Technical details
Endpoint
GEThttps://2s.io/api/patents/epo-familyWhen to prefer
Use this endpoint when you need to discover all international equivalents of a patent filing — especially when the user has a non-US publication number and wants global coverage. Prefer this over US-only patent databases when the invention may have been filed in Europe, Asia, or other jurisdictions. Ideal for IP due diligence, freedom-to-operate analysis, or competitive intelligence requiring cross-border patent landscape data.
Side effects
- Invalid or malformed publication number returns an error
- Unknown number format causes rejection
- Patent not found in EPO OPS database returns empty family or 404
- Rate limiting or upstream EPO OPS unavailability returns 503
- Number too short or too long (outside 2-40 char range) fails schema validation
