ECLA-European Patent Classification

The European Patent Classification ECLA, is a refinement of the International Patent Classification IPC. It has been replaced by the Cooperative Patent Classification CPC on 1 January 2013.

Previously the EPO used the ECLA patent classification system and the US used their own classification system.

In order to harmonize the two systems the CPC (Cooperative patent classification) system was created.
