Trademark Class 37: Construction and Repair Services

Online Legal India LogoBy Online Legal India Published On 14 Apr 2025 Category Trademark

When registering a trademark, choosing the correct class is crucial. The Nice Classification System, or NCL, is an international system that categorizes goods and services into 45 classes—Classes 1–34 for goods and Classes 35–45 for services.

Among these, Trademark Class 37 specifically covers businesses engaged in:

  • Construction services
  • Installation services
  • Maintenance and repair services

If your company is involved in building, mechanical installations, maintenance of machinery or properties, this class is where your trademark should reside.

What is Trademark Class 37?

Trademark Class 37 is a service class that encompasses all building construction, repair, and installation services across industries.

This includes everything from constructing homes and commercial buildings to maintaining elevators, plumbing systems, electrical grids, and even restoring vintage cars or machinery.

This class protects the service provider’s brand name, not physical products or software used in these services.

Why is Class 37 Important?

Correct trademark classification is essential for:

Legal protection in the right domain

  • Preventing infringement or conflicts with other businesses
  • Trademark search accuracy
  • Clarity in business scope for consumers and clients
  • Enabling brand expansion into franchising or licensing

If your business provides physical labor, repairs, installations, or construction, then Class 37 is your ideal trademark class.
