MPEP 500 – Receipt and Handling of Mail and Papers (2)

If correspondence with a Certificate of Mailing or Transmission is not received by the USPTO after a reasonable amount of time, you can take steps to notify the Office and provide evidence of the previous timely filing. According to 37 CFR 1.8(b):

In the event that correspondence is considered timely filed by being mailed or transmitted in accordance with paragraph (a) of this section, but not received in the U.S. Patent and Trademark Office after a reasonable amount of time has elapsed from the time of mailing or transmitting of the correspondence […] the correspondence will be considered timely if the party who forwarded such correspondence: (1) Informs the Office of the previous mailing or transmission of the correspondence promptly after becoming aware that the Office has no evidence of receipt of the correspondence; (2) Supplies an additional copy of the previously mailed or transmitted correspondence and certificate; and (3) Includes a statement that attests on a personal knowledge basis or to the satisfaction of the Director to the previous timely mailing, transmission or submission.

It’s recommended to check the private Patent Application Information Retrieval (PAIR) System first to see if the correspondence has been entered into the application file before notifying the Office.

If the Certificate of Mailing or Transmission is omitted from a paper, the USPTO will treat the paper as though it was not received. According to MPEP 512:

“If the certification of mailing or transmission is omitted and the paper is later received by the U.S. Patent and Trademark Office, the paper will be considered as having been filed as of the date of receipt in the Office.”

This means that without the certificate, the paper’s filing date will be the actual date it’s received by the USPTO, which could potentially be later than intended and may have significant consequences for patent applications or other time-sensitive submissions.
