- Location ID added to patent_assignee and patent_inventor
- Previously to identify the location of a patent by the way of the assignee, patent_assignee needed to be joined with location_assignee and then with the location table. A similar join was needed for the patent inventor. To reduce the complexity, patent_assignee and patent_inventor tables will carry an additional field: location_id. This field will map to the id field from the location table. This makes the data in location_assignee and location_inventor redundant. Future releases will not carry these two tables.
