How this service works
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.
Output
A ranked list of trademark records, each containing: wordmark text, USPTO serial number, registration number, current status (registered/pending/abandoned/etc.) with a live boolean flag, filing date, registration date and/or abandonment date, owner name, Nice international class(es), and goods/services description. Results are ranked by relevance for full-text queries, or return a single exact record for serial/registration number lookups.
Example use cases
Example prompt
“Can you search the USPTO trademark register for live trademarks with the wordmark 'Sunrise' in Nice class 25 (clothing), and show me the owner, status, filing date, and goods/services for each result?”
Technical details
Endpoint
GEThttps://2s.io/api/law/trademark-searchWhen to prefer
Use this endpoint when you need to search the USPTO trademark register by text (wordmark, owner, or goods/services) — a capability the USPTO itself offers no public API for. Prefer this over law.trademark-status when you don't have a known serial number and need discovery/search. If you already have a serial number and need detailed prosecution history, use the sibling law.trademark-status endpoint instead.
Side effects
- No results found for query — trademark not in USPTO register or search terms too specific
- Invalid serial/registration number format — returns error or empty result
- Invalid intlClass value — filter silently ignored or returns error
- Query too vague — returns many irrelevant results; refine with field or intlClass filters
- Rate limit or payment failure — x402 payment not processed, returns 402 status
