Imagine opening your mail to find a letter from a lawyer you have never heard of, telling you to stop using the business name you have had for three years — the one on your sign, your invoices, and your website. You did everything right: you registered the LLC with the state, filed the DBA at the county clerk, bought the domain. Surely the name is yours. Here is the uncomfortable part: none of those filings may give you the right to keep it, and one of them gives you almost no rights at all.
Business owners routinely confuse three completely different kinds of name registration, and the confusion usually surfaces at the worst possible moment — a cease-and-desist letter, a copycat across town, or an Amazon Brand Registry rejection. This guide untangles all three: what each one actually protects, what it costs, and the order to get them in.
The 30-Second Answer
| DBA (fictitious name) | LLC name (entity name) | Trademark (brand) | |
|---|---|---|---|
| What it is | A nickname your business operates under | The legal name of your company on state records | The exclusive right to use a name for specific goods or services |
| Who grants it | County or state office | Secretary of State | USPTO (federal), state, or common law through use |
| Geographic reach | Your county or state | Your state only | Nationwide (federal registration) |
| Stops others from using the name | No — multiple businesses can hold the same DBA | Only from forming a same-named entity in your state | Yes — for confusingly similar uses in your industry |
| Typical cost | $10 to $100 | $50 to $200 to form, plus annual reports | $250 to $350 per class, plus optional legal help |
| Protects personal assets | No | Yes (that is the LLC's real job) | No |
If you take one sentence from this article, make it this one: your LLC and DBA filings are administrative paperwork, and only a trademark is brand protection.
What a DBA Actually Does
DBA stands for "doing business as," and it is also called a fictitious name, assumed name, or trade name depending on your state. It exists for one boring, practical reason: to connect the name on the storefront to the legal owner behind it, so customers and creditors know who they are dealing with.
A DBA lets "Smith Enterprises LLC" operate its coffee shop as "The Coffee Corner," open a bank account in that name, and sign contracts with it. Filing is usually cheap and fast — commonly $10 to $100 at a county clerk or state office, sometimes with a newspaper-publication step. Some states charge almost nothing: Missouri's fictitious-name registration costs $7.
What a DBA does not do is much more important:
- It grants zero exclusive rights. Most DBA offices do not even check whether the name is already taken. Two unrelated businesses in the same city can legally hold the same DBA, and neither can stop the other.
- It provides no liability protection. A DBA is a name, not an entity. If you are a sole proprietor with a DBA, you are still personally on the hook for business debts.
- It is not a trademark. Holding a DBA gives you no standing to send a cease-and-desist letter or sue someone using "your" name.
Think of a DBA as a name tag at a conference. It tells people what to call you. It does not stop anyone else from printing the same name tag.
When you need one
You need a DBA whenever you operate under any name other than your exact legal name — a sole proprietor trading as anything but their own personal name, or an LLC running a product line or location under a different brand. Banks typically require the DBA certificate before they will open an account in the trade name, and some states fine you for invoicing under an unregistered name. If the name on your customer-facing materials matches your entity name letter for letter, you generally do not need one.
What an LLC Name Actually Does
When you form an LLC, the Secretary of State checks your proposed name against existing entity names in that state and rejects it if it is identical or deceptively similar to one already on file. That check feels like protection — your name was "approved," after all — but its scope is narrow: it only prevents someone else from registering a same-named entity in your state.
Everything outside that box is still open:
- Another state, same name. Your "Blue Ridge Bakery LLC" in Virginia does nothing to stop a "Blue Ridge Bakery LLC" from forming in North Carolina.
- Same state, similar brand. State examiners compare entity names, not brands. A competitor selling under a confusingly similar trade name, without forming a same-named entity, sails right past the check.
- Trademarks are invisible to the check. The Secretary of State does not search the federal trademark database. Your approved LLC name can still infringe someone else's registered trademark — and approval is no defense if they come after you.
Formation costs vary widely: Michigan charges $50, Florida $125, while New York charges $200 plus a newspaper-publication requirement that runs $395 to $1,795 depending on county. Most states also require annual or biennial reports with their own fees. That money buys you limited liability and a legal identity, but it does not buy you brand rights in any state.
The most expensive misunderstanding
The classic trap runs like this: you form the LLC, the state approves the name, you spend two years building a reputation under it, and then a company that federally trademarked a similar name years earlier sends a demand letter. Your options are rebrand (new signs, new domain, new packaging, confused customers) or fight from the weaker position — the state approval you relied on is irrelevant to the outcome. A trademark clearance search before you file formation paperwork costs nothing and prevents exactly this.
What a Trademark Actually Does
A trademark is the right to use a particular name, logo, or slogan to identify the source of specific goods or services — and to stop others in your commercial lane from using anything confusingly similar. It is the only one of the three that answers the question "can I make them stop?"
Trademark rights in the United States come in three strengths:
1. Common-law rights (automatic, weakest). The moment you start using a name in commerce — selling goods or services under it — you own limited rights in the geographic area where you actually sell. This costs nothing, but enforcing it means proving where and when you used the mark first, and your protection ends where your market presence ends. A bakery famous in one county has no common-law claim against a same-named bakery three states away.
2. State trademark registration (middle ground). Most states offer their own trademark registries for modest fees: a dated public record and some procedural advantages in state court, but protection that still stops at the state line. It suits a business that will never sell across state lines — and most businesses eventually do.
3. Federal registration with the USPTO (strongest). A federal registration gives you a nationwide presumption of ownership, the right to use the ® symbol, the ability to sue in federal court and recover enhanced damages, a basis for blocking counterfeit imports through customs, and the key to programs like Amazon Brand Registry. This is what people usually mean by "trademarking" a name.
What federal registration costs and how long it takes
The USPTO filing fee is $250 per class of goods or services on the TEAS Plus online application or $350 per class on TEAS Standard, and most small businesses file in one or two classes. (A "class" is a category like restaurant services or clothing — a bakery that also sells branded T-shirts may need two.) The fee is non-refundable even if the application is refused, which is why the free clearance search matters.
Expect the process to take roughly 12 to 18 months end to end. The USPTO currently assigns new applications to an examining attorney about 8 to 10 months after filing; if the examiner raises no objections and nobody opposes during the 30-day publication window, the registration issues after that. If the examiner objects (an "office action"), responses typically cost $300 to $1,500 in legal fees if you hire help, and a professionally drafted cease-and-desist letter runs $500 to $1,500. Budget for the possibility, not just the filing fee.
The duty nobody mentions: you must police your mark
Trademark rights come with maintenance obligations: a declaration of continued use between the fifth and sixth year, renewal every ten years, and — most importantly — actual enforcement against infringers. An owner who knowingly lets copycats operate for years can lose the ability to stop them. Registration is the beginning of brand protection, not the end of it.
Putting It Together: The Copycat Test
The differences click into place when you run each registration through the same scenario: someone opens a competing business under your name in a neighboring city.
- You hold only a DBA. You have no legal lever at all. The DBA office will happily register their identical DBA too. Your only hope is any common-law trademark right your actual sales history supports — and proving that without a registration is slow and expensive.
- You hold only an LLC. If they try to form a same-named LLC in your state, the Secretary of State blocks them. But nothing forces them to form a same-named LLC — they can operate as a sole proprietorship, a differently named entity with a DBA, or an out-of-state company, and your LLC name cannot touch any of that.
- You hold a federal trademark. You can send a cease-and-desist letter citing a registration number, oppose their trademark application if they file one, petition Amazon or other platforms to remove infringing listings, and sue for infringement in federal court if they refuse. Most disputes never reach a courtroom precisely because the registration makes the outcome predictable.
Notice what this means in reverse: if you are the newcomer with only an LLC and a DBA, and the established business holds a federal trademark, you are the one who will be rebranding. Search before you invest in signage.
Five Traps That Catch Smart Owners
1. Treating state approval as clearance. As covered above, the Secretary of State's name check is not a trademark search. Clear the name federally first, then file your entity paperwork with confidence.
2. Assuming a domain or social handle confers rights. Owning blue ridgebakery.com and the matching social accounts proves nothing about trademark ownership. Domain disputes and trademark disputes run on separate tracks, and the trademark owner can generally take the domain, not the other way around.
3. Filing in the wrong class. Trademark protection is lane-specific: a registration for restaurant services does not automatically cover your packaged sauce line or your merch. Map every current and near-future revenue stream to its class before filing, because adding classes later means a new application and a new fee.
4. Picking a name the USPTO will not protect. Descriptive names ("Portland's Best Plumbing") are weak or unregistrable; the strongest marks are suggestive, arbitrary, or invented (think of a made-up word applied to your industry). The cleverer-sounding descriptive name is often the legally weaker choice — one more reason to search and preferably get a professional opinion before committing.
5. Skipping the search because the name "feels" original. The USPTO database holds millions of live marks, and infringement turns on likelihood of confusion, not exact matches. Search the USPTO's free trademark database, your state's entity and trademark registries, and the open web (including app stores and marketplaces) for similar names in related industries.

The Sensible Order of Operations
If you are starting from zero, work in this sequence:
- Clear the name. Run the USPTO, state, and web searches described above before spending a dollar on formation or branding.
- Form the entity. File the LLC (or corporation) to get liability protection and a legal identity, using the cleared name.
- File DBAs for any operating names. Each customer-facing name that differs from the entity name gets its own registration where your state or county requires it.
- File a federal trademark application for the name that makes you money. This can run in parallel with steps 2 and 3 — the 12-to-18-month clock starts at filing, so file early.
- Calendar the maintenance. Docket the year-five declaration and the ten-year renewal the day your registration issues, and set a recurring reminder to watch for copycats.
Total DIY cost for the full stack in most states: a few hundred dollars in state fees plus $250 to $350 per trademark class. The professional-search-and-filing route costs more up front and earns it back the first time it catches a conflict your own search missed.
Your Records Are Part of Your Brand Protection
Here is the connection most formation guides skip: every filing in this article generates paperwork with dates and dollar amounts, and both matter later. Trademark priority disputes turn on dated evidence of first use in commerce — invoices, receipts, and dated sales records showing when you started selling under the name. Organizational costs (state formation fees, DBA filings, trademark application fees, legal bills) are tax-relevant startup expenses that belong in your books from day one, not reconstructed from bank statements two years later. And if you operate multiple DBAs under one entity, each trade name's income and expenses should be tracked separately so you can see which brand actually earns its keep.
That means recording each fee against the right entity and trade name as you pay it, keeping formation and registration documents where you can find them, and reconciling regularly so the numbers behind a future trademark declaration or tax return are real. If you want the mechanics, the documentation on tracking costs by project and cost center shows how plain-text accounting keeps per-entity records auditable and version-controlled — so a priority dispute or an IRS question years from now meets dated records instead of your memory.
Protect the Name Before You Build on It
Choosing a business name feels like the fun part of starting up, and it is — but the unglamorous filings underneath it decide whether the brand equity you build actually belongs to you. Clear the name, form the entity, register the DBAs, and file the trademark, in that order, and the letter in the opening paragraph becomes one you send rather than one you receive. Beancount.io provides plain-text accounting that gives you complete transparency and control over your financial data, so every formation fee and first-sale invoice stays dated, searchable, and yours to prove.
