How does revocation of power of attorney affect pending applications?

When a power of attorney is revoked, it affects pending applications as follows:

• The revocation is effective upon receipt in the USPTO.
• It applies to all pending applications in which the attorney or agent was appointed, unless specifically limited.
• The Office will not communicate further with the revoked attorney/agent.
• The applicant must appoint a new representative or correspond directly with the Office.

As stated in MPEP 402.05: ‘A power of attorney may be revoked at any stage in the proceedings of a case.’ This means the revocation can occur at any point during the patent application process.
