How to Check if a Business Name Is Trademarked

No single database answers “is this name trademarked.” A proper clearance search is four searches stacked on each other: the federal register at the USPTO, the state registers where you actually trade, a common-law sweep for businesses using the name without ever registering it, and a domain and handle check that surfaces users nobody indexed. Run them in that order, because each step is cheaper than the next, and most doomed names die in the first twenty minutes.

Here is the sequence, plus the mistake that makes each step useless.

Start with the exact match on the USPTO

Open the USPTO’s Trademark Search tool, the free system that replaced TESS in late 2023, and type the name exactly as you plan to use it. If a live federal registration already covers your exact name in your line of business, you are finished searching and you need a different name.

Two corrections before you read results. First, a hit only counts if the record is live. Applications get abandoned and registrations lapse, and dead records sit in the database forever. Second, the register is organized by class: trademark rights attach to a name plus the goods or services it is used on. The same word registered for hydraulic pumps rarely blocks a bakery.

Search the way an examiner does, not the way a founder does

An examining attorney is not hunting for identical strings. The legal test is likelihood of confusion, and it weighs sound, appearance, meaning and overall commercial impression together. An exact-match search misses nearly all of that, so widen it on purpose:

• Phonetic near-matches. Kwik and Quick, Fotos and Photos, Zeta and Zita. If it sounds the same spoken aloud, treat it as a hit.
• Spelling variants. Doubled letters, dropped vowels, plurals, hyphens, and the “ly” or “ify” tails founders bolt on when the first choice is gone.
• Synonyms and translations. The same idea in different words can still create confusion, and Spanish and French equivalents come up often in US filings.
• The distinctive half alone. In “Northgate Coffee Roasters,” the trademark weight sits on Northgate. Search that by itself. The descriptive words carry almost none.

Run each variant as its own search. Two narrow searches beat one clever one.

Read the record, not the hit count

Open every live hit that is even close and check four fields: status, owner, goods and services, and date of first use. Status separates registered from pending from dead. The goods and services text shows how wide the owner’s claim really is, and it varies enormously, from one narrow line to paragraphs spanning six classes. Owner tells you whether you are looking at a dormant sole trader or a company with a litigation habit.

First use matters most. In the US, priority mostly runs from when a mark was first used in commerce rather than from the filing date, so an older business with a newer filing can still be senior to you.

Cover the state registers where you operate

The federal register is not the only one. Every state runs its own trademark register through the Secretary of State, and those records do not appear in USPTO results. A state mark cannot stop you nationally, but it can stop you in the one market that matters if that market holds your customers.

While you are on the state site, search the business entity database too. That is a different question with a different answer, and confusing the two is the most expensive naming mistake there is, as our breakdown of what an approved LLC filing does not prove sets out.

Do the common-law sweep

This is the step people skip, and it is where the expensive surprises hide. US trademark rights are created by use, not by registration. A coffee roaster that has traded under your name in three cities since 2011, with no filing of any kind, holds enforceable rights in those cities that are senior to any application you send tomorrow.

Sweep for unregistered users in this order:

• Search engines, name in quotes, then name plus your industry word, then name plus “LLC” and name plus “Inc.”
• App stores, both Apple and Google, where a huge number of active brands never register anything.
• Marketplaces: Amazon, Etsy and Shopify storefronts are full of trading names with real common-law footprints.
• Social handles on the platforms your customers use, which also tells you what you can realistically claim.
• Domains. Check the exact-match .com and the obvious variants. A .com with a live site on it is a used name; a .com parked and silent is usually an investor, not a rights holder.

If you are still generating candidates at this stage, screening for an available .com early saves rework later, which is why our free name generator checks .com availability live on every suggestion it produces.

Decide which hits actually block you

Sort what you found into three piles. Fatal: a live mark, a similar name, overlapping goods, an active owner. Walk away. Negotiable: a similar name in an adjacent category, or a common-law user two states over with no expansion plans. This is where an attorney earns the fee, and sometimes where a coexistence agreement or a narrower filing gets you through. Noise: dead records, unrelated industries, and generic words that happen to sit inside longer marks.

Be honest in the sorting. Founders quietly reclassify fatal hits as negotiable once they have fallen for a name.

Know when to stop and pay someone

The free sweep is for elimination, not approval. It reliably kills bad names, which is most of its value, and it can never tell you a name is safe. Once a candidate survives everything above and you are ready to build on it, buy a clearance opinion from a trademark attorney before you print anything, register the entity, or commit to a domain.

That order matters. Clear the name first, then secure the exact-match .com that goes with it, then file. Doing it the other way around means paying twice for the same brand.
