Why your contracting company needs trademark Classes 35, 37, 39, and 42 — and what each actually covers

Most Indian companies register a trademark as an afterthought — once the business is established and a conflict has already occurred. The smarter approach is to file a multi-class trademark application at incorporation, covering all the sectors you intend to operate in. For a project and contracting company, four trademark classes are essential.

Why multi-class matters for a contracting company

Trademark protection in India is class-specific. If you register your brand in Class 37 (construction) only, a different company can legally use the same name for manpower services (Class 35) or logistics (Class 39). In a multi-sector business like Blue Projects — where we operate in construction welfare, survey operations, AI data collection, and logistics — protecting only one class leaves significant gaps.

The Indian Trademark Registry allows you to file a single multi-class application covering multiple classes simultaneously. This is cheaper than filing separate applications and establishes a unified filing date across all classes.

Class 37 — Construction, Installation, and Repair

This is the foundation class for any technical contracting company. It covers civil construction and site preparation, installation of machinery and equipment, electrical contracting and maintenance, road and infrastructure works, and repair and maintenance services of any kind. If your company bids on CPPP civil tenders, NHAI contracts, IREPS works, or any construction board programmes, Class 37 is your primary protection.

Class 35 — Business Management and Administration

This class is essential for the non-technical side of your business — and often overlooked by technical companies. Class 35 covers business management consulting, manpower supply and staffing, administrative services for businesses, data processing and compilation services, and advertising and marketing services. For Blue Projects, this class protects our survey operations, data collection services, manpower supply contracts, and election management work.

Class 42 — Scientific, Technological, and Engineering Services

As we expand into AI data collection, computer vision, and R&D project execution, Class 42 becomes increasingly important. It covers scientific research and development, technology consulting and advisory, software development and IT services, engineering design services, and AI and machine learning services. This is the class that protects our AI data platform work, DRDO project support, IIT/IISc lab contract work, and any technology-enabled field observation services.

Class 39 — Transport and Logistics

Any company involved in goods movement, supply chain management, or last-mile distribution needs Class 39. For Blue Projects, this covers our welfare kit distribution work, logistics coordination for field projects, warehousing support, and transport management for equipment and materials. As we expand into supply chain-intensive EPC contracts, this protection becomes more valuable.

Filing a multi-class application

The filing fee for a multi-class trademark application is ₹4,500 per class for small entities (which includes MSMEs). Filing all four classes costs ₹18,000 in government fees. With a trademark attorney, total cost is typically ₹25,000–40,000. The trademark, once registered, protects your brand for 10 years and is renewable indefinitely. For a company building a long-term brand identity across multiple sectors, this is one of the best investments you can make in the first year.
