Now I understand that searching for patents based on applicant and inventor country of origin is difficult because information is not always available due to fields being left blank. I am also aware that not all intellectual property offices provide the same quality and completeness of data.
Seeing as this topic has reappeared over the years, I was wondering if progress has been made in this area. More specifically, is there an approach to solving this issue that is recognized as more appropriate than others and are there any studies that have used this approach?
Any help is much appreciated.
Thank you

Re: Searching for Patents Based on Applicant Country of Orig
These guys have developed an algorithm to replenish missing data:

The general approach is to use patent families, and use the country of patent office if nothing else works.
