Sentin

What is Sentin?

Sentin is an automated EU trademark monitoring service by Sentin Tech. It scans the EUIPO database every morning and sends you an alert the same day a conflicting filing appears. Each alert clearly shows your 90-day opposition window, so you never miss a deadline. You set it up once, and Sentin handles the rest—no manual searches required.

Target users

Sentin is built for trademark holders—from sole traders and small business owners to multinational companies—who need to protect their EU trademark without hiring a law firm. It's especially useful for anyone who can't afford €1,500/year for manual monitoring or doesn't have the time to check the EUIPO database weekly.

Effect review

Sentin delivers exactly what it promises: automatic, daily trademark alerts that remove the risk of missing a 90-day opposition window. The AI-powered similarity scoring is a practical upgrade over manual searches that often miss phonetic and visual near-misses.
