INPADOC Database on STN® - The New Cooperative Patent Classification Is Now Available
The Cooperative Patent Classification (CPC) is a new patent classification system jointly developed and maintained by the European Patent Office (EPO) and the U.S. Patent and Trademark Office (USPTO). This bilateral classification system will enter into force on the first of January 2013 and will replace the European patent classifications, ECLA and ICO, and also the U.S. national patent classification, USPC.
The CPC is an IPC-based classification system with about 250,000 subdivisions comprising the former ECLA and ICO codes, plus an expanded scheme for business methods (G06Q) and special collections from the U.S. patent classification.
From week 47/2012 onwards, CPC data will be available for new and updated records of the INPADOC databases. Users have full access to all details of the CPC data including CPC codes and attributes. A CPC thesaurus feature supports classification searching, helping users to identify relevant codes and searching the hierarchy of the codes.
