Is That Name Trademarked? Where Trademark Rights Show Up, and Where They Don't

There's no single list of every trademarked name. A name can be protected by a federal registration, a pending federal application, a state registration, or by nothing on paper at all, just someone's use of it in business. Each of those shows up in a different place, and one of them doesn't show up in any database. So the honest answer to "is this name trademarked?" is usually "by whom, for what, and where did you look?"

"Trademarked" covers three different things

Registered marks. These are names the U.S. Patent and Trademark Office has registered. The USPTO says a federal registration creates rights throughout the entire United States and its territories, and it comes with a legal presumption that the owner owns the mark and has the right to use it.

Pending applications. Someone has applied but the mark hasn't registered yet. A pending application matters more than people expect. An earlier-filed pending application can stand in the way of yours, not only a registration. And under the Lanham Act, once a mark registers, the filing date of the application counts as constructive use of the mark nationwide, with exceptions for people who were already using it.

Unregistered, or common law, marks. Nobody is required to register a trademark. The USPTO describes common law rights as based on use of the trademark in commerce within a particular geographic area. A bakery that has used a name in its city for ten years may have rights there even though it never filed a thing. What that means for a later filer is its own topic, covered in the article on prior users who never registered.

There's a fourth layer too: state registrations. Each state keeps its own register, and the USPTO notes a state registration creates rights in that state only.

Where federal registrations and applications show up

Federal registrations and pending applications are public. The USPTO's database is called the Trademark Search system. The USPTO introduced it in 2023 as the replacement for its older system, known as TESS. The agency describes it as its federal trademark database, containing millions of trademarks, with a basic search interface and a more advanced one for complex searching.

Each record in the search results links to a second system called TSDR, short for Trademark Status and Document Retrieval. That's where you can see the details of a record and the documents in the file: who owns it, what goods or services it covers, when it was filed, and what has happened since.

Two things about this database are easy to miss.

First, it only holds federal records. The USPTO's own guidance calls a search of the federal database "one essential step" and says a comprehensive clearance search "involves many sources." State registers, business name records and the open internet are separate places.

Second, finding nothing under the exact name doesn't mean the name is free. Trademark conflicts aren't limited to identical names. The USPTO looks at marks that look alike, sound alike or have similar meanings, used for related goods or services. I go through what a plain exact-match search misses in the article on free trademark searches, and why that matters before an application in the article on searching before filing.

What "live" and "dead" mean

Every federal record carries a status, and the first thing it tells you is whether the record is live or dead.

A live application is one the USPTO has accepted and is still processing, whether it's in examination, published, or under challenge. A live registration is one that's currently on the register.

A dead application is no longer active. It was abandoned, withdrawn or finally refused. A dead registration has been removed from the register, usually because it was cancelled, surrendered or allowed to expire. A registration can be cancelled simply because the owner missed a required maintenance filing.

The difference matters because, in the USPTO's words, "Only live trademark applications and registrations can prevent your trademark from being registered."

But dead doesn't mean available. The same USPTO guidance warns not to completely disregard dead records, because they "can present other legal problems if they're still being used in commerce." A registration can lapse on paperwork while the business keeps selling under the name. In that case the federal record is dead and the common law rights may be very much alive.

Where unregistered rights show up

They don't show up in the federal database, because nobody filed anything. Common law rights come from use, so the evidence of them is wherever the use is: websites, online marketplaces, social media accounts, app stores, storefronts, trade directories.

State trademark registers and state business registries are also separate from the federal database. The USPTO's clearance guidance lists state trademark and business registries and the internet as places where conflicting names turn up.

One caution about business registries. An LLC or corporation name on file with a state is a record that a company exists under that name. It isn't a trademark registration. It can still point you to a business that's using the name with customers, which is what creates trademark rights. I explain the difference in Your LLC Is Not Your Trademark.

A name is trademarked for something, not for everything

Trademark rights attach to a name for particular goods or services. That's why the question isn't only "does someone have this name?" but "does someone have this name, or one close to it, for something related to what I sell?"

It's why the USPTO can register the same word to different owners. Its own examples are Dove for soap and Dove for ice cream bars, and Delta for faucets and Delta for air travel. It's also why a different name can still be a conflict if it looks, sounds or means the same as an existing mark in your field.

So a search result is a starting point for a judgment call, not a yes or no. The USPTO says as much: a search of its database "can't give you a clear-cut answer about whether your trademark can be registered," and its examining attorney may reach a different conclusion than you did about whether two marks are likely to be confused.

Putting it together

To know whether a name is trademarked, you need answers to four questions. Is there a live federal registration or pending application for the name or something close to it? Is it for goods or services related to yours? Is anyone using the name, or something close, without a registration? And is there a state registration where you do business?

A person can look into all four on their own. The records are public. The harder part is reading what you find: deciding whether two names are close enough, and two businesses related enough, to be a problem. That's a legal judgment, and it's where people most often get it wrong in both directions, giving up a name they could have had or filing for one they couldn't.

If you'd like to walk through your own name, the search and filing packages are laid out on the services page, and the FAQs page covers most of what people ask before a first call.
