On June 18, Innoscience (02577.HK) rose 3.57% in regular trading, trading at HK$67.45/share, with turnover of HK$282 million. The stock continues to gain momentum following its landmark patent infringement victory against Infineon.

On June 12, the Supreme People's Court issued a final ruling upholding the Suzhou Intermediate Court's sales ban against Infineon, effectively prohibiting all related GaN products from being sold, offered for sale, or imported within China. Infineon was also ordered to pay RMB 10 million in damages. This marks a decisive win for Innoscience in the patent dispute, with its two core GaN invention patents validated through three levels of judicial and IP review.

The ruling leaves an estimated RMB 2.8–3.3 billion annual market gap in China's high-end GaN segment, particularly in AI server power supplies and automotive-grade applications. As the world's first IDM manufacturer to achieve mass production of 8-inch silicon-based GaN wafers, Innoscience already commands over 30% global market share in GaN power semiconductors. Analysts expect the company to further consolidate its leadership position as GaN adoption accelerates in data centers and humanoid robotics.
