Official tools for search and status

Find the right identifier
Search the official trademark database and confirm the mark you are reviewing. Keep its application serial number or registration number for the next step.
Read status in TSDR
Enter that number in TSDR and open Status. Compare the mark, owner, goods and services, and record history rather than relying on a name match alone.
Check the documents
Use Documents to review the available filings and correspondence. Newly filed documents may take time to appear; refer to the official status guide for details.
