Patent Cooperation Treaty (PCT)

Article 25
Review by Designated Offices

(1)(a)  Where the receiving Office has refused to accord an international filing date or has declared that the international application is considered withdrawn, or where the International Bureau has made a finding under Article 12(3), the International Bureau shall promptly send, at the request of the applicant, copies of any document in the file to any of the designated Offices named by the applicant.

(b) Where the receiving Office has declared that the designation of any given State is considered withdrawn, the International Bureau shall promptly send, at the request of the applicant, copies of any document in the file to the national Office of such State.

(c)  The request under subparagraphs (a) or (b) shall be presented within the prescribed time limit.

(2)(a)  Subject to the provisions of subparagraph (b), each designated Office shall, provided that the national fee (if any) has been paid and the appropriate translation (as prescribed) has been furnished within the prescribed time limit, decide whether the refusal, declaration, or finding, referred to in paragraph (1) was justified under the provisions of this Treaty and the Regulations, and, if it finds that the refusal or declaration was the result of an error or omission on the part of the receiving Office or that the finding was the result of an error or omission on the part of the International Bureau, it shall, as far as effects in the State of the designated Office are concerned, treat the international application as if such error or omission had not occurred.

(b)  Where the record copy has reached the International Bureau after the expiration of the time limit prescribed under Article 12(3) on account of any error or omission on the part of the applicant, the provisions of subparagraph (a) shall apply only under the circumstances referred to in Article 48(2).
