What Is Trademark Class 37? Official IP India Definition
India follows the Nice Classification (NCL) 11th Edition, an international system that groups all possible goods and services into 45 classes. IP India (Office of the Controller General of Patents, Designs and Trade Marks) uses this classification to categorise every trademark application.

This class falls under the Services category of the Nice Classification.
Which Indian Businesses Need Class 37?
The following industries and business types must file under Trademark Class 37 to protect their brands:
- Construction companies
- engineering contractors
- interior fit-out firms
- AC/plumbing installation brands
- real estate developers
India's construction and infrastructure sector is growing at 7–9% annually. With ₹11 lakh crore in PMGSY and Smart Cities budgets, construction brand names are valuable assets — protecting them via trademark prevents passing off by rival contractors.
