In 2024, Zhuhai Guanyu initiated a patent infringement lawsuit against CATL New Energy in the Chongqing No. 1 Intermediate People's Court, and CATL entrusted Junzhiquan to invalidate two invention patents (patent number: 201910277718.8, 202110560546.2) of Zhuhai Guanyu.
Recently, the State Intellectual Property Administration issued two "Invalidation Request Review Decisions", and the invention patent No. 201910277718.8 was declared invalid on the grounds of lack of inventiveness. Invention patent No. 202110560546.2 was declared invalid on the grounds that the specification was insufficiently disclosed.
