European Classification

The European Classification (ECLA) is a patent classification system maintained by the European Patent Office (EPO). The ECLA classification system contains 134 000 subdivisions. It is mainly an extension of the International Patent Classification system, but sometimes modifies its titles and rules. ECLA is used in connection with the indexing system ICO, which serves to identify additional information and aspects that are not covered by the ECLA schemes. [1]
