China’s ban on German chip giant Infineon sparks rally in domestic GaN stocks - South China Morning Post

China’s Supreme People’s Court upheld a lower court injunction against German chip giant Infineon Technologies in a landmark GaN patent dispute, halting the sale of its GaN products in mainland China.... Read original →

The Chinese Supreme Court’s injunction against Infineon isn’t just a patent ruling—it’s a declaration of technological sovereignty. Technically, domestic GaN players like Innoscience will rapidly displace Infineon in 800V EV and AI data center power modules, forcing SiC cost reductions in high-voltage applications. Notably, China’s compound semiconductor focus sidesteps its EUV limitations. Compliance-wise, multinationals now face a new 'localized IP defense' barrier in China, demanding supply chain redesigns to mitigate single-point patent risks. Strategically, Infineon may shift capacity to Southeast Asia but can’t offset its 38% revenue loss from mainland China; meanwhile, firms like CR Micro and Silan will leverage partnerships with NVIDIA to export tailored GaN solutions. Over the next 12–24 months, China’s GaN ecosystem will close the loop from application-driven demand to standard-setting—quietly shifting global pricing power in power semiconductors eastward.
