How to Choose a Trademark Class? Nice Classification Guide

What is a trademark class?

A trademark registration is granted not "in general" but for specific goods and services. These goods and services are grouped under the internationally recognized Nice Classification. The classes you select in the application, and the list of goods and services you write in those classes, determine the field in which your trademark is protected.

For example, if you registered a clothing brand only in the clothing class, as a rule this registration does not provide protection in fields such as cosmetics or restaurant services. The class selection made in the application is therefore a decision that is hard to correct afterwards; a wrong selection creates either a gap in protection or unnecessary cost.

How does the Nice Classification work?

The Nice Classification consists of 45 classes in total. The structure of the classes is as follows:

• Classes 1-34 are goods classes: They cover physical products such as chemicals, paints, cosmetics, pharmaceuticals, machinery, electronic devices, clothing, food and beverages.
• Classes 35-45 are services classes: They include fields such as advertising and trade, finance, construction, telecommunications, transport, education, software services, restaurants and accommodation, and legal and personal services.

Class headings show the general scope of a class. The actual scope of protection, however, is determined by the goods and services items you write in the application. For this reason, when drafting the list you need to pay attention not only to the class number but to the content of the items. To see all the classes and sample items, you can use our trademark class guide tool.

Sample classes by common sector

The matches in the table are for guidance. The exact class is determined according to your business's actual activity and the items to be added to the list.

A trademark is not limited to a single class. More than one class can be selected in a single application; however, each additional class increases the cost and widens the possibility of opposition. For this reason, the question "Which classes do I really need?" is a better starting point than the question "Which classes are possible?"

Which questions should be answered when selecting classes?

1. What am I selling, what am I offering? A physical product, a service, or both?
2. Do I manufacture the product myself or only sell it? A manufacturer and a retailer may need different classes.
3. Which fields will I expand into in the coming period? Product or service expansions planned for the near term should be taken into account.
4. In which classes are my competitors and similar trademarks? Trademarks in the same or a similar field increase the risk of opposition.
5. Will I expand abroad? With an application through the Madrid system, the list of goods and services will be limited by the basic application in Türkiye, so the class decision becomes important from the start.

Can products in different classes be considered similar?

Yes. Even if the class numbers differ, products may be considered similar if they complement each other or are offered to the same customer base through the same sales channels. For example, a connection can be drawn between clothing (class 25) and clothing retail (class 35), or between food services (class 43) and packaged food products. For this reason, when assessing the risk of opposition or refusal, you need to look not only at trademarks in the same class but also at related classes.

The same logic applies to you as well. Even if someone else's registered trademark is not in your class, if it is in a related field you may face a claim of likelihood of confusion. This is why a similarity search before filing should not stop at class boundaries.

Why is retail service a separate matter?

Manufacturing a product and selling it in a store, on a website or in a marketplace are different activities. For a store that sells someone else's products, trade-related services (class 35) become important. A company that manufactures its own product and sells it under its own name often needs protection in both the product class and the retail services class. If you sell online, be sure to examine this distinction; the topic is covered for e-commerce sellers separately in the article on trademark protection in e-commerce.

Does the number of classes affect the fee in a trademark application?

The trademark application fee varies by the number of classes; as the number of classes increases, so does the cost. Because current official fee amounts may change, you need to confirm them from the fee schedule published by the Turkish Patent and Trademark Office (TÜRKPATENT) or from a specialist. That said, cutting the classes unrelated to your actual activity to reduce cost is fine, but skipping classes you need is a risky saving.

Why can a very broad list of goods and services be a problem?

Preparing a broad list "just in case" may seem attractive; however, it carries two important risks:

• The risk of opposition increases: Requesting protection in more fields means conflicting with more earlier trademark owners.
• The risk of non-use arises: If the trademark is not genuinely used for 5 years from registration, the risk of cancellation begins. Items that are never used are a weak point in this respect.

The right approach is to focus on items that are actually used and that are planned to be used in the near term.

What is the risk of choosing a very narrow list?

If you keep the list narrower than necessary, your protection may remain weak when someone else uses your trademark on similar products. For example, writing only "sports shoes" may not provide protection against the same mark being used for "slippers" or "bags." A balanced list should cover your main product, the side products linked to it and your natural area of growth.

A practical method for selecting classes

If you have difficulty deciding, you can apply this three-step method:

1. Write down, one by one, all the products and services that bring in revenue today.
2. Put the additions you will genuinely implement within the next one to two years in a separate column.
3. Place each item in the relevant class by finding its counterpart in the class guide, and remove unnecessary duplicates.

The resulting list often becomes the backbone of the application. For items that remain unclear, getting a specialist's opinion helps you balance both cost and risk.

Common mistakes in selecting a trademark class

• Selecting only the product class and overlooking retail services (class 35),
• Choosing the wrong class for software and apps,
• Considering the class heading sufficient and not writing the items carefully,
• Applying without researching the classes in which competitors are registered,
• Assuming that adding classes after filing will be easy.

Note: After the application is filed, it is generally not possible to add new items to the list of goods and services; only narrowing is possible. If you are going to enter a new field, a separate application may be needed. For this reason, build the list carefully before filing.

Conclusion

The right trademark class strengthens the protection of your trademark; a wrong class creates either a gap in protection or unnecessary cost.
