Trademark Search: Check a Name Before You Brand It
Before you commit to a business name, run a real trademark search. Here's the 3-layer check — USPTO, Michigan, and the marketplace — and what 'confusingly similar' really means.
Falling in love with a name is easy. Finding out someone already owns it — after the logo, the signs, and the website — is the expensive part.
A trademark search is the cheap insurance most founders skip. Done right, it tells you whether a name is clear to use before you build a brand on top of it. Here's how to actually run one, what you're really looking for, and where a quick DIY check stops being enough. (Clearing names is the first thing we do in our trademark practice.)
Why search first — the cost of skipping it
Trademark rights don't come from buying a domain or registering an LLC. They come from use and registration of a mark. So a name can look "available" everywhere you checked and still belong to someone else.
Pick a name that's already taken and the bill arrives later: a cease-and-desist, a rebrand after you've built recognition, or a refused application with the filing fee gone. A search up front is a few hours; an unwind is a few thousand dollars and your momentum.
The three layers to search
A real search has three levels — most people only do the first, and that's how they get surprised.
- The federal register (USPTO). Search the USPTO Trademark Search system for marks that are registered or pending nationwide. This is the big one — a federal registration can block you across the country.
- The state level (Michigan). Check Michigan business and trademark records through LARA's business entity search. A name can be registered at the state level even if it never hit the federal register.
- The common-law marketplace. This is the layer people forget. A business using a name without registering it can still have rights in its area. Search the open web, social media handles, domain names, and industry directories for anyone already operating under the name.
You're not just hunting for exact matches
Here's the part that trips people up: trademark law doesn't ask "is it identical?" It asks "is it confusingly similar?"
A name that looks or sounds close — for related products or services — can block you even if it's spelled differently. "Kleen" vs "Clean," "Lyft" vs "Lift," a similar name in the same lane. So when you search, look wider than the exact spelling:
- Sound-alikes and look-alikes, not just exact hits
- Related goods and services, not just identical ones
- The strength of what you find — a strong, distinctive existing mark casts a wider shadow than a weak, descriptive one
If a normal customer might think two brands come from the same source, that's the problem you're searching for.
When a DIY search isn't enough
A quick "knockout" search — the kind above — is great for killing obviously-taken names early. But before you spend real money building a brand, the stakes change.
A full clearance search digs into close calls, related categories, and common-law uses that a surface search misses, and it ends with a judgment call: is this name actually safe to build on, and to register? That judgment is where an attorney earns their keep — the difference between "I didn't see anything" and "this is clear to use."
When to call ELN
If you're naming a business, a product, or a brand and you want to know it's clear before you commit, that's the moment a search pays for itself. And if you've already gotten a cease-and-desist, don't panic — there are usually more options than the letter suggests.
