Search US trademarks by wordmark text, owner name, or goods/services — the text search the USPTO offers no public API for. Pass `query` for full-text search (ranked best-match first), or `serial` / `registrationNumber` for an exact record. Filter with `field` (mark|owner|all), `status` (live=registered+pending only, default; all=includes dead/abandoned), and `intlClass` (Nice class, e.g. 9). Returns each mark's wordmark, serial, registration number, status (+ live flag), filing/registration/abandonment dates, owner, international classes, and goods/services. Corpus: USPTO full trademark register (public domain). Use law.trademark-status for live USPTO prosecution detail on a known serial.
