Can I use a certificate of mailing for all USPTO correspondence?

While the certificate of mailing or transmission is a useful tool, it cannot be used for all types of USPTO correspondence. The MPEP 502 provides specific exceptions:

“The certification procedure under 37 CFR 1.8 is not available for: (A) Applications for patent under 35 U.S.C. 111(a), including reissue applications; (B) International applications for patent; (C) International design applications; (D) Requests for reexamination under 35 U.S.C. 302…”

This list continues with several other exceptions. It’s crucial to note that:

• New patent applications cannot use the certificate of mailing.
• International applications are excluded from this procedure.
• Certain time-sensitive documents require different filing methods.

For these excluded items, consider using Priority Mail Express® or electronic filing to ensure timely receipt by the USPTO. Always check the current regulations or consult with a patent professional to determine the appropriate filing method for your specific correspondence.
