Joint EPO-USPTO Cooperative Patent Classification (CPC) System Successfully Entered Force

As anticipated, the joint EPOUSPTO Cooperative Patent Classification (CPC) system entered into force on 1 January 2013. It has already fully replaced the EPO’s “ECLA” classification scheme.

In its newest issue, “Patent Information News”, which is published by the European Patent Office, reports about the structure of the CPC.
