Trademark Search: How to Check Before You File

The single most expensive trademark mistake is filing without a proper search. A conflicting mark can force you to rebrand entirely, wasting every dollar you spent on marketing.

A search is not just a database lookup, it is a judgment call about whether your mark is confusingly similar to existing ones in the same commercial space.

Where to search

• The official trademark database for registered marks
• Common-law databases for unregistered use
• Domain registries and social media handles
• Business name registries at the state level

What to look for

• Identical or near-identical marks
• Similar marks in related goods or services
• Phonetic similarities that sound the same
• Foreign-language equivalents

Search before you commit to a name, not after you have printed the packaging, and you will avoid the most painful rebrand in business.

Beyond the database

A full search also checks common-law users who never registered, because they can still block your use in their region.

• Search the web and social media
• Check state business registries
• Ask counsel about common-law risk
