Guangdong Zhiheng (Dongguan) Law Firm, Full-time Attorney

Professional Field:

Intellectual property litigation, trademark and patent applications, invalidation and opposition proceedings, civil and commercial litigation and non-litigation legal services, labor disputes, etc.

Classic Cases or Specialized Services:

1. With over ten years of experience in the intellectual property industry, I have handled more than 3,000 patent applications on behalf of numerous companies.

2. Proficient in patent invalidation proceedings; for example, represented a client in filing an invalidation request against Invention Patent No. 20151XX65XX2, entitled “High-Voltage Molding Apparatus,” and successfully obtained a decision invalidating the entire patent, thereby completely eliminating the client’s potential infringement risks.

3. Experienced in patent infringement litigation cases. In a utility model patent infringement case in which we represented the defendant, Guangdong XX Intelligent Manufacturing Co., Ltd., the court accepted our non-infringement defense, successfully dismissing the plaintiff’s claim for RMB 500,000 and providing robust legal protection for the client’s market competitiveness.

4. Provide enterprises with a variety of non-litigation intellectual property services. Such as intellectual property strategy, patent infringement avoidance design, and industry patent analysis reports, among others.

5. Handled multiple administrative enforcement cases; for example, represented a certain equipment company in Guangdong by filing a patent infringement complaint with the Market Supervision Administration, which was successfully resolved, resulting in an order prohibiting the opposing party from manufacturing the infringing products.
