Patent assignee table and patent inventor table mismatch with application

I tried to link the patent_assignee and patent_inventor table with application. I find two problems.

1. In the patent_assignee and patent_inventor table, there are a lot of observations with patent id == . I am wondering that if you don't know that patent id, how can you know their assignee and inventor.

2. When I merge the patent_assignee table and patent_inventor table with application table using patent_id, a lot of patent id in patent_assignee table and patent_inventor table can not be found in application table. Could you tell me why? For example, patent_id
10791665
10791666
10791667
10791671

in patent assignee table can not be found in application table.

By the way, can you please tell me if I have a list of assignee name, how can I find out all the patents filed by them?

Regards,
Hengyi

Seeing similar things

Data in claims seems more up to date than the patent file.
