Correspondence
92.1 Need for Letter and for Signature
(a) Any paper submitted by the applicant in the course of the international procedure provided for in the Treaty and these Regulations, other than the international application itself, shall, if not itself in the form of a letter, be accompanied by a letter identifying the international application to which it relates. The letter shall be signed by the applicant.
(b) If the requirements provided for in paragraph (a) are not complied with, the applicant shall be informed as to the non-compliance and invited to remedy the omission within a time limit fixed in the invitation. The time limit so fixed shall be reasonable in the circumstances; even where the time limit so fixed expires later than the time limit applying to the furnishing of the paper (or even if the latter time limit has already expired), it shall not be less than 10 days and not more than one month from the mailing of the invitation. If the omission is remedied within the time limit fixed in the invitation, the omission shall be disregarded; otherwise, the applicant shall be informed that the paper has been disregarded.
(c) Where non-compliance with the requirements provided for in paragraph (a) has been overlooked and the paper taken into account in the international procedure, the non-compliance shall be disregarded.
(a) Subject to Rules 55.1 and 55.3 and to paragraph (b) of this Rule, any letter or document submitted by the applicant to the International Searching Authority or the International Preliminary Examining Authority shall be in the same language as the international application to which it relates. However, where a translation of the international application has been transmitted under Rule 23.1(b) or furnished under Rule 55.2, the language of such translation shall be used.
(b) Any letter from the applicant to the International Searching Authority or the International Preliminary Examining Authority may be in a language other than that of the international application, provided the said Authority authorizes the use of such language.
(d) Any letter from the applicant to the International Bureau shall be in English, French or any other language of publication as may be permitted by the Administrative Instructions.
(e) Any letter or notification from the International Bureau to the applicant or to any national Office shall be in English or French.
92.3 Mailings by National Offices and Intergovernmental Organizations
Any document or letter emanating from or transmitted by a national Office or an intergovernmental organization and constituting an event from the date of which any time limit under the Treaty or these Regulations commences to run shall be sent by air mail, provided that surface mail may be used instead of air mail in cases where surface mail normally arrives at its destination within two days from mailing or where air mail service is not available.
92.4 Use of Telegraph, Teleprinter, Facsimile Machine, Etc.
(a) A document making up the international application, and any later document or correspondence relating thereto, may, notwithstanding the provisions of Rules 11.14 and 92.1(a), but subject to paragraph (h), be transmitted, to the extent feasible, by telegraph, teleprinter, facsimile machine or other like means of communication resulting in the filing of a printed or written document.
(b) A signature appearing on a document transmitted by facsimile machine shall be recognized for the purposes of the Treaty and these Regulations as a proper signature.
(c) Where the applicant has attempted to transmit a document by any of the means referred to in paragraph (a) but part or all of the received document is illegible or part of the document is not received, the document shall be treated as not having been received to the extent that the received document is illegible or that the attempted transmission failed. The national Office or intergovernmental organization shall promptly notify the applicant accordingly.
(d) Any national Office or intergovernmental organization may require that the original of any document transmitted by any of the means referred to in paragraph (a) and an accompanying letter identifying that earlier transmission be furnished within 14 days from the date of the transmission, provided that such requirement has been notified to the International Bureau and the International Bureau has published information thereon in the Gazette. The notification shall specify whether such requirement concerns all or only certain kinds of documents.
(e) Where the applicant fails to furnish the original of a document as required under paragraph (d), the national Office or intergovernmental organization concerned may, depending on the kind of document transmitted and having regard to Rules 11 and 26.3,
(i) waive the requirement under paragraph (d), or
(ii) invite the applicant to furnish, within a time limit which shall be reasonable under the circumstances and shall be fixed in the invitation, the original of the document transmitted,
provided that, where the document transmitted contains defects, or shows that the original contains defects, in respect of which the national Office or intergovernmental organization may issue an invitation to correct, that Office or organization may issue such an invitation in addition to, or instead of, proceeding under item (i) or (ii).
(f) Where the furnishing of the original of a document is not required under paragraph (d) but the national Office or intergovernmental organization considers it necessary to receive the original of the said document, it may issue an invitation as provided for under paragraph (e)(ii).
(g) If the applicant fails to comply with an invitation under paragraph (e)(ii) or (f):
(i) where the document concerned is the international application, the latter shall be considered withdrawn and the receiving Office shall so declare;
(ii) where the document concerned is a document subsequent to the international application, the document shall be considered as not having been submitted.
(h) No national Office or intergovernmental organization shall be obliged to receive any document submitted by a means referred to in paragraph (a) unless it has notified the International Bureau that it is prepared to receive such a document by that means and the International Bureau has published information thereon in the Gazette.
