In order to bring the relevant stipulations in the Patent Act into agreement with the Acts Regulating Approval of Pharmaceuticals and Pesticide Products in a clearer manner, the Taiwan Intellectual Property Office has published a new guide for applicants filing patent term extensions in accordance with Article 52 of the current Patent Law. This article stipulates that where the practice of an invention patent relating to pharmaceutical or pesticide composition or its manufacturing method is subject to regulatory approval pursuant to other laws and where it takes more than two years after the publication of the patent application to acquire such approval, the patent owner may apply for an extension of the patent term for a period of two to five years within three months from the date of issuance of the first certificate of regulatory approval.
