Trademark Class 37 for Protecting Construction, Repair & Installation Service Brands
If you offer services related to construction, building repair, installation, or maintenance, your brand belongs under Trademark Class 37. This class plays a vital role in protecting businesses that shape physical infrastructure—be it residential, commercial, or industrial.
From civil engineering firms and plumbing services to elevator installation and building maintenance providers, Class 37 ensures protection for your hands-on service brand in a competitive, project-driven industry.
Let’s explore what falls under Trademark Class 37, what doesn’t, and how to secure your service identity by starting your online trademark registration the right way today.
Understanding Trademark Classification in India
Trademark registration in India is governed by the Trade Marks Act, 1999, and uses the globally accepted Nice Classification system. This system categorizes goods and services into 45 trademark classes, with Classes 1 to 34 for goods and Classes 35 to 45 for services.
Each class defines a distinct category of goods or services, helping ensure that trademarks are protected within their specific business domain.
Trademark Class 37 is reserved for businesses offering services related to construction, installation, repair, and maintenance. If your business builds, installs, maintains, or repairs physical structures, equipment, or utilities, this is likely your correct class.
What Services Can You Trademark Under Class 37?
Class 37 is comprehensive and includes a wide variety of hands-on, operational services related to the physical construction, repair, and installation of buildings, machines, and infrastructure. If your business works on-site—building structures or fixing them—your offerings likely fall under this category.
Here’s what you can trademark under Class 37
- Construction services – Building residential, commercial, industrial, or public structures; civil engineering and site preparation.
- Repair services – General building repairs, furniture repairs, restoration of historic structures, and repair of tools, vehicles, or electrical items.
- Installation services – Installation of elevators, air conditioning systems, solar panels, plumbing systems, electrical wiring, and other machinery or utility systems.
- Maintenance services – Ongoing maintenance of buildings, industrial plants, or utility systems, including HVAC, fire safety systems, and security alarms.
- Renovation and refurbishment – Interior remodeling, retrofitting, and space enhancement services.
- Cleaning services (industrial or construction-related) – Post-construction cleaning, exterior building cleaning, and site decontamination.
These services are commonly offered by contractors, repair technicians, infrastructure companies, facility managers, and skilled tradespeople.

What Is Not Included in Trademark Class 37?
While Class 37 protects many construction and repair-related services, some commonly confused services fall outside its scope due to their different functions or industry classifications.
Here’s what is not included—and where those services should be classified instead:
- Architectural design and planning are not part of this class. These services involve conceptual and aesthetic planning, not physical execution. They fall under the trademark class for architectural services (Class 42).
- Real estate brokerage and property sales are not construction activities. These fall under the trademark class for real estate services (Class 36), as they involve financial and transactional services rather than physical work.
- Cleaning services for household use, like laundry or maid services, belong to the trademark class for personal and domestic services (Class 45), since they are consumer-focused and not related to industrial or site cleaning.
- Software installation and IT setup do not fall under this class, as they pertain to digital environments. These should be filed under the trademark class for IT and technology services (Class 42).
- Manufacturing of construction materials like cement, bricks, or prefabricated structures is not included. These are considered goods, not services, and fall under the trademark class for building materials (Class 19).
Determining the exact trademark class for your services can be tricky, especially when items overlap in function. If you’re unsure where your goods fit, use our Trademark Class Search Tool to find the right match and avoid rejection or delays.
Intellectual Properties You Should Trademark Under Class 37
In the highly competitive construction and repair industry, protecting your brand assets is vital to ensure credibility, legal safety, and long-term recognition. Whether you’re a general contractor, installation specialist, or civil infrastructure provider, securing your identity under Trademark Class 37 helps prevent brand misuse.
Here’s what you should consider trademarking under this class
- Company or Contractor Name – Builders like Larsen & Toubro Construction or Shapoorji Pallonji use distinct brand names to gain trust and visibility.
- Service Brand Name – Specialized offerings like Urban Company Home Services, Livspace Renovation, or Asian Paints Safe Painting Service are registered as standalone service brands and can be trademarked under the construction and repair category.
- Project Series or Commercial Programs – If you offer branded initiatives like GreenBuild Projects or SmartSpace Installations, these proprietary programs can be registered.
- Logo and Design Elements – Logos used on uniforms, vehicles, helmets, and signage (e.g., Bharat Infratech’s crane logo) are ideal for trademark protection.
- Taglines and Slogans – Phrases like “Built on Trust” (L&T Construction), “Building Beyond Walls” or “Strength You Can See” not only differentiate your brand but can also be trademarked.
By protecting your intellectual properties under Class 37, you strengthen your market presence and secure exclusive rights to your construction service identity.

Frequently Asked Questions
Can construction services be registered under Class 37?
Yes. Construction, repair, installation, and maintenance services are covered under Trademark Class 37.
I run a repair and maintenance business—should I register my service names?
Absolutely. Unique names for your repair programs or installation services can be trademarked under Class 37 to protect your brand identity.
Are building materials covered under Class 37?
No. Physical goods like building materials fall under different trademark classes (such as Class 19 for non-metallic building materials). Class 37 is specifically for services related to construction and repairs.
What if I offer both construction services and real estate brokerage?
You’ll need to register under multiple classes—Class 37 for construction and repair services and Class 36 for real estate services.
How can I check if a similar trademark already exists in Class 37?
You can perform a trademark class 37 search to identify existing marks and avoid potential conflicts.
Can I register a trademark for my construction business before starting operations?
Yes, you can file based on intended use. You’ll need to show your bona fide intent to use the mark commercially.
What happens if I choose the wrong class?
If you choose the wrong trademark class, your application may still get processed, but your trademark won’t be legally protected for the relevant services. This means others could legally use a similar mark in that correct class, and you wouldn’t have grounds to stop them. Moreover, trademark fees are non-refundable, so you’d have to file a new application in the correct class and pay the fees again.
How long does registering a trademark take?
Trademark registration in India typically takes 6 months to 2 years, depending on any objections or third-party opposition. For a detailed overview of the process, read our complete guide on trademark registration process in India.
How long is a trademark valid under Class 37, and when should I renew it?
In India, a registered trademark is valid for 10 years. You must renew it every 10 years—either within 6 months before or after expiry—to maintain your rights.
