Protecting Your Business Name With a Trademark

Forming an LLC, filing a DBA (a "doing business as" name), or registering a domain name does not give you a trademark. Those are three separate systems, run by different agencies, and none of them checks whether your business name steps on someone else's brand. A trademark is a different kind of right entirely: it protects a name, logo, or slogan that you actually use to identify your goods or services in the marketplace, and it comes from using that mark in commerce, not from filing paperwork to form your company.

This matters because a lot of new owners find out the hard way — sometimes years and a lot of marketing spend later — that their LLC name or DBA was never theirs to keep. Here's how the pieces actually fit together, and what you can do now to lower your risk.

Why forming an LLC or filing a DBA doesn't protect your name

When you form an LLC or corporation with your state's Secretary of State (or equivalent state agency), that office checks one narrow thing: whether another registered entity in that state already has the identical or a confusingly similar name on file. It is not checking trademark databases, it is not checking other states, and it is not checking common names used informally by unregistered businesses. Filing a DBA (sometimes called a fictitious business name or assumed name) is even thinner protection — in most places it's just a local notice that you're operating under a name, often filed at the county level, with little or no name-conflict screening at all. Where and how you file a DBA varies by state and locality, so confirm the process with your state or county filing office.

So it's entirely possible to form an LLC, get it approved, open a bank account, and start operating — and still be infringing someone else's trademark rights the whole time. State entity approval is not a green light on the brand-name question.

What a trademark actually protects

A trademark protects a word, phrase, symbol, logo, or combination that identifies and distinguishes your goods or services from someone else's, in the minds of customers. Under U.S. law, trademark rights arise from use of the mark in commerce — actually selling goods or offering services under that name — not from registering anything. These are often called "common law" rights, and according to the U.S. Patent and Trademark Office (USPTO), they exist automatically once you're using a mark, but they're limited to the actual geographic area where you're doing business.

Federal registration with the USPTO doesn't create the underlying right, but it substantially strengthens it: a federal registration gives you a legal presumption of ownership and the exclusive right to use the mark nationwide in connection with the goods or services listed, puts the public on notice of your claim (making it harder for someone to claim they didn't know), and gives you access to federal court and certain remedies that are much harder to get with common-law rights alone. If your business sells only in one town and has no plans to expand, common-law rights combined with careful use of the mark may be enough. If your brand matters to your growth plans — franchising, e-commerce, multi-state expansion — registration is usually worth serious consideration.

Do a clearance search before you commit to a name

Before you print signage, build a website around a name, or file formation paperwork with a name you're attached to, search for existing conflicting marks. This is often called a "clearance search," and skipping it is the single most common way small business owners end up having to rebrand after they've already invested in a name.

What to do

• Search the USPTO's trademark database. The USPTO's free public search tool is at tmsearch.uspto.gov (this replaced the old TESS system, which the USPTO retired in late 2023). Search not just for an exact match but for names that sound similar, are spelled similarly, or would create the same commercial impression — trademark conflicts turn on likelihood of confusion, not identical spelling.
• Search your state's business entity database and your state's trademark registry if it has one (many states offer their own, separate state-level trademark registration — check with your state's Secretary of State or equivalent).
• Search the open internet — search engines, social media handles, industry directories — for businesses already using the name or something close to it in your line of work, even if they never registered anything.
• Check domain availability as a business step, but understand that owning a domain is not a trademark right (more on that below).
• Consider a professional search and a trademark attorney's opinion for anything beyond a purely local, low-stakes name. Attorneys and specialized search firms can check nuances — similar-sounding marks, related goods/services classes, common-law users — that a DIY search can miss.

If your search turns up a business using a similar name for similar goods or services — even if they never filed anything with the USPTO — that's a real risk signal. Common-law rights can still block you or expose you to a demand letter, even without a registration on file.

A domain name is not a trademark

Owning "yourbrand.com" means you control that specific web address. It does not mean you have any trademark right in "yourbrand" as a business name. Domain registrars don't check trademark databases before selling you a domain, and plenty of domains get registered by people with no rights to the underlying name at all. The reverse is also true: owning the trademark doesn't automatically get you the matching domain if someone else already registered it first (that's a separate, and sometimes difficult, dispute process). Treat your domain and your trademark as two different assets that both need attention — don't assume either one protects the other.

TM, SM, and ® — what the symbols actually mean

You'll see three symbols used with brand names, and they mean different things:

• ™ (TM) — you can use this next to a name or logo you're using for goods, whether or not you've filed anything with the USPTO. It signals "I'm claiming this as my trademark," but it doesn't require or prove registration.
• ℠ (SM) — the same idea, used for services rather than goods.
• ® (the registered symbol) — this one is different. It may only be used once the USPTO has actually issued a federal registration for that mark, for the goods or services covered by that registration. Using ® before your registration is granted, or for goods/services outside what's actually registered, can undermine your rights and create other legal problems.

In short: TM and SM are self-declared and free to use any time you're genuinely using a mark; ® is earned through the federal registration process and limited to what's actually registered.

Watch out for trademark scam mailers

If you do file a trademark application, expect to receive official-looking mail or email demanding payment for "registration," "monitoring," "publication," or "renewal" services. The USPTO warns that these solicitations are frequently scams — they're often designed to look like they're from the USPTO or another government agency, sometimes even using real details from your actual application (application number, filing date, your business name) pulled from public records to look convincing.

A few reliable warning signs: the letter didn't come from an "@uspto.gov" email address; it demands urgent payment or threatens loss of your rights if you don't pay immediately; it's from an organization with an official-sounding name that isn't actually the USPTO; or it asks you to pay a private company for a service the USPTO itself provides for free or at its own listed fee. The USPTO also notes that its employees will never ask for payment by wire transfer, gift card, or to a third-party address. If you're ever unsure whether a notice about your application is legitimate, verify it directly through the USPTO's own systems at uspto.gov rather than responding to the letter or calling a number it provides; you can also report a suspected scam to the Federal Trade Commission.

Where copyright fits in — and where it doesn't

Trademark and copyright are often confused, but they protect different things. Trademark protects names, logos, and slogans that identify your brand in the marketplace. Copyright protects original creative works — writing, photos, video, software code, artwork, website content — from the moment they're fixed in a tangible form. Your logo design may have both a trademark interest (as a brand identifier) and a copyright interest (as original artwork), and those can even be owned differently depending on who created it and under what agreement. If your questions are really about protecting written content, photos, videos, or other creative works you or someone you hired produced, that's a separate topic — see our coverage of copyright basics for creative and business content.

Keeping the right once you have it

Trademark rights aren't a one-time achievement — they depend on ongoing, consistent use of the mark in commerce and, for registered marks, on filing required maintenance documents with the USPTO on their schedule to keep the registration alive. Exact filing windows and maintenance deadlines depend on your specific registration and change based on federal rules, so track the deadlines the USPTO provides for your particular filing and confirm current requirements at uspto.gov rather than relying on a general timeline. Missing a maintenance deadline can cause a registration to be canceled.

A few related situations, briefly

• If your business runs into money trouble, a trademark can be a business asset, but working out what happens to your name and brand in a shutdown or reorganization is part of the bankruptcy process, which is covered elsewhere on this site.
• If a competitor or a larger company sends you a cease-and-desist letter over your name, that's a signal to get a trademark attorney involved promptly — the range of outcomes (from doing nothing wrong to needing a full rebrand) depends heavily on the specific facts and your actual first use date.

What to do, in order

1. Before you fall in love with a name, search the USPTO's trademark database at tmsearch.uspto.gov, your state's business and trademark registries, and the open internet for conflicting uses.
2. Don't assume LLC or DBA approval means the name is clear — it isn't checking for that.
3. Start using ™ or ℠ once you're genuinely using the mark, and only switch to ® after a federal registration actually issues.
4. Treat your domain name and your trademark as separate assets; secure both deliberately.
5. Be skeptical of any mailed or emailed notice demanding payment related to your trademark — verify directly with the USPTO before paying or responding.
6. For anything beyond a small, purely local, low-stakes name, talk to a trademark attorney before you file or before you commit marketing spend to a name.
