International Trademark Classes
Choose one or more of 45 International Trademark Classes for your trademark. This Complete Guide breaks down each Classes' goods or services.

There are 45 total Trademark Classes, also known as “International Classes” or simply “Classes.” The United States Patent and Trademark Office (“USPTO”) categorizes trademarks by “Classes.” The classification system is critical because trademarks identify a source of goods and/or services that distinguish the trademark from others.

A video of me explaining the trademark classes.

Each trademark must fall into one or more International Class of goods and/or services. In fact, applicants may use the International Class system to see what other marks exist in similar Classes. By checking the Trademark Classes, a trademark owner can reduce the odds of a Likelihood of Confusion refusal and reduce potential consumer confusion.

For example, two trademarks may be identical in name, but co-exist in different Classes (e.g., DOVE for soap in Class 3, and chocolate in Class 30).

International Trademark Classes
Each trademark must fall into one or more International Trademark Classes.

Here, that begs the question: What are Classes, and how many exist? Can you file in one trademark class if your name is taken in another?

What Are Trademark Classes?

First, the terms “International Trademark Classes,” “International Classes,” and “trademark classes” mean the same thing. I use them interchangeably.

In fact, every good and/or service falls into at least 1 out of 45 different International Classes. Sometimes goods and/or services may fall into more than 1 Trademark Classes.

For example, if I own a software business service that also sells downloadable digital videos, I can file in two International Classes. Accordingly, the two Trademark Classes are Class 42 for software as a service (SaaS) and Class 9 for digital videos.

If Someone Registers My Trademark in Another Class, Can I Still File?

It depends. So long neither the International Trademark Classes are unrelated (i.e., they are not “Coordinated Classes”). In addition, goods and/or services between the two must not travel in the same trade channels.

For example, DELTA is a trademark for airline services in International Class 39, and faucets in Class 11. Here, the nature of these goods and/or services are so different, and they do not travel in the same trade channels, there is no consumer confusion. On the other hand, if the goods and/or services are too close or overlapping (e.g., toys (Class 28) and electronics (Class 9) overlap), there is a higher risk of receiving a Likelihood of Confusion refusal. Accordingly, identical names can co-exist on the trademark register.

Once I File, Can I Add More International Trademark Classes?

My clients often ask me whether they can “add” an International Trademark Class after filing. The answer is “yes, but not to the same application.” In other words, if you wish to add one or more International Classes to an application, then you must file a new application with the new class(es). As such, the USPTO will allow you to “clarify or limit, but not to broaden, the identification of goods and/or services.TMEP § 1402.06.

Why Do We Need an International Trademark Class System?

The USPTO uses the term “International Class” to refer to the “Nice Agreement” – a treaty that standardized International Classes worldwide. In the past, each country used its own “code” to list the type of goods and/or services that businesses sold.

For instance, an item that the United States listed in Class 11 would approximate to Australia’s Class 20. As you can imagine, this produced irregularities when multinational corporations decided to file in more than one country. Hence, the need for one global classification system.

Are Some Key Differences Between International Trademark Classes?

Generally, there are many differences between the International Trademark Classes. However, the biggest difference is between “goods” versus “services.” As explained above, goods are found in trademark classes 1 through 34, while services are found in classes 35 through 45.

Here, goods refer to the generic term meaning an item with “economic utility or [that] satisfies an economic want.” On the other hand, a service generally refers to a business or principal “activity.”

Should I File In as Many Trademark Classes As Possible?

No. You should file in the Classes in which you are primarily either:

  • currently selling goods and/or services, or
  • in which you reasonably intend (a “bona fide intent”) to sell goods and/or services.

Selecting more than one International Class may become pricy. The USPTO trademark filing fee is multiplied by the number of International Class selected. For instance, each application is either $250 or $350. Therefore, it is easy to pay $500-$700 for two classes, or $750 to $1,050 for three trademark classes, and so on. Of course, this does not take into consideration renewals and other maintenance fees.

What Happens If I Select The Wrong International Classes?

You should be careful in selecting the appropriate International Trademark Class. Selecting the wrong International Class could lead to a rejection letter called an “Office Action.”

Related: Trademark Office Action Responses

Expanding Trademark Classes Is Prohibited

For instance, after you file a trademark, an Examining Attorney will review your application to ensure the correct International Class is selected. In addition, the Examining Attorney will attempt to review your “specimen” if filed or when eventually filed. Simply put, a specimen is simply proof of use in commerce.

Applications struck down often feature specimens not displaying the associated goods and/or services with the mark. Because “expanding” a trademark’s description (officially called an “identification”) is prohibited, the USPTO will refuse to register a trademark.

Example of Selecting the Wrong Trademark Class

For example, Al files for LUCKY-CAPONE WINERY in Class 33 for “wine bottles” as well as  “winemaker.” Because Al is so busy with his other business, Al forgets to include “wine-tasting services.” Here, Al attaches a brochure as a specimen, showing his wine bottles and their prices. In this scenario, the USPTO stops Al’s application. Here, the USPTO notes that Al only filed in Class 33, but “winemaker”, a service, is found in Class 39. In addition, Al also wants to add “wine-tasting services” too—sadly, wine-tasing is in Class 43. As such, the USPTO refuses, explaining that expanding a trademark International Class is prohibited. TMEP § 1402.06.

Accordingly, the best Al can do is to either (1) pay the extra filing fee for a winemaker in Class 39, or (2) file a new application including “winemaker” in Class 39 and “wine-tasting services” in Class 43.

Conclusion: International Classes

In summary, carefully selecting International Classes plays a major role in proper trademark filing. Mistakes here could lead to a potentially fatal Office Action refusal. As such, you should discuss your questions about Trademark Classes with your trademark attorney.
