45 Trademark Categories: A Quick Guide for Dentists

When you start a dental clinic or launch a new product, protecting your brand is a must. In India the trademark system splits everything into 45 categories, called classes. Each class covers a specific type of goods or services, so you only register in the ones that match what you offer. Getting the right class helps avoid future disputes and keeps your name safe.

Why the 45 Categories Matter

Think of the classes as drawers in a filing cabinet. If you put a dental instrument in the “medical equipment” drawer (Class 10) but also sell oral care toothpaste, you’ll need a second entry in the “toothpaste and cosmetics” drawer (Class 3). Registering in the wrong drawer means competitors could still use a similar name for the services you actually provide.

For dentists, the most common classes are:

• Class 35 – advertising, business management, and online booking services.
• Class 41 – educational courses, workshops, and professional training.
• Class 44 – medical and dental services, including preventive care.
• Class 10 – dental instruments, prosthetics, and other medical devices.
• Class 3 – toothpaste, mouthwash, and other oral hygiene products.

Choosing the right mix of classes shields all parts of your practice, from the clinic itself to the products you sell.

How to Choose the Right Class for Your Dental Brand

Start by listing everything you do or plan to sell. If you only provide check‑ups, Class 44 is enough. Add a class for each product line you introduce. Don’t forget services like online consultations – those fall under Class 35.

Next, check the official Nice Classification list used in India. It’s a simple PDF that shows what each class covers. Match your items to the descriptions, and note any overlap.

When in doubt, file in more than one class. It costs a bit more upfront, but it saves headaches later. Most trademark agents recommend filing in the primary class plus any secondary classes that could be relevant as your business grows.

Finally, keep your trademark paperwork organized. Store the registration certificate, renewal reminders, and any changes in a dedicated folder. For Dentists India members, we offer a checklist you can download – it walks you through each step, from class selection to filing.

Bottom line: the 45 trademark categories might look confusing, but they’re just a way to keep your brand protected in the right places. Pick the classes that match your services and products, file early, and you’ll avoid costly disputes down the road.
