What is Trademark Class?
Key Principles of Trademark Classification:
Nature of Goods & Services:
-
The primary basis is the nature and purpose of the goods or services.
-
Goods are grouped by function, material, or field of activity.
-
Services are grouped by the type of service activity offered.
Functional Similarity:
-
Items with similar purposes are grouped together (e.g., computers and software belong to Class 9).
Intended Use:
-
How the goods are used also determines the class — for example, chemicals for industrial use (Class 1) are separate from pharmaceuticals (Class 5).
Alphabetical Order:
-
The classes are numbered for ease of reference, but the arrangement within each class follows an alphabetical index.

Trademark Classes
Classes 1–34: Goods (products, raw materials, manufactured items, etc.)
-
Classes 35–45: Services (business services, education, legal, etc.)
Example:
-
Class 9: Electronics, scientific instruments, and software
-
Class 35: Advertising & marketing services
-
Class 25: Clothing & apparel
