USPTO Trademarks

US trademark registrations and applications with owner, class, and status data

Comprehensive US trademark data from the USPTO Trademark Status and Document Retrieval (TSDR) system and bulk XML files. Includes active and historical trademarks with mark text, owner/applicant details, Nice Classification codes, goods/services descriptions, filing and registration dates, current status, and attorney of record. Updated weekly from public domain USPTO data.

Coming Soon — Awaiting USPTO Data Migration

USPTO is migrating trademark data from the legacy TSDR system to their new Open Data Portal. The old bulk download and TSDR API endpoints have been decommissioned, and trademark data is not yet available on the new platform. We will begin collecting data automatically once USPTO completes the migration. Join our mailing list to be notified when this dataset goes live.
