If you are registered with the Clearinghouse as a trademark holder and your mark record has been verified you need to contact the support desk in order to edit the address. Once a ticket has been created, one of agents will then put the mark record on incorrect so that you can edit the mark record. Please note that this means that we will need to re-verify the information again and your SMD file when no longer be available. A new SMD file will provided to you upon re-verification.
