Legrand France SA is a subsidiary of Legrand SA, a global specialist in electrical and digital building infrastructures. The parent company, Legrand SA, is a publicly traded French industrial group (Euronext: LR) founded in 1865 and headquartered in Limoges, France. As of 2025, Legrand SA employs over 39,600 people worldwide and reported sales of nearly €9.5 billion (approximately $11.3 billion USD trailing twelve months as of March 2026). Its market capitalization was around $45.5 billion as of May 2026.
Legrand France SA, through its parent company, manufactures and distributes a comprehensive range of low-voltage electrical components and digital building infrastructure products. Key product lines include wiring devices like switches and sockets, cable management systems, power distribution solutions, lighting controls and systems, audio/visual equipment, and network infrastructure solutions. The company serves residential, commercial, and industrial markets globally, including specialized solutions for data centers and connected home/building automation (IoT).
In terms of patent litigation, Legrand France SA appears to primarily operate as an operating company defending against patent assertion entities. The company has been involved in one tracked case as a defendant and zero as a plaintiff. This posture is consistent with an operating company targeted by a non-practicing entity (NPE).
The sole tracked case involving Legrand France SA is Stingray IP Solutions LLC v. Bticino SPA et al., filed on June 4, 2021, in the Texas Eastern District Court. Stingray IP Solutions LLC is identified as a patent assertion entity, and the Eastern District of Texas is known as a plaintiff-friendly venue for patent litigation. Bticino SPA is also part of the Legrand Group.
Stingray IP Solutions LLC sued Bticino SPA, Legrand France SA, Legrand SA, and Legrand SNC in the Texas Eastern District Court regarding US patent 6958986.
