Infineon Technologies AG is a German company that designs and manufactures semiconductor devices, focusing on power systems and Internet of Things (IoT) solutions. Headquartered in Neubiberg, Germany, Infineon was founded on April 1, 1999, as a spin-off from Siemens AG. It operates as a publicly traded company, listed on the Frankfurt Stock Exchange (IFX) and the OTCQX International Premier in the USA (IFNNY). As of 2025-2026, Infineon employs approximately 57,000 people worldwide and reported revenue of around €14.7 billion in fiscal year 2025. Its market capitalization was approximately $110.83 billion USD as of May 2026.
Infineon's product portfolio includes microcontrollers, power semiconductors (based on silicon, silicon carbide, and gallium nitride), sensors, integrated circuits, RF components, and security solutions. These products are integral to various applications across its four main business divisions: Automotive (ATV), Green Industrial Power (GIP), Power & Sensor Systems (PSS), and Connected Secure Systems (CSS). Its semiconductors are used in areas such as engine and transmission control, safety systems in vehicles, industrial electric drives, renewable energy production, power management for consumer electronics and data centers, and secure IoT devices.
In terms of patent litigation, Infineon Technologies AG is an active two-way litigant. The company has appeared as a plaintiff in one case and as a defendant in one case, both involving MOSAID Technologies Inc. This indicates Infineon is an operating company actively defending its technology and asserting its own intellectual property against patent assertion entities (PAEs).
The two tracked cases are Mosaid Technologies Inc. v. Infineon Technologies AG et al., filed in the U.S. District Court for the Western District of Texas, where Infineon is a defendant, and Infineon Technologies Americas Corp. et al. v. MOSAID Technologies Inc., filed at the Patent Trial and Appeal Board (PTAB), where Infineon is a plaintiff. MOSAID Technologies Inc. is recognized as a patent licensing and assertion entity with a significant portfolio in semiconductor memory and logic technologies. While the Western District of Texas is known as a venue for patent litigation, similar cases brought by MOSAID in this district have faced transfer, suggesting a dynamic environment for patent enforcement.
