Searching US Trademarks by Class Name: A Comprehensive Guide
When it comes to protecting your brand and intellectual property, trademark registration is an essential step. Before applying for a trademark registration, it's crucial to search US trademarks by class name to ensure that your proposed trademark is not already in use by another party and to avoid potential conflicts. In this article, we will delve into the process of searching US trademarks by class name and provide you with the necessary information to navigate the system effectively.
Understanding Trademark Classification
Trademark classification refers to the process of categorizing goods and services for trademark registration purposes. It involves assigning the appropriate class or classes to accurately describe the nature of the goods or services associated with a particular trademark. The classification system used worldwide is known as the Nice Classification.
Searching US Trademarks by Class Name
To search US trademarks by class name, you can visit the United States Patent and Trademark Office (USPTO) website and use their database search feature. You can search by trademark name, number, or applicant class numbers. The USPTO provides a convenient tool for searching trademarks by class name, allowing you to instantly check name availability and reduce legal risk before filing.
- Visit the USPTO website and navigate to the Trademark Search page.
- Click on the "Advanced Search" option and select "Search by Trademark Name" or "Search by Applicant Class Numbers."
- Enter the class name or number and click on the "Search" button.
- The system will display a list of trademarks that match your search query, including the class name, registration status, and owner information.
International Classification System
The Nice Classification is an international system of classification of goods and services used in the registration of marks. The system is divided into 45 classes, each representing a specific group of goods or services. The USPTO uses the Nice Classification system to classify trademarks, and it is essential to know the correct class or classes for your goods or services to ensure accurate search results.
Coordinated Classes
Coordinated classes are a tool for federal trademark searching. Two or more international classes can be coordinated if the goods or services in one class are closely related to the goods or services in the other. Coordinated classes are a way to narrow down your search results and make it easier to find relevant trademarks.

Using the USPTO's Trademark Database
The USPTO's trademark database is an essential resource for searching US trademarks by class name. The database contains information on registered and pending trademarks, including class names, registration status, and owner information. You can use the database to search for trademarks by class name, view filing histories, and track the status of trademark applications.
