How to Search US Trademarks by Class: A Comprehensive Guide
When it comes to protecting your brand and securing a unique identity for your business, conducting a thorough trademark search is an essential step. This search enables you to check the availability of your proposed brand name, logo, or slogan, ensuring that no other similar trademark conflicts with it. In the United States, the USPTO (United States Patent and Trademark Office) maintains a database of registered and pending trademarks, which can be accessed through the Trademark Electronic Search System (TESS). However, navigating this vast database can be daunting, especially for those unfamiliar with the process. In this article, we will guide you on how to search US trademarks by class effectively, using the USPTO's searchable database.
Understanding Trademark Classes

Trademark classes, also known as the USPTO International Schedule of Classes for Goods & Services, are a system used to categorize goods and services for trademark registration purposes. This classification system is essential for organizing the vast array of trademarks, facilitating searches, and ensuring that applicants provide accurate and detailed descriptions of their goods and services. There are 45 classes, each representing a broad category of goods or services. For example, a clothing company would likely file within Class 25, while a restaurant would file under Class 43.
