Patent Assignment Dataset

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 2016 update to the Patent Assignment Dataset contains detailed information on 7.2 million patent assignments and other transactions recorded at the USPTO since 1970 and involving roughly 12.2 million patents and patent applications. It is derived from the recording of patent transfers by parties with the USPTO.

A document describing these data is available here: “The USPTO Patent Assignment Dataset: Descriptions and Analysis.” Users are requested to cite this documentation when using these data. It is also available as: Marco, Alan C., Graham, Stuart J.H., Myers, Amanda F., D'Agostino, Paul A and Apple, Kirsten, The USPTO Patent Assignment Dataset: Descriptions and Analysis (July 27, 2015).
