Xiao-I shares jump 18.40% premarket after Supreme People's Court upholds validity of core AI patents in lawsuit against Apple.

Xiao-I Corporation surged 18.40% in premarket trading following a significant legal update in its ongoing patent infringement lawsuit against Apple. On March 27, 2026, China’s Supreme People's Court ruled in favor of Xiao-I, rejecting Apple’s appeal to invalidate the core artificial intelligence patents held by Xiao-I’s variable interest entity. This final and binding ruling affirms the validity of Xiao-I’s patents and strengthens its position in the case, which centers on alleged intellectual property infringement by Apple. While the company cautions that no financial compensation is guaranteed, the favorable judicial outcome has been interpreted by investors as a positive development for Xiao-I’s IP portfolio and its broader AI business strategy.
