What are Trademark Classes?

If you are registering a trademark, you will be asked to register in particular “Classes.” But what are Classes, exactly?

What is a “Class” in Trademark Law?

A “Class” refers to the categories of goods and services for which a trademark is used or intended to be used. It is essentially a “bucket of related stuff” or a “collection of similar things.” Trademark registration is typically granted on a per-class basis, meaning that a single trademark application can cover multiple classes of goods and services.

The classification system used in trademark law is known as the Nice Classification system, which is maintained by the World Intellectual Property Organization (WIPO). The Nice Classification system groups goods and services into 45 classes, with each class representing a distinct category of goods or services.

Classes 1 to 34 represent goods, such as chemicals, paints, machinery, and clothing, while classes 35 to 45 represent services, such as advertising, transportation, and education. Each class is further divided into subclasses, which provide more specific descriptions of the goods or services.

When do I need a Trademark Class?

When filing a trademark application, the applicant must identify the Classes of goods and services for which the trademark is intended to be used. The trademark registration will be granted for those classes of goods and services only.

It is critical to select the correct Class(es) for your trademark. Failure to select the correct Class(es) can result in (i) inadequate protection, or (ii) rejection of your application.

Why are Trademark Classes Important?

Classes are important in trademark law because they provide a standardized framework for identifying and registering trademarks for specific categories of goods and services. This system helps to ensure that trademark registrations are precise and specific, which is crucial for enforcing trademark rights and avoiding conflicts with other similar marks.

Here are some specific reasons why classes are important in trademark law:

  1. Avoiding confusion and conflicts: The classification system helps to avoid confusion and conflicts between trademarks that are similar, but used for different types of goods or services. For example, the trademark “Apple” is registered in class 9 for computers and class 14 for watches. This means that someone else can register the same mark for a different class of goods or services, such as class 32 for beverages.
  2. Limiting the scope of protection: The classification system helps to limit the scope of protection for a trademark. A trademark is only protected for the specific goods and services it is registered for, and not for all goods and services in the marketplace. This helps to prevent trademark owners from unfairly monopolizing a particular term or phrase.
  3. Enforcing trademark rights: The classification system is important for enforcing trademark rights. If a trademark owner finds someone else using a similar mark for the same or similar goods or services in the same class, they can take legal action to stop the infringement. The classification system makes it easier to identify potential infringers and determine the scope of the infringement.
  4. International trademark registration: The Nice Classification system is used internationally, which makes it easier for trademark owners to register their marks in multiple countries. This system provides a consistent framework for identifying and registering trademarks for specific categories of goods and services, which helps streamline the trademark registration process.


Overall, the Class system is used to separate types goods and services and to maintain marks protection only with those related goods and services. It is important to select the correct Class in order to ensure adequate protection and prevent an application rejection.
