PCT Rule 92
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.

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.
- (c) [Deleted]
- (d) Any letter from the applicant to the International Bureau shall be in English or French.

PCT Administrative Instructions Section 105
Identification of International Application With Two or More Applicants
Where any international application indicates two or more applicants, it shall be sufficient, for the purpose of identifying that application, to indicate, in any Form or correspondence relating to such application, the name of the applicant first named in the request. The provisions of the first sentence of this Section do not apply to the demand.
I. NOTIFICATION UNDER PCT RULE 92.1(b) OF DEFECTS WITH REGARD TO CORRESPONDENCE
If the Office finds that papers, other than the international application itself, are not accompanied by a letter identifying the international application to which they relate, or are accompanied by an unsigned letter, or are furnished in the form of an unsigned letter, it notifies the applicant and invites him or her to remedy the omission. The Office disregards the said papers or letter if the omission is not remedied within the time limit fixed in the invitation (PCT Rule 92.1(b)). If the omission has been overlooked and the paper taken into account, the omission is disregarded.
II. CORRESPONDENCE ADDRESS
Where there is a sole applicant without an agent in an international application, correspondence will be sent to the applicant at his or her indicated address; or, if he or she has appointed one or more agents, to that agent or the first-mentioned of those agents; or, if he or she has not appointed an agent but has indicated a special address for notifications, at that special address.
Where there are two or more applicants who have appointed one or more common agents, correspondence will be addressed to that agent or the first-mentioned of those agents. Where no common agent has been appointed, correspondence will be addressed to the common representative (either the appointed common representative or the applicant who is considered to be the common representative (PCT Rule 90.2) at the indicated address; or, if the common representative has appointed one or more agents, to that agent or the first-mentioned of those agents; or, if the common representative has not appointed an agent but has indicated a special address for notifications, at that address.
III. FILING OF CORRESPONDENCE BY MAIL
The Priority Mail Express® procedure set forth at 37 CFR 1.10 applies to papers filed with the U.S. Patent and Trademark Office (USPTO) in international applications. Accordingly, papers filed with the USPTO in international applications will be accorded by the USPTO the “date accepted” indicated on the Priority Mail Express® mailing label as the date of filing in the USPTO if the provisions of 37 CFR 1.10 are complied with. See MPEP § 513.
If there is a question regarding the date of deposit, the Priority Mail Express® provisions of 37 CFR 1.10(c) – (e) require, in addition to using the Priority Mail Express® Post Office to Addressee service, an indication of the Priority Mail Express® mailing label number on each paper or fee. In situations wherein the correspondence includes several papers directed to the same application (for example, Request, description, claims, abstract, drawings, and other papers) the correspondence may be submitted with a cover or transmittal letter, which should itemize the papers. The cover or transmittal letter must have the Priority Mail Express® mailing label number thereon.
The certificate of mailing by first class mail procedure set forth at 37 CFR 1.8 differs from the 37 CFR 1.10 Priority Mail Express® procedure. See 37 CFR 1.8(a)(2)(i)(D) and (E). It is important to understand that the 37 CFR 1.8 certificate of mailing procedure CANNOT be used for filing any papers during the international stage if the date of deposit is desired. If the 37 CFR 1.8 certificate of mailing procedure is used, the paper and/or fee will be accorded the date of receipt in the USPTO unless the receipt date falls on a Saturday, Sunday, or federal holiday in which case the date of receipt will be the next succeeding day which is not a Saturday, Sunday, or federal holiday (37 CFR 1.6(a)(1)). Accordingly, the certificate of mailing procedures of 37 CFR 1.8 are not available to have a submission during the international stage considered as timely filed if the submission is not physically received at the USPTO on or before the due date.
