It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice. To change the correspondence address for a patent under reexamination, the patent owner should submit a request to the USPTO. The MPEP 2222 provides specific instructions for such submissions: “Where a request for ex parte reexamination has been filed:” Mail Stop “Ex Parte Reexam” Attn: Central Reexamination Unit Commissioner for Patents P.O. Box 1450 Alexandria, VA 22313-1450 For inter partes reexamination requests, use “Mail Stop Inter Partes Reexam” instead. The MPEP also recommends: “It is strongly recommended that the Mail Stop information be placed in a prominent position on the first page of each paper being filed utilizing a sufficiently large font size that will direct attention to it.” To facilitate the process, patent owners can use Form PTO/AIA/81B for changing the correspondence address or power of attorney in reexamination proceedings.
