A founder checks the state register, finds the name available, files the LLC, buys the domain and spends three weeks on branding. Eight months later a letter arrives from a company with a registered trademark, and everything built on that name has to be unpicked. Whether to register your trademark or LLC name first matters less than doing one search before either.
This happens regularly and it is entirely preventable. The confusion at its root is that state business registration and trademark registration look like the same thing and are not remotely the same thing.
Trademark or LLC name: two systems, two different questions
When a state approves your company name, it is answering one narrow question: is this name distinguishable from other entities already registered in this state? That is a clerical check against one state's list.
It is not a statement that the name is available nationally, that nobody else has rights in it, or that you may use it commercially. The state is maintaining a register of entities, not adjudicating brand ownership.
A trademark answers an entirely different question: who has the right to use this name in commerce, for these goods or services, and to stop others from using something confusingly similar? That right can be national, and it does not care which state you registered in.
So the sentence "I registered the name, so it's mine" contains a real misunderstanding. You registered an entity. The name question is separate and has not been asked yet.
What each actually gives you
| LLC name registration | Federal trademark | |
|---|---|---|
| Geographic scope | One state | Nationwide |
| What it prevents | Another entity registering a similar name in that state | Others using a confusingly similar mark in commerce |
| Cost | Included in the formation fee | Several hundred dollars per class, plus attorney fees |
| Time | Days to weeks | Many months, sometimes over a year |
| Renewal | With the annual report | Periodic, with proof of continued use |
| Protects the brand? | No, in any meaningful sense | Yes, that is its purpose |
The bottom row is the one worth internalising. Most founders believe they have done something about their brand by registering the company. They have done something about their entity.
The order that avoids the expensive outcome
The searching matters far more than the filing, and it is nearly free.
- Search the federal trademark register for your proposed name, before anything else. This is a public database and searching it costs nothing.
- Search more broadly than exact matches. Similar spellings, similar sounds, and names in the same field. Confusing similarity is the test, not identity.
- Check who is actually trading under it. Unregistered use can still create rights in some circumstances, so a plain web search matters alongside the register.
- Check the domain, because a company whose name does not match its website creates friction at every verification step afterwards.
- Then check the state register and form the company.
- File the trademark when the brand is settled and you are trading, in the company's name.
Steps one to three cost an evening. Skipping them is what produces the letter eight months later.
Reading a search result sensibly
A search finds something similar and the natural reaction is either to panic or to dismiss it. Neither is right, because the relevant question is narrower than "does this name exist".
What matters is whether consumers would likely be confused, and that turns substantially on whether you are in the same field. An identical name used for industrial lubricants and for a children's clothing brand may well coexist, because nobody confuses the two. A similar name in the same sector is a genuine problem even if the spelling differs.
Marks are registered in classes covering categories of goods and services, and a mark registered in one class does not automatically block use in an unrelated one. This is why a search returning hits is not automatically fatal, and equally why a search returning nothing in your class is not a guarantee.
The judgement here is exactly what a trademark attorney is for, and an hour of their time at this stage is the cheapest legal advice you will ever buy.
What a rebrand actually costs
Founders underestimate this, which is why the search gets skipped.
It is not only a new logo. It is a state filing to change the entity name, a new domain, updating the website, the email addresses, the invoices, the terms and privacy policy, the bank records, the payment processor, every marketplace and directory listing, and any printed material. It is telling every existing customer that the company they paid is now called something else.
It is also the search ranking accumulated under the old name, which does not transfer cleanly. A business with two years of organic traffic loses a meaningful part of it in a rebrand even when redirects are handled properly.
Against that, an evening of searching and possibly an hour of an attorney's time is not a close comparison.
Filing as a foreign applicant
A non-resident can register a US trademark, with one practical difference: an applicant without a US address is generally required to be represented by a US-licensed attorney. That is not optional and it sets the realistic cost.
Budget the government fee per class plus attorney fees, and expect the process to take many months. Applications routinely receive office actions — formal objections requiring a response — which is normal rather than a sign of failure, and is another reason representation is required.
File in the company's name rather than your own. Filing personally and assigning to the company later is possible and adds a step, and having the mark and the trading entity match is cleaner for everything from bank reviews to an eventual sale.
Timing the application
Search early, file when the brand is settled. Those are different moments and conflating them wastes money.
Filing too early risks paying for a mark you abandon when the business changes direction, which is common in the first year. Filing too late means building recognition in a name you do not yet have rights to, and discovering the problem when the brand is worth something.
A reasonable trigger is the point at which the name is genuinely settled, you are trading under it, and you would be materially harmed by having to change it. For most small businesses that is somewhere in the first year rather than the first month.
What you have without registering
Using a name in commerce can generate some rights even without registration, typically limited to the geographic area where you actually trade and harder to enforce.
For an online business selling across the United States, that geographic limitation is awkward, and the difficulty of proving the extent of your use is exactly the problem registration solves. Unregistered rights are better than nothing and are a poor substitute for a registration when you need to stop someone.
They are, however, why a plain web search matters alongside the register. Another business trading under the name without having registered it may still be able to cause you difficulty.
The name inside the entity name
One practical nuance. Your legal entity name and your trading name need not be identical. A company can be registered as one thing and trade publicly as another, using a registered trading name where the state requires it.
This is genuinely useful. It lets you keep a neutral legal entity while the brand evolves, and it means a brand change does not always require an entity change. It also means the trademark question attaches to the trading name, which is the one customers see, rather than to whatever appears on the formation certificate.
Where a second brand is involved, the choice between a trading name and a separate company is covered in DBA vs a second LLC.
Choosing a name that is defensible in the first place
Some names are far easier to protect than others, and this is worth knowing before you fall in love with one.
Names that describe what you do are the hardest to protect. A web design company called Web Design Services has chosen a name that competitors are entitled to use descriptively, and registration is difficult or impossible. Descriptive names feel safe because they explain the business, and they are the weakest possible choice from a protection standpoint.
Names that suggest something without describing it sit in a better position — evocative rather than literal. Invented words, or ordinary words used in a context they have nothing to do with, are the strongest of all, which is why so many well-known brands are either made-up words or ordinary words applied to something unrelated.
There is a genuine trade-off here and it is not purely legal. A descriptive name tells a first-time visitor what you do, which has real marketing value for a small business with no recognition. An invented name is protectable and must be explained. Most founders are better served somewhere in the middle: distinctive enough to own, suggestive enough to make sense.
The practical point is simply to know which kind of name you are choosing. Picking a purely descriptive one is a legitimate decision; picking one while believing you will be able to stop competitors using something similar is not.
Protecting the name outside the United States
A US trademark is a US right and stops at the border, which catches founders who assume a registration is global.
If your customers are substantially in another country, or if you trade under the same name in your own country, that is a separate registration in that jurisdiction. There are international arrangements that make filing in multiple countries from a single application more manageable, and they still result in separate national rights that are examined separately.
For most small foreign-owned companies selling into the United States, the US registration is the one that matters and the others can wait. The exception is where your own country is a significant market, or where you know that someone registering the name there would cause you real difficulty. That is a question worth asking once rather than assuming either way.
Common mistakes
Treating state approval as clearance. The state checked its own list and nothing else.
Searching only for exact matches. The test is confusing similarity, which covers spellings and sounds you did not think of.
Assuming the domain settles it. Owning a domain is not a trademark right and never has been.
Filing personally rather than in the company name. Fixable, and an unnecessary extra step.
Ignoring a letter. Early responses through an attorney frequently resolve these matters far more cheaply than anything that follows silence.
The short version
Registering an LLC name protects your entity registration in one state. It does not protect your brand and it is not clearance to use the name. Those are different systems answering different questions, and a state approval tells you nothing about the second.
Search before you form, because it is nearly free and the alternative is a rebrand. File the trademark once the name is settled and you are trading, in the company's name, with an attorney if you are outside the United States. The naming rules themselves are covered in naming your LLC, and the wider preparation in documents to have ready before filing. If you would rather have the checks done before anything is filed, that is part of our formation service.
If you would rather have this handled for you, our US LLC formation service covers it end to end. For the official position, see USPTO trademarks.
