China and Taiwan have recognised priority claims to patent, trademark and plant variety applications that are filed at either the Taiwan Intellectual Property Office (TIPO) or the State Intellectual Property Office of China (SIPO).
China and Taiwan get reciprocal
The priority date, which is the earliest filing date claimed on the counterpart application, may be traced back to the effective date of the agreement between Taiwan and China ie, September 12, 2010.
Taiwanese enterprises/individuals and mainland Chinese enterprises/individuals can now file applications in Taiwan first, and then claim the subsequent application in mainland China for the same priority date, or vice versa.
