How do I change the correspondence address for a patent application?

To change the correspondence address for a patent application, you need to file a properly signed written request with the USPTO. According to MPEP 601.03:

“A written request may be signed by a practitioner of record, the applicant, an assignee of record, or a party who otherwise shows sufficient proprietary interest in the matter, in accordance with 37 CFR 1.33(b).”

The request should clearly state the new correspondence address and include the application number or patent number if already issued. For pending applications, you can use form PTO/AIA/122 or submit a signed letter.
