Question on patent_assignee

In the case of patents whose assignee changes over time, potentially even prior to the patent being granted, how is the patent assignee (assignee_id) listed in the patent_assignee dataset defined?

Is it the patent's first assignee (even if that assignment took place during the patent's examination phase, prior to the patent being granted), the assignee at the time that the patent was granted, or something else? 

Thanks!

Patent assignee at issue

Hello, good question! Pre-grant and granted data in the PatentsView system has the assignee(s) named at issue. So the assignees on the published application are the assignees on the granted patent, and at this time, PatentsView does not collect or carry reassignment data for if additional changes to the assignee occur after the patent is granted. Let us know if you have additional questions as you're working with patent data!

Best,
