In a filing with the U.S. Securities and Exchange Commission on 20 June 2026, Xiao-i Corporation (Shanghai Zhizhen Intelligent Network Technology, known for its Xiao-i Robot platform) disclosed that on 10 June the Shanghai High People’s Court had rejected all of its claims in case (2020) Hu Zhi Min Chu No. 7. The court found that Apple’s Siri did not infringe Chinese invention patent ZL200410053749.9, covering a “chatbot system”. Zhizhen had sought an injunction and damages originally calculated at RMB 10 billion and later reduced to RMB 5.1 billion, making the dispute one of China’s most closely watched high-value patent cases involving artificial intelligence and consumer electronics. Xiao-i has said it will appeal to the Supreme People’s Court.
The ruling is a reminder that patent validity and infringement are separate questions. In software and AI disputes, the decisive issue is often whether the claimant can prove how the accused system operates internally and map that operation to every relevant claim element. Large damages figures attract attention, but claim construction, technical comparison and access to reliable evidence usually determine the outcome. Companies considering similar litigation should build the evidentiary record around verifiable technical facts from the outset rather than treating an upheld patent as proof of infringement.
