As announced at the Patent Statistics conference in Vienna 2009, PATSTAT should get an update by getting European Classification scheme (ECLA).
Recently Geert Boedt , from patstat helpdesk, announced in patstat forum this change will take palce in april 2010.
The way it will happen is through table TLS217_APPLN_I_CLS (contining previously national classifications like for MX, US...) to TLS217_APPLN_ECLA.
Four schemes are planned:
- EC - known as ECLA, the European Classification scheme.
- ICO- In Computer Only - an internal scheme used by the EPO for classifications which are planned for moving into ECLA at some stage
- IDT - Indeling der Techniek , an old Dutch Patent Classification scheme.
- ECNO - ECLA symbols which have been allocated to a document by a patent examiner who does not work for the EPO.
