I built Sentin after realising I had no way of knowing if someone had filed a similar trademark to my own EU brand. EUIPO publishes 1,400+ new filings every week and you have 90 days to oppose. Nobody tells you. Sentin watches EUIPO every morning and emails you when something similar appears. It scores phonetic similarity, visual logo similarity, and class overlap. The alert includes the applicant details and your exact opposition deadline. Free plan for one trademark. No credit card.
