How this service works
Search US patent applications and grants via the USPTO Open Data Portal. Query: q (required, 2+ chars), yearFrom / yearTo (optional filing-year bounds), applicationType (optional: Utility|Design|Plant|Reissue), limit (1-100, default 10), offset (0-based, default 0). Returns { total, returned, offset, limit, hits[{ applicationNumber, title, applicationType, firstInventor, inventors[], applicants[], filingDate, effectiveFilingDate, status:{ code, description, updatedAt }, cpcSymbols[], uspcSymbol, url }] }. URLs link to USPTO Patent Center for the public file wrapper.
Output
Returns a JSON object with total matching patents, count returned, pagination info, and an array of patent hits each containing applicationNumber, title, applicationType, firstInventor, full inventors list, applicants, filingDate, effectiveFilingDate, status (code, description, updatedAt), CPC symbols, USPC symbol, and a direct link to the USPTO Patent Center file wrapper.
Example use cases
Example prompt
“Search USPTO patents for 'neural network image compression' filed between 2019 and 2023, Utility type only, and return the top 15 results.”
Technical details
Endpoint
GEThttps://2s.io/api/patents/searchWhen to prefer
Use this endpoint when you need to search US patent applications and grants with free-text keyword search across titles and abstracts, optionally scoped by filing year range or application type. Prefer this over manual USPTO searches or broader legal databases when you need structured patent metadata (inventors, applicants, CPC symbols, status) returned in a machine-readable format. Best for prior art research, patent landscape analysis, inventor lookups, and IP due diligence workflows.
Side effects
- Query shorter than 2 characters returns a validation error
- Invalid applicationType value (not Utility/Design/Plant/Reissue) returns an error
- limit outside 1-100 range returns a validation error
- Overly broad query may return generic or too-many results requiring further filtering
- USPTO Open Data Portal downtime may cause upstream failures
- No results found returns total=0 and empty hits array
