How to Do a Trademark Search Before You File
Before you file with the USPTO, here's a general, plain-English guide to doing a proper trademark search first.
Why a search comes before a filing fee
Filing a trademark application costs money and takes time, and the USPTO does not refund fees if your application is refused because it conflicts with an existing mark. A search done first helps you avoid spending on a mark that's unlikely to register.
Start with the free USPTO database (TESS)
The USPTO's Trademark Electronic Search System (TESS) lets you search registered and pending marks for free. It's a reasonable starting point, but it only shows federally registered and pending marks — it won't show state trademark registrations, unregistered business names, or common-law use built up simply through using a mark in commerce.
Why a thorough search goes further than TESS
A comprehensive clearance search typically also checks state trademark databases, business name registries, domain names, and general web and marketplace use, since a business using a similar name without a federal registration can still have enforceable common-law rights in the areas where it operates.
What actually counts as a conflict
A conflict generally isn't limited to an identical name. Marks that sound alike, look alike, or create a similar overall commercial impression — especially for related goods or services — can be considered confusingly similar. This is a nuanced, fact-specific judgment call.
When to bring in a professional
Because the standard for 'confusingly similar' is subjective and the cost of a refused application is real, a professional clearance search from a licensed trademark attorney is generally recommended before you file, especially for a name your business will build significant value around.
