Way Better Patents has extracted all of the domain specific terms of art that appear within the US Patent Classification System (USPC). These definitions reflect how a particular term is defined within a specific USPC class and how it applies to the patents and patent applications that are classified in that class. The definitions include a link to the Class Definition at USPTO if you'd like to explore more details about what is classified in a particular class or look at patents and patent applications assigned to the class. This glossary lets you compare how a particular word is defined in different classes. There are three different definitions for the word "Active" — one that pertains to pharmacology and biology; one that relates to plant growth; and a third that deals with an "active database." There are five definitions of "Acylic", three for "Address Data"; five for "Alkali Metals", and we aren't even out of the A's yet.

The Cooperative Patent Classification System Is Coming
USPTO and their colleagues at the European Patent Office (EPO) are moving to a new the Cooperative Patent Classification System (CPC). As the Cooperative Patent Classification system evolves, we will add any new or different definitions that appear in the CPC to assist you in making the transition to the new classification system and seeing if there are differences between the USPC and the CPC terms of art that warrant thinking about inventions in a new way to look for and find prior art.

A Caveat
The Definitions were taken verbatim from the USPC Class Definitions. We are in the process of integrating the images that help explain the definitions. They should be available shortly. If you would like to see the rest of the information about a particular class, just use the link next to the definition an it will take you to USPTO USPC digital repository.
