Notes

Section titled “Notes”
  • Risk level is calculated using a multi-factor model: similarity score, class relatedness, conflict type, mark status, and fame factor.
  • The tool runs a truncated stem search when initial results are sparse — e.g., “GOOGEL” triggers a secondary search for “GOOG” to catch misspellings.
  • Famous marks (approximately 200 well-known brands) are checked locally to catch conflicts that API substring search would miss.
  • When goodsServicesTerms is provided, terms are validated against the EUIPO Harmonised Database and results appear in gsValidation.
  • The thresholdWarning field alerts when well-known marks were excluded by the similarity threshold.
