Class 37 vs Class 36 — Real Estate and Construction

This is the most important class distinction for the real estate and construction sector:

ActivityCorrect ClassWhy
Building construction servicesClass 37The physical act of building
Real estate development and salesClass 36Property as a service — selling, leasing, investing
Interior design servicesClass 37Renovation and fit-out work
Real estate brokerageClass 36Financial/property transaction service
Property managementClass 36Managing property as a service
Home cleaning / housekeepingClass 37Maintenance and cleaning services
Solar panel installationClass 37Installation service
Pest control servicesClass 37Maintenance/cleaning service
💡 Real Estate Developer — File Both
A developer who both builds (Class 37) and sells/leases (Class 36) property under the same brand should file in both classes. Many Indian real estate brands file Class 36 only and miss protection for their construction service brand.

Interior Design Brands — A Fast-Growing Trademark Class

India's interior design market is growing at 18% annually, driven by urbanisation, rising income, and the modular furniture revolution. Interior design brand names face specific risks:

  • Local interior designers copying the name of established firms when entering the same city
  • Modular kitchen and furniture brands with similar names confusing homeowners
  • Online home décor aggregators (Urban Company, NoBroker Home) creating brand confusion for service providers
1
File Class 37 for interior design and renovation services — your core service class.
2
Add Class 42 if you provide 3D design software or a digital design platform for clients.
3
Add Class 20 if you also sell furniture or home décor products under your brand name.
4
Add Class 35 if you operate an online marketplace for interior design services or products.

Home Services and Facility Management Brands

India's organised home services sector (Urban Company, Housejoy, NoBroker Handyman style platforms) is growing rapidly. Brand names in this space face particular copying risks because the service is location-dependent and customers often rely on name recognition alone:
