Why you need a trademark name search
A business name trademark search is the single most important step in validating a brand name. Domain availability tells you whether a web address is taken. A trademark search tells you whether you can legally use the name for your business. Skipping this step has cost founders everything from cease-and-desist headaches to six-figure rebrands.
Traditional trademark searches require visiting each registry separately — USPTO's TESS, EUIPO's eSearch Plus, and the UK IPO search tool — then manually comparing results across different interfaces and classification systems. It takes hours, and most founders either give up partway through or miss critical conflicts because they only search for exact matches.
Nombrio consolidates all three registries into a single, instant search. Our AI doesn't just check for your exact name — it analyses phonetic similarities, visual resemblance, and related Nice Classification classes to surface conflicts that manual searches routinely miss.
Three registries, one search
USPTO (United States)
Over 2.5 million active registrations. Covers all US trademark filings, including pending applications and intent-to-use marks.
EUIPO (European Union)
Covers EU-wide trademarks (EUTMs) across all 27 member states through a single registration system.
UK IPO (United Kingdom)
UK trademarks are separate from EU since Brexit. Essential for any business operating in the British market.
AI-powered search goes beyond exact matches
Trademark conflicts aren't limited to identical names. "Nombrio" and "Nombrea," "TechVault" and "TekVolt" — these could all be considered confusingly similar under trademark law. Nombrio's AI analyses phonetic similarity, visual resemblance, and conceptual overlap to surface potential conflicts that basic keyword searches miss entirely.
Phonetic matching
Catches sound-alike names that could be legally confusing.
Nice class analysis
Checks related trademark classes, not just your primary one.
Domain & social checks
Also checks domain availability and social media handles.

Free trademark search — frequently asked questions
- How do I do a free trademark search?
- Enter your brand or product name in the search box above. Nombrio checks the US trademark register (USPTO) for conflicting marks — including sound-alike and visually similar names, not just exact matches — and shows a clear / caution / conflict verdict instantly, free and without an account. A free account adds UK coverage, the named conflicting marks, and your exact score; the paid Clearance Report turns that into a timestamped, shareable document.
- Can I search a trademark by company name?
- Yes. Type the business or product name you want to clear and the search returns whether confusingly similar marks are already registered, along with the number of potential conflicts and the relevant Nice classification classes. The full conflicting-mark names, owners, and filing status are included in the $9.99 Clearance Report.
- Is my business name already trademarked?
- The free search tells you whether your exact name — or a phonetically or visually similar one — is already on the US register, which is the most common reason a name is unsafe to build on. A 'clear' US verdict is a strong early signal, but a complete clearance also checks the UK and EU registers — both covered on a free account.
- Is this a real trademark search or just a name generator?
- It's a real search against live trademark data, not AI-invented results. Nombrio queries the USPTO register and runs phonetic, visual, and Nice-class similarity analysis on top — the part a plain keyword lookup or a generic AI chat can't do, because they have no access to the registries.
- Do I need a trademark search before launching a brand?
- A trademark search is the single most important name-validation step. Domain availability only tells you a web address is free; a trademark search tells you whether you can legally use the name. Skipping it has cost founders cease-and-desist letters and six-figure rebrands. Running one free check before you commit is cheap insurance.
- Which registries does Nombrio search?
- USPTO (United States), EUIPO (European Union, all 27 member states), and UK IPO (United Kingdom). Without an account you get the US register plus an EU screen; a free account adds UK coverage, the named conflicts, and your exact 0–100 score. The paid Clearance Report turns all of it into a timestamped, shareable document.
