(a) FILING IN FOREIGN COUNTRY.—Except when authorized by a license obtained from the Commissioner of Patents a person shall not file or cause or authorize to be filed in any foreign country prior to six months after filing in the United States an application for patent or for the registration of a utility model, industrial design, or model in respect of an invention made in this country. A license shall not be granted with respect to an invention subject to an order issued by the Commissioner of Patents pursuant to section 181 without the concurrence of the head of the departments and the chief officers of the agencies who caused the order to be issued. The license may be granted retroactively where an application has been filed abroad through error and the application does not disclose an invention within the scope of section 181.
(b) APPLICATION.—The term "application" when used in this chapter includes applications and any modifications, amendments, or supplements thereto, or divisions thereof.
(c) SUBSEQUENT MODIFICATIONS, AMENDMENTS, AND SUPPLEMENTS.—The scope of a license shall permit subsequent modifications, amendments, and supplements containing additional subject matter if the application upon which the request for the license is based is not, or was not, required to be made available for inspection under section 181 and if such modifications, amendments, and supplements do not change the general nature of the invention in a manner which would require such application to be made available for inspection under such section 181. In any case in which a license is not, or was not, required in order to file an application in any foreign country, such subsequent modifications, amendments, and supplements may be made, without a license, to the application filed in the foreign country if the United States application was not required to be made available for inspection under section 181 and if such modifications, amendments, and supplements do not, or did not, change the general nature of the invention in a manner which would require the United States application to have been made available for inspection under such section 181.

(a) Filing of an application for patent for inventions made in the United States will be considered to include a petition for license under 35 U.S.C. 184 for the subject matter of the application. The filing receipt will indicate if a license is granted. If the initial automatic petition is not granted, a subsequent petition may be filed under paragraph (b) of this section.
(b) A petition for license must include the fee set forth in §1.17(g)of this chapter, the petitioner’s address, and full instructions for delivery of the requested license when it is to be delivered to other than the petitioner. The petition should be presented in letter form.

(a) A petition for retroactive license under 35 U.S.C. 184 shall be presented in accordance with § 5.13 or § 5.14(a), and shall include:

(1) A listing of each of the foreign countries in which the unlicensed patent application material was filed,
(2) The dates on which the material was filed in each country,
(3) A verified statement (oath or declaration) containing:

(i) An averment that the subject matter in question was not under a secrecy order at the time it was filed aboard [sic], and that it is not currently under a secrecy order,
(ii) A showing that the license has been diligently sought after discovery of the proscribed foreign filing, and
(iii) An explanation of why the material was filed abroad through error without the required license under § 5.11 first having been obtained, and

(4) The required fee (§ 1.17(g) of this chapter).

(b) The explanation in paragraph (a) of this section must include a showing of facts rather than a mere allegation of action through error. The showing of facts as to the nature of the error should include statements by those persons having personal knowledge of the acts regarding filing in a foreign country and should be accompanied by copies of any necessary supporting documents such as letters of transmittal or instructions for filing. The acts which are alleged to constitute error should cover the period leading up to and including each of the proscribed foreign filings.
(c) If a petition for a retroactive license is denied, a time period of not less than thirty days shall be set, during which the petition may be renewed. Failure to renew the petition within the set time period will result in a final denial of the petition. A final denial of a petition stands unless a petition is filed under § 1.181 within two months of the date of the denial. If the petition for a retroactive license is denied with respect to the invention of a pending application and no petition under § 1.181 has been filed, a final rejection of the application under 35 U.S.C. 185 will be made.
