Hi, have you got an updated table showing the number of entries in the CPC/IPC classification systems and also the number of documents which were classified using both systems.
Many thanks.

Re: CPC / IPC
Hello Philippe,
I am not sure what statistics exactly you would like to have, but in the linked excel sheet you will find data on the allocation and / or distribution of the IPC and CPC codes. (data was extracted from PATSTAT, the SQL code to do so are included in the document.)
