Achievements

Representative Litigation Cases:

• Represented a medical device enterprise in a trade secret infringement dispute arising from employee job-hopping. As counsel for the defendant, he successfully proved "passive use" of the alleged trade secret, reducing the awarded compensatory damages from over RMB 80 million claimed by the plaintiff to RMB 600,000. This case was selected by the Shanghai High People's Court into three authoritative case collections: 2024 Typical Cases of Intellectual Property Judicial Protection by Shanghai Courts for the Development of New Quality Productive Forces, 2025 Typical Cases of Serving and Guaranteeing Shanghai's Deepening of the Construction of an International Science and Technology Innovation Center, and 2026 Typical Cases of Trade Secret Protection by Shanghai Courts.
• Represented a chemical enterprise in rights protection against a competitor that colluded with suppliers to infiltrate the factory and steal technical secrets. His work included filing a criminal report, coordinating with forensic appraisal institutions to conduct technical secret appraisal, facilitating the public security organ’s criminal case filing and case transfer for examination and prosecution, and representing the victim entity in criminal proceedings with an incidental civil action filed. The first-instance judgment ruled that the defendants bear criminal liability and pay RMB 5 million in civil compensation.
• Represented the defendant in an invention patent infringement dispute involving industrial robot technology and the related patent invalidation proceedings. He filed a request for patent invalidation declaration with the China National Intellectual Property Administration (CNIPA) against the patent in suit, successfully obtained a ruling declaring the patent invalid, and secured a favorable judgment in the subsequent administrative litigation over the patent invalidation decision.
• Represented the defendant in a patent ownership dispute filed by a competitor of a special materials enterprise, who alleged that a job-hopping employee had disclosed its technical secrets. As defense counsel, he pointed out that the technical secrets claimed by the plaintiff were not supported by corresponding carrier evidence, thus negating the basis of the plaintiff’s claim, and eventually forced the plaintiff to withdraw the lawsuit.
• Represented a headhunting company in filing a report with the administrative authority against an employee who illegally scraped the company’s talent database via technical means. He prompted prompt enforcement action by the authority, timely halted the ongoing illegal act, and effectively prevented further damage.
• Represented a domestic industrial equipment manufacturer in a patent infringement dispute with a foreign industry giant. He filed a request for patent invalidation declaration with the CNIPA against the patent in suit, and successfully obtained a ruling invalidating the patent held by the foreign enterprise.
