Classification tools at the EPO

Abstract
Describes the European Classification System (ECLA) used by search examiners at the General Directorate 1 (DG 1) of the European Patent Office in The Hague, Netherlands, for classifying patent applications for publication, new patent documents and non-patent literature for addition to the systematic search documentation. ECLA is an internal classification tool developed on the basis of the International Patent Classification (IPC) but with further subdivisions and better adaptation to the different technical fields. In order to overcome the limitations of a classification system, secondary systems are also in use or under development. One such system is the ICO (In Computer Only) system which offers online only light indexing schenmes for the identification of additional information contained in patent documents
