How this service works
Search worldwide patent publications via the European Patent Office's Open Patent Services (OPS). Pass a CQL query (e.g. ti=quantum computing, in=tesla, pa=siemens, cpc=H01M, pn=EP1000000) and get matching publications with country, document number, kind code, and a combined publication number, plus the total result count. Covers EP + 100+ patent authorities worldwide — net-new vs our US-only patents.search.
Output
A list of matching patent publications each containing country code, document number, kind code, and a combined publication number, plus the total count of matching results across EP and 100+ worldwide patent authorities.
Example use cases
Example prompt
“Search worldwide patents for quantum computing inventions by Tesla — use the CQL query 'ti=quantum computing and pa=tesla' and return up to 20 matching publications with their country, document number, and kind code.”

- Limit parameter outside 1-100 range returns validation error
- No results found for highly specific queries
- EPO OPS upstream service unavailable causing timeout or 5xx error
