The process for revoking a power of attorney is outlined in MPEP 601.02 : “A power of attorney may be revoked at any stage in the proceedings of a case, and a power of attorney to a subsidiary attorney will not be revoked by appointment of a principal attorney.” To revoke a power of attorney: The applicant or assignee must submit a signed revocation document to the USPTO. The revocation should clearly state the intent to revoke the previous power of attorney. If appointing a new attorney or agent, a new power of attorney should be submitted along with the revocation. It’s important to note that revoking a power of attorney does not remove the attorney or agent from the record. To change the correspondence address, a separate request must be made.
