terms of_use: USPTO’s online databases are not designed or intended to be a source for bulk downloads of USPTO data when accessed through the website’s interfaces. Individuals, companies, IP addresses, or blocks of IP addresses who, in effect, deny or decrease service by generating unusually high numbers of database accesses (searches, pages, or hits), whether generated manually or in an automated fashion, may be denied access to USPTO servers without notice. Bulk data products may be separately obtained from the USPTO, either for free or at the cost of dissemination. For details, see information on Electronic Bulk Data Products:

description: The USPTO allows parties to record assignments of patents and patent applications to, as much as possible, maintain a complete history of claimed interests in a patent. The USPTO also permits recording of other documents that affect title (such as certificates of name change and mergers of businesses) or are relevant to patent ownership (such as licensing agreements, security interests, mortgages, and liens). The 2020 update to the Patent Assignment Dataset contains detailed information on 8.97 million patent assignments and other transactions recorded at the USPTO since 1970 and involving roughly 15.1 million patents and patent applications. It is derived from the recording of patent transfers by parties with the USPTO.
