Does Chinese Taipei allow divisional applications?

Yes. Patent applications which involve two or more inventions may be divided into separate divisional applications, at the request of either the TIPO or the applicant. From 1 November 2019 onwards, a divisional application must be filed within three months of receipt of the notice of grant. A divisional application may only be filed before the re-examination decision on the original application has been taken. It is accorded the filing date of the parent application.
