Our Analysis

The Verdict

The EUIPO API is a well-built, free API for EU trademark data — but it's EU-only, requires an approval process, uses RSQL query syntax, and offers no search intelligence. Signa includes all EUIPO data plus 200+ other offices, with instant access, simple query parameters, and built-in clearance analysis.

Best for

Signa

  • Projects needing EU data plus other jurisdictions
  • Teams that need instant API access without approval queues
  • Developers who prefer simple query parameters over RSQL
  • Products requiring trademark monitoring and clearance
  • Applications serving global (not just EU) markets

Best for

EUIPO API

  • EU-only trademark research projects
  • Teams with zero budget for API costs
  • Projects needing EU-specific media (sound marks, 3D models)
  • Official EUTM filing workflows via API
  • Academic research on EU trademark data

Recommendation

Use the EUIPO API if you only need EU data, have time for the approval process, and want zero cost. Use Signa if you need global coverage, instant access, or advanced search intelligence.
