Trademark classes are part of the international "Nice Classification" system, which categorizes goods and services into specific groups. There are 34 classes for goods (Classes 1-34) and 11 classes for services (Classes 35-45). Every trademark application filed with the USPTO must specify at least one class, clearly defining the scope of protection sought.

Why are these classes so important?

• Scope of Protection: Your trademark rights only extend to the goods and services listed in your application (and any confusingly similar ones).

• Avoiding Conflicts: Two identical or very similar trademarks can coexist if they are in completely different, unrelated classes (e.g., DELTA airlines and DELTA faucets). However, similar marks in related classes can create a "likelihood of confusion," leading to refusal.

• Filing Fees: USPTO filing fees are typically assessed per class, so accurate selection helps manage costs.

Key Aspects of Understanding Trademark Classes in the USA

1. The USPTO's ID Manual: Your Primary Resource

The USPTO provides an extensive online database called the Trademark ID Manual. This manual lists acceptable descriptions of goods and services for each class.

• Standardized Language: Always use the descriptions found in the ID Manual or very closely related language. This streamlines the examination process.

• Avoid Ambiguity: Vague or overly broad descriptions will likely result in a USPTO office action, delaying your application.

• Specificity: Be as specific as possible while still covering your actual and anticipated scope of business.

2. Goods vs. Services: Knowing the Difference

It seems simple, but distinguishing between goods and services is crucial for correct classification.

• Goods (Classes 1-34): Tangible products you sell (e.g., clothing, software, food, machinery).

  • Example: Class 9: "Computer software for project management."

• Services (Classes 35-45): Intangible services you provide (e.g., advertising, financial services, education, legal services).

  • Example: Class 35: "Marketing services." Class 45: "Legal services, namely, trademark registration services."

3. Strategic Class Selection: Don't Under-Protect or Over-Pay

Selecting the right classes requires foresight and precision.

• Current Business Activities: Start by identifying all goods and services you currently offer under your brand name.

• Future Expansion: Consider your realistic plans for business expansion within the next 3-5 years. It's often wise to cover classes for services or products you reasonably expect to offer.

• Avoid Excessive Classes: Don't file in every possible class "just in case." This significantly increases fees and can sometimes make your mark harder to clear. Focus on relevant classes where you genuinely use or intend to use your mark.

• Related Industries: Even if you don't offer a specific product, if a similar product is in a related class and could cause confusion, it might be relevant for your strategic considerations.

4. The "Likelihood of Confusion" Test and Classes

The USPTO's examining attorneys evaluate "likelihood of confusion" based on two key factors:

1. Similarity of the Marks: How similar are the names, logos, or phrases?

2. Similarity (or Relatedness) of the Goods/Services: This is where classes become paramount. Even if marks are identical, if they are for goods/services that consumers would never confuse (e.g., "APPLE" computers vs. "APPLE" records), they might coexist. However, if marks are similar and the goods/services are related, it's a problem. The USPTO's Trademark Manual of Examining Procedure (TMEP) details how relatedness is assessed.
