In compliance with the Phase One Trade Agreement, China has implemented a patent linkage system in their amended patent law, which became effective June 1, 2021 (Article 76 of the Patent Law of the People’s Republic of China (2020)). The Chinese patent linkage system prevents marketing approval of generic drugs until after the expiration of patents covering the drugs or uses. Specifically, the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) has set up a registration system to register patents covering: chemical drugs and uses; traditional Chinese medicines (TCM) and uses; and biologics: Active Pharmaceutical Ingredients (API) sequence structure and medical use. The registration system started public testing in May and is now live.
The National Medical Products Administration (NMPA), in conjunction with the China National Intellectual Property Administration (CNIPA), recently solicited public comments on the draft of “Measures For the Implementation of Early Resolution Mechanisms for Drug Patent Disputes (Trial)” (“Draft Measures”). The purpose of the Draft Measures is to establish an early resolution mechanism for drug patent disputes. The deadline for submission of comments is October 25, 2020.
