Infineon expands on Innoscience lawsuit

Infineon seeks a permanent injunction for the infringement of United States patents referring to gallium nitride (GaN) technology owned by Infineon. The patent claims cover core aspects of GaN power semiconductors encompassing innovations that enable performance and reliability of Infineon’s proprietary GaN power transistors.

Already, on 14 March 2024, Infineon filed a patent infringement suit against Innoscience in the United States with the District Court for the Northern District of California. On 4 June 2024, Infineon filed a corresponding lawsuit with the District Court Munich, Germany. Additional lawsuits were filed against distributors of Innoscience in Germany. Furthermore, Infineon successfully filed for a preliminary injunction (court order), which the District Court Munich issued on 12 June 2024. According to this court order Innoscience was obligated to remove all infringing product from their booth at the international power electronics trade show PCIM Europe.

Infineon leads the industry with its GaN patent portfolio, comprising approximately 350 patent families. Infineon’s portfolio of silicon, silicon carbide, gallium nitride power transistors and complementary drivers and controllers was enhanced with the October 2023 acquisition of GaN Systems Inc. The acquisition boosted Infineon’s GaN offering and further expanded its leading position in power semiconductors.
