Before you fall for a name, search it. That’s really the whole point of this article, but let’s back up a bit. A trademark search tells you whether someone else already has legal rights to a name, phrase, or logo that’s identical to, or close enough to, whatever you’re planning to use. Skip it, and you might spend real money on signage, packaging, and a website before a cease-and-desist letter shows up and forces you to start over.
None of this requires a law degree. It does take some patience, and honestly, a willingness to dig a little past the obvious Google search. Here’s how to actually do it.
Start With the USPTO’s Trademark Search Tool
Start at the USPTO Trademark Search system. It replaced the old TESS database back in late 2023, and it covers every mark that’s ever been registered or applied for with the U.S. Patent and Trademark Office, live, dead, or somewhere in between.
There are a few ways to search once you’re in there:
- Basic word search: type the exact name or phrase you’re considering.
- Wordmark search: catches words used inside a registered mark, not just full matches.
- Design search: for logos, using design codes that describe the visual elements.
And don’t just look for an exact match. Misspellings, plurals, and anything that sounds the same when you say it out loud all count. A name doesn’t need to be identical to cause a problem. It just needs to be close enough that a customer might mix the two up.
Check the Trademark’s Status and Class
Two things matter once you find something similar: status and class. Status just means whether the mark is live, dead, or pending. A dead mark usually isn’t a real obstacle, though it’s worth a quick look at why it was abandoned before you assume it’s fair game.
Class is a bit more involved. The USPTO sorts trademarks into 45 international classes, covering everything from clothing to software to restaurant services. Two businesses can sometimes register the exact same name if they’re in unrelated industries and there’s no realistic chance of confusing customers. A bakery named “Summit” and a software company named “Summit” might both be fine. A bakery and a coffee shop named “Summit”? Probably not so simple.
Look Beyond Federal Registrations
A federal search only covers part of the picture. Trademark rights in the US also exist at the state level, and here’s the part people miss most often: a business can build common law rights just by using a name in commerce, with no registration at all.
So dig a bit further:
- Check your state’s trademark database, usually run through the Secretary of State’s office.
- Search business entity registries to see who else is already operating under that name.
- Search the web, social media, and domain registries for anything similar.
- If you’re in a niche industry, check its directories too.
Common law rights can be limited to a small geographic area, but that doesn’t mean they’re harmless. They can still block your use of a name later, and they’ve forced more than a few businesses into an expensive rebrand.
Consider a Professional Clearance Search
A do-it-yourself search is a solid starting point, but it has a ceiling. Trademark attorneys and search firms use databases built for this exact job, catching phonetic near-misses and foreign filings that a free tool just won’t surface. If you’re naming a whole company, or getting ready for a big launch, this is usually money well spent, especially if you plan to expand nationally or file for federal registration.
Once a name is cleared, the USPTO’s trademark basics page walks through the actual registration process step by step.

| USPTO Trademark Search | Free | Federal applications and registrations | Initial screening |
| State Trademark Databases | Free | State-level registrations | Businesses operating regionally |

| Professional Clearance Search | Paid | Federal, state, common law, and phonetic variations | High-stakes launches and national brands |
Common Mistakes to Avoid
Most trademark disputes trace back to a search that wasn’t thorough enough. A few things to watch for:
- Only checking for an exact match, instead of similar-sounding or similar-looking names.
- Ignoring classes that overlap with your industry, even loosely.
- Skipping the common law search because the federal database looked clear.
- Assuming an available domain name means the trademark is free too. It doesn’t.
- Filing an application before the name is actually cleared.
A thorough search now is a lot cheaper than rebranding after you’ve already built a customer base around a name that turns out to belong to someone else.
Frequently Asked Questions
How long does a trademark search take?
A quick search on the USPTO database can take 15 to 30 minutes if the name is unusual. Add in state databases, common law sources, and similar-sounding variations, and you’re looking at a few hours. A professional clearance search usually takes a few days.
Is the USPTO trademark search free to use?
Yes, it’s free for anyone with internet access. So are state databases and general web searches. Professional clearance searches through an attorney or search firm are the exception, and those usually come with a fee.
What’s the difference between a trademark search and a trademark registration?
A search just tells you whether a name or logo appears to be taken already. Registration is the actual legal process of applying for and securing trademark rights through the USPTO, which usually comes after the search confirms the name looks available.
Can I use a name if it doesn’t show up in the USPTO database?
Not automatically. It might still be protected under state law or common law if someone’s already using it in commerce, registered or not. That’s exactly why checking beyond the federal database matters.
Do I need a lawyer to search for a trademark?
Not for a basic search. Free tools handle that fine. But before a major launch or national expansion, an attorney or professional search service can catch conflicts that a DIY search tends to miss.
Searching for a trademark isn’t something you do once and forget about. It’s a habit worth building into how you name anything your business puts in front of the public. A little care upfront can save you from a painful, expensive rebrand later, and it puts you in a much stronger spot if you decide to file for registration.
