The orgname (organization name) and the first and last name columns identify the patent assignee. Other than patentcountry, all other table variables apply to the organization or person. Orgname is not standardized. Certain patents have multiple assignees, resulting in repeated patent numbers. The key in this table is composite and consists of a unique combination of last and first name, orgname, and patent number.
