Are there additional charges for correcting errors in my trademark record?
You will have the possibility to correct errors free of charge one time. You will be notified by the verification agents of the Clearinghouse should the information you submitted be incorrect. You can provide a correction within a time limit of thirty-five (35) calendar days. Only if the information is still incorrect after this first correction, or if you have failed to correct the information within thirty-five (35) calendar days, your trademark record will be invalidated.
