You Don't Have to Trademark Your Business Name. Here's What Changes If You Do.

Written by

No. Nothing in US law requires you to register your business name as a trademark before you open, sell or advertise. Registration is optional. What it changes is how far your rights reach and how hard they are to prove, so the real question is whether those changes matter for the business you're building.

No law makes you register

You can run a business for decades under a name you never registered with the USPTO. Plenty of businesses do. The USPTO itself describes federal registration as a choice, not a condition of doing business.

Two things often get mixed up with trademark registration. The first is forming your company. Filing an LLC or a fictitious name with the state puts the name on a state business register, which is a different system with a different purpose. The USPTO's own guidance notes that business names are typically registered by state and local governments, and that using a business name doesn't necessarily count as trademark use. I cover that gap in Your LLC Is Not Your Trademark.

The second is the domain name. Registering a domain doesn't give you any trademark rights on its own either.

What you already have without registering

In the US, trademark rights come from use, not from paperwork. Once you're using a name to sell goods or services, you generally start to build what lawyers call common law rights in it.

Those rights are real, but they're narrow. The USPTO describes them as limited to the geographic area where you actually use the name, and possibly only enforceable there. A bakery known in one county doesn't automatically have rights three states away. Unregistered names also don't appear in the USPTO's database, so someone else can search, find nothing, and adopt the same name in good faith somewhere else.

You can still go to court over an unregistered name. The Lanham Act lets a business sue over a confusingly similar name whether or not the name is registered. The difference is the proof. Without a registration, you have to show from scratch that you own the name, that it works as a trademark, and where your rights begin and end.

If you want the detail on how an earlier, unregistered user and a later registrant sort out their territories, that's in the article on prior user rights.

What federal registration adds

A registration on the USPTO's principal register changes several things at once.

  • Nationwide reach. A federal registration covers the whole United States and its territories, not only the places you've sold so far.
  • A priority date. Once the registration issues, your application filing date is treated as your date of first use nationwide for the goods or services listed, except against people who used the name or filed before you did.
  • Legal presumptions. The registration certificate is prima facie evidence that the mark is valid, that you own it, and that you have the exclusive right to use it for the listed goods or services.
  • Public notice. Registration is constructive notice of your claim, so a later user generally can't argue they had no way of knowing. Your name also shows up when other people search before choosing theirs.
  • The ® symbol. You can only use it once the mark is registered. Giving notice of registration also affects whether profits and damages can be recovered in an infringement suit.
  • Customs recordation. A registration can be recorded with U.S. Customs and Border Protection, which can stop infringing imports at the border.
  • A basis for filing abroad. A US registration can support applications in other countries.

There's a longer-term benefit too. After five consecutive years of continuous use following registration, and a filing with the USPTO, the right to use the mark can become incontestable, which narrows the grounds on which someone can attack it.

What registration doesn't do

It doesn't give you the word itself. Your rights cover the name as used with your goods or services and things related to them. The same name can often be used by another business in an unrelated field.

It doesn't enforce itself. The USPTO registers trademarks, but it doesn't police them. Watching for conflicts and acting on them stays with the owner.

It isn't permanent without upkeep. A registration has to be maintained with filings between the fifth and sixth year, and again between the ninth and tenth, and every ten years after that. Miss them and the registration is canceled or expires. The schedule is laid out in Your Trademark Registration Can Die of Neglect.

And it isn't guaranteed. The USPTO examines every application and can refuse it. Two common grounds are that the name is too close to one already registered for related goods or services, or that it only describes what's being sold. A name that can't be registered federally may still be usable, and a name that's usable may still not be registrable. Those are separate questions.

When it tends to matter more, and less

Since the law leaves the choice to you, it helps to look at what you'd actually be buying.

Registration tends to matter more when the name is doing a lot of work across a wide area. Selling online to customers in many states, planning to expand, franchise or license, putting real money into packaging and advertising, or building toward a sale of the business are all situations where nationwide rights and a clean record of ownership carry weight. Some online marketplaces also tie their brand protection programs to trademarks. Amazon Brand Registry, for example, asks for an active registered trademark or a pending application.

It tends to matter less when the business is local and plans to stay that way, when the name is a short-term or test name, or when the name is so descriptive that it's unlikely to register in the first place. In those cases, common law rights in your own area may be all you'd end up with anyway. Some owners in that position look at a state registration, which protects only inside that state. I compare the two in the article on Florida's register versus the federal one.

One timing point is worth knowing whichever way you lean. Because a registration's priority runs from the filing date, waiting has a cost that's hard to see. If someone else adopts or applies for a similar name in the meantime, the order of events can decide who ends up with which rights.

The short version

You don't need a trademark registration to have a business name, and you get some rights just by using it. Registration trades a filing fee and some ongoing upkeep for wider reach, an earlier and clearer claim, and less to prove if there's ever a dispute. Whether that trade is worth it depends on how much the name matters to your plans.
