China’s Supreme People’s Procuratorate Publishes 5 IP Cases Using Tech Tools
China’s Supreme People’s Procuratorate released five IP cases applying technical tools in IP prosecutions.
Why it matters: IP lawyers working on China-related enforcement or cross-border litigation should monitor China’s integration of technology in legal procedures. These cases clarify evidentiary standards and technical applications setting precedents for multinational IP disputes.
- Five IP cases published by China’s Supreme People’s Procuratorate on September 2, 2026.
- Cases illustrate technical support use in patent infringement, trade secret protection, copyright technological measures, internet dissemination, and network crime identity verification.
- Compiled by the SPP’s Intellectual Property Procuratorial Department and Procuratorial Technology and Information Research Center.
- Highlighted trade secret case involves Zhejiang Enmo Innovation Technology vs. ex-employee Li, who stole technical data to join competitor Suzhou SiXX Transmission Equipment.
The cases address critical technical issues across multiple IP areas, including:
- Determining patent infringement through technical analysis
- Proving non-public-knowledge status for trade secrets
- Identifying technological protection measures under copyright law
- Characterizing 'deep linking' as dissemination over information networks
- Verifying identities in network-related crimes
One significant case involves Zhejiang Enmo Innovation Technology Co., Ltd., which developed specialized capacitive coupling wireless transmission technology for CT slip rings and enforced strict confidentiality measures. Employee Li illicitly transferred detailed technical drawings and data to a USB drive before resigning to join Suzhou SiXX Transmission Equipment Co., Ltd., a competitor. The case illustrates how technical details and internal safeguards bear on trade secret theft prosecutions.
Aaron Wininger, author at China IP Law Update, commented, "These cases reflect recent efforts by procuratorial organs to accurately apply technical expertise in intellectual property cases." The publication guides procuratorial bodies nationwide to leverage technology for effective, precise enforcement.
Additional official context and analysis can be found via the Supreme People’s Procuratorate official site. Legal professionals dealing with China’s IP landscape and multinational enforcement should closely watch these developments. The enhanced use of technical evidence signals a shift in China’s legal standards, impacting global IP litigation strategies.
