China's supreme court bans Infineon from selling GaN power chips in China — market-leader Innoscience secures major victory in multi-region patent war
China's Supreme People's Court has ruled in favor of Innoscience, prohibiting Infineon from selling its gallium nitride (GaN) power chips in mainland China. This decision stems from a patent infringement case where Infineon was found to have violated two Innoscience patents and ordered to pay damages. The ruling is part of a broader, multi-jurisdictional patent dispute between the two companies, both of which are key suppliers for Nvidia's next-generation AI server power systems. While Innoscience secured a victory in China, Infineon had previously won an import and sales ban against Innoscience in the U.S. based on a different patent infringement. AI
IMPACT This ruling could disrupt supply chains for AI hardware and intensify competition among GaN chip manufacturers.
