Classification Definitions

This takes us to the Classification Definitions. This is where the working definitions for all utility subclasses of the U.S. Patent Classification System are located. Toggle between Show Definition View and Show Schedule View for more information.

Occasionally, you will find suggestions for other subclasses to consider. These suggestions can also helpful if you have been looking in the wrong classification. It is often helpful to look at the definition of the class as a whole, at the top of the page.
