Is checking the USPTO database enough to clear a name?

No. The federal register is the most important place to look, because a federal registration can block your application and reaches the whole country. But trademark rights in the United States come from use, not registration, so a business that never filed anything can still have rights strong enough to stop you in the area where it trades. A federal search can rule a name out. It cannot rule one in.

Does the USPTO still use TESS?

No. The USPTO retired TESS in November 2023 and replaced it with a tool called Trademark Search. Guides still telling you to open TESS have not been revisited since then, which is a fair signal of how current the rest of their advice is.

What if the name is registered but the company looks dead?

Check the file on TSDR before assuming anything. A registration keeps blocking applications until it is actually cancelled or expires, whether or not the owner still trades. If maintenance filings were missed it may be due to lapse, but that is a question of record dates, not of whether the website still loads.

How long does a proper clearance search take?

The machine part takes seconds. Reading the results honestly takes longer, because the work is judgment: deciding which near misses actually matter for your goods. Budget an afternoon doing it yourself, and expect the hard part to be the marks that are similar without being identical.

How to check whether a name is already trademarked

To check whether a name is already trademarked you have to look in three places, because a name can be taken in one and clear in the other two. What a real search report looks like shows the federal one worked through.

You have a name. Before you print anything, you want to know whether somebody already owns it. It is a reasonable question with a lot of bad advice attached to it, so here is how to answer it.

A conflicting right can live in three separate places, and they do not overlap neatly.

1. The federal register

This is the one that matters most and the one you can check yourself. Every mark registered with, or applied for at, the United States Patent and Trademark Office sits in a public database. If a registered mark is confusingly similar to yours for related goods, an examining attorney can refuse your application under section 2(d) of the Lanham Act, and the owner can generally stop you nationwide.

Search it with the USPTO Trademark Search tool. Note the name: the old TESS system was retired in November 2023. Any guide still telling you to open TESS was written before then and has not been revisited since.

2. State registers

Most states run their own register through the Secretary of State. A state registration does not beat a federal one and reaches only that state, but it is evidence of use and it will turn up in a dispute. These are searched one state at a time, and the interfaces range from adequate to actively hostile.

3. Ordinary commercial use, registered nowhere

This is the part people miss, and the part that produces the surprising letters. In the United States, trademark rights arise from use in commerce, not from filing. A bakery that has traded under a name in one city for eleven years without filing a single form still has enforceable rights in that area. It appears in no register, because it is not in one.

So a clean federal search tells you the name is probably available to register. It does not tell you the name is safe to use. Those are different questions, and running them together is the most common mistake we see.

The search mistake that makes a name look clear

Most people type their exact name into the box, see nothing, and conclude they are fine. That search answers a question nobody is asking. The USPTO does not refuse applications only for identical marks. It refuses them for marks that are confusingly similar, so the search has to cover what an ordinary ear and eye would group together:

Phonetic equivalents. KWIK and QUICK, LITE and LIGHT, XPRESS and EXPRESS. The Trademark Trial and Appeal Board has said repeatedly that there is no correct pronunciation of a coined term, which cuts against you rather than for you.
Near spellings. A letter added, doubled or dropped. Plurals. Hyphens and spaces, which are routinely treated as legally insignificant.
Translations. Under the doctrine of foreign equivalents, a word from a common modern language is translated into English and then compared. LA POSADA and THE INN can collide.
The dominant part of longer marks. If your mark is two words and one is descriptive, the other is doing the legal work. Search that one on its own.

A name that survives those searches has been tested. A name that survives an exact-match query has not been tested at all.

What to do with what you find

You will almost never find nothing. You will find things that are sort of close in fields that are sort of adjacent, and the entire job is deciding which of them matter. Two questions do most of the work:

How similar are the marks in sound, appearance and meaning? Not identical: similar. See how similar is too similar.
How related are the goods or services? Identical marks coexist all the time across genuinely unrelated fields, while related goods make even a modest resemblance dangerous. See the different-industry question.

Check anything that looks live on TSDR, the USPTO document system, before relying on it being dead.

Running the federal search properly

The USPTO's search tool is more capable than the box on the front page suggests, and three habits separate a real search from a glance.

Search the dominant word on its own. If your name is two words and one of them describes what you sell, the other is carrying the legal weight. SILVER OAK CELLARS is searched as SILVER OAK, because CELLARS tells an examiner nothing about who you are.

Search sounds, not spellings. Type the way a stranger would hear it. If your name is KWIKLY, you need to see QUICKLY, QUIKLY and QUICKLEE. The register is full of deliberate misspellings for exactly this reason, and they are all cited against each other.

Widen to the goods, not just the class. Your class number is a filing convenience, and an examiner is not limited by it. Search the words that describe your product as well as the name, because that is how you find the mark sitting in a class you never thought to look at. What a class does and does not decide covers why.

Reading what comes back

A hit list is not an answer. Four things decide whether a result matters.

Is it live? Dead and abandoned marks do not block you at the USPTO. They can still carry common-law rights if the owner is trading, so a dead registration is a prompt to look at the business, not a green light.
Is it pending? An application that has not registered yet still blocks a later one. The office suspends your application behind theirs and waits, which can add many months before you learn anything.
What are the goods, exactly? Read the identification rather than the class. That wording is what an examiner compares yours against.
Who owns it, and are they still using it? Check the record on TSDR, the USPTO's document system, and then look at whether the business exists. A registration maintained by a company that folded is a different risk from one owned by a growing competitor.

Searching the use that is in no register

Common-law rights are the hardest part and the one people skip. There is no database, so you are looking for evidence of a business trading under the name:

State business registries. Secretary of State entity search, in your state and in the states you plan to sell into.
The name in quotation marks, with and without your product word. Then again with the word "trademark" or with a city name.
Social handles and app stores. A brand with an active audience is using the name in commerce even if it has filed nothing.
Domains beyond the .com. A parked domain proves nothing, but an operating site on any ending proves use.
Trade press and directories for your industry, which is where regional businesses surface that never reach the first page of a general search.

You are not trying to reach certainty. You are trying to find the business that would be annoyed, before you spend money on the name.

When you have done enough

There is no finish line, so pick a stopping rule before you start. A workable one: you have searched the name, its sound-alikes and its dominant word; you have read the identifications on everything live that looked close; you have looked for unregistered use in your own field; and the remaining hits are either dead, distant in sound, or in a field with no plausible overlap with yours. At that point the risk is sized, which is all a search can do.

The honest summary

A search can prove a name is a problem. It can never prove a name is safe, and anyone selling you that certainty is selling something that does not exist. What a good search does is turn a vague worry into a specific, sized risk you can decide about before the packaging is printed.
