USPTO Trademark Search

Official US trademark search

The United States Patent and Trademark Office provides an official entry point to its trademark search system, alongside search guidance and learning resources.

This is a non-AI official resource for sellers researching trademarks. Database search results alone do not establish whether a proposed brand is available for registration or use.

Using the resource

Start with the official search page and follow the instructions for the relevant system. Some account-based functions may have additional access requirements.
