Request for priority considered withdrawn (2) If the applicant fails to comply with the requirements of paragraph (1)(a) or (b) in respect of a previously regularly filed application for a patent not later than four months after the date of the notice referred to in subsection (1), the request for priority is considered to have been withdrawn at the end of that time in respect of that previously regularly filed application unless, before the end of that time, (a) a request is made to the patent office where the previously regularly filed application was filed to provide the copy and certificate referred to in paragraph (1)(a); and (b) the applicant submits to the Commissioner a request that the Commissioner restore the right of priority on the basis of that previously regularly filed application and a statement indicating the patent office to which the request referred to in paragraph (a) was made and the date of that request. Applicant considered to comply (3) If the conditions set out in paragraphs (2)(a) and (b) are met by the applicant in respect of a previously regularly filed application for a patent, the applicant is considered to have complied with subsection (1) in respect of that application. Submission of copy and certificate (4) If the conditions set out in paragraphs (2)(a) and (b) are met in respect of a previously regularly filed application for a patent and if the patent office where that application was filed provides the copy and certificate referred to in paragraph (1)(a), the applicant or the patentee, as applicable, must submit the copy and certificate to the Commissioner not later than three months after the day on which they were provided. Request for priority considered withdrawn (5) If the applicant or patentee fails to comply with subsection (4) in respect of a previously regularly filed application for a patent, the request for priority is considered to have been withdrawn at the end of the time referred to in that subsection in respect of that application. Exception (6) Subsections (1) to (5) do not apply in respect of a previously regularly filed application on the basis of which an applicant requests priority if the pending category 3 application is a PCT national phase application or a divisional application resulting from the division of a PCT national phase application and if the requirements of Rule 17.1(a), (b) or (b- bis ) of the Regulations under the PCT are complied with in respect of that previously regularly filed application.
