What status information is available for international applications?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

For international applications and applications claiming the benefit of a published international application:

1. If the United States is indicated as a Designated State, status information is available for the national stage application and any application claiming benefit of the filing date of the published international application.
2. Only the serial number, filing date, application number, and whether the application is pending, abandoned, or patented may be provided.
3. A copy of the first page of the published international application or the corresponding page of the PCT Gazette must be supplied with the status request.

Status requests should be made in writing to the International Patent Legal Administration or directed to the PCT Help desk.
