How can I correct a returned assignment document at the USPTO?

If your assignment document is returned by the USPTO Assignment Division, you can correct it as follows:

• The returned document will be stamped with the original receipt date.
• It will come with a letter specifying a time period for correction and resubmission.
• If resubmitted within this period, the original receipt date may be considered the recording date.
• You can use the certification procedure (37 CFR 1.8) or “Priority Mail Express” (37 CFR 1.10) for resubmission.
• If not corrected within the specified period, the new submission date will be the recording date.

MPEP 317.02 states: “If the returned papers are corrected and resubmitted to the Office within the time specified in the letter, the Office will consider the original date of receipt of the papers as the date of recording of the document.”
