The application procedure of invention patent in Taiwan Province Province is basically the same as that in Chinese mainland, and its process is as follows: patent application, formal examination, early disclosure, substantive examination and patent authorization.
Within three years from the day after the application date, anyone may file an application for substantive examination with the Patent Office, and once the application is filed, it may not be withdrawn; Chinese mainland applicants should pay attention to the fact that it is best to file an application in Taiwan Province Province before the mainland patent application is made public, otherwise it may be revoked.
