How is the reexamination certificate distributed?

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.

The reexamination certificate is distributed in several ways:

• An e-copy is associated with the e-copy of the patent in the search files.
• It is included in any patent copies prepared by the USPTO after the certificate’s issuance.
• Copies are forwarded to all depository libraries.
• Copies are sent to foreign offices with exchange agreements with the USPTO.

As stated in MPEP 2292: “An e-copy of the reexamination certificate will be associated with the e-copy of the patent in the search files. A copy of the certificate will also be made a part of any patent copies prepared by the Office subsequent to the issuance of the certificate.”
