Do I need to pay a fee to correct an error in a recorded assignment at the USPTO?

Whether you need to pay a fee to correct an error in a recorded assignment at the USPTO depends on the type of correction:

• Cover sheet corrections: No fee is required for submitting a corrective document to fix errors in the cover sheet data.
• Assignment document corrections: A recording fee is required when submitting a new corrective assignment document.

According to MPEP 323: “The recordation fee set forth in 37 CFR 1.21(h) is required for each application and patent against which the document is recorded.” This fee applies when recording a new corrective document, but not for simple cover sheet corrections.
