Applicant May Rescind Nonpublication Request Anytime
Note:
An applicant can cancel a previously filed nonpublication request at any time before filing a foreign counterpart application.

An applicant may rescind a previously-filed nonpublication request at any time. See 35 U.S.C. 122(b)(2)(B)(ii). Form PTO/SB/36 (revision April 2001 or later) may be used to both rescind a nonpublication request and provide notice of foreign filing. The form is reproduced in MPEP § 1135. If applicant makes a nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) and then rescinds the nonpublication request before or on the date a foreign or international application (hereinafter “foreign filing” or “counterpart application”) directed to the invention disclosed in the U.S. application filed under 37 CFR 1.111(a)) in the USPTO is filed in a foreign country, or under a multilateral international agreement, that requires eighteen-month publication, the nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) will be treated as annulled and the application will be treated as if the nonpublication request was never made. Thus, if applicant filed a nonpublication request and then decided to file a counterpart application, applicant must file either: (1) a request to rescind the nonpublication request before filing the counterpart application; or (2) a notice of foreign filing no later than 45 days after the filing date of the counterpart application, to avoid abandonment of the application (35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c)).

Form PTO/SB/36 for Rescinding Nonpublication and Notifying Foreign Filing
Note:
The form must be used to rescind a nonpublication request and notify of foreign filing within 45 days after the counterpart application's filing date.

An applicant may rescind a previously-filed nonpublication request at any time. See 35 U.S.C. 122(b)(2)(B)(ii). Form PTO/SB/36 (revision April 2001 or later) may be used to both rescind a nonpublication request and provide notice of foreign filing. The form is reproduced in MPEP § 1135. If applicant makes a nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) and then rescinds the nonpublication request before or on the date a foreign or international application (hereinafter “foreign filing” or “counterpart application”) directed to the invention disclosed in the U.S. application filed under 37 CFR 1.111(a)) in the USPTO is filed in a foreign country, or under a multilateral international agreement, that requires eighteen-month publication, the nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) will be treated as annulled and the application will be treated as if the nonpublication request was never made. Thus, if applicant filed a nonpublication request and then decided to file a counterpart application, applicant must file either: (1) a request to rescind the nonpublication request before filing the counterpart application; or (2) a notice of foreign filing no later than 45 days after the filing date of the counterpart application, to avoid abandonment of the application (35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c)).

Notice of Foreign Filing Required When Rescinding Nonpublication Request
Note:
Applicants must provide a notice of foreign filing when rescinding a nonpublication request before filing a counterpart application in an eighteen-month publication country.

The mere filing of a request under 37 CFR 1.213(b) to rescind the previously filed nonpublication request does not comply with the notice of foreign filing requirement of 35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c) (for applicants who submitted a nonpublication request but before filing the request to rescind, also filed a counterpart application in another country, or under a multilateral international agreement, that requires eighteen-month publication of applications). Applicants are strongly encouraged to provide a notice of foreign filing whenever rescinding a nonpublication request in anticipation of filing a counterpart application in an eighteen-month publication country. Form PTO/SB/36 (revision April 2001 or later) provides both a rescission and notice of foreign filing. See MPEP § 1135. No benefit can be given to a certificate of mailing or transmission under 37 CFR 1.8 on a request to rescind a nonpublication request in determining whether there has been a rescission of a nonpublication request before or on the date a counterpart application is filed in an eighteen-month publication country. A rescission of a nonpublication request is not a paper required to be filed in the USPTO as provided for in 37 CFR 1.8(a). Thus, the provisions of 37 CFR 1.8 by their terms do not apply in this situation, and the USPTO must use the actual date of receipt in the USPTO as defined in 37 CFR 1.6 as the date of the rescission to determine whether the nonpublication request has been rescinded before or on the date of the filing of a counterpart application such that the application may be considered an application in which no nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) was made. Since a notice of foreign filing is required by the statute and 37 CFR 1.215(c), the benefit of a certificate of mailing or transmission under 37 CFR 1.8 will be given to a notice of foreign filing.

No Benefit for Certificate on Rescission Notice
Note:
A certificate of mailing cannot be used to prove the date of a request to rescind a nonpublication before filing in an eighteen-month publication country.

The mere filing of a request under 37 CFR 1.213(b) to rescind the previously filed nonpublication request does not comply with the notice of foreign filing requirement of 35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c) (for applicants who submitted a nonpublication request but before filing the request to rescind, also filed a counterpart application in another country, or under a multilateral international agreement, that requires eighteen-month publication of applications).

Rescission Date Not Filing Requirement
Note:
The actual date of receipt in the USPTO, not a filed paper, determines if a nonpublication request has been rescinded before or on the filing date of a counterpart application.

The mere filing of a request under 37 CFR 1.213(b) to rescind the previously filed nonpublication request does not comply with the notice of foreign filing requirement of 35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c) (for applicants who submitted a nonpublication request but before filing the request to rescind, also filed a counterpart application in another country, or under a multilateral international agreement, that requires eighteen-month publication of applications).

Certificate of Mailing Applies to Notice of Foreign Filing
Note:
A certificate of mailing under 37 CFR 1.8 can be used as evidence for a notice of foreign filing required by statute and 37 CFR 1.215(c).

The mere filing of a request under 37 CFR 1.213(b) to rescind the previously filed nonpublication request does not comply with the notice of foreign filing requirement of 35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c) (for applicants who submitted a nonpublication request but before filing the request to rescind, also filed a counterpart application in another country, or under a multilateral international agreement, that requires eighteen-month publication of applications).

Rescinding Nonpublication Before Foreign Filing
Note:
If an applicant rescinds a nonpublication request before filing a foreign application, the nonpublication is annulled and the application will be published.

An applicant may rescind a previously-filed nonpublication request at any time. See 35 U.S.C. 122(b)(2)(B)(ii). Form PTO/SB/36 (revision April 2001 or later) may be used to both rescind a nonpublication request and provide notice of foreign filing. The form is reproduced in MPEP § 1135. If applicant makes a nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) and then rescinds the nonpublication request before or on the date a foreign or international application (hereinafter “foreign filing” or “counterpart application”) directed to the invention disclosed in the U.S. application filed under 37 CFR 1.111(a)) in the USPTO is filed in a foreign country, or under a multilateral international agreement, that requires eighteen-month publication, the nonpublication request under 35 U.S.C. 122(b)(2)(B)(i) will be treated as annulled and the application will be treated as if the nonpublication request was never made. Thus, if applicant filed a nonpublication request and then decided to file a counterpart application, applicant must file either: (1) a request to rescind the nonpublication request before filing the counterpart application; or (2) a notice of foreign filing no later than 45 days after the filing date of the counterpart application, to avoid abandonment of the application (35 U.S.C. 122(b)(2)(B)(iii) and 37 CFR 1.213(c)).

Rescinding Nonpublication Request Without Making One
Note:
An applicant must not rescind a nonpublication request unless one was actually made, as it wastes Office resources and may delay prosecution.

An applicant should not rescind a nonpublication request or provide a notice of foreign filing unless a nonpublication request was actually made, because filing a rescission when one is not needed leads to a waste of Office resources and may delay prosecution in the application. Furthermore, filing a rescission of a nonpublication request where a nonpublication request was not originally made may result in a reduction to any patent term adjustment under 35 U.S.C. 154(b).
