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

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.
