108.01    Internet Information

The Trademark Status and Document Retrieval (TSDR) database on the USPTO website at provides detailed information about the status and prosecution history of trademark applications and registrations.  The TSDR database is available 24 hours a day, 7 days a week.

The TSDR database is normally updated shortly after our internal databases are updated. However, the TSDR database may not reflect changes in ownership that have been recorded in the Assignment Recordation Branch.  There are circumstances in which the Trademark database will be updated automatically upon the recordation of a change of ownership. See TMEP §504.  In all other cases, the new owner must separately notify the Trademark Operation in writing of the recordation of a document, and request that the Trademark database be updated manually. See TMEP §§503.01(a), 504.01, and 505-505.02.

Information about documents recorded with the Assignment Recordation Branch can be viewed though Assignments on the Web (AOTW) at
