1 case as defendant.
AMS-OSRAM AG (often referred to as ams OSRAM) is an Austrian-German global leader in innovative light and sensor solutions, co-headquartered in Premstätten, Austria, and Munich, Germany. The company was originally founded in 1981, and its current form emerged from the acquisition of German lighting manufacturer OSRAM by ams AG in 2020. AMS-OSRAM AG is a publicly traded company, listed on the SIX Swiss Exchange under the ticker symbol AMS. As of late 2023/early 2026, the company reported approximately 18,500 to 20,378 employees worldwide. Its trailing 12-month revenue as of March 31, 2026, was approximately $3.82 billion, with a market capitalization of $2.61 billion as of May 27, 2026.
AMS-OSRAM AG develops and produces a distinct portfolio of advanced light and sensor technologies, leveraging its expertise in photonics and semiconductor technology. Its operations are primarily divided into two segments: Semiconductors and Lamps & Systems. The Semiconductors segment includes LEDs, lasers, optical and CMOS image sensors, and analog integrated circuits with embedded software. The Lamps & Systems segment focuses on traditional automotive and specialty lamps, as well as LED-based lighting modules. These products serve a variety of end markets, including automotive, industrial, medical, and consumer electronics, with applications such as in-cabin sensing, 3D sensing, dynamic automotive lighting, and LiDAR systems.
In terms of patent litigation, AMS-OSRAM AG primarily operates as a defendant, indicating a posture of defending its products and technologies against assertions. The company has no record as a plaintiff in tracked patent litigation cases. It has been involved in one tracked case as a defendant, which took place before the Patent Trial and Appeal Board (PTAB).
The most notable recent case involving AMS-OSRAM AG is Greenthread LLC v. Cirrus Logic, Inc. et al., initiated on October 12, 2023, at the Patent Trial and Appeal Board. This single case suggests that AMS-OSRAM AG is an operating company that defends against patent challenges, often involving patent validity at administrative bodies like the PTAB, rather than actively asserting patents in district courts.
This Inter Partes Review (IPR) proceeding was filed by Cirrus Logic, Inc. and other entities against patent owner Greenthread LLC challenging US patent 10734481, and it resulted in a Final Written Decision.
