306.05(a) Location and Form of Certificate of Transmission
The certificate of transmission should be clearly labeled as such and should include a reference to the registration number or application serial number, the date of transmission, and the signature of the person attesting that the document is being transmitted on a certain date.
When possible, the certificate should appear on the document being transmitted, rather than on a separate sheet of paper. See 58 Fed. Reg. 54494 (Oct. 22, 1993).
If the certificate of fax transmission is presented on a separate paper, it must identify the document and the application or registration to which it relates.
