TSDR Guide: The Record-Level Verification Layer for U.S. Trademarks
Trademark Status and Document Retrieval (TSDR) lets users check status and view/download documents for a trademark application or registration using the serial or registration number. For our data work, TSDR is an important record-level verification source.

Direct answer
What TSDR is
USPTO’s TSDR system provides status and document information for trademark applications and registrations. A user can enter a serial number or registration number, then review the status or documents associated with that record.
What TSDR is useful for
Document history
Review Office Actions, notices and other case documents.
Event timing
Use status/document dates to understand when lifecycle events occurred.
Maintenance information
For registrations, USPTO also provides maintenance-related information through TSDR.
Documents may not appear immediately
USPTO notes that newly filed documents may not always appear in TSDR on the same day. Time-sensitive workflows should therefore account for source timing rather than assuming every update is instantaneous.

TSDR verification workflow
Start with the identifier
Use the application serial number or registration number.
Check Status
Confirm the current status and key record fields.
Open Documents
Review the documents relevant to the event you are researching.
Record the verification point
For data work, retain the date/time and source context used to make the inclusion decision.
Additional context
TSDR is particularly important when a search result is not enough. The status view provides the current record-level state and related bibliographic information, while the Documents view exposes the actual correspondence and filings that explain many lifecycle events. For an Office Action cohort, for example, the status can identify the event but the document is where the refusal or requirement is actually described.
For scalable data work, TSDR should be treated as a verification source rather than a substitute for a data model. A professional workflow still needs to normalize the fields, distinguish applicant counsel from USPTO examining attorneys, preserve relevant dates, and record what was checked and when.
Common questions
Can I search TSDR by a trademark name alone?
TSDR is primarily record-oriented. USPTO instructs users to enter a serial number or registration number to check status and documents. Trademark Search is the better discovery layer when you do not already have the identifier.
Does TSDR update instantly?
USPTO notes that new documents may not always appear on the same day they are filed.
Why is TSDR useful for lead qualification?
It can provide record-level status and document evidence needed to verify the event or field that defines a cohort.
What TSDR contributes to a data workflow
| TSDR evidence | Data use |
|---|---|
| Record identity and current status | Confirms the application/registration context being evaluated. |
| Status/event chronology | Provides dates and sequence needed to understand the lifecycle. |
| Documents | Supports issue-level verification when the status label alone is insufficient. |
| Representation and correspondence information | Provides role-specific public fields that must be interpreted carefully. |
| Verification point | A professional workflow should record when the TSDR state was checked because it can change after extraction. |
