Product 14.8

Cooperative Patent Classification (CPC) in XML


The CPC is a joint EPO-USPTO project aimed at developing a common classification scheme for technical documents, in particular patent publications, which will be used by both offices in the patent granting process. Cooperative Patent Classification (CPC) scheme and some finalised CPC definitions were officially launched on 1 January 2013.

The CPC scheme is initially based on the European Classification (ECLA), keeping all its properties.

In addition to the former ECLA groups, the CPC scheme also includes:

  • all former EPO ICO (indexing) codes,
  • the vast majority of former EPO “keywords(KW)”, which were converted to valid ECLA/ICO symbols before becoming CPC symbols,
  • some more entries originating from the US patent classification, e.g. further subdivisions for “Business Methods”,
  • USPC cross-reference art collections [XRACs] and digests.
