Secrecy, National Security and Foreign Filing

Secrecy Order – prevents disclosure of the subject matter to anyone without the express written consent of the Commissioner. Remains in effect for one year and can be renewed.

National Security – must always be filed in home country first

Foreign Filing Licenses – there are two ways to get permission to file abroad: 1) file a petition for a foreign filing license; or 2) wait six months after filing an application. A retroactive license may be pursued if an unlicensed foreign filing has occurred through error and without deceptive intent. In order to obtain a retroactive license, the applicant must provide a list of countries the application has been filed. A foreign filing license may be revoked by the PTO, and foreign filings that occurred prior to the revocation need not be abandoned.
