Your Comprehensive Guide on 45 International Trademark Classes 2024

Did you know that nearly 20% of trademark disputes arise from businesses choosing the wrong trademark class? When a company fails to categorize its products correctly, it risks losing its brand protection. That’s why selecting the right trademark classes is critical when registering your trademark.
According to the World Intellectual Property Organization (WIPO), the Nice Classification system, used worldwide, includes 45 distinct classes—34 for goods and 11 for services. This guide will help you navigate these classes, ensuring your brand receives the full protection it deserves from the start.
What Are International Trademark Classes
Over 50% of trademark rejections occur because businesses register in the wrong class. International trademark classes exist to prevent costly mistakes like this. The Nice Classification system, adopted by more than 150 countries, breaks down into 45 categories—34 for goods and 11 for services. By grouping similar products and services, this system ensures that your trademark is registered correctly, avoiding conflicts and providing clear legal protection.
Extending Trademark Classes Is Forbidden
Trademark classes can't be expanded for a good reason—it ensures fairness and order in the registration process. Here’s why this rule is crucial:
Simplifies trademark searches: It helps businesses easily search for existing trademarks, reducing confusion and the risk of overlap.
Prevents costly disputes: Without it, you could end up in legal battles over similar trademarks, risking your brand's identity.
Maintains trademark focus: Ensures trademarks are clearly linked to specific products or services, keeping them from spreading too thin across unrelated categories.
Strengthens brand protection: A focused trademark offers robust protection, making it easier to defend your brand’s uniqueness.
This system keeps your brand’s identity clear and legally protected.
Starbucks takes brand protection seriously, and they’ve had some memorable wins in court to prove it. In one case, Starbucks went after a small coffee roaster that tried to name its product “Charbucks.” Starbucks didn’t find it funny. They argued that "Charbucks" was too close to their famous name and would confuse coffee lovers. The court agreed, and Starbucks won the case.
But Starbucks isn’t alone in this game. A few years ago, Louis Vuitton sued a Korean fried chicken restaurant called “Louis Vuiton Dak” for trademark infringement. The fashion giant claimed that the restaurant’s name was riding on its luxury reputation. The court sided with Louis Vuitton, and the restaurant had to change its name and pay damages. These cases show that picking the right trademark class and keeping an eye on your brand is more than just paperwork—it’s a key part of staying in control of your business identity.
Fun fact: Trademark infringement cases in the U.S. have been steadily rising, with over 3,500 new cases filed each year. If you don’t protect your brand, someone else just might.

If you're unsure about the process, a trademark search conducted by a professional can help ensure accuracy and compliance.
What to Expect When a Trademark Is Misclassified
Imagine spending months crafting the perfect brand name, logo, and identity, only to have your trademark application rejected because you picked the wrong class. It happens more often than you’d think! The USPTO has 45 different trademark classes, each designed to cover specific goods or services. Miss the mark, and you’ll find yourself back at square one.
Take the case of a startup that filed its fitness app under a class meant for “printed materials.” Oops! They had to refile under the right class—costing them hundreds of dollars and several months of delay.
Why does this happen? Each class is super specific. If you’re selling clothes, you need to file under Class 25. Selling software? That’s Class 9. Get it wrong, and your application can get denied, leading to extra fees, paperwork headaches, and missed opportunities.
So, when in doubt, always check twice—or better yet, consult a trademark expert before hitting submit. You don’t want your perfect trademark journey to turn into a paperwork nightmare!

To Sum Up
Imagine you're a small business owner ready to launch your groundbreaking new product—a stylish eco-friendly water bottle. You’ve invested countless hours perfecting the design, sourcing sustainable materials, and planning your marketing strategy. But as you dive into trademark registration, you discover a world of complexity that could make or break your brand.
Many trademark applications face challenges due to incorrect class selection. The Nice Classification System, with its 45 distinct classes, is your guide through this maze, helping to categorize goods and services precisely. For example, if you mistakenly file your eco-bottle under the wrong class, you might end up facing legal battles with other companies or losing your trademark altogether.
Take Nike’s iconic swoosh logo. When Nike first registered their trademark, the careful selection of classes helped them avoid conflicts with other brands and secure their brand’s identity globally. Without such a system, trademarks could overlap, leading to costly disputes and confusing consumer choices.
So, as you embark on protecting your brand, remember: understanding and correctly applying for international trademark classes isn’t just a bureaucratic step—it’s a strategic move that ensures your brand stands out clearly and securely in the crowded marketplace.
