The Nice Classification is an international classification of goods and services applied for the registration of marks. It divides items into 45 distinct classes: Classes 1 to 34 cover manufactured goods, while Classes 35 to 45 cover services.

Securing a trademark in Class 9 (software/electronics) does not automatically prevent someone from using the same name in Class 25 (clothing), unless your mark is declared a 'well-known mark' under Indian law.
