REGISTERED - BACKFILE
Status code: 624

The "backfile" refers to trademark applications and registrations that existed before we went to a digital system. Many of these applications or registrations are not searchable except by the serial number, and have few materials available through TSDR. This status code will rarely be triggered for your marks, as it only applies to registered trademarks that currently exist in the backfile.
