Verified steps
Obtain a USPTO Open Data Portal API key by signing in with a USPTO.gov account and linking an ID.me identity per the ODP getting-started process.
Query the Bulk Data product-data endpoint to list available trademark bulk products (e.g., daily or full trademark case-files/full-text XML datasets).
Call the Bulk Data download endpoint with the desired product/file identifier to retrieve the compressed XML dataset.
Parse the downloaded XML into your own store, mapping fields such as serial number, mark text, status, and owner of record.
Schedule periodic pulls of incremental (e.g., daily) files to keep your offline dataset current instead of re-downloading the full historical archive each time.
Known gotchas
Each API key is capped at 20 downloads of the same file per year — cache locally rather than re-fetching the same product repeatedly.
Bulk XML reflects a point-in-time snapshot; for a live, single-record status check, USPTO's TSDR API (not bulk data) is the appropriate tool.
USPTO decommissioned legacy developer.uspto.gov API endpoints in 2026 in favor of the Open Data Portal (data.uspto.gov) — verify you are using current ODP endpoints, not deprecated legacy-hub URLs.
