The Clearinghouse sends out an e-mail notification that provides you with an overview of the different statuses of your trademark records.
Your trademark record can be (1) "verified" which means that no further action will be requested from you (unless the Proof of Use is on "incorrect"), (2) "incorrect" which means that you will be able to correct the trademark record and (3) "invalid" which means that you have already used your chance to correct the trademark record and are no longer able to correct it without buying an additional correction (only available to prepaid accounts) or alternatively you can submit the trademark record again.
