In some previous posts I made available some code about ISI-OST-INPI IPC reclassification in 30 classes.
Recently, in order to have a better balance of the number of patents contained in the different classes, it has been proposed a 35 classes reclassification.
At this link can be consulted the ufficial document from Ulric Schmoch, published from WIPO.
So I made, in order to give am easier format, an excel file containing descriptions in one sheet and IPCs (in the second sheet); the file can be downloaded from this link.
Care the reclassifications sheet contains a colums IPCNOT showing that, if the patent contains such IPCs should be discarded from the class, regardless other IPCs should belong to it.
Differently from ISI-OST-INPI, this reclassification should be run on ALL IPCs (main and secundary).
As the author correctly adresses, this will lead to a 20% of patents belonging to 2 or more classes and for such cases only the main IPC (if available) should be used for reclassifications.
Have fun!!!
