Trademark Class 37: Construction, Repair & Installation Services

Choosing the right trademark class is essential for proper brand protection. When you apply for a trademark under the wrong class, it may lead to rejection or limited legal coverage. Trademark Class 37 is one of the service-based classes and is particularly important for businesses in the construction and repair sectors.

Let’s dive into what Class 37 includes—and what it doesn’t.

What is Trademark Class 37?

Class 37 primarily covers:

• Building construction

• Repair services

• Installation services

These include services provided by builders, electricians, plumbers, painters, roofers, and carpenters, among others. Whether it’s residential, commercial, or industrial projects, if your service involves the physical alteration or maintenance of a structure or machinery, it likely belongs in Class 37.

Examples of Services in Class 37

Some common services under this class include:

• Construction of houses, offices, and commercial buildings

• Road construction and civil engineering works

• Plumbing and electrical installations

• HVAC system installation and maintenance

• Pest control services

• Car repair and maintenance

• Elevator or escalator installation

• Painting and decorating of interiors or exteriors

Even services like cleaning of buildings, industrial equipment maintenance, and pool installation are part of this class.

What is NOT Included in Class 37?

To ensure clarity, Class 37 does not cover:

• Architectural or engineering design services (Class 42)

• Retail or wholesale of construction materials (Class 35)

• Construction project financing (Class 36)

• Consulting unrelated to physical installation or repair

Always consider related classes if your services span multiple categories. Filing in the correct combination of classes ensures broader protection.

Why Correct Classification Matters

Registering in the wrong class can delay approval or weaken your legal standing. Accurate classification:

• Prevents trademark objections

• Protects your service from copycats

• Supports business growth and franchising

• Improves investor and customer trust

Moreover, if your business offers multiple services, you may need to file under several trademark classes.

Filing Tips for Class 37

To make your application stronger:

• Be specific about the nature of your services (e.g., “commercial HVAC installation” vs. “installation services”)

• Conduct a trademark search to avoid existing conflicts

• If you’re unsure, consult a trademark professional to guide your classification

Filing with the right wording and class the first time saves both time and legal hassle.

Trademark Class 37 is crucial for anyone offering services that involve building, repairing, maintaining, or installing physical structures or systems. If your business falls into this category, ensure your trademark is properly filed to secure long-term protection.
