# Trademark class 37: Construction & repair

Source: https://joinopenfile.com/trademark/classes/37
Index: https://joinopenfile.com/llms.txt

Businesses that sell construction, plumbing, roofing, contractor and similar often file in class 37.

## Sample wording

Building construction services; plumbing services; roofing services; cleaning of residential houses

Wording from the USPTO's list avoids its $200 per class surcharge for custom text. Your application should only list what you actually sell or plan to sell.

## Class 37 questions

How much does it cost to file in class 37?

The USPTO charges $350 per class. With us it's $200 on top, so $550 for one class.

Can I file in more than one class?

Yes, if you sell things in more than one. Each extra class adds $350 in USPTO fees.

What if I pick the wrong class?

You can't move a filing to a class that widens what it covers, so getting it right before you file matters. Our form suggests classes from what you sell, and the attorney reviews them.
