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.
