How can a patent owner change the correspondence address after a patent issues?

According to MPEP 2622, a patent owner can change the correspondence address after a patent issues. The process depends on whether a reexamination proceeding is pending:

1. If a reexamination proceeding is pending, address the request to:

Mail Stop “Inter Partes Reexam”
Attn: Central Reexamination Unit
Commissioner for Patents
P.O. Box 1450
Alexandria, VA 22313-1450

2. If no reexamination is pending and the patent is in storage, address the request to:

Mail Stop Document Services
Director of the U.S. Patent and Trademark Office
P.O. Box 1450
Alexandria, VA 22313-1450

The MPEP strongly recommends placing the Mail Stop information prominently on the first page of the submission. If the patent owner wants a different attorney or agent to receive correspondence, a new power of attorney must be filed.

For specific forms, the MPEP mentions Form PTO/AIA/81B for patent owners to change power of attorney or correspondence address in reexamination or supplemental examination proceedings.
