcement against competitors. With two tracked cases as a plaintiff and none as a defendant, the company is shown asserting its intellectual property. The cases are appeals at the Court of Appeals for the Federal Circuit, which reviews patent-specific decisions from lower courts and the U.S. Patent and Trademark Office.
The two tracked cases are appeals in Ledup Manufacturing Group Ltd v. Seasonal Specialties LLC, initiated in April 2026. These appeals stem from an earlier Inter Partes Review (IPR) proceeding at the Patent Trial and Appeal Board (PTAB), a process where a third party challenges the validity of a patent. The litigation history indicates an ongoing patent dispute between Ledup and competitor Seasonal Specialties LLC, which previously involved a district court case filed in 2023. This conflict takes place within a broader, litigious market for holiday and general LED lighting technologies.
