Trademark clearance · five axes, one signed verdict

Trademark clearance isn’t finished until you know what to do about it.

One axis decides — Trademark. Four more tell you what to handle. Each carries a plain verdict and its evidence. Below is a real signed verdict from the live engine.

The exact name appears only in unrelated places — a declined surname, word-salad captions, a tyre-shop post — never a company or product. Nobody trades as Pentonym.

What clearance checks

A name can be clean on the register and still unsafe

Short answer

Trademark clearance is checking whether a name is legally safe to adopt in the United States — screening registered and common-law US marks for a likelihood of confusion in your goods or services. A conflicting senior mark can bar the name; a taken domain or handle cannot.

Clearance is not one search. A name can be clean on the federal register and still unsafe — because someone already uses it in commerce without registering, or because it collides in a class that matters to you. A real clearance looks at five things, and treats them differently.

  • US trademarks — federal registrations, pending applications, and unregistered (common-law) use, judged for a likelihood of confusion within your Nice class. The only check that can bar a name.
  • Domains, handles, and web use — whether the name is practically available to operate under. These inform the decision; they never bar it.
  • Cultural flags — whether the name reads as an offensive term in the markets you'll sell in.
What bars a name

What can bar a name — and what can’t

This distinction is the whole point. Most tools blur it and call a name “unavailable” because a .com is gone. That is not how trademark risk works.

Can bar the name

  • A senior US registration confusingly similar in your class
  • A pending application with priority
  • Established common-law use in your trading area

Never bars — you decide

  • The .com (or any TLD) is taken
  • A social handle is taken
  • A same-name business in an unrelated class

A taken domain is a workaround, not a verdict. Pentonym hands you every material signal and reserves the single red verdict for a genuine trademark conflict.

Cost

What clearance — and filing — cost

Clearance with Pentonym is free. If the name clears and you decide to file, the US government fee is charged per class:

ItemWhat it is2026 fee
USPTO base filingper class, electronic$350
Two classese.g. software + SaaS$700
Statement of useintent-to-use basis$150

Full breakdown in the trademark cost calculator. The point of clearing first: a $350 filing on a name that was never clearable is $350 you don’t get back.

FAQ

Common questions

Is a trademark clearance search the same as a USPTO search?

No. A USPTO/TESS search only shows the federal register. Clearance also weighs common-law (unregistered) use and applies a likelihood-of-confusion analysis within your class — which is what actually decides conflicts.

Does Pentonym cover trademarks outside the United States?

It covers the US and the EU. The US screen is a full likelihood-of-confusion analysis over a 14.1M-mark index; the EU screen is a live EUIPO exact-wordmark knockout. It does not search other national registers, so it is US & EU, not worldwide.

Is this legal advice?

No. Pentonym is a screening signal to inform your decision and your conversation with counsel — not a legal opinion.

What do I actually get back?

A three-state verdict — PROCEED, DO_NOT_PROCEED, or CANNOT_DETERMINE — never a score. It is an Ed25519-signed receipt you can verify yourself against our published key.
