§ 49 - Appendix T Patent Cooperation Treaty
§ 49ter.2 Restoration of Right of Priority by Designated Office
(a) Where the international application claims the priority of an earlier application and has an international filing date which is later than the date on which the priority period expired but within the period of two months from that date, the designated Office shall, on the request of the applicant in accordance with paragraph (b), restore the right of priority if the Office finds that a criterion applied by it ("criterion for restoration") is satisfied, namely, that the failure to file the international application within the priority period:
(i) occurred in spite of due care required by the circumstances having been taken; or
(ii) was unintentional.
Each designated Office shall apply at least one of those criteria and may apply both of them.
(b) A request under paragraph (a) shall:
(i) be filed with the designated Office within a time limit of one month from the applicable time limit under Article 22;
(ii) state the reasons for the failure to file the international application within the priority period and preferably be accompanied by any declaration or other evidence required under paragraph (c); and
(iii) be accompanied by any fee for requesting restoration required under paragraph (d).
(c) The designated Office may require that a declaration or other evidence in support of the statement of reasons referred to in paragraph (b)(ii) be filed with it within a time limit which shall be reasonable under the circumstances.
(d) The submission of a request under paragraph (a) may be subjected by the designated Office to the payment to it, for its own benefit, of a fee for requesting restoration.
(e) The designated Office shall not refuse, totally or in part, a request under paragraph (a) without giving the applicant the opportunity to make observations on the intended refusal within a time limit which shall be reasonable under the circumstances. Such notice of intended refusal may be sent by the designated Office to the applicant together with any invitation to file a declaration or other evidence under paragraph (c).
(f) Where the national law applicable by the designated Office provides, in respect of the restoration of the right of priority, for requirements which, from the viewpoint of applicants, are more favorable than the requirements provided for under paragraphs (a) and (b), the designated Office may, when determining the right of priority, apply the requirements under the applicable national law instead of the requirements under those paragraphs.
(g) Each designated Office shall inform the International Bureau of which of the criteria for restoration it applies, of the requirements, where applicable, of the national law applicable in accordance with paragraph (f), and of any subsequent changes in that respect. The International Bureau shall promptly publish such information in the Gazette.
(h) If, on October 5, 2005, paragraphs (a) to (g) are not compatible with the national law applied by the designated Office, those paragraphs shall not apply in respect of that Office for as long as they continue not to be compatible with that law, provided that the said Office informs the International Bureau accordingly by April 5, 2006. The information received shall be promptly published by the International Bureau in the Gazette.
