What mailing procedures can be used for ex parte reexamination correspondence?

The MPEP outlines two primary mailing procedures that can be used for most ex parte reexamination correspondence:

1. Certificate of Mailing and Transmission (37 CFR 1.8): This procedure can be used for filing any paper in an ex parte reexamination proceeding, except for the initial request for reexamination and a corrected/replacement request.
2. Priority Mail Express® Mailing (37 CFR 1.10): This procedure can be used to file any paper in an ex parte reexamination proceeding.

The MPEP states: “The certificate of mailing and transmission procedures (37 CFR 1.8) may be used to file any paper in an ex parte reexamination proceeding, except for a request for reexamination and a corrected/replacement request for reexamination.”

For more details on these procedures, refer to MPEP § 512 for certificate of mailing and MPEP § 513 for Priority Mail Express® mailing.
