Trademark Classes: Understanding the Categories of Trademarks

When applying for a trademark, your protection doesn’t automatically cover every product or service. Instead, your rights depend on the specific goods or services connected to your mark — defined through trademark classes, sometimes called categories of trademarks.

Each trademark class represents a distinct group of goods or services, from clothing and technology to retail or professional consulting. Choosing the right class (or classes) is one of the most important decisions you’ll make when filing a USPTO trademark application, as it determines the true scope of your protection.

A Brief History of Trademark Classification

The system of trademark classes comes from the Nice Classification (NCL) — an international framework established in 1957 to create consistency in how trademarks are categorized across borders.

The NCL allows examiners, attorneys, and business owners worldwide to “speak the same language” when identifying what a trademark protects.

In the United States, there are 45 trademark classes recognized by the U.S. Patent and Trademark Office (USPTO):

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

This classification system makes it possible for businesses with similar names to operate in different industries without creating consumer confusion. For example, “Delta” can be both an airline and a faucet manufacturer because they fall under different trademark categories.

Examples of Common Trademark Classes

Although there are 45 classes in total, most modern businesses fit into a few key ones:

• Class 9 – Technology & Software
  Covers downloadable products such as apps, software, and electronic devices. This class is essential for tech companies and digital product developers.
• Class 25 – Clothing & Apparel
  Protects apparel items like shirts, pants, and shoes. If you’re building a fashion or lifestyle brand, this is the class that keeps your brand name safe on clothing.
• Class 35 – Retail & Online Store Services
  Covers how you sell — not what you sell. This class fits businesses that curate, resell, or manage online stores.

These examples show why understanding trademark classification is so critical: your protection should match both your current business model and your future growth plans.

How to Choose the Right Trademark Class

According to the USPTO, the best way to determine the correct class is through the Trademark Electronic Search System (TESS). This tool lets you:

• Search existing marks by class
• Avoid conflicts that could lead to a “likelihood of confusion”
• Identify coordinated classes — categories that often overlap, such as clothing (Class 25) and retail store services (Class 35)

Choosing the correct class from the start helps you avoid rejection, streamline approval, and ensure your trademark reflects how your mark is actually used in commerce.

Cost of Trademark Registration

Your filing cost depends on how many classes you register under:

• Base Application Fee: $350 per class (for most filings under Sections 1 and 44)
• Additional Surcharges: May apply if descriptions are incomplete, too broad, or require custom text

While fees can increase based on complexity, a properly structured application minimizes unnecessary costs and delays. Our firm helps clients align their submissions with USPTO trademark class standards to avoid rejections or revisions.

The Complexity of Trademark Categories

Trademark classes allow flexibility, allowing businesses in different industries to use similar names — but they also add complexity.

If your products or services span multiple categories, you may need to register under more than one class for complete coverage. However, over-filing can increase costs and attract unnecessary scrutiny from examiners.

The goal is strategic coverage: protecting the most vital parts of your brand today while preparing for future expansion.
