Can I correct an error in a recorded USPTO assignment document without submitting a new assignment?

Yes, you can correct certain errors in a recorded USPTO assignment document without submitting a new assignment. The process depends on the type of error:

• For minor typographical errors, use a Corrective Cover Sheet.
• For more substantial errors, submit a Substitute Statement.

MPEP 323 states: “The ‘corrective document’ or ‘substitute statement’ will not be recorded as a new assignment.” Instead, it will be recorded to correct the original assignment document, maintaining the original recordation date.
