First Reclassification of IPC Codes now completed in INPADOC

27. May 2006

The first and major part of the reclassified International Patent Classification (IPC) data from the Master Classification Database (MCD) of the European Patent Office (EPO) has been implemented in the INPADOC database on STN. The EPO has announced a delivery of further reclassified data for later this year. The current implementation has assigned new or reclassified IPC8 codes to about 94% of the 34,7 million Inpadoc records. Rolled-up Core codes - the corresponding Core level codes from Advanced level codes - are included.

These Rolled-up Core codes facilitate the retrieval of patent records issued across all patent offices, regardless of which level of IPC codes the offices apply. They are marked with an asterisk (*) in the DISPLAY. More information about the IPC reform can be found in
