When You Cannot Compare the Code: The SPC's RMB 166 Million Centrifuge Case and How to Prove Data Misappropriation Without the Defendant's Data
AnJie Broad partner Li Yanying reads (2022)最高法知民终1592号, the 'centrifuge case' — selected as one of the SPC's 2025 typical anti-unfair-competition cases on 8 September 2025 — for what it teaches about the burden of proof when the misappropriated asset is data. The plaintiffs never obtained the defendants' software or dataset, never decompiled anything, and never ran a substantial-similarity comparison. Instead they exploited the input-output character of software: enter the claimed impeller basic-stage data into their own program along with performance figures taken from the defendants' published product literature, and the output matched. Under AUCL Article 39(2)(i) that was enough to shift the burden, and the defendants' refusal to permit on-site inspection or produce design files converted into an adverse inference. DCC adds the correction the commentary omits: the SPC did not protect the software as a trade secret at all — the plaintiffs failed to delimit its secret points, so it was rejected on the not-generally-known element, and only the dataset was protected. The software was the measuring instrument, not the asset. For overseas counsel holding datasets in China, this is the enforcement route that actually carries damages, and the case is a lesson in how to delimit a claim before you file.

China's First 'AI Hallucination' Tort Judgment — GenAI Is a Service, Not a Product, and the Chatbot's '¥100,000 Promise' Binds No One
The Hangzhou Internet Court has decided China's first 'AI hallucination' (AI幻觉) tort case — written into the Supreme People's Court's 2026 work report to the NPC. A user asking a chatbot about college applications was told, across seven rounds, that a non-existent campus existed; when finally shown the official website, the model 'apologised' and 'promised' to pay ¥100,000, even generating a fake lawsuit template telling him to sue. He did. The court dismissed every claim and, in doing so, laid down the first judicial articulation of China's generative-AI liability framework: (1) an AI model is not a civil subject, so its 'promise' is no declaration of intent — and is not attributable to the provider either; (2) generative AI is a service, not a product, so fault liability under Civil Code Article 1165 applies, not product liability's no-fault rule under Article 1202; (3) there is no result-based duty to guarantee accuracy for ordinary inaccurate output — only a process duty of care (conspicuous AI-content labelling plus industry-standard accuracy measures), which the provider had discharged; and (4) no proven damage, no causation. For any company deploying GenAI to the Chinese public, this is the operating liability surface and the evidentiary playbook.

Datatang v. Yinmu — China's First Ruling on a Data-IP Registration Certificate, and Why Open-Sourced Data Is Still Protected
A consolidated case study of 数据堂诉隐木科技 (Datatang v. Yinmu) — the Beijing IP Court's June 2024 appeal ruling, widely called China's first case on the evidentiary effect of a data-IP registration certificate. The dispute: Datatang built voice datasets for AI training, open-sourced some under a license; Yinmu took and redistributed them in the same data-services market. DCC synthesizes four commentaries (the case report, a Tsinghua analysis, and two Shenzhen Data Exchange DEXC+ deep-dives) into the four holdings that matter for overseas counsel: (1) a data-IP registration certificate is prima facie evidence of property-type interests and lawful sourcing — but not an absolute property right (property-rights-statutism); (2) open-sourced data, though neither trade secret nor copyrightable compilation, is protectable under the Anti-Unfair Competition Law's general clause; (3) the protection hierarchy (compilation work → trade secret → AUCL Art. 2); and (4) whether the taker honored the open-source license is the hinge for 'improper conduct.'
