Verdicts

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.

How it works

From a name to an answer

A quick first check you can run before you spend money on a logo, a domain or a filing.

  1. 01

    Enter your brand name

    Type the business or brand name you want to use. Narrow it to one jurisdiction or Nice class if you like.

  2. 02

    Get a verdict

    We search exact, near-exact, spelling and sound-alike matches and tell you if the name looks available, similar or taken.

  3. 03

    Check the evidence

    Every close match shows its status, office, classes and owner, linked to the owner's company page.

  4. 04

    Screen it properly

    A quick check is not legal clearance. Run a full screening through the Signa API or with an attorney before you file.

FAQ

Frequently asked questions

Is this a full trademark clearance search?

No. It is a fast first check of your name against the trademark registers Signa indexes. Full clearance also covers every relevant class, unregistered rights and legal judgement, so confirm with a full screening or an attorney before you file.

How is the verdict worked out?

We keep only close matches: identical, near-identical and similar names. If a live mark is identical or near-identical, the name is likely taken. If only similar marks are live, we flag them. If nothing close is live, the name looks available.

Which trademark offices are covered?

Every register Signa indexes, including the USPTO, EUIPO, WIPO and UKIPO, plus a growing set of national registers. You can narrow the check to one jurisdiction or Nice class.

Is the brand name availability checker free?

Yes, and you do not need an account. For searches from your own code, monitoring and bulk checks, use the Signa API.
