Trademark classes decide what your registration actually protects. Here is how the 45-class NICE system works, how to choose the right class, and when you need to file in more than one.
Why classes exist
A trademark is never protected in the abstract — it is protected for specific goods or services. The classification system exists to define those boundaries. India follows the international NICE classification, which sorts all goods and services into 45 classes: Classes 1–34 cover goods, and Classes 35–45 cover services.
This is why two unrelated businesses can sometimes own the same name. The same word used for cement (Class 19) and for a music streaming app (Class 9 or 41) may coexist, because consumers are unlikely to confuse the two. Your protection extends to the classes you register in — and generally no further.
How to identify your class
Start by writing down exactly what you sell. A bakery sells baked goods (Class 30) but may also offer café services (Class 43). A SaaS company provides downloadable software (Class 9) and software-as-a-service (Class 42). The trick is to separate the physical product from the service you deliver.
Common service classes are worth memorising: Class 35 covers advertising, retail and business services; Class 41 covers education and entertainment; Class 42 covers technology and software services; Class 43 covers food and lodging. Many e-commerce and marketplace businesses end up in Class 35 plus the class of their actual goods.
When you need multiple classes
If your business genuinely operates across categories, file in each relevant class. A fashion label that sells clothing (Class 25), runs retail stores (Class 35), and licenses a fragrance (Class 3) should protect all three, because a registration in Class 25 alone would not stop a rival from using the name on perfume.
Each class carries its own government fee, so multi-class filing costs more. The decision is a balance between budget and breadth: protect the classes that matter most to your core business and reputation first, and expand later as you grow into new categories.
Getting it wrong is expensive
Filing in the wrong class is one of the costliest mistakes in trademark practice. Government fees are not refunded, and you cannot simply move an application to a different class after filing — you usually have to file afresh. An incorrect class can also leave your actual products unprotected while you believe you are covered.
Because the wording of the goods/services specification and the choice of class affect both the strength of your protection and the likelihood of objections, this is the stage where professional input pays for itself most clearly.
