You've spent a week on the name. You test-pitched it to five friends. The .com is available. You're ready to file the LLC, buy the domain, and order business cards.
Before any of that, check whether someone else already holds trademark rights to that name. The question isn't only whether it's "registered." It's whether someone, somewhere, has the legal right to make you change it.
Below are five methods that can catch a conflict before you spend money, laid out from cheapest to most expensive. That order matters: each step is cheaper and faster than the one after it, so you can rule out bad names early and save the expensive checks for names that have already survived the free ones.
What Is a Wordmark Search? #
A wordmark 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 registered as wordmarks.
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, filed with the United States Patent and Trademark Office (USPTO). These carry the strongest rights, nationwide.
- State registrations, filed with individual states. Weaker, and geographically limited.
- Common law rights, which can arise from using a name in commerce 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 largely visual. Name conflicts are linguistic: the USPTO compares names by sound and meaning, not only by spelling. Because the two can clear or fail independently, you should search both the name and the logo. That doesn't mean they live in separate legal worlds: when a name and a design appear together as a single composite mark, the USPTO weighs the mark as a whole rather than dissecting it into unrelated parts; marks "must be compared in their entireties" (TMEP §1207.01(b)).
When a USPTO examining attorney weighs whether two wordmarks conflict, they compare the marks on appearance, sound, connotation, and overall commercial impression (USPTO):
- Sight, how the names look on paper. Swapping or dropping a single letter rarely saves a mark that still reads as the same word.
- Sound, how the names come across when spoken. The USPTO's own teaching pair is "T. Markey" versus "Tee Marquee": different spellings, same pronunciation, treated as confusingly similar (USPTO).
- Meaning, what the names connote. In a classic case, "TORNADO" and "CYCLONE" for wire fencing were held confusingly similar because they carry the same meaning (Hancock v. American Steel & Wire Co.).
A failure on any one of these can trigger a refusal. That's why "the name is spelled differently" often doesn't save you. The examiner 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) #
This is the official source. On November 30, 2023, the USPTO retired the old TESS system and replaced it with USPTO Trademark Search at tmsearch.uspto.gov (USPTO). If a guide still tells you to "search TESS," it's out of date. Every federally filed mark, whether pending, registered, dead, or abandoned, is searchable here for free.
Start with a basic search on the exact name plus at least three variations: singular and plural, with and without spaces, and common misspellings. USPTO guidance is to search variant spellings, pronunciations, and meanings, not just the exact string (USPTO: searching).
Review Live results, but don't restrict yourself to your own Nice class. Classes help organize a search; they don't decide whether a conflict exists. Related goods and services can conflict even when they sit in different classes, and the USPTO groups many of them as "coordinated" classes for exactly this reason: "They don't have to be in the same international class to be related" (USPTO: federal trademark searching; coordinated classes). For every result worth tracking, record the mark name, serial number, owner, filing date, status, class, and goods or services description.
2. Phonetic Similarity Search #
Plain-text search misses names that sound alike but are spelled differently. You need a phonetic search that catches names sounding like yours even when they're spelled nothing like it. The USPTO's "T. Markey" versus "Tee Marquee" example is exactly this problem: identical sound, different spelling (USPTO).
Algorithms like Soundex and Metaphone group names by pronunciation rather than by letters. They are a technique some search tools (LogoVerify among them) use to approximate how an examiner compares sound; they are not a USPTO-mandated standard. What the USPTO actually asks for is broader: search variant spellings, pronunciations, and meanings of your mark (USPTO: searching).
Here are the kinds of neighbors a phonetic search surfaces that a text search steps over:
- The USPTO's own training example pairs "T. Markey" with "Tee Marquee": different letters, one sound (USPTO).
- "XCEED" was refused over the registered "X-SEED" mark for identical agricultural seed, and the Federal Circuit affirmed, chiefly because the marks sound alike (In re Viterra, 671 F.3d 1358 (Fed. Cir. 2012)).
Trademarkia is one free tool that offers phonetic-aware wordmark search.
3. Common Law Trademark Search #
This step is easy to skip because no federal database covers it, yet it is the step that finds businesses with rights but no registration.
Under U.S. trademark law, the first person to use a mark in commerce in a given area can own common law rights there, even without a registration. A business that began using a name locally in good faith, before a rival's federal registration, can keep using it in its own trade area; the Burger King case in the FAQ below is the classic example. How far those rights reach depends on factors like priority, the scope of actual use, and how related the goods are.
To surface common law users:
- Google the exact name with your industry keywords: "[your name] coffee," "[your name] apparel," and so on. Look for active commercial use.
- Search the major marketplaces, including Amazon, Etsy, eBay, and Shopify storefronts.
- Check state trademark databases. Each state keeps its own registry, usually at the Secretary of State.
- Check business name registrations, meaning LLCs and DBAs in your target states.
- Search social handles on Instagram, TikTok, and X. A four-year-old @yourname account with sales activity is potential common law evidence.
4. Domain + Social Handle Check #
This isn't a trademark search, but it's a useful proxy. When a brand has owned a matching domain and built an audience under that name for years, that's worth a closer look before you commit.
What to check:
- The exact .com. Is it registered, parked, or actively selling something?
- Common variations such as .co, .shop, and .store, with the same question for each.
- Instagram, TikTok, and X handles, looking for active accounts with real audience and content.
An unregistered .com plus dormant social handles is a weak signal of availability. A registered .com with an active business behind it is a signal to investigate, not a conclusion: owning a domain isn't a trademark right, and whether that business can block you depends on what it sells, where, and since when. Treat it as a lead to run down, not a verdict.
5. When to Escalate to an Attorney #
The first four methods are things you can run yourself for free. This one isn't a default step for every founder, and you shouldn't reach for it before the free checks earn it.
Escalate to a professional comprehensive search when a name has cleared the first four methods and you're about to spend serious money on filing, branding, and packaging, or when the stakes are high enough that a wrong guess would be ruinous. A comprehensive search firm runs federal, state, common law, and international databases at once, plus business name registries and industry directories. Prices and report length vary by provider and scope, so ask for a written quote that separates the search report, the attorney's opinion, and filing work.
An attorney then reviews the report and gives you a written opinion on availability. The opinion isn't a guarantee. One practical note on filing: if you (or your business) are domiciled outside the United States, the USPTO requires you to be represented by a U.S.-licensed attorney to file and prosecute an application (USPTO: do I need an attorney). For most U.S.-based indie founders a comprehensive search is the exception, not the routine.
What Counts as a Conflict (the Bar Is Lower Than You Think) #
The standard the USPTO applies is likelihood of confusion. It doesn't mean "identical." It asks whether a reasonable consumer, seeing both marks in the marketplace, would likely think the goods come from the same source (USPTO).
Two marks can conflict when:
- The names look similar, even with different spellings.
- The names sound similar, down to phonetic equivalents.
- The names mean similar things and share a commercial impression.
- The goods or services are related rather than identical. Related goods can conflict even across different Nice classes; the class is a filing category, not the test for conflict (USPTO: federal trademark searching).
- The earlier mark is famous, in which case federal law may give it anti-dilution protection reaching beyond related goods. That protection isn't automatic for every well-known brand: dilution applies only to marks that are widely recognized by the general consuming public of the United States, among other conditions (15 U.S.C. §1125(c)).
Likelihood of confusion under Section 2(d) is a common ground for refusal, and the filing fee is not refunded when it happens. A search before you file can surface potential conflicts while changing course is still cheap.
Phonetic Similarity, the Hidden Trap #
A name can be refused even when no registered mark shares its spelling. The USPTO's position is that there's no single "correct" pronunciation of a coined mark, so two names that can be said the same way can be treated as confusingly similar, the same logic behind its "T. Markey" versus "Tee Marquee" example. In the USPTO's words, "there is no correct pronunciation of a mark because it is impossible to predict how the public will pronounce a particular mark" (TMEP §1207.01(b)).
That trap catches any name whose sound already belongs to someone else, even when you swap or drop letters to make the spelling look different. In Viterra, the applicant's XCEED was refused over the registered X-SEED for the same goods, because the two could be pronounced alike (Fed. Cir. 2012).
Check only the literal spelling in USPTO Search and you'll miss every phonetic neighbor. A good habit is to also search for how your name sounds, not just how it's typed, which is what phonetic techniques like Soundex and Metaphone try to approximate. The USPTO frames this more broadly as searching variant spellings, pronunciations, and meanings (USPTO: searching).
Red Flags: When to Pick a Different Name #
Stop and take a closer look when any of these are true:
- An identical or near-identical mark is registered live for related goods or services. Often a conflict.
- A phonetic equivalent is live for related goods or services. Also often a conflict.
- A genuinely famous mark shares your name or a close variant. Fame can reach beyond related goods under federal anti-dilution law, but only where the mark meets the statute's conditions, including wide recognition among the U.S. consuming public (15 U.S.C. §1125(c)).
- The owner of a live conflicting mark has filed oppositions before, a sign that active prosecution could mean an expensive fight.
- You found an unregistered business with the same name actively selling in your trade area. Common law rights can block you regionally with no federal registration at all.
- Multiple "Dead" marks with your name sit in your space. Don't assume that means the name is repeatedly refused. Open each record's history to read why it ended: many marks go dead for abandonment, a missed fee, or a lapsed renewal, not a refusal, and a dead status doesn't tell you whether a business still uses the name.
A red flag is a reason to slow down and investigate at this stage, and sometimes a reason to change the name. Before launch, changing a name usually means picking another one; after launch it can also mean new packaging, a new domain, and rebuilt listings.
Frequently Asked Questions #
Do I need to check if my brand name is trademarked if I haven't filed yet? #
Yes. Common law rights can start when someone uses a name in commerce, with no filing required. You can be challenged over a name no one ever registered, because a prior unregistered user may have enforceable rights in its market, depending on the validity of its mark, who used it first, the scope of its use, and how related the goods are. That is why the search matters even if you never file. In a well-known case, the owners of a restaurant in Mattoon, Illinois, who had used the name Burger King since 1957 without knowing of the national chain's earlier use (it opened its first restaurant in 1953) and registered it under Illinois law in 1959, kept the right to use it in their Mattoon market area, about a twenty-mile radius, while the chain, federally registered in 1961, won exclusive rights in the rest of Illinois (Burger King of Florida, Inc. v. Hoots, 403 F.2d 904 (7th Cir. 1968)).
How is checking a name different from checking a logo? #
A wordmark search looks for naming conflicts through sight, sound, and meaning analysis. A logo search looks for visual conflicts through design elements and image similarity. Both can come back clean for the same brand, and a conflict in either one can sink you, so run them as separate steps. (When a name and design are registered together as one composite mark, the USPTO still judges that mark as a whole.) See our How to Check If a Logo Is Trademarked: A US Search Guide.
What if I find a similar name in a totally different industry? #
It may be fine, with two caveats. First, if the earlier mark is famous and meets the conditions for anti-dilution protection, its protection can extend beyond related goods (15 U.S.C. §1125(c)). Second, goods and services can be "related" in the USPTO's view even across different classes, so "different industry" doesn't automatically mean "no conflict" (USPTO: federal trademark searching).
How much does a brand name trademark search cost? #
Free if you do it yourself with USPTO Trademark Search and free tools. A comprehensive professional search with an attorney opinion costs extra, and prices vary by provider and scope. For comparison, a Section 2(d) refusal costs you the $350-per-class base filing fee (in effect since January 18, 2025; USPTO fee schedule) plus any surcharges, all non-refundable, plus several months of waiting and any attorney fees to argue back.
Can I trademark a common word? #
Sometimes. The more descriptive a word is of your actual goods, like calling a software product "SOFTWARE," the less protectable it is. Suggestive or arbitrary uses are stronger, such as Apple for computers rather than for apples. Generic terms can't be registered for the goods or services they name, but whether a term is generic depends on what it means to consumers. In 2020 the Supreme Court held that BOOKING.COM was not generic for the company's online reservation services, because consumers did not perceive it as the name of that class of services (USPTO v. Booking.com B.V., No. 19-46 (U.S. June 30, 2020)).
What happens if I file anyway and the USPTO refuses my mark? #
You receive a Section 2(d) Office Action citing the conflicting mark, and the deadline to respond is in the notice itself. For most applications examined on or after December 3, 2022, you have three months to respond, with a single three-month extension available for a fee. Applications filed under the Madrid Protocol (Section 66(a)) instead get a six-month response period that is not extendable in that way, so read the deadline stated in your notice rather than assuming (USPTO: response time periods). Common outcomes are amending your goods or services to avoid overlap, arguing that no confusion exists, or abandoning and refiling under a different name. Either way, the original per-class fee is gone.
