1893.03(b) The Filing Date of a U.S. National Stage Application [R-5] - 1800 Patent Cooperation Treaty
1893.03(b) The Filing Date of a U.S. National Stage Application [R-5]
An international application designating the U.S. has two stages (international and national) with the filing date being the same in both stages. Often the date of entry into the national stage is confused with the filing date. It should be borne in mind that the filing date of the international stage application is also the filing date for the national stage application. Specifically, 35 U.S.C. 363 provides that
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) of this title.
Similarly, PCT Article 11(3) provides that
...an international filing date shall have the effect of a regular national application in each designated State as of the international filing date, which date shall be considered to be the actual filing date in each designated State.
37 CFR 1.496(a), first sentence, reads "International applications which have complied with the requirements of 35 U.S.C. 371(c) will be taken up for action based on the date on which such requirements were met." Thus, when the file wrapper label or PALM bib-data sheet and filing receipt are printed, the information is read from the PALM data base and the information printed in the filing date box is the date of receipt of 35 U.S.C. 371(c)(1), (c)(2) and (c)(4) requirements rather than the actual international filing date.
The NOTIFICATION OF ACCEPTANCE OF APPLICATION UNDER 35 U.S.C. 371 AND 37 CFR 1.495 (Form PCT/DO/EO/903), a copy of which is reproduced in MPEP § 1893.03(a), indicates the date of receipt of the 35 U.S.C. 371(c)(1), (c)(2), and (c)(4) requirements, and it also indicates the date of completion of all 35 U.S.C. 371 requirements, which is further explained below. >Filing receipts are mailed concurrently with the mailing of the Form PCT/DO/EO/903.<
The "Application Filing Date" field formerly displayed in PAIR was changed to "Filing or 371(c) Date" to clearly indicate that for international applications that enter the national stage under 35 U.S.C. 371, the information displayed in this field is the date of receipt of the 35 U.S.C. 371(c)(1), (c)(2) and (c)(4) requirements. Applicants are quite often confused as to the true filing date and will ask for corrected filing receipts thinking that the information thereon is wrong. This explanation should offer some clarity. For most legal purposes, the filing date is the PCT international filing date. Exceptions to this general rule include the following:
(A) Availability as a prior art reference under former 35 U.S.C. 102(e) (prior to the amendment by the American Inventors Protection Act of 1999 (AIPA) (Pub. L. 106-113, 113 Stat. 1501 (1999)). If a U.S. patent issued from an international application filed prior to November 29, 2000, the international application was not considered to have been filed in the United States for prior art purposes under 35 U.S.C. 102(e) and PCT Article 64(4)(a) until the date the application fulfilled the requirements of 35 U.S.C. 371(c) (1), (2), and (4).
(B) Availability as a prior art reference under 35 U.S.C. 102(e) as amended by the AIPA, and further amended by the Intellectual Property and High Technology Technical Amendments Act of 2002 (Pub. L. 107-273, 116 Stat. 1758 (2002)). If an international application was filed on or after November 29, 2000, but did not designate the U.S. or was not published in English under PCT Article 21(2), the international filing date is not treated as a U.S. filing date for prior art purposes under 35 U.S.C. 102(e). See MPEP § 706.02(a) and § 2136.03.
(C) Patent term adjustment under 35 U.S.C. 154(b)(1)(B) and 37 CFR 1.702(b) when the USPTO has failed to issue a patent within three years of the "actual filing date" of an application. In this situation, the "actual filing date" is the date the national stage commenced under 35 U.S.C. 371(b) or (f). See MPEP § 2730.
The "Date of Completion of all 35 U.S.C. 371 Requirements" included on the NOTIFICATION OF ACCEPTANCE OF APPLICATION UNDER 35 U.S.C. 371 AND 37 CFR 1.495 (Form PCT/DO/EO/903) is relevant for purposes of patent term adjustment under 35 U.S.C. 154(b)(1)(A)(i)(II) and 37 CFR 1.702(a)(1) when the USPTO has failed to mail at least one of a notification under 35 U.S.C. 132 or a notice of allowance under 35 U.S.C. 151 not later than fourteen months after the date on which the requirements under 35 U.S.C. 371 were fulfilled. This date is the latest of:
(A) the date of submission of the basic national fee;
(B) the date of submission or communication of the copy of the international application;
(C) the date of submission of the translation of the international application if the international application is not in the English language;
(D) the date of submission of an oath or declaration of the inventor in compliance with 35 U.S.C. 371 (c)(4) (see 37 CFR 1.497(c) for an explanation of when an oath or declaration will be accepted as complying with 35 U.S.C. 371(c)(4));
(E) the earlier of 30 months from the priority date or the date of request for early processing under 35 U.S.C. 371(f) if requested prior to 30 months from the priority date (Form PCT/DO/EO/903 will indicate the date early processing was requested);
(F) if a request for early processing has not been requested prior to 30 months from the priority date, the date of submission of any translation of the annexes to the international preliminary examination report if the translation of the annexes are filed within the time period set in a Notification of Missing Requirements (Form PCT/DO/EO/905) requiring either an English translation of the international application or an oath or declaration; and
(G) the date of submission of any surcharge for submitting the oath or declaration later than 30 months from the priority date.
