or\n(b) in a case where the United Kingdom has been elected in accordance with Chapter II of the Patent Co-operation Treaty—\n(i) before the expiry of nineteen months calculated from the declared priority date, the period of thirty months calculated from the declared priority date; or\n(ii) where there is no declared priority date and the United Kingdom has been so elected before the expiry of nineteen months calculated from the date of filing of the international application for a patent (UK), the period of thirty months calculated from the date of filing of that international application.\n(2) Where, in accordance with paragraph 1 of Schedule 2, the information specified in subparagraph (2)(a)(ii) of that paragraph is added to an international application for a patent (UK), rule 113(1) shall not apply in respect of that information; and where the translation of the information, the filing of which is required to satisfy the relevant conditions of section 89A(3), has not been filed at the Patent Office before the end of the relevant period referred to in paragraph (1) above,—\n(a) the comptroller shall give notice to the applicant at the address furnished by the applicant in accordance with rule 30 requiring the applicant to file the translation within the period of two months commencing on the day on which the notice is sent;

and\n(e) where a translation into English of a document or part of a document is required by the Act or these Rules to be filed—\n(i) before the end of the relevant period referred to in paragraph (1)(a) above, verification of the translation, as required by rule 113(1), may be given to the comptroller at any time before the end of the period of twenty-two months, or\n(ii) before the end of the relevant period referred to in paragraph (1)(b) above, verification of the translation, as required by rule 113(1), may be given to the comptroller at any time before the end of the period of thirty-two months,\nafter the declared priority date or, if there is no declared priority date, the date of filing of the international application for a patent (UK).\n(4) Where the relevant period referred to in paragraph (1) above has been extended under rule 100 or rule 110 so as to expire later than one month before the end of a period prescribed by paragraph (3) above or (7) below, paragraphs (3) above and (7) below shall have effect with the substitution for the period so prescribed of a period ending one month later than the relevant period referred to in paragraph (1) above as so extended.\n(5) For the purposes of section 89A(3) and (5), to the extent that the application and any amendment as published under the Patent Co-operation Treaty and any amendment annexed to the international preliminary examination report under Chapter II of the Treaty are not in English, a translation into English of the application as originally filed or, as the case may be, of the application as originally filed and of the amendment is necessary; however, the translation—\n(a) shall exclude the request and abstract unless—\n(i) the applicant expressly requests the comptroller to proceed earlier than the expiry of the period prescribed in paragraph (1) above; and\n(ii) a copy of the application published by the International Bureau has not yet been sent to the Patent Office in accordance with the Treaty; and\n(b) shall include any textual matter in the drawings in a form which complies with rule 49.5(d) of the Patent Co-operation Treaty.\n(6) The comptroller shall publish any translation supplied in accordance with section 89A(3) or (5) following the filing of Patents Form 43/77 and payment of the prescribed fee.\n(7) In the case of an international application for a patent (UK) in respect of which the conditions specified in section 89A(3)(a) are satisfied, the period prescribed—\n(a) for the purposes of sections 13(2), 15(5)(b) and 17(1),—\n(i) where subparagraph (a) of paragraph (1) above has effect, shall be the period which expires twenty-two months;

and\n(b) the comptroller determines that the application would not have been treated as withdrawn under the Act.\n(10) Where under section 89(3) an application is not to be treated as withdrawn and the applicant wishes to proceed—\n(a) the comptroller may amend any document received by the Patent Office from the receiving office or the International Bureau and alter any period or time which is specified in the Act or these Rules upon such terms (including payment of any appropriate prescribed fee) as he may direct; and\n(b) the fee prescribed under section 89A(3) shall not be payable.\n(11) Where the applicant satisfies the comptroller that,—\n(a) because of an error made by the receiving office, an international application for a patent (UK) has been accorded a date of filing which is not correct; or\n(b) the declaration made under Article 8(1) of the Patent Co-operation Treaty has been cancelled or corrected by the receiving office or the International Bureau because of an error made by the office or the Bureau,\nthe comptroller may amend any document received by the Patent Office from the receiving office or the International Bureau or alter any period or time which is specified in the Act or these Rules as if the error were an error on the part of the Patent Office.\n(12) Where—\n(a) an international application for a patent (UK) purports to designate the United Kingdom; and\n(b) the applicant alleges that he has been refused a filing date under the said Treaty on account of an error or omission in any institution having functions under the said Treaty,\nthe applicant may apply to the comptroller for it to be treated as an application under the Act by filing Patents Form 44/77, accompanied by a statement of the facts upon which he relies; and the comptroller may amend any document filed by the applicant and alter any period or time which is specified in the Act or these Rules upon such terms as he may direct.\n(13) In this rule “receiving office” has the same meaning as in the Patent Co-operation Treaty.",
