Addresses quality checks in PATSTAT2017b by application authority

After uploading new PATSTAT version I ran a check on coverage of addresses and at what level, also comparing with 2017a version;
I show here two tables for inventors and applicants, for authorities with more than 100K addresses.
So, for example column street ratio means the percentage of person ids in that application authority that have a street level address.
SRchg means the change betwwen 2017b and 2017a at street level coverage.
You'll note a big difference in coverage for EP between inventors and applciants; that is due to PCT patents.


For inventors.
