Yes, and it happens constantly. Two businesses can use the same name lawfully when their goods, services, or markets are far enough apart that no reasonable customer would be confused. The test is likelihood of confusion, not whether the name is taken.
Why identical names coexist
Trademark rights are tied to what you sell and to whom. DELTA is an airline, a faucet manufacturer, and a dental plan. Nobody books a flight expecting plumbing fixtures, so all three coexist.
This surprises people who assume a name is either available or not. Availability is not a property of the name. It is a property of the name in relation to specific goods and services.
When they cannot coexist
The USPTO refuses registration where there is a likelihood of confusion with an earlier mark. Two factors carry most of the weight: how similar the marks are, and how related the goods or services are.
Similarity is judged on sight, sound, and meaning. Identical spelling is not required. Marks that look different but sound the same can conflict, and so can marks with the same meaning in different words.
Relatedness is broader than identical. Goods that would plausibly come from the same source, travel through the same channels, or reach the same buyers can be related enough to conflict even when they are not the same product.
Geography matters, but less than you think
Unregistered rights arising from use are limited to the area where you actually trade. Two businesses with the same name in different states can genuinely coexist under common law.
Federal registration changes that. A registered mark gets nationwide priority as of its filing date, including in places the owner has never operated. So the local restaurant that has traded happily for a decade can find someone else has registered the name federally and now has superior rights outside its established area.
This is one of the strongest arguments for registering rather than relying on use.
What to do if you find someone with your name
- Establish who used it first, and in what class of goods or services. Priority usually follows first use in commerce, or the filing date for a registered mark.
- Look at whether the overlap is real. Different industries, different customers, and different channels all reduce the risk.
- Coexistence agreements exist. Where two parties genuinely do not compete, a written agreement defining each party's lane can resolve the issue without either side rebranding.
- Do not assume you are safe because they have not contacted you. Silence is not permission, and the cost of rebranding rises every year you wait.
What the examining attorney actually weighs
- Refusals for likelihood of confusion are decided on a set of factors, and in practice a few of them do most of the work.
- Similarity of the marks, judged on appearance, sound, and commercial impression as a whole rather than dissected element by element.
- Relatedness of the goods and services. Not whether they are identical, but whether consumers would assume they came from the same source.
- Similarity of trade channels and buyers. Products sold in the same shops to the same people conflict more readily than products that never meet.
- The strength of the earlier mark. A fanciful, well-known mark gets a wider berth than a weak, descriptive one that coexists with many similar marks.
- The care buyers take. Impulse purchases produce confusion more easily than considered, expensive ones.
Domains and social handles are a separate problem
Owning a domain gives you no trademark rights, and having a trademark does not automatically hand you the matching domain.
A name can be legally available to you as a trademark while every sensible domain and social handle is already taken. That is a commercial constraint rather than a legal one, but it is worth discovering before you commit.
Conversely, buying the domain does not clear the name. Plenty of businesses have registered a domain and built a site on a name they were never entitled to use.
If you receive a cease and desist
- Do not ignore it, and do not reply immediately. Deadlines in these letters are usually the sender's preference rather than a legal requirement.
- Establish the facts first: who used the name first, in what goods and services, and whether either party holds a registration.
- Assess whether the claim is actually good. Many demand letters overstate the scope of the sender's rights, particularly where the goods and services barely overlap.
- Then decide between rebranding, negotiating a coexistence agreement, or pushing back. All three are legitimate outcomes depending on what the facts support.
Frequently asked questions
Can I use a name that is registered in a different state?
Possibly, but state entity registration and trademark rights are different systems. A name being free at the Secretary of State says nothing about whether a federal trademark blocks you.
What if the other business is in a different industry?
That often makes coexistence possible. The further apart the goods and services, the lower the likelihood of confusion — though famous marks receive protection that reaches beyond their own category.
Who wins if we both claim the name?
Generally whoever has priority, which usually means first use in commerce or the earliest filing date for a registered mark. Registration makes proving that considerably easier.
