Trademark Classes in the United States

Introduction

The USPTO (U.S. Patent and Trademark Office) classifies trademarks into 45 classes—34 for goods and 11 for services. These are also referred to as international classes, as they are based on standards set by international agreements. Trademark classes help the USPTO organize the thousands of marks registered each year and ensure consistency in the registration process. Choosing the correct class is essential for simplifying U.S. trademark registration and reducing the risk of potential infringement disputes. This article provides a detailed guide to trademark classes in the U.S. and tips on selecting the right one.

What Is a Trademark?

A trademark is a legally protected symbol, word, phrase, logo, design, or combination thereof that identifies and distinguishes the source of goods or services from others. It helps consumers recognize and differentiate products in the marketplace. Trademarks not only protect a company’s brand identity but also grant the owner exclusive rights to use the mark in commerce, preventing unauthorized use by competitors and maintaining brand integrity and consumer trust.

What Is a Trademark Class in the U.S.?

The United States Patent and Trademark Office (USPTO) classifies trademarks into 45 classes to streamline applications, determine fees, and simplify trademark searches.

Classes 1–34: Goods
Classes 35–45: Services

For example, Class 1 covers chemicals, while Class 41 includes educational and entertainment services. When filing a trademark, you must select the class(es) that accurately represent your goods or services.

Why Are Trademark Classes Important?

Selecting the correct trademark class is crucial for several reasons:

Streamlined Registration: Accurate classification ensures a smoother application process with the USPTO.
Precise Search Results: Helps identify potential conflicts with existing trademarks in the same class.
Reduced Risk of Rejection: Filing in the wrong class can lead to delays or refusal.
Fees and Scope of Protection: Filing fees depend on the number of classes, and protection is limited to the class(es) chosen.
International Considerations: Trademark classes are harmonized under the Nice Agreement, simplifying international filings.
