MPEP SECTION SUMMARY

A license for foreign filing is not required to file an international application in the United States Receiving Office but may be required before the applicant or the U.S. Receiving Office can forward a copy of the international application to a foreign patent office, the International Bureau or other foreign authority.

A foreign filing license to permit transmittal to a foreign office or international authority is not required if the international application does not disclose subject matter in addition to that disclosed in a prior U.S. national application filed more than 6 months prior to the filing of the international application.
