assignee_type seem to always be blank
I’m not seeing the assignee_type field with the types specified in the documentation, at least with the queries I’m running
Examples
PATENT 3930319
assignees": [{"assignee_sequence": "0","assignee_last_name": null,"assignee_organization": "Commonwealth Scientific & Industrial Research Organization","assignee_type": ""}],
PATENT 3930325
"assignees": [{"assignee_sequence": "0","assignee_last_name": null,"assignee_organization": "GENERAL ELECTRIC COMPANY","assignee_type": ""}],
