Chinese Chip Stocks Surge After Infineon GaN Patent Ban Upheld by Supreme Court
China's Supreme People's Court has upheld an injunction against German chip giant Infineon Technologies, banning the sale of its gallium nitride (GaN) products in mainland China. This decision, which affirmed a lower court's ruling issued in May, led to a significant surge in domestic semiconductor stocks on Monday. The landmark patent dispute is anticipated to reshape the country’s "third-generation" chip sector.

A recent decision by China’s Supreme People’s Court has upheld a lower court's injunction against German chip giant Infineon Technologies, prohibiting the sale of its gallium nitride (GaN) products in mainland China.
The ruling, issued on Friday, confirmed the injunction that was initially issued against the German company in May. This development, which bans Infineon from selling GaN products in the country, triggered a notable spike in domestic semiconductor stocks on Monday.
The patent dispute is widely expected to influence and reshape China’s burgeoning “third-generation” chip sector. The upholding of the injunction against Infineon Technologies was announced via a statement released by domestic rival Innoscience.
According to South China Morning Post, the lower court had previously made findings that led to the injunction against Infineon.
