On June 15, Innoscience (02577.HK) rose 5.29% in regular trading, trading at HK$61.05/share, with turnover of HK$61.28 million. The rally follows a landmark patent litigation victory announced after market close on June 12.

On June 12, China's Supreme People's Court issued a final ruling upholding the Suzhou Intermediate Court's sales injunction against Infineon, effectively banning Infineon's related GaN power semiconductor products from sale, import, or offer for sale in China. The ruling confirmed that Infineon infringed two of Innoscience's core GaN invention patents, ordering immediate cessation of sales and compensation of RMB 10 million. The patent validity was verified through three levels of judicial review including the National Intellectual Property Administration, Beijing IP Court, and the Supreme Court.

The banned Infineon GaN products correspond to an estimated RMB 2.8-3.0 billion annual market in high-margin segments including industrial applications, AI server power supplies, and automotive OBC. Innoscience, already the global leader in GaN power device shipments with over 30% market share, stands to directly benefit from the resulting market share redistribution in China.
