The latest update to the United States Patent and Trademark Office (USPTO) Patent Assignment Dataset, consisting of full data files from 1970 to 2019, is now available to the public for free download. The dataset is an organized relational database of patent assignment and other related transactions, such as name changes, business mergers, licensing agreements, security interests, and liens. The USPTO first published the dataset in 2014 and updates it annually. We derive this information from parties’ recording of their patent transfers with the USPTO, thus creating a complete history of claimed interests in a patent. With this addition, the dataset now contains detailed information on 8.6 million patent assignments and other transactions since 1970, involving roughly 14.9 million patents and patent applications.
