Current CPC in pre-grant data
I find some potential data errors in current CPC classifications for pre-grant data. Some CPCs of pre-grant applications are not updated to the current version in the cpc_current data file. For example, the patent application with application no. 10600922 has CPC classes of Y02T50/12 & Y02T50/166 but in the cpc_current data file for granted patents, it is Y02T50/10 (patent no. 7048505). They refer to the same patent application/grant and are supposed to have the same CPC classes. Could you please help look into this issue? Thanks a lot.
