Searching US Trademarks by Class Description: A Comprehensive Guide
When it comes to registering a trademark in the United States, it's essential to consider the class and description of the goods or services associated with your trademark. The US Patent and Trademark Office (USPTO) uses a classification system to categorize trademarks based on their characteristics, and understanding this system can help you navigate the registration process more effectively.
What is Trademark Classification?
Trademark classification refers to the process of assigning a class or classes to a trademark based on the type of goods or services it represents. The USPTO uses the Nice Classification system, which divides trademarks into 45 classes, with 34 classes for goods and 11 classes for services. Each class has a unique number and description that outlines the specific type of goods or services it covers.
Why is Trademark Class and Description Important?
Choosing the correct class and description for your trademark is crucial when filing a trademark registration application. It helps ensure that your trademark does not conflict with existing trademarks and allows the USPTO to accurately categorize your trademark for registration purposes.
How to Search US Trademarks by Class Description
To search for trademarks by class description, you can use the USPTO's online database, known as the TESS database. This database allows you to search for trademarks by keyword, class number, or description. You can narrow down your search by selecting specific classes or using phrases to search for exact matches.
Method 1: Searching by Class Number
When searching by class number, you can enter the specific class number you're interested in, followed by the trademark description. For example, you can search for "hair care products in Class 3." This will yield a list of trademarks that match the specific class and description.
Method 2: Searching by Description

When searching by description, you can enter a keyword or phrase related to the merchandise or service you're interested in. For example, "food trucks" or "apparel in Class 25." This will yield a list of trademarks that match the description or phrase you entered.
