How do I revoke a power of attorney in a patent application?

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.

To revoke a power of attorney in a patent application:

• The applicant or assignee of the entire interest must submit a revocation signed by them.
• The revocation should be submitted to the USPTO in writing.
• It can be done by filing a new power of attorney (Form PTO/AIA/82) and checking the revocation box.
• Alternatively, you can submit a document specifically revoking the previous power of attorney.

As stated in the MPEP 402: ‘A power of attorney may be revoked at any stage in the proceedings of a case.’ It’s important to note that revoking a power of attorney does not remove attorneys from the list of patent practitioners associated with an application. To do that, you must file a separate request.
