Trade mark class 37: building, repairs and cleaning
In everyday words: Building, construction, installation, repairs, maintenance, cleaning, mining. Class 37 is one of the services classes (35 to 45).
What class 37 covers
The summary above is ours, written to help people find the right class. It isn’t IP Australia’s official class heading, and it doesn’t list everything in the class. For the exact goods and services, search IP Australia’s trade mark pick list.
A trade mark is registered for the goods or services in its application, so a registration in class 37 doesn’t cover other classes. Our guide to picking your classes explains how to choose.

How these figures are counted
Applications are counted by filing date from IP Australia’s data, as CopyCatcher held it on 6 October 2026, for complete months only. An application naming several classes counts in each of them. No applicant is named. Where our data comes from
