A business name that "feels" original can still land you a cease-and-desist letter, a forced rebrand, and a stack of wasted packaging. The legal test in trademark disputes isn't whether you copied a name on purpose — it's whether customers are likely to confuse your name with someone else's. The good news: the same databases trademark attorneys use for the first pass are free, public, and searchable by anyone. Here is exactly how to check if a business name is trademarked before you spend a dollar on branding.
First, understand what "trademarked" actually means
Most founders picture one thing: a name on an official register, or it's free. Reality is messier. In the United States, trademark rights come from using a name in commerce, not from registering it. A business that has been selling under a name for five years without ever filing owns real, enforceable rights in its market — and can oppose your registration — even though no database lists it.
Second, the legal standard is likelihood of confusion, not identity. A mark that sounds like yours, looks like yours, means the same thing, is spelled differently on purpose ("KlearView" vs "ClearView"), or is a translation of yours can block you just as hard as an identical match. Keep that in mind as you search: exact-match checks are only the knockout round.
Step 1: Figure out your trademark classes before you search
Trademarks aren't registered in the abstract — they're registered against classes of goods and services under the Nice Classification: 45 international classes, 1–34 for goods and 35–45 for services. A coffee shop lives in Class 30 (coffee) and Class 43 (restaurant services); a SaaS product typically sits in Class 42 (software services) and sometimes Class 9 (downloadable software).
Why this matters: a mark registered in Class 25 (clothing) is usually a smaller threat to a software business than one in a related class — but related goods still count. Examiners treat Classes 18 and 25 as related because fashion houses sell handbags as well as clothing. Write down the 1–3 classes that describe what you actually sell now, because you'll filter every search by them and you'll pay the filing fee per class if you register.
Step 2: Search the USPTO's Trademark Search (free)
The US database is at tmsearch.uspto.gov — the USPTO's cloud-based Trademark Search system. Older guides mention TESS; the USPTO retired it on November 30, 2023 and replaced it with this system. Tutorials still showing TESS screens are out of date.
Run your search like this:
- Start with the General Search. Type your exact name and hit the magnifying glass. This is your knockout check — an identical live mark in your class means you stop and pick a different name.
- Search spelling variants and sound-alikes. Plurals, abbreviations, dropped vowels, "k" for "c", the name with and without spaces. The USPTO considers every plausible pronunciation of a mark, and phonetic equivalents are a classic refusal ground.
- Use expert mode for field tags. Search the combined mark field with
CM:YOURNAME; narrow by class (IC:042for software services) or goods/services text. - Read the Status column, not just the name. "LIVE" means registered or pending and enforceable. "DEAD" means abandoned, cancelled, or expired — not necessarily free (see the results table below).
The USPTO's own guidance says its database is only part of a proper clearance: it doesn't show state trademark registrations or unregistered common-law users. A federal search is step one of six, not the whole job.
Step 3: Widen the net to Europe (free)
A brand that sells online sells internationally from day one, so check the markets you ship to. Two free tools cover the EU, and neither needs an account: TMview, the wide net — it pools trademark data from the EUIPO, national offices across the EU, and dozens of partner offices worldwide into one search; and EUIPO eSearch plus, the deep drill for EUIPO records only, with useful filters for Nice classes and figurative (logo) elements.
One EU nuance: under EU law, goods in the same class are not automatically treated as similar and goods in different classes are not automatically unrelated — the actual specification of goods and services governs. Read the specifications on conflicting marks, not just the class numbers.
Step 4: Check the UK separately (free)
Post-Brexit, the UK is its own jurisdiction. Use the UK Intellectual Property Office's "search for a trade mark" service, which covers UK registrations including the comparable UK marks created from EU registrations after Brexit. If you sell to British customers, this stop is mandatory.
Step 5: Go global with WIPO's Global Brand Database (free)
The WIPO Global Brand Database searches tens of millions of trademark records from national and international collections — including international registrations under the Madrid System. It also has an image search: upload your logo and it finds visually similar marks using image recognition, which text searches can't do.
Step 6: Search for unregistered (common-law) use
This is the step most DIY searches skip, and it's where real-world conflicts hide. Run the name through Google, marketplaces (Amazon, Etsy, App Store), social handles, and your state's business-name registry. The USPTO itself points applicants toward a comprehensive clearance search because the federal database doesn't show unregistered users with common-law rights through use.
How to read trademark search results
Status you'll see | What it means | What to do |
|---|---|---|
LIVE — registered | A federal registration in force. | Walk away unless it's in a totally unrelated class with unrelated goods. Same or related class = pick a new name. |
LIVE — pending | An application still being examined. | Treat as a live conflict until it dies. Pending marks can still become registrations and block you. |
DEAD — abandoned | The applicant gave up or failed to respond. | Not automatically free: the owner may still be using the mark (common-law rights survive abandonment). Check the marketplace before filing on a dead mark. |
DEAD — cancelled/expired | Registration lapsed (often missed maintenance filings). | Same caution as abandoned. Verify no one is actively using it, then a new application is possible. |
No exact match | Knockout check passed. | Continue to phonetic/visual variants and the international steps above before celebrating. |
Knockout search vs. comprehensive search
What you did above is a knockout search — fast, free, and good enough for shortlisting names. Before you file and before you spend serious money on branding, understand what a comprehensive search adds:
Knockout search | Comprehensive search | |
|---|---|---|
Who runs it | You, in an evening | An attorney or professional search vendor |
Sources | USPTO register + the free databases above | Federal and state registers, business names, domain records, social handles, marketplaces, foreign registers |
Catches | Identical and near-identical registered marks | Phonetic and visual variants, unregistered users, foreign filings |
Best used | Shortlisting names | Right before you file, and before you spend on branding |
Cost | Free | Typically a few hundred to over a thousand dollars |
What registration actually costs in 2026
If your searches come back clean and you decide to file in the US, the fee structure changed on January 18, 2025 and is still in force in 2026. The old TEAS Plus ($250) / TEAS Standard ($350) two-tier system was eliminated; there is now a single $350-per-class base application fee filed electronically.
- Base fee: $350 per class. A clean one-class filing that uses pre-approved wording from the USPTO's ID Manual and is complete on day one costs $350 to the office.
- Surcharges (avoidable): +$100 per class for insufficient information, +$200 per class for free-form goods/services descriptions not taken from the ID Manual, +$200 per class for each extra 1,000 characters of identification. A sloppy one-class filing can reach $650 before an examiner has looked at it.
- Maintenance: the Section 8 declaration of use is now $325 per class and Section 9 renewal is $325 per class.
- Not refunded: USPTO filing fees are non-refundable — if your application is refused over a conflict your search missed, the fee is gone. That's the economic argument for searching thoroughly first.
Six things a clean search does NOT tell you
- Common-law rights. Unregistered users can hold enforceable rights in their geographic area. No database shows all of them.
- Pending applications in small jurisdictions. Public databases lag and don't cover everything; some foreign filings surface only after examination.
- Whether your mark is distinctive enough. Generic or merely descriptive names ("Fast Plumbing") can be refused or impossible to protect, even with zero conflicts.
- State registrations. The federal database doesn't include state-level trademark registers.
- Future filings. Someone can file tomorrow for a name like yours. Monitoring matters after you file, too.
- Domain and handle conflicts. Trademark clearance doesn't tell you whether the .com is taken or the Instagram handle is free — check those separately.
Your pre-commit checklist
- Knockout search on the USPTO's Trademark Search (tmsearch.uspto.gov): exact name, variants, sound-alikes — filtered to your classes.
- TMview and EUIPO eSearch plus for the EU; UK IPO search for the UK.
- WIPO Global Brand Database for the global picture, including a logo/image search.
- Google, marketplaces, social handles, and your state business registry for unregistered use.
- Domain and handle availability (a taken .com doesn't kill a trademark, but it kills a brand).
- Run it all again for your backup names — most founders end up on their second or third choice.

FAQs
How do I check if a business name is trademarked for free?
Start with the USPTO's Trademark Search at tmsearch.uspto.gov (free, no account) for all US federal registrations and pending applications. Then check TMview and EUIPO eSearch plus for Europe, the UK IPO for Britain, and WIPO's Global Brand Database globally. Finish with Google, marketplaces, and your state business registry for unregistered use.
Is TESS still available for trademark searches?
No. The USPTO retired TESS (the Trademark Electronic Search System) on November 30, 2023, after about 23 years, and replaced it with the cloud-based Trademark Search system at tmsearch.uspto.gov. Guides still showing TESS screenshots are outdated.
Does a trademark search guarantee my name is safe?
No. A free search is a strong first filter: it catches obvious conflicts before you spend filing fees. It won't reliably catch every phonetic equivalent, unregistered common-law user, or foreign filing. That's why attorneys distinguish a knockout search from a comprehensive clearance search.
What if the name is trademarked in a different class?
It depends on how related the goods are. A clothing mark in Class 25 is usually a smaller threat to a software business than to another apparel brand, but related classes can still create a likelihood-of-confusion refusal. Read the conflicting mark's actual goods-and-services specification, not just the class number.
Can I use a name if the trademark is dead or abandoned?
Sometimes, but not automatically. A dead mark means the registration lapsed — the former owner may still be using the name and hold common-law rights. Confirm no one is actively using it in the marketplace before you file or brand around it.
How much does it cost to register a trademark in 2026?
A clean one-class US application costs $350 in USPTO fees, filed electronically; avoidable surcharges ($100–$200 per class) apply for incomplete applications or free-form descriptions. Maintenance filings (Section 8 and Section 9) are $325 per class each. Fees are non-refundable, and attorney fees for a straightforward filing typically run $500–$1,500 on top.
Do I need a trademark attorney to check a business name?
Not for the first pass — the official databases above are free and open to everyone. An attorney is worth it when you're about to file, when searches show close-but-not-identical conflicts you can't interpret, or when the brand will carry serious money. The filing fee is non-refundable, so professional review is cheap insurance on a high-stakes name.
