Recently, the Beijing Intellectual Property Court rendered Administrative Judgment (2022) Jing 73 Xing Chu No. 14391 in the administrative dispute over invention patent invalidation involving Shandong Hanrui Metallurgical Equipment Co., Ltd. (hereinafter referred to as "Hanrui Company"), the National Intellectual Property Administration, and Qingdao a Heavy Industry Co., Ltd. The judgment upheld Hanrui Company's claims, revoked the corresponding invalidation request examination decision made by the National Intellectual Property Administration, and ordered the Administration to issue a new examination decision.

Previously, a Shandong 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. Hanrui Company filed invalidation requests with the National Intellectual Property Administration against these eight patents respectively. To date, six utility model patents have been invalidated, and the corresponding infringement lawsuits have been dismissed. Although the only invention patent was maintained valid by the National Intellectual Property Administration, the aforementioned administrative judgment has revoked the decision maintaining its validity. Beijing Tangsong Yongxin Intellectual Property Agency Co., Ltd. was entrusted by Hanrui Company to act as its agent in the invalidation cases, and Beijing Caihe Law Firm was entrusted by Hanrui Company to act as its litigation agent in the above administrative litigation case.
