Dear Patentsview Team,
I'm working on assignee_disambiguated data but found that there's mismatch in assignee country indicated by assignee_type and assignee_country variables. For example: US3940599 was assigned to EMI, LLC which is a firm in England, but the assignee_type is 2 which means that this is a US firm. In the dataset as a whole, if I set the filter assignee_type==2 & assignee_disambig_country=="" (i.e. assignee_type is US firm but the assignee country is missing), the observations takes up 39,973/20,428,659. I was wondering what's going on here and how is the two variables: assignee_type and assignee_disambig_country determined in your data construction process. Thank you! Really appreciate it!
