Joint Patents / Multiple Assignees

Hi all, 

I'm working on a Master's thesis in which I want to investigate the correlation between joint patents and patent quality. I am using the Query Builder to collect data for my analysis.

There appears to be only one "assignee_organization" column in the data output. How would multiple assignees on a joint patent be displayed in the output? 

Thank you in advance!

cross product

Hi,

The query builder will give you multiple rows if you request a column that has more than one value.   I just tried a query for pantent_number equal to 10694123 requesting patent number, inventor first name, inventor last name, assignee organization but I haven't received the results yet.  It has 5 inventors and 2 assignees.  I think it'll return a 10 row csv (a row for each of the combinations of inventor and assignee).  The preview showed 5 rows so I'm not positive it'll send the full cross product. 

I think the python wrapper does the same cross product thing but when I ran it it said it returned no results.   Something must be up with the api.
