Recently, an administrative dispute over the invalidation of an invention patent right, in which Jiangsu NICO Medical Devices Co., Ltd. was the third party in the first instance and was jointly represented by Beijing Sanju Sunshine Intellectual Property Agency Co., Ltd. and Beijing Yiju Law Firm, has been finally settled. The Supreme People's Court made the (2023) Supreme People's Court Intellectual Property and Administrative Affairs Final 475 administrative judgment, dismissing Medtronic Inc.'s appeal and upholding the (2022) Beijing 73 Administrative 13741 judgment made by the Beijing Intellectual Property Court.

In the above-mentioned judgment, the Beijing Intellectual Property Court rejected Medtronic Inc.'s lawsuit and upheld the invalidation review decision No. 55824 made by the National Intellectual Property Administration, which declared all of Medtronic Inc.'s invention patent rights for "Removable Combined Thrombus Device Aggregates" invalid.

Medtronic Inc. had previously sued Jiangsu NICO and others for infringing this invention patent right and demanded 5 million yuan in compensation. However, after the patent was declared invalid and the invalidation review decision was upheld twice by the courts, Medtronic Inc.'s infringement lawsuit no longer had a legal basis.

Sanju Sunshine and Yiju Law Firm also jointly represented Jiangsu NICO in other patent invalidation proceedings and successfully declared Medtronic Inc.'s invention patent rights invalid in the corresponding infringement litigation cases. The related cases have received attention from various provincial and municipal authorities and media in Jiangsu Province.
