The Certificate of Mailing or Transmission can significantly affect the timeliness of USPTO submissions. According to MPEP 512 : “The date indicated on the Certificate of Mailing or Transmission will be used by the Office as the date of receipt of the paper or fee.” This means that even if there are delays in postal or electronic transmission, your submission will be considered timely if the certificate date is within the required deadline. However, it’s important to note that the actual mailing or transmission must occur on or before the certificate date. False certificates can lead to serious consequences, including invalidation of the submission and potential disciplinary action.
