Full-text across 100+ offices, machine translations, and the \"Similar Documents\" panel does a decent semantic job. Known weaknesses: a lag on very recent publications, and you should verify legal status elsewhere. For a founder doing a first sanity check before spending money, this is the right first stop.\n\n**Espacenet (EPO)** - the one I'd use as the serious free follow-up.
