Overview of Class 37
Trademark Class 37 is the international classification for building construction; repair; installation services. It covers all services provided by contractors or subcontractors in the building or making of permanent buildings, as well as services for restoring objects to their original condition.
Registering in Class 43 is the essential legal pillar for India’s infrastructure and real estate boom. This class protects the brand identity of companies that build and maintain the physical world—ranging from mega-construction giants (L&T, Tata Projects) and real estate developers (Godrej Properties) to specialized repair agencies (Voltas, Blue Star) and facility management firms. In a sector where physical assets and safety are paramount, a Class 37 trademark ensures that your "Build or Fix" brand is legally shielded, preventing competitors from using similar names on construction sites, service vehicles, or maintenance portals.
What is included?
- •Construction: Building of permanent structures, roads, bridges, and civil engineering projects
- •Repair: Restoring objects to their original condition (vehicles, machinery, electronics)
- •Installation: Setting up ACs, elevators, solar panels, and security systems
- •Maintenance: Upkeep and preventive maintenance of buildings and equipment
- •Cleaning: Office/industrial cleaning, window washing, and disinfecting
- •Demolition: Demolition of buildings and site clearing
- •Drilling: Mining, well drilling, and quarrying services

- •Architectural design and engineering consultancy (Class 42)

- •Installation of software (Class 42)
- •Manufacturing of machinery (Product Classes 7-11)
The Foundation of Physical Assets
Class 37 is the "Physical Labor" class. It covers the actual act of building, fixing, or cleaning. If you are the person with the hammer, wrench, or mop, your service brand belongs in Class 37. It is the core class for the entire construction and maintenance supply chain.
The Repair & Maintenance Rule: Unlike manufacturing (Class 40), Class 37 covers the restoration of an object to its original state. Whether it is a "Breakdown service" for a car or "Refurbishment" of an old building, these activities are central to Class 37 protection.
Installation Dynamics: For specialized tech companies, Class 37 covers the *physical installation* of hardware. While the device is Class 9 and the software is Class 42, the service of mounting a solar panel on a roof or installing a lift in a skyscraper is strictly Class 37.

Registration & Objection Handling
- 1. Functional Search: Conduct a thorough search in Class 37 and Class 42 (Engineering) to avoid legal conflicts with both builders and designers.
- 2. Descriptiveness: Avoid generic names like "BEST BUILDERS" or "REPAIR MASTERS". The Registrar will reject these under Section 9.
- 3. Multi-Class Strategy: For a real estate group, you must file in Class 37 (Construction) AND Class 36 (Real Estate Affairs/Leasing).
- 4. Detailed Service List: Specify the nature of the work (e.g., "Installation and maintenance of industrial HVAC systems") rather than just "Installation".
- 5. Brand Visibility: In construction, "Trade Dress" on site hoardings and worker uniforms can be used as evidence of "Well-known" status in the event of an opposition.
