What should I do if I mailed a reply to the USPTO but it wasn’t received?
If you mailed a reply to the USPTO with a certificate of mailing declaration but it wasn’t received, you may be able to petition to withdraw the holding of abandonment. The MPEP states:
“It may be that a reply to the Office action was mailed to the Office with a certificate of mailing declaration as a part thereof (MPEP § 512) but was not received in the Office. In this instance, adequate relief may be available by means of a petition to withdraw the holding of abandonment.”
To file this petition, you’ll need to provide evidence of the timely mailing, such as the certificate of mailing. It’s important to act quickly once you realize there’s an issue.
