Consolidated Glossary of USPC Terms

A new Consolidated Glossary of U.S. Patent Classification Terms is now available on the USPTO patent classification website. The glossary consists of a comprehensive list of terms taken from the classification definitions of the USPC. Terms are listed in alphabetical order and grouped by class number for easy browsing. These definitions are useful to patent searchers in that many terms found in the USPC manual have technology-specific definitions that are different from standard dictionary definitions.
