(a) Any priority document which is submitted to the receiving Office under Rule 17.1(a) shall be transmitted by that Office to the International Bureau together with the record copy or, if received after the record copy has been sent to the International Bureau, promptly after having been received by that Office.
(b) Where the priority document is issued by the receiving Office and the applicant has, not later than 16 months after the priority date, requested the receiving Office under Rule 17.1(b) to prepare and transmit it to the International Bureau, the receiving Office shall, promptly after receipt of such request ("request for priority document") and, where applicable, the payment of the fee referred to in that Rule, transmit the priority document to the International Bureau. Where such request for priority document has been made but the required fee has not been paid, the receiving Office shall promptly notify the applicant that the request for priority document will be considered not to have been made unless the fee is paid not later than 16 months after the priority date or, in the case referred to in Article 23(2), not later than at the time the processing or examination of the international application is requested.

Where the receiving Office fails to notify the International Bureau accordingly within 17 months from the priority date, the receiving Office shall prepare and transmit the priority document to the International Bureau even though the required fee has not been paid by the applicant.
(e) Where a request for priority document has been received by the receiving Office later than 16 months after the priority date, or where such request has, under paragraph (b), been considered not to have been made, the receiving Office shall promptly notify the applicant accordingly, directing attention to the requirements of Rule 17.1(a).
