The second-instance case of trade secret infringement represented by lawyer Zhiheng was successfully reversed in the Supreme People's Court and achieved a comprehensive victory
Recently, the case of Dongguan Company A against Shenzhen Company B and Liu for infringement of trade secrets, represented by lawyer Li Weixiang and lawyer Zhou Xiaojie of
, won the final judgment of the Supreme People's Court.


This case is a difficult and complex case involving infringement of technical secrets, involving disputes in judicial practice such as "whether the non-public element is established" in trade secret cases, "how to evaluate the relationship between secrecy and patent novelty", and "how to correctly understand and apply Article
32of the Anti-Law".
After careful and rigorous case analysis and argumentation by lawyer Zhiheng, the Supreme Court finally adopted our representative opinion, and finally determined that the other party constituted trade secret infringement, and bore the legal consequences of stopping infringement and compensating for losses. It revoked the first-instance judgment and corrected our victory, becoming one of the few typical cases of trade secrets directly withdrawn by the Supreme Court.
In the litigation game between clients and competitors, lawyer Zhiheng provides clients with an overall rights protection plan involving patent infringement, patent ownership disputes, professional inventions and creations, and trade secret infringement. This case is a key case in the overall rights protection plan. So far, lawyer Zhiheng has won a series of rights protection cases for clients and helped clients effectively protect their rights.
This comprehensive victory is another major victory at the highest court level in the intellectual property field of Zhiheng after the "Card X" trademark infringement case was rated as the national guiding case of the Supreme People's Procuratorate in 2019, which fully reflects Zhiheng's first-class professional level in the field of intellectual property dispute resolution and the ability to handle complex disputes.
Zhiheng lawyers will continue to improve their professional capabilities and service capabilities, and provide clients with better and more efficient comprehensive solutions.
