Trademark Class 37: Construction, Installation & Repair Services
Class 37 covers building construction, installation, maintenance, and repair services. Here is what it includes, what it excludes, and how to word it.
What is Trademark Class 37?
Class 37 is a services class covering building construction, installation services, and repair and maintenance. It includes construction and civil-engineering work, installation of equipment, and the repair, servicing, and maintenance of buildings, vehicles, and equipment.
The theme is building, installing, and repairing physical things. It is distinct from the building materials themselves (Class 19 or 6) and from design or engineering services (Class 42). This page is part of our full guide to all 45 trademark classes, and to how protection works across jurisdictions in our overview of trademark law and protection.
Is Class 37 actually your class?
Work out whether your product or service genuinely sits in Class 37 before you file, because a wrong class protects the wrong thing.
Class 37 is likely your class if you provide construction, installation, or repair services
Construction and building firms, installation contractors, maintenance and repair businesses, vehicle-repair and servicing providers, and equipment-servicing companies. If your service involves building, installing, maintaining, or repairing physical things, Class 37 is very likely your class. Our trademark class search helps you check which classes fit before you file.
What Class 37 does NOT cover.
The most common Class 37 mistakes come from classifying by the wrong feature. These closely related items sit elsewhere:
Building materials are Class 19 or 6
The physical materials are Class 19 (non-metal) or Class 6 (metal). Class 37 is the construction service.
Design and engineering are Class 42
Architectural and engineering design is Class 42; the physical building work is Class 37.
Examples of properly-worded Class 37 goods and services.
The Registry expects specific, standardised descriptions, not vague terms. Here are examples of clear, acceptable Class 37 wording:
| Instead of (vague) | Use (standardised) |
|---|---|
| “Construction” | “Building construction” · “Construction services” |
| “Repair” | “Repair services” · “Maintenance and repair of [specify]” |
| “Installation” | “Installation services” · “Installation of [specify]” |
Each entry is specific and standardised. These are illustrative examples of acceptable phrasing, not legal advice for your filing; your exact wording should be drawn from the current NICE Classification and tailored to what your business actually does. Wording is a common cause of objections whether you file in India, the United States, Argentina, or elsewhere. For filing across several countries at once, see our global registration guide.
Frequently asked questions
What does trademark Class 37 cover?
Class 37 covers building construction, installation services, and repair and maintenance. It includes construction and civil-engineering work, installation of equipment, and the repair, servicing, and maintenance of buildings, vehicles, and equipment. The building materials themselves are Class 19 or Class 6, and design or engineering services are Class 42.
Who should register a trademark in Class 37?
Construction and building firms, installation contractors, maintenance and repair businesses, vehicle-repair and servicing providers, and equipment-servicing companies. If your service involves building, installing, maintaining, or repairing physical things, Class 37 is likely your class.
What is the difference between Class 37 and Class 42?
Class 37 covers the physical building and repair work, actually constructing, installing, or repairing something. Class 42 covers design and engineering services, such as architectural design and engineering consultancy. So designing a building is Class 42, but constructing it is Class 37. A firm that both designs and builds may need both.
Are repair services in Class 37?
Yes. The repair, servicing, and maintenance of buildings, vehicles, machinery, and equipment are classified in Class 37. This includes vehicle repair, appliance servicing, and building maintenance. The class covers the physical act of repair and upkeep, as opposed to selling the parts, which fall in their own goods classes.
How should I word my Class 37 services?
Use specific, standardised terms such as building construction, installation services, or repair and maintenance of specified items, rather than vague words like building work. Draw wording from the current NICE Classification and tailor it to your services to reduce objection risk.
