2020-03-11 【Taiwan Patent Law】The major amendments of Taiwan Patent Law in 2019 – Part 4 (entered into force on November 1, 2019)

Main Amendment:

(1) The allowable period for making a post-grant amendment application to utility model patent; and

(2) the requirement of substantive examination

Regarding (1):

Since substantive examinations are not applied for utility model applications, to avoid the claim scope of such patents from being changed after post-grant amendment applications have been approved, thereby affecting a third party’s interests, the timing which a patentee can apply for a post-grant amendment has been revised. Also, substantive examination will be conducted from now on for utility model post-grant amendment application.

(1) During the invalidation is processing:

A request for post-grant amendment application filed prior to the implementation of the amendment of the Patent Law shall be accepted.

A request for post-grant amendment application filed after the implementation of the amendment of the Patent Law shall be accepted only when the Patent Office notifies the patentee to provide a response or a supplementary response or when an earlier-filed request for post-grant amendment is not approvable.

(2) When a post-grant amendment application is filed independently:

A request for post-grant amendment application filed prior to the implementation of the amendment of the Patent Law shall be accepted, and a substantive examination is conducted for the utility model post-grant amendment application.

A request for post-grant amendment application filed after the implementation of the amendment of the Patent Law shall be accepted only when a request for technical evaluation report of the utility model patent is pending or when a litigation case involving the utility model patent is pending, and a substantive examination is conducted for the utility model post-grant amendment application.
