Recently, the Supreme People's Court rendered the Administrative Judgment (2023) Zui Gao Fa Zhi Xing Zhong No. 1081 in the case of Appellant Qingdao A Heavy Industry Co., Ltd. v. Appellee Shandong Hanrui Metallurgical Equipment Co., Ltd. and the Original Defendant the National Intellectual Property Administration, involving an invention patent invalidation administrative dispute. The judgment upheld the first-instance decision and ultimately revoked Invalidation Request Examination Decision No. 56357 issued by the National Intellectual Property Administration.

Previously, Shandong A Conveying Equipment Co., Ltd. and Qingdao A Heavy Industry Co., Ltd. initiated infringement lawsuits against Hanrui Company based on seven utility model patents and one invention patent. In response, Hanrui Company filed invalidation requests against these eight patents with the National Intellectual Property Administration respectively. Among them, six utility model patents were invalidated, and the corresponding infringement lawsuits have been ruled to be dismissed. The only invention patent, which is the patent involved in this case, was previously maintained valid by the National Intellectual Property Administration. However, the administrative judgment has now revoked the decision of the National Intellectual Property Administration maintaining the validity of such patent. Beijing Tangsong Yongxin Intellectual Property Agency Co., Ltd. was entrusted by Hanrui Company to act as its agent in the above invalidation cases. Beijing Caihe Law Firm was entrusted by Hanrui Company to act as its litigation agent in the above administrative litigation cases.
