China's supreme court ruled against Infineon's GaN power chips in the country, handing a major patent-infringement victory to domestic chipmaker Innoscience in a multi-region litigation. The ban restricts Infineon's market-leading position in gallium nitride technology within China's power electronics and EV sectors.
The ruling reflects rising protectionism in semiconductor IP and signals Innoscience's strategy to lock in Chinese high-power applications. For supply-chain leaders, expect accelerated substitution toward domestic GaN suppliers in China's industrial and automotive segments.
