Supplementary Examination

PCT applications entering the national phase in Singapore

9.55 According to Section 29(1)(d)(i)(B), where the Singapore application is a PCT application for a patent (Singapore) that has entered the national phase in Singapore under section 86(3), the final results of search and examination in the international phase may be used as the basis for supplementary examination. [See Diagram 30]

9.56 Rule 42A(2)(b) codifies that in the case of a PCT application, the IPRP in the international phase (that is IPRP Chapter I or Chapter II) is the final result. If subsequent examinations have been done on the PCT application during its national phase in one or more countries, these are not taken into account in the supplementary examination – the IPRP is still the final result.
