Selected Cases Handled by Ling Chuang :

Patent Related Cases:

• Representing a domestic client in kitchen equipment industry to win a design patent infringement case. The court ruled in favor of the client and awarded RMB 100,000 compensation. (Beijing IP Court, 2024. The judgement was final as the defendant did not appeal.)

• Representing a renowned French client in luxury automobile industry to entirely invalidate four design patents. (CNIPA, 2021)

• Representing a renowned German client in sportswear industry to entirely invalidate an invention patent and a related utility model patent. (CNIPA, 2021)

• Representing a Beijing based bio-tech company, a patent assignor, to win a patent-related contract dispute before the Supreme People’s Court (SPC) of China. The case was related to a very complex situation where the patent assignor had a contract clause with the patent assignee that the assignee shall not transfer or license the patent to a third party; otherwise, it shall pay penalty to the assignor. Accidentally, when the assignee breached this agreement by transferring the patent to a third party, the patent was invalidated. The SPC overturned the first instance court’s judgement and ruled that the penalty clause is independent from the validity of the patent and should still be honored. This case was selected into Gazette of SPC for its guidance and influence. (SPC, 2020)

• Representing a domestic client in chemical engineering industry to win an invention patent infringement case. The court ruled that the infringement was established and the client was awarded more than RMB 8 million compensation. (Beijing Supreme People’s Court, 2017)

Trademark Related Cases:

• Representing a domestic client to win a trademark infringement and unfair competition case. The court’s ruling acknowledged that the defendant’s unauthorized use of the client’s registered trademark as their business name is an abuse of the client’s exclusive trademark right and formed an unfair competition action. (Yiyuan County People's Court, 2024. The judgement was final as the defendant did not appeal.)

Service Patent Ownership Dispute Cases:

• Representing defendant, a Chinese client in manufacturing sector, to successfully persuade the courts to believe the involved patent is legally owned by the defendant. The first instance court’s judgement (Tianjin No.3 People’s Court, 2021) ruled that the involved design patent is not a service patent. The second instance court’s judgement upheld the ruling. (Tianjin Supreme Court, 2022)

• Representing a Chinese client in environmental technology sector to secure consecutive wins for four service patent dispute cases in both first and second instance courts. The first instance court’s judgement (Beijing IP Court, 2021) ruled that the involved four patents are all service patents and should be returned to the clients. The second instance court’s judgement upheld the ruling. (Beijing Supreme People's Court, 2021)
