Trademark knock-out check with live official verification: name in, conflict risk verdict out. Candidate conflicting marks are looked up in the USPTO TSDR system in real time and returned as verbatim official records (LIVE/DEAD status, owner, classes, dates) — research leads that could not be officially verified are labeled as such. US federal register; names the right register for non-US markets. Call before you commit to a name.
