Free Trademark Name Search

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

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.
