What should an applicant do if there are mistakes made by the USPTO in recording assignments?

The appropriate course of action when an applicant identifies mistakes made by the USPTO in recording assignments is to contact the Assignment Recordation Branch. This branch is specifically responsible for handling matters related to the recording of assignments and any corrections that may be needed. By reaching out to this branch, the applicant can formally request the necessary corrections or address any discrepancies in the recorded assignments, ensuring that the trademark ownership records are accurate and reflect the correct information.

Filing a new application would not be effective, as it does not resolve the issue with the previous assignment record and could unnecessarily complicate the situation. Submitting a complaint to federal court is not a practical approach for resolving administrative errors made by the USPTO, as it could involve lengthy and unnecessary legal proceedings. Ignoring the mistake could lead to confusion regarding ownership rights and could impede the applicant's ability to enforce their trademark rights, leading to potential legal complications in the future. Thus, contacting the Assignment Recordation Branch is the most direct and efficient way to correct the mistake.
