An international application designating the United States shall have the effect, from its international filing date under article 11 of the treaty, of a national application for patent regularly filed in the Patent and Trademark Office.
[Editor Note: Applicable to applications not subject to the first inventor to file provisions of the AIA (see 35 U.S.C. 100 (note)). See 35 U.S.C. 363 immediately above for the law otherwise applicable.]
An international application designating the United States shall have the effect, from its international filing date under article 11 of the treaty, of a national application for patent regularly filed in the Patent and Trademark Office except as otherwise provided in section 102(e).
[Editor Note: See pre-AIA 37 CFR 1.431 in Appendix R for para. (b)(3)(iii) applicable to applications filed before September 16, 2012]
An international filing date is accorded to the earliest date on which the requirements under PCT Article 11(1) were satisfied. If the requirements under PCT Article 11(1) are not satisfied as of the date of initial receipt of the international application papers, the receiving Office will invite applicant to correct the deficiency within a set time limit. See PCT Article 11(2) and PCT Rule 20.3. In such case, the international filing date will be the date on which a timely filed correction is received by the receiving Office. If the defect under PCT Article 11(1) is that the purported international application fails to contain a portion which on its face appears to be a description or claims, and if the application, on its initial receipt date, contained a priority claim and a proper incorporation by reference statement, the initial receipt date may be retained as the international filing date if the submitted correction was completely contained in the earlier application. See PCT Rules 4.18 and 20.6. If the defect under PCT Article 11(1) is not timely corrected, the receiving Office will promptly notify the applicant that the application is not and will not be treated as an international application. See PCT Rule 20.4. Where all the sheets pertaining to the same international application are not received on the same day by the receiving Office, in most instances, the date of receipt of the application will be amended to reflect the date on which the last missing sheets were received. As an amended date of receipt may cause the priority claim to be forfeited, applicants should assure that all sheets of the application are deposited with the receiving Office on the same day. If the application, on its initial receipt date, contained a priority claim and a proper incorporation by reference statement, the initial receipt date may be retained as the international filing date if the submitted correction was completely contained in the earlier application. Again see PCT Rules 4.18 and 20.6.
An all too common occurrence is that applicants will file an international application in the U.S. Receiving Office and no applicant has a U.S. residence or nationality. Applicants are cautioned to be sure that at least one applicant is a resident or national of the U.S. before filing in the U.S. Receiving Office. Where no applicant indicated on the request papers is a resident or national of the United States, the USPTO is not a competent receiving Office for the international application under PCT Rule 19.1(a). Nonetheless, the date the international application was filed in the USPTO will not be lost as a filing date for the international application if at least one applicant is a resident or national of any PCT Contracting State. Under PCT Rule 19.4, the USPTO will receive the application on behalf of the International Bureau as receiving Office (PCT Rule 19.4(a)) and, upon payment of a fee equal to the transmittal fee, the USPTO will promptly transmit the international application to the International Bureau under PCT Rule 19.4(b). However, if all of the applicants are indicated to be both residents and nationals of non-PCT Contracting States, PCT Rule 19.4 does not apply, and the application is denied an international filing date.
The USPTO is also not competent to receive international applications that are not in the English language and, upon payment of a fee equal to the transmittal fee, the USPTO will forward such applications to the International Bureau under PCT Rule 19.4 provided they are in a language accepted by the International Bureau as receiving Office.
A discussion of PCT Rule 19.4 is also included in MPEP § 1805.
