To check if a name is already trademarked, start with a free search of the federal trademark database at tmsearch.uspto.gov, then check your state’s trademark records, then look for unregistered commercial use online. Federal registrations, state filings, and common law rights built through everyday use can each block your name, and only the first of the three shows up in the USPTO system.
Search the Federal USPTO Database
The USPTO hosts a free public search tool at tmsearch.uspto.gov. No account is needed. You can run basic word mark searches or use field tags and wildcards for more targeted queries.1United States Patent and Trademark Office. Federal Trademark Searching
For a word-based name, the USPTO recommends three steps. First, search the exact wording using the combined mark field (the “CM” tag). This is called a knock-out search: if an identical live mark comes back, you have your answer. Second, expand the search using wildcards to catch marks that contain your name alongside other words or characters. Third, search alternative spellings and pronunciations, because marks that sound alike can conflict even when spelled differently.1United States Patent and Trademark Office. Federal Trademark Searching
If your name includes a logo or design, there’s an added step. Look up the numerical design codes in the USPTO’s Design Search Code Manual and search those codes to find visually similar marks already on file.1United States Patent and Trademark Office. Federal Trademark Searching
What to Search For Beyond the Exact Name
Searching only the exact spelling is the most common mistake. A USPTO examiner compares your application against existing marks based on how they look, sound, and feel in overall commercial impression. Your search needs to reflect that. Cover phonetic equivalents, common misspellings, plural forms, and foreign-language translations. If your English-language name has a direct translation already registered, that’s a conflict.
You also need to know exactly what goods or services you plan to offer. Trademarks are organized by the Nice Classification system, which divides commercial activity into 45 classes. Classes 1 through 34 cover goods; Classes 35 through 45 cover services.2World Intellectual Property Organization. Nice Classification Class 9 covers computer software and downloadable media. Class 25 covers clothing. Two businesses can legally use the same name if they operate in completely unrelated classes, so identifying your class narrows the search to what matters.
The USPTO’s Trademark ID Manual helps you pinpoint the right classification and find acceptable wording for describing your goods or services.3United States Patent and Trademark Office. Searching the Trademark ID Manual Nailing this down at the search stage saves time later, because any application you file will need descriptions the USPTO will accept.
How to Read Your Search Results
The results page shows each mark’s text, its registration or serial number, the owner, the goods or services covered, and its current status. Check the status column first. A “live” mark is actively protected, and a new application for a similar name in a related class faces likely rejection. A “dead” mark is no longer under active prosecution or protection at the USPTO.
Don’t treat a dead mark as free. It may have gone dead because the applicant missed a filing deadline, the registration was canceled for non-renewal, or another party opposed it successfully. The former owner may still be using the name in commerce and holding common law rights in their region. They could also refile. Dead status only means the USPTO will not consider that record when evaluating new applications. It does not mean nobody has rights to the name.
Likelihood of Confusion
Examiners don’t just look for exact matches. Federal law bars registration of any mark that so closely resembles an existing mark that consumers would likely confuse the two, mistake one for the other, or be deceived about the source of the goods.4Office of the Law Revision Counsel. 15 USC 1052 – Trademarks Registrable on Principal Register
The analysis weighs several factors: how similar the marks look and sound, how related the goods or services are, whether they move through the same channels, how carefully consumers shop for those products, and how well-known the existing mark is. Not every factor carries the same weight in every case. Two marks can look different on paper but conflict if they sound identical and cover the same type of product. Identical names in unrelated industries may coexist without issue.
This is where self-conducted searches often fall short. People find no exact match and assume they’re clear, but an examiner looking at the full picture may still flag a conflict. Treat anything remotely similar in a related class as a yellow flag worth investigating before you spend money on an application.
Check State Trademark Databases
The federal database doesn’t capture every protected name. Many businesses register only at the state level, typically through the Secretary of State’s office.5United States Patent and Trademark Office. State Trademark Information Links These registrations protect the mark within that state’s borders and won’t show up federally.
Each state runs its own search tool, and the interfaces vary. Some states offer free online trademark databases; others only let you search business entity names, which isn’t quite the same thing but still useful for spotting conflicts. State registration fees typically run from around $10 to $90 depending on the jurisdiction.
State searches matter most when the business you’re checking against, or your own business, ties to a physical location or a regional customer base. A state-registered mark can block your federal application if the owner can show earlier use. The protection is geographically limited, but within that territory the rights are real and enforceable.
Search for Unregistered (Common Law) Use
Trademark rights in the United States don’t require registration at all. Federal law protects anyone using a distinctive name in commerce against others whose similar use would likely cause confusion about the source of goods or services.6Office of the Law Revision Counsel. 15 USC 1125 – False Designations of Origin, False Descriptions, and Dilution Forbidden These common law rights arise from actual use in a specific geographic area, without any government filing.7United States Patent and Trademark Office. Why Register Your Trademark
To find these unregistered marks, go beyond the official databases. Search engines are the obvious starting point. Search your proposed name in quotes, then search it alongside the type of product or service you plan to offer. Check social media platforms, business directories, and industry-specific trade publications. A small bakery in Omaha with no trademark registration still has enforceable rights to its name in that market if it used the name first.
Domain availability is another signal worth checking. If someone owns the .com version of your proposed name and is using it commercially, that’s both a practical obstacle and possible evidence of prior common law rights. Even a parked or unused domain may indicate someone is planning to use the name.
When a Domain Is the Conflict
When a domain name conflicts with a trademark, the dispute typically goes through the Uniform Domain-Name Dispute-Resolution Policy, or UDRP, administered by ICANN. If someone registered a domain in bad faith to profit from an existing trademark, the trademark holder can file a complaint with an approved dispute-resolution provider to seek transfer or cancellation.8ICANN. Uniform Domain-Name Dispute-Resolution Policy
The UDRP only helps trademark holders going after bad-faith registrations. If someone legitimately registered a domain and runs a real business there, your options are to negotiate a purchase or pick a different name. Finding this out during your search phase is far better than finding it out after you’ve printed business cards.
What Skipping the Search Can Cost
The financial exposure from launching with a conflicting name goes well beyond the cost of a search. Discovery by the trademark owner usually starts with a cease-and-desist letter. Ignoring it escalates to federal litigation, and the numbers get serious.
For counterfeit mark cases, where someone deliberately copies an established brand, federal law allows statutory damages between $1,000 and $200,000 per counterfeit mark per type of good sold. If the infringement is willful, the ceiling rises to $2,000,000 per mark.9Office of the Law Revision Counsel. 15 USC 1117 – Recovery for Violation of Rights Outside the counterfeiting context, a court can still award the trademark owner’s lost profits, your profits from the infringing use, and attorney fees in egregious cases. Add rebranding costs — new signage, packaging, website, marketing materials — and a conflict a free database search would have caught can turn into a six-figure problem.
If Your Search Comes Back Clean
A clean search puts you in position to file. The base federal application fee is $350 per class of goods or services.10United States Patent and Trademark Office. How Much Does It Cost? A clothing company that also sells accessories in a different class pays $350 for each. The fee may be lower if the application uses pre-approved descriptions from the ID Manual and meets other formatting requirements.
You can file based on current use in commerce or on a good-faith intent to use the name in the future. An intent-to-use application secures an earlier filing date than a competitor who tries to register a similar mark while you’re still getting your business off the ground.11United States Patent and Trademark Office. Trademark Applications – Intent-to-Use (ITU) Basis The trade-off is additional paperwork and fees to prove actual use before the registration can finalize. Either way, the search you did up front is what tells you whether filing is worth the money.
