Can a mistake in assignee information on PTOL-85B be corrected via certificate of correction?
No, a mistake in assignee information on the Fee(s) Transmittal Form (PTOL-85B) cannot be corrected via a certificate of correction. The MPEP 1481.01 clearly states:
“Mistakenly adding assignee information on the form PTOL-85B is not a type of error correctable via certificate of correction.”
If you need to change or correct assignee information after the patent has been issued, you must follow the process outlined in 37 CFR 3.81(b), which includes submitting a request for a certificate of correction, paying the required fees, and stating that the assignment was submitted for recordation before the patent was issued.
