USPTO trademark full-text search API: access card

What is the USPTO trademark search?

USPTO trademark full-text search API is the raw search interface behind the USPTO's public trademark database — every federal wordmark, owner, and registration record, published by US Patent and Trademark Office. Coverage: United States (federal); scale: the full federal trademark register — 649 records match the wordmark ACME alone, according to the catalog manifest. In our data — the Aidenix Atlas catalog of verified sources — this endpoint was last probed on 2026-07-24 and returned HTTP 200. What the card gives you:

The exact endpoint and a working request you can copy.
Authentication and rate limits: none — no API key required.
The query keys the source accepts and the fields it returns, verified against the live endpoint.

How do you query it?

A working query is one plain HTTP GET — in our data this exact request form was verified on 2026-07-24:

curl -X POST "https://tmsearch.uspto.gov/prod-v1-0-0/tmsearch" \
  -H "Content-Type: application/json" \
  -d '{"query":{"bool":{"should":[{"term":{"WM":{"value":"acme"}}}],"minimum_should_match":1}},"size":10,"_source":["wordmark","ownerName","alive","serialNumber","registrationNumber"]}'

The catalog recipe records these endpoints, all verified:

POST /prod-v1-0-0/tmsearch — the body is standard Elasticsearch DSL, response is an ES hits envelope with hits.totalValue.
term on field WM — exact wordmark match; match_phrase_prefix on WM — prefix search.
query_string across wordmark, ownerName, goodsAndServices — free-text search including owner names.
Registration status by serial number lives on a separate TSDR endpoint — a different manifest in our catalog.

What does it accept and return?

The interface contract is a short one: 5 query facets in, 7 field groups out. The table is generated from the catalog manifest, according to the probe of 2026-07-24 — every row below was checked against the live endpoint, not copied from vendor marketing:
