What is the date of receipt for assignment documents sent to the USPTO by fax?

The date of receipt for assignment documents sent to the USPTO by fax is determined by when the complete transmission is received. According to MPEP 302.09:

The date of receipt accorded to an assignment document sent to the Office by facsimile transmission is the date the complete transmission is received in the Office.

It’s important to note that the benefits of a certificate of transmission under 37 CFR 1.8 are available for fax submissions. This can provide additional protection in case of transmission issues.

For more information on date of receipt for electronic submissions, you can refer to MPEP § 502.01.
