Trademark Status Document Retrieval (TSDR) Access

Trademark Status Document Retrieval (TSDR) Access

Some customers attempting to access TSDR since Tuesday, May 31 may have encountered 404 errors, "Page not found" errors, or security certificate warnings.

If you encounter any of these issues, please use the secure version of the TSDR URL at https://tsdr.uspto.gov. If you do not use the "https" portion of the URL, some browsers may not correctly redirect to the secure site and will be unable to load the page. You may need to update any bookmarks that do not use the secure URL.

The USPTO is working to update our systems to resolve this issue automatically. If the above steps don't work for you, please contact the TEAS team at our email: TEAS@uspto.gov.
