Recently, the Shenzhen Intermediate People’s Court rendered the first-instance judgment in a patent infringement dispute for a well-known domestic smart toy enterprise. Acting as counsel for the plaintiff, the Liu Shen team secured a favorable first-instance ruling through rigorous strategy formulation, comprehensive evidence collection, and compelling courtroom advocacy.
The plaintiff is a leading original design enterprise in the smart toy sector with high market recognition and an outstanding industry reputation. During the product design phase, the Liu Shen team assisted the client in constructing a robust patent portfolio, building a solid IP protection barrier and effectively mitigating the risk of malicious copying of innovative achievements.
After the official launch of the client’s products, Liu Shen further initiated patent infringement litigation against typical malicious copycat acts. During the proceedings, the asserted patent endured more than six invalidation challenges. Nevertheless, the Liu Shen team successfully maintained the patent validity and achieved a complete victory in the infringement lawsuit.
Notably, the core dispute centered on the claim construction of specific terminologies in the patent claims. Adhering to prudent and efficient trial principles, the judge conducted a thorough review of the oral hearing records from the invalidation proceeding and submissions from both parties, and ultimately found patent infringement in accordance with applicable laws.
Serving as the client’s legal representative in both the infringement litigation and patent invalidation procedures, the Liu Shen team successfully defended the patent against multiple invalidation challenges. By synchronously advancing litigation and invalidation proceedings, the team secured this interim victory and effectively safeguarded the client’s legitimate rights and interests. In addition to this case, Liu Shen has repeatedly represented the same client in analogous disputes and obtained multiple enforceable favorable judgments, including one case with compensation awarded at RMB 2 million. The firm continues to build a solid IP protection shield for domestic innovative enterprises.
The legal team consisted of attorneys CHEN Xi, CHENG Chi, LIU Fang, LI Qi and LI Kai. Tailoring strategies to the factual circumstances, the team arranged manpower in a scientific manner, efficiently coordinated multi-proceeding strategies, and conducted in-depth research into evidentiary materials. The team provided professional and efficient legal services and earned high recognition from the client. This achievement not only demonstrates the professional competence and rigorous work ethos of Liu Shen attorneys, but also embodies the firm’s core value of Professionalism and Precision in Technology and Practice. Moving forward, Liu Shen will continue to deepen its expertise in intellectual property legal services and contribute to protecting clients’ legitimate rights and promoting innovative development with high-quality, professional legal support.
