How to run a free trademark search (a knockout search)

A knockout search is a quick, do-it-yourself scan of the trademark register to "knock out" names that are obviously already taken. You're looking for identical or closely similar marks that are registered or pending for goods or services like yours. If your exact name is already registered for a competing product, it's far cheaper to learn that now — before you commission a logo, print packaging, or build a company around it.

The operative word is preliminary. A knockout search is the fastest, cheapest way to catch a dealbreaker, and it's worth running for any name you're serious about. What it is not is a green light: turning up nothing tells you only that no obvious conflict surfaced in one database, not that the name is yours to use. The next two sections cover how to run one well and what it structurally cannot see.

The US Patent and Trademark Office (USPTO) runs the official trademark database, and searching it is free. Go to tmsearch.uspto.gov — the Trademark Search system that replaced the older TESS tool in late 2023. No account, no fee. Here's a practical order to work through.

1. Search your exact name first. Start with a basic word-mark search for the precise spelling you plan to use. An identical mark that comes back registered and "Live" for a related product is your loudest warning sign.

2. Search how it sounds and what it means, not just how it's spelled. The USPTO compares marks by sound, appearance, and meaning — not exact spelling alone — so a search for only your exact spelling can miss close variants like "Kwik" for "Quick" or "Lyte" for "Light." Run phonetic equivalents, alternate spellings, common misspellings, and singular/plural forms too.

3. Pay attention to the class. Goods and services are sorted into 45 international classes under the Nice Classification (34 cover goods, 11 cover services). The same word can be registered by different owners in unrelated classes — "Dove" soap and "Dove" chocolate are registered by different companies for exactly this reason. A hit matters most when it sits in a class tied to what you actually sell.

4. Read the status and the description. Each record shows whether a mark is "Live" or "Dead" and whether it's a registration or a pending application. A "Dead" mark (abandoned or cancelled) is no longer an active federal registration — but that doesn't mean the name is free, because the former owner may still hold common-law rights from continued use. Open each relevant record and read its goods-and-services description to see how closely it overlaps with your business.

5. Don't skip pending applications. A pending application isn't a registration yet, but the USPTO can cite an earlier-filed one against a later application — so note live pending marks alongside finished registrations.

The federal register is only part of the picture. In the US, trademark rights can arise from simply using a name in commerce — these are called common-law rights — with no registration at all. A regional business that's used a name for years may hold enforceable rights in its area and never appear in the USPTO database. State trademark registrations, business and DBA filings, and product names living only in someone's marketing won't show up in a federal search either.

It also can't decide whether two marks legally conflict. That question — likelihood of confusion — is a multi-factor legal analysis: how similar the marks are, how related the goods and services are, how strong the existing mark is, and more. A knockout search surfaces candidates to look at; it doesn't render that verdict, and neither this page nor the USPTO's database can tell you a specific name is "clear." This isn't legal advice — an actual clearance opinion comes from a licensed trademark attorney who runs a comprehensive search and verifies the current record directly on USPTO.

So read a clean knockout search as "no obvious dealbreaker found," not "all clear." It's the right first filter — a floor, not a guarantee.

Here's the trap that catches founders: the .com is available, so the name feels safe. But domain availability and trademark status are completely separate systems. A registrar will happily sell you brandname.com even if "Brandname" is a registered trademark in your exact industry — it doesn't check, and owning the domain gives you no trademark rights. Plenty of names are wide open as a domain and already locked down as a trademark.

Social handles are the same story. You can settle on a name, buy the domain, and only then find the handle you need is gone on every platform your customers use — forcing an awkward "get_brandname" workaround that splinters the brand. The three things you need to line up — domain, handles, and trademark — live in three different places, and most founders check only one before spending money.

That's what snooze's free Name Safety Check at /name does in one pass: it checks whether the domain is available across .com, .io, .ai, .app, .dev, and .co, whether the matching social handles are free, and it runs a knockout search against public USPTO records — so you see all three signals side by side. When a specific mark looks worth a closer look, it points you to the official USPTO search to dig in. Like any knockout search, it's a preliminary signal, not a clearance.

A free knockout search is the right first move for everyone. If it comes back clean and the stakes are low, how far you take it from there is a question of your own risk tolerance. But the more you're about to put in — inventory, a national launch, outside funding — the less a clean knockout search covers on its own.

From there, two common paths. A comprehensive clearance search plus an opinion from a licensed trademark attorney is the thorough option: they search the common-law and state sources a knockout misses and assess conflict risk for your specific name and industry. If you decide to register, you can file yourself through the USPTO's Trademark Center (which replaced the older TEAS system in 2025), or pay a filing service such as LegalZoom or Trademark Engine to handle the paperwork on top of the government filing fee — which runs a few hundred dollars per class of goods or services. Forming an LLC, if you need one, is a separate step with its own state fee, typically somewhere from about $35 to $500 depending on the state.

Whatever you choose, start free: run the knockout search, check the domain and handles at the same time, and open your wallet for a name only once you know it isn't obviously spoken for.
