Defendant
1 case as defendant.
Tridonic GmbH & Co KG is a global supplier of lighting technology and a subsidiary of the publicly traded Zumtobel Group. Headquartered in Dornbirn, Austria, the company was founded in 1956. For the 2022/23 fiscal year, Tridonic generated sales of €367 million and employed 1,687 people.
As the technology arm of the Zumtobel Group, Tridonic develops, manufactures, and markets components for professional lighting systems. Its main product lines include LED modules, LED drivers, emergency lighting units, sensors, and lighting control systems. The company provides intelligent hardware and software for scalable, networked lighting solutions, enabling applications for the "Internet of Light" for customers such as lighting manufacturers, building managers, and system integrators. Their products are used in various settings, including offices, retail, industrial, and outdoor lighting.
Based on the provided litigation data, Tridonic’s posture is that of an operating company defending its technology. The company has been named as a defendant in one patent case and has not been tracked as a plaintiff. This pattern is typical of a technology manufacturer being targeted by a patent assertion entity, rather than an entity that actively asserts its own patents in court.
The single tracked case, Modulus Systems LLC v. Tridonic GMBH & Co KG, was filed on April 22, 2026. The suit was filed in the U.S. District Court for the Eastern District of Texas, a venue frequently used for patent infringement lawsuits. The plaintiff, Modulus Systems LLC, has filed similar patent infringement complaints against other technology companies in the same jurisdiction.
The accused products are radio frequency modules and the methods they use to transmit and receive data.
