Trademark Lookup

Look Up a Trademark Before You Commit

A trademark lookup tells you whether a specific mark — or marks similar to it — already exists in the federal register, state databases, or common law use. Most people start with a free lookup on the USPTO website, which searches only the federal register with exact or near-exact keyword matching.

A professional trademark lookup expands the scope to all 50 state registers and common law sources, using phonetic and semantic matching to catch conflicts that share the same sound or meaning even if the spelling is different.

What Makes Our Lookup Different

When we say "trademark lookup," we mean a full search — not a basic database query. Every lookup covers federal, state, and common law sources with the same rigor we apply to any comprehensive search. Results are ranked by risk level and reviewed by a licensed attorney.

When You Should Look Up a Trademark

Before filing a trademark application, ordering signage or packaging, launching a website under a new brand, or announcing a new product name publicly. The earlier you search, the more options you have if a conflict is identified.

How to Read Your Results

Your results include every potential conflict across all three search layers, ranked by risk level. High-risk results are marks that are closely similar and used with related goods — the combination that triggers a Section 2(d) refusal. The Search + Opinion tier includes a written attorney opinion letter evaluating each conflict.
