You've spent a week on the name. You've test-pitched it to five friends. The .com is available — surprisingly. You're ready to file the LLC, buy the domain, and order business cards.
Stop.
Before any of that, you need to check whether someone else has trademark rights to that name. Not just whether it's "registered" — whether someone, somewhere, has the legal right to make you change it.
This guide walks through the five methods that catch the conflict before you spend money, in the order a trademark attorney would actually run them.
What Is a Wordmark Search? #
A wordmark is a trademark that protects words, letters, or numbers — the text of your brand name — independent of any logo, font, or color. Coca-Cola, Apple, and Nike are all wordmarks. So is your future brand.
A wordmark search asks one question: Has anyone claimed legal rights to this name (or a name confusingly similar to it) for goods or services like mine?
That question has three layers:
- Federal registrations — marks filed with the United States Patent and Trademark Office (USPTO). Strongest rights, nationwide.
- State registrations — filed with individual state secretaries of state. Weaker, geographically limited.
- Common law rights — acquired automatically by using a name in commerce, even with no filing at all. Limited to the geographic area of actual use, but real and enforceable.
A serious search hits all three. A casual search misses two of them.
Why Brand Name Checks Differ From Logo Checks #
Logo conflicts are visual. Name conflicts are linguistic, and the USPTO treats language much more aggressively than most people expect.
When a USPTO examining attorney evaluates whether two wordmarks conflict, they consider three forms of similarity:
- Sight — how the names look on paper. "VERIDIAN" and "VIRIDIAN" look alike.
- Sound — how the names sound when spoken aloud. "KLEEN" and "CLEAN" are phonetic equivalents.
- Meaning — what the names connote. "URBAN OUTFITTERS" and "CITY APPAREL" share commercial impression.
A failure on any of these three axes can trigger a refusal. That's why "the name is spelled differently" almost never saves you. The USPTO is checking whether a regular consumer might be confused — not whether the marks are character-identical.
5 Methods to Check If a Brand Name Is Trademarked #
1. USPTO Trademark Search (Free, Authoritative) #
The official source. As of November 30, 2023, the USPTO retired the old TESS system and replaced it with Trademark Search at tmsearch.uspto.gov. Every federally filed mark — pending, registered, dead, or abandoned — is searchable here for free.
Start with a basic search on the exact name and at least three variations: singular/plural, with/without spaces, common misspellings. Filter by status ("Live") and by the Nice class that matches your goods or services.
What to record: the mark name, serial number, owner, filing date, status, class, and goods/services description for every "Live" result that shares your class.
Time required: 20-30 minutes for a thorough first pass.
2. Phonetic Similarity Search #
Plain text search misses the most common type of conflict. You need a phonetic search that catches names that sound like yours, even if they're spelled differently.
The standard phonetic algorithms — Soundex and Metaphone — group names by their pronunciation rather than their letters. A good wordmark check runs these against the USPTO database.
Examples of conflicts a phonetic search catches but a text search misses:
- "KLEEN" → "CLEAN," "CLENE," "KLENE"
- "PHIBR" → "FIBER," "FYBR"
- "NUTRA" → "NEUTRA," "NUTRAH"
Trademarkia offers free phonetic-aware wordmark search. Tools like LogoVerify run phonetic, Soundex, and Metaphone matchers in parallel against the same USPTO data, scored by class.
3. Common Law Trademark Search #
This is the step most founders skip — and the step that surfaces the conflicts that hurt the most after launch.
Under U.S. trademark law, the first person to use a mark in commerce in a geographic area owns the common law rights in that area — even if they never registered. A small bakery in Portland that's been using "SUNRISE BAKEHOUSE" for ten years has senior common law rights over a new D2C cookie brand using the same name, at least within their trade area.
How to surface common law users:
- Google the exact name + your industry keywords. "[your name] coffee," "[your name] apparel," etc. Look for active commercial use.
- Search the major marketplaces. Amazon, Etsy, eBay, Shopify storefronts.
- Check state trademark databases. Each state's Secretary of State maintains its own registry.
- Check business name registrations. LLCs and DBAs in your target states.
- Search social handles. Instagram, TikTok, X. A four-year-old @yourname account with sales activity is potential common law evidence.
4. Domain + Social Handle Check #
Not technically a trademark search, but a strong proxy. If a brand has owned a matching domain and built an audience under that name for years, they likely have common law rights worth fighting over.
What to check:
- Exact .com — is it registered, parked, or actively selling something?
- Common variations (.co, .shop, .store) — same question.
- Instagram, TikTok, X handles — active accounts with audience and content.
An unregistered .com plus dormant social handles is a weak signal of availability. A registered .com with an active business is a near-certain conflict you need to investigate.
5. Professional Comprehensive Search #
If you've passed the first four methods and you're about to spend serious money — filing fees, branding, packaging — a professional search is worth the cost.
A comprehensive search firm runs federal, state, common law, and international databases simultaneously, plus business name registries and industry-specific directories. Reports usually run 40-100 pages and cost between $500 and $2,000 depending on scope.
An attorney then reviews the report and gives you a written opinion on availability. The opinion isn't a guarantee, but it's the closest thing to one — and it documents your good-faith effort if you're ever sued.
What Counts as a Conflict (the Bar Is Lower Than You Think) #
The legal standard the USPTO applies is "likelihood of confusion." It does NOT mean "identical." It means: would a reasonable consumer, encountering both marks in the marketplace, be likely to think the goods come from the same source?
Two marks can conflict when:
- The names look similar (sight) — even with different spellings
- The names sound similar (sound) — phonetic equivalents
- The names mean similar things (meaning/commercial impression)
- The goods or services are related — not necessarily identical (T-shirts and hats are related; software and software services are related)
- The earlier mark has fame that extends beyond its registered class (Disney can stop a Disney-branded bakery even though Disney isn't in food)
The USPTO reports that roughly 1 in 5 trademark applications receives a Section 2(d) refusal for likelihood of confusion. That's a lot of $350-per-class non-refundable fees burned by founders who didn't pre-search.
Phonetic Similarity — The Hidden Trap #
You'd be surprised how often founders get refused for a mark they were sure was unique because they only checked the spelling.
The names "FEUD" and "FUDE" share zero letters but are phonetically identical. The USPTO will treat them as confusingly similar in related classes. The same goes for:
- "NIKE" and "NYKE" or "NEYK"
- "SUITE" and "SWEET" and "SUIT"
- "BYTE" and "BITE" and "BIGHT"
If you only check the literal spelling on USPTO Search, you'll miss every phonetic neighbor. The minimum bar is to run your name through a phonetic matcher (Soundex + Metaphone) against the same database, in your class.
Red Flags: When to Pick a Different Name #
Stop and reconsider when any of these are true:
- An identical or near-identical mark is registered live in your class. Almost always a conflict.
- A phonetic equivalent is live in your class. Almost always a conflict.
- A famous mark from any class shares your name or a close variant. Fame extends past class boundaries (Disney, Apple, Coca-Cola, Tesla).
- The owner of a live conflicting mark has filed oppositions before. Active prosecution = expensive to fight.
- You found an unregistered business with the same name actively selling in your trade area. Common law rights can block you regionally even without a federal registration.
- Multiple "Dead" marks exist with the same name in your class. Could mean the name keeps getting refused — same refusal will hit you.
One red flag is enough to warrant a name change at this stage. Catching it now costs you a brainstorm session. Catching it after launch costs you the brand.
Frequently Asked Questions #
Do I need to check if my brand name is trademarked if I haven't filed yet? #
Yes. Common law trademark rights start the moment someone uses a name in commerce — no filing required. You can be sued for using a name no one ever registered, and the prior user wins. The check protects you whether or not you intend to file.
How is checking a name different from checking a logo? #
A wordmark search looks for naming conflicts using sight/sound/meaning analysis. A logo search looks for visual conflicts using design elements and image similarity. Both can return clean for the same brand, but a conflict in either one can sink you. Run them as separate steps — see our guide to checking if a logo is trademarked.
What if I find a similar name in a totally different industry? #
Usually safe, with two big exceptions: (1) the mark is famous (Disney, Apple, Tesla), in which case the protection extends beyond its registered class, and (2) the industries are "related" in the USPTO's view (apparel and accessories, software and SaaS, food and beverages). Don't assume "different industry" means "different class."
How much does a brand name trademark search cost? #
Free, if you do it yourself using USPTO Trademark Search and free tools. $500-$2,000 for a comprehensive professional search with attorney opinion. For comparison, a Section 2(d) refusal costs you $350 per class in non-refundable filing fees plus 6 months of waiting plus optional attorney fees to argue back.
Can I trademark a common word? #
Sometimes. The more descriptive a word is of your actual goods (calling a software product "SOFTWARE"), the less protectable it is. Suggestive or arbitrary uses are stronger (Apple for computers, not for apples). Generic terms can never be trademarked.
What happens if I file anyway and the USPTO refuses my mark? #
You receive a Section 2(d) Office Action citing the conflicting mark. You have six months to respond. Common outcomes: amend your goods/services to avoid overlap, argue why no confusion exists, or abandon and refile under a different name. Either way, the original $350/class fee is gone.

Conclusion #
A name search isn't paperwork — it's the cheapest insurance you'll ever buy for a brand. The five methods above, in order, will catch the conflicts that ~1 in 5 founders find out about the expensive way: through a refusal, a cease & desist, or a takedown.
Start with the USPTO. Add phonetic. Layer in common law and domain checks. Pay for a comprehensive search only when you're about to spend real money. And if any red flag fires, change the name — it's cheaper than fighting for one.
