How does changing the correspondence address affect power of attorney in patent cases?

Changing the correspondence address in a patent case does not automatically affect the power of attorney. Key points to note:

• A change of correspondence address does not revoke an existing power of attorney
• The attorney of record can change the correspondence address
• Applicants can file a separate request to change the address without affecting the power of attorney

MPEP 2560 states, “A request for a change of correspondence address does not revoke a power of attorney.” To revoke a power of attorney, a separate revocation must be filed with the USPTO.
