What documents are required when submitting a request for reexamination of a patent?

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.

When submitting a request for reexamination of a patent, the following documents are required:

• A copy of the printed patent in double column format, including the front page
• Any disclaimer, certificate of correction, or reexamination certificate issued for the patent
• Any relevant federal court decision, complaint in a pending civil action, or interference or derivation decision

As stated in MPEP 2219: “Requesters are required under 37 CFR 1.510(b)(4) to include a copy of the patent for which reexamination is requested, to serve as the specification for the reexamination proceeding.” This ensures that a complete history of the patent is available for consideration by the Office.
