304.05 Certificate of Transmission by Electronic Mail

Under 37 C.F.R. 2.197, e-mail correspondence will be considered to be timely filed, even if received after the due date, if the correspondence is: (1) transmitted to the USPTO by e-mail on or before the due date; and (2) accompanied by a certificate attesting to the date of transmission. See TMEP §§306.05 et seq. regarding the certificate of transmission procedure under 37 C.F.R. 2.197.

If e-mail correspondence is timely filed with a certificate of transmission, but is not received by or is lost within the USPTO, the correspondence will be considered timely based on the date of transmission set forth on the certificate of transmission, if the party who transmitted the correspondence: (1) informs the USPTO in writing of the previous e-mail transmission of the correspondence within two months after becoming aware that the USPTO has no evidence of its receipt; (2) provides a copy of the previously transmitted correspondence, including the certificate of transmission; and (3) submits a statement attesting to the personal knowledge of transmission of the response. 37 C.F.R. 2.197(b). The statement attesting to the personal knowledge of transmission does not have to be verified. See TMEP §306.05(d) for additional information about correspondence that is transmitted with a certificate of transmission but not received by or lost within the USPTO.
