Search American Trademarks by Class Description: A Comprehensive Guide
Why Conduct a Thorough Trademark Search?
A search you complete before applying for a trademark registration is essential to make sure your trademark is available to register for your particular goods or services, and to ensure that no other trademark conflicts with it. Understanding how to use the USPTO's searchable database will enable you to look up the correct trademark class for your goods or services.
How to Search American Trademarks by Class Description

Trademarks are filed within classes (or categories). For instance, a clothing company would likely file within class 025. By specifying to search class 025, you will narrow your results to only show trademarks filed within that class. You can also choose to only search LIVE trademarks, DEAD trademarks, or leave it blank to search both types of trademarks.
The Importance of Selecting the Correct Trademark Class
Trademark applications are categorized using classes. Using this tool will assist you in finding your trademark class. A specimen or proof of use is a sample of your trademark as used in commerce. It is real-life evidence of how you are actually using your trademark in the marketplace, with the goods or services included in its description.
