Trademark Class 37: Construction and repair — What It Covers, With a Live Count
Short answer
Trademark class 37 covers building construction, repair, installation services, maintenance, cleaning, and vehicle servicing. It is a services class, and as of September 14, 2026 it holds 70,290 live US marks, 1.5% of the register, ranking 25 of 45 by size. A registration in class 37 protects the name only for these services; the same name can be, and often is, registered by an unrelated business in another class.
Class 37 is a mid-sized class, with 70,290 live marks out of 4,796,936 across all 45 classes. A live mark is one that is registered or pending; the count is computed from USPTO bulk data by each mark's primary class and refreshed daily.
Class 37 is the trades. Anything built, installed, repaired, or cleaned is here. A plumber is 37; the pipes are 6 or 19; the plumbing design is 42. Cleaning services are 37; cleaning products are 3. Landscaping splits: laying a patio is 37, planting and lawn care is 44.
What files in class 37
| Typically in class 37 | Examples of businesses |
|---|---|
| building and construction contractors | contractors and builders |
| plumbing, electrical, and HVAC installation | trades businesses |
| home repair and handyman services | home services companies |
| vehicle repair and car washes | auto repair shops |
| cleaning and janitorial services | cleaning companies |
| painting and decorating | repair franchises |
| landscaping construction (hardscape) | |
| phone and computer repair | |
| pest control services |
The USPTO's ID Manual lists the accepted descriptions for class 37. Choosing one of them keeps the filing fee at $350 per class; a custom description costs $550. See what a trademark costs.
What is not in class 37
| Looks like class 37, but is | Class |
|---|---|
| the materials installed | 19 |
| architecture and engineering design | 42 |
| landscaping and lawn care as horticulture | 44 |
| pest control products | 5 |
| real estate development | 36 |
The class follows the product, not the industry. A business in this field will often need one of the classes above as well as class 37; the second class is a second filing fee, and a registration in one does not cover the other.
Coordinated classes
The USPTO searches class 37 together with these classes when it examines an application, because confusion between them is common. A live mark in a coordinated class can block a class 37 application, and a class 37 mark can block one of these.
A near match in a coordinated class is worth reading closely. A near match anywhere else on the register is usually not. See is my name trademarked for how to read one.
How crowded class 37 is
| Live marks in class 37 | 70,290 |
| Share of the 45-class register | 1.5% |
| Rank by size | 25 of 45 |
| As of | September 14, 2026 |
A smaller class means fewer near matches, and a name that is clear here tends to stay clear. It is still worth searching the coordinated classes, since that is where a conflict for a class 37 mark most often comes from.
Before you file in class 37
- Confirm the services are actually class 37 against the USPTO ID Manual, not against the industry the business is in.
- Check the neighbouring classes in the table above for anything the business also sells or does.
- Search the name on Silvol and read every live match by class: class 37 and its coordinated classes matter; others usually do not.
- Budget per class. Each class is $350 to file and $650 every ten years to maintain.
