27 – Petition for Retroactive Foreign Filing License
Deciding Office: The Office of Petitions
In general, these are the steps to follow for filing a Petition for Retroactive Foreign Filing License:
- A retroactive license may be sought if an unlicensed foreign filing has occurred through error and without deceptive intent. However, the requirements of 37 CFR 5.25 must be fulfilled in order for such a petition to be granted. Note that licenses under 37 CFR 5.25 are only made retroactive with respect to specific acts of foreign filing, and therefore the countries, the actual dates of filing and the establishing of the nature of the error must be provided for each act of proscribed foreign filing for which a retroactive license is sought. The showing of facts as to the nature of the error should include verified statements by all those persons responsible for or 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 verified statement must include the clause:
"I hereby declare that all statements made herein are of my own knowledge are true and that all statements made on information and belief are believed to be true; and further that these statements were made with the knowledge that willful false statements and the like so made are punishable by fine or imprisonment, or both, under Section 1001 of Title 18 of the United States Code and that such willful false statements may jeopardize the validity of the application or any patent issuing thereon."
- A petition for a Retroactive foreign filing license for material not related to any pending application (37 CFR 5.13) must also be accompanied by a translated copy of the material filed abroad without the benefit a foreign filing license.
