Recently, the Beijing Intellectual Property Court issued an administrative judgment (2022) Jing 73 Xingchu No.11782, ruling to reject the plaintiff's claim. So far, the administrative dispute over the invalidation of the patent right of “A Lithium-ion Secondary Battery and Its Cathode Active Material” has come to an end.

After accepting the entrustment of the client, the Hengbo team carried out a lot of meticulous preparation work, including successfully pointing out the defects of the other party's evidence and misunderstanding of the technology. In the end, the Beijing Intellectual Property Court ruled to uphold the invalidation decision made by the China National Intellectual Property Administration, helping the client win first instance of the invalidation administrative dispute.
