A straight answer, with the evidence

We compare your name with live and past trademarks, keep only close matches, and tell you what they mean.

  • Looks available

    No live trademark is identical, near identical or similar to your name.

  • Similar marks found

    Nothing matches exactly, but close spellings or sound-alikes are live.

  • Likely taken

    A live trademark matches your name. You see who owns it and where.

FAQ

Frequently asked questions

How do I check if a name is already trademarked?

Enter the name above. The checker compares it with live, pending and past trademarks in the registers Signa indexes and tells you whether a live mark already exists and who owns it.

Does a match mean I can't use the name?

Not always. Trademark rights cover specific goods and services (Nice classes) in specific countries. A match is a reason to look closer, so screen the name properly or ask an attorney before you adopt it.

What does it mean if no trademarks are found?

It is a good first sign, not a guarantee. Unregistered rights and very recent filings may not show up yet. Confirm with a full screening before you file.

Is the trademark checker free?

Yes, and you do not need an account. The Signa API runs the same search from your own code, plus monitoring of new filings.
