How to Run a Trademark Search by Company Name
The exact-match search everyone runs first is the one that misses the most. Here's the full workflow: mark search, owner search, variants, sound-alikes, and the state registers.
Why searching the exact company name is only step one
A trademark search by company name usually starts the same way: type the name into the register, see zero exact matches, feel relieved. That relief is premature. Trademark conflicts are judged on likelihood of confusion, and confusion doesn't require identical strings — a name that looks similar, sounds similar, or differs by one word can block yours if it covers related goods or services. An exact-match query sees none of that.
A proper company-name search therefore has four layers: the name itself as a word mark, the company as an owner of marks, the variants (spacing, hyphens, plurals, alternate spellings), and the phonetic equivalents. Miss a layer and you can walk away confident about a name that a thirty-second wider search would have flagged. The steps below cover all four.
"Check copyright business names" — clearing up the mix-up
First, a detour worth taking, because it saves people from searching the wrong database entirely. Founders often set out to run a copyright names search or "check copyright" on a business name — a completely natural instinct, but names live in a different legal system. Copyright protects creative works — books, code, music, photos, a logo's artwork. Names, titles, and short phrases are too short to qualify for copyright at all. Trademarks protect names — words that identify who a product or service comes from. So when you want to know whether a business or product name is safe to use, the register to search is the trademark register, not the Copyright Office's catalog. (One footnote: a logo can involve both — the artwork is copyrightable, the brand use is trademark — but the name inside it is trademark territory.)
Step by step: searching the USPTO by company name
1. Search the name as a word mark
Use the USPTO's free Trademark Search tool (tmsearch.uspto.gov). Search the name exactly, then without spaces, then each distinctive word on its own. Note every live hit and what goods or services it covers.
2. Search by owner name
Run a second query against the owner field with the company's legal name. This surfaces every mark that company has filed — including brands that look nothing like the company name. It's how you find that "Northwind" the software company also owns "NW Cloud" in your class.
3. Widen to variants and sound-alikes
Search plurals, hyphenations, common misspellings, and phonetic equivalents — "Kwik" for "Quick," "Lyft"-style vowel swaps, "-ify"/"-ly" endings. Examiners and courts treat sound-alikes as potential conflicts, so your search has to as well.
4. Read status and classes, not just names
A dead application is history, not a blocker. A live registration in an unrelated class may coexist with you fine. What matters is live marks covering goods or services related to yours — our guide to trademark classes explains how to judge that.

Product name search: same workflow, different comparison
If you're clearing a product name rather than a company name, nothing about the search changes — the register treats a product name as a trademark exactly like a company name. What changes is the comparison you care about: a conflict matters when the existing mark covers goods related to your product, even if the owning company operates in a different industry overall. That's also why one company can hold a clean company name and still have a product-line conflict, or vice versa. Clear each name you'll actually put in front of customers, and clear it against the classes your product will live in.
State registers — and searching beyond the US
The federal register isn't the only list your company name has to clear. Every US state runs a Secretary of State business search covering the entities registered there — you'll need a clear result to form your LLC or corporation, though passing it creates no trademark rights (the two systems protect different things). Many states also keep their own state trademark registers, worth a look if your business is strictly local. And if you'll sell abroad, repeat the workflow on the UK IPO's search and EUIPO's eSearch — a free trademark search here covers the US, EU, and UK registers in one query. For the full picture — name, domains, and social handles together — run a complete name check, and see our walkthrough of every place a business name can be taken. Do the wide search before the commitment: the filing fee is non-refundable, and the rebrand costs far more.
Frequently asked questions
- How do I run a trademark search by company name?
- Start on the USPTO's free Trademark Search tool: search the name as a word mark first, then run a second search with the company name in the owner field to see every mark that company holds. Then widen the net — spacing and hyphen variants, plurals, alternate spellings, and phonetic equivalents — and check each hit's live/dead status and its goods and services. Finish with your state's Secretary of State business search for entity-name conflicts.
- Is checking copyright the same as checking a trademark for a business name?
- No — and the mix-up is extremely common. Copyright protects creative works: books, software, music, photos, artwork. Names, by themselves, are too short to qualify. Brand names and company names are trademark territory, so the database to search is the trademark register (USPTO in the US), not the Copyright Office's records.
- Can I search trademarks by the owner's company name?
- Yes. The USPTO's search tool lets you query the owner field, which returns every application and registration filed by that company — including marks that look nothing like the company's own name. It's the fastest way to see a competitor's whole trademark portfolio, or to check whether a name you like is already held by someone under a different word mark than you expected.
- Is a product name search different from a company name search?
- The workflow is identical, because a product name is a trademark just like a company name — the register doesn't care which one it is. The difference is which goods and services you compare against: a product name conflict matters when the existing mark covers goods related to yours, which is where trademark classes come in.
- Do I need to check state registers too?
- Yes, for a different reason. State Secretary of State searches cover entity names — whether an LLC or corporation with that name can be formed in that state. They create no trademark rights and catch no trademark conflicts, but you'll need a clear entity name to incorporate, so check both layers before committing.
- The exact company name is free — am I clear?
- Not yet. Trademark conflicts are judged on likelihood of confusion, which covers names that look or sound similar for related goods — not just identical strings. An exact-match search misses sound-alikes, near-spellings, and one-word-different variants entirely. Run a similarity-aware search (the free checker on this page does this) before treating a name as clear.
