How to Check If Your Business Name Is Trademarked (Without a Law Degree)

2026-04-06

Nearly half of all trademark applications filed with the USPTO get rejected. Most of those founders thought they'd checked.

You found a name you love. You Googled it. Nothing came up. You searched Instagram — handle's available. You checked domain availability — .com is gone but .ai is free. You've decided this is the one.

Before you file the LLC, order business cards, or put a dollar toward branding: check the trademark. Not because lawyers say so. Because the alternative is building something real on a name you don't own and can't protect.

This guide walks through how to do a basic trademark search yourself — what to look for, what the results mean, and where the process breaks down for most people.

Why This Matters More Than You Think

The USPTO federal trademark register contains over 2.5 million active registrations. That number doesn't include state-level marks, common-law marks (trademarks that exist simply because someone used the name in commerce, without ever registering), or international registrations that could affect your ability to expand.

In 2024, the USPTO received over 500,000 trademark applications. The first-action rejection rate — meaning applications rejected on their first review — runs around 45 to 50 percent. The most common reason isn't bad paperwork. It's that the mark conflicts with something already on the register.

The cost of finding out late isn't just the rejected application fee ($250–$350 per class). It's the rebrand. The redesign. The domain switch. The customer confusion. The legal fees if someone sends a cease-and-desist after you've already built something.

Step 1: Go to TESS

The USPTO's Trademark Electronic Search System (TESS) is the federal database of registered trademarks and pending applications. It's free to use and publicly accessible at tmsearch.uspto.gov.

TESS has three search modes. For a basic name check, use Basic Word Mark Search. Type the name you're checking into the search field. Run it as an exact match first, then run it again without the quotes to catch variations.

What you're looking at in the results: each entry will show the mark, the owner, the class (more on this below), the filing date, and the status. Status is the critical field.

Step 2: Understand the Status Field

Most people see "DEAD" next to a mark and assume they're clear. That's the first place the process breaks down.

LIVE / REGISTERED: The mark is active. A registered mark in your goods and services class is a hard conflict. Stop here.
LIVE / PENDING: Someone filed an application that hasn't been approved yet. This is still a conflict — a pending application has priority over later filings in the same class.
DEAD / CANCELLED: The registration was cancelled — but the owner may still have common-law rights if they continued using the name in commerce. Don't assume dead means free.
DEAD / ABANDONED: The application was abandoned. Lower risk than cancelled, but the same caution applies about common-law use.

Step 3: Check the Right Class

Trademarks are registered by goods and services class. There are 45 international classes — software is Class 42, clothing is Class 25, food and beverages are Class 30, and so on. The same name can be registered in multiple classes by different owners, and those registrations can coexist if the goods and services don't overlap.

This means you need to search not just for the name, but for the name in your specific class. A mark called "Summit" registered by a mountain gear company (Class 28) doesn't necessarily block you from using "Summit" for a software product (Class 42) — but it gets complicated fast, especially if both products could reach the same customers.

When you find a result, look at the Identification of Goods and Services field to understand exactly what the existing mark covers.

Step 4: Search Beyond Exact Matches

The USPTO doesn't just block exact duplicates. It blocks marks that are "confusingly similar" — meaning similar in appearance, sound, or commercial impression to an existing mark in the same or related class. This is where a basic TESS search falls short.

If you're checking "Luminary" for a candle brand, you also need to search for "Luminary's," "Luminari," "Luminaire," and any other phonetically close variations. The USPTO's own examiners are trained to catch these. Your search needs to catch them first.

TESS has an advanced search mode that supports wildcard searches — for example, searching "LUMIN*" returns all marks beginning with those letters. This is worth doing for any name before you commit to it.

What a Basic TESS Search Doesn't Cover

Even a thorough TESS search has gaps:

State registrations. Every state has its own trademark system. A mark that's not federally registered may still be protected in your state and could block you locally.
Common-law rights. Any business that's been using a name in commerce has rights to it in their geographic area, even without registration. These don't show up in TESS.
International marks. If you're planning to expand globally, marks in other countries matter. The Madrid Protocol connects 130+ countries, but TESS only shows US registrations.
Trade names vs. trademarks. A trade name (the legal name of a business) is different from a trademark (a name used to identify goods and services). Both can create conflicts.

When to Hire a Trademark Attorney

A DIY TESS search is a starting point — not a clearance. If you find no exact matches and no obvious phonetic conflicts, you've passed a basic filter. That's worth knowing. But it's not legal clearance.

Hire a trademark attorney if: the name is something you're building a serious business around, you find anything in TESS that looks close, or you're planning to file a federal trademark application. A professional clearance search typically runs $500 to $1,500 for a single class — a fraction of what a rebrand costs.

What the attorney does that TESS can't: they run searches across state registrations, common-law databases, business name directories, and international registries. They also interpret the results — which is where the judgment calls live.

The Faster Path: Check 50 Names at Once

The reason most founders skip the trademark check — or do it too late — is that checking one name at a time is slow and painful. TESS isn't built for speed. By the time you've checked five names, you've lost an hour and your enthusiasm.

NameYourThing runs USPTO trademark proximity searches across 50 AI-generated names simultaneously — before you ever see the list. Names that conflict with existing marks are filtered out. The 50 that land in your report are the ones that passed. It doesn't replace an attorney for final filing, but it eliminates the names that aren't worth pursuing before you fall in love with one.
