The United States Patent and Trademark Office’s (USPTO) Office of the Chief Economist released 2020 updates for two research datasets, the Patent Assignment Dataset and the Patent Examination Research Dataset (PatEx).
The Patent Assignment Dataset now contains detailed information on 8.97 million patent assignments and other transactions recorded at the USPTO since 1970—involving roughly 15.1 million patents and patent applications.
The Patent Examination Research Dataset (PatEx) now contains detailed information on over 16.5 million United States patent and Patent Cooperation Treaty (PCT) applications filed with the USPTO through April 2021. The dataset includes information on patent application characteristics, examination and continuation histories, and more.
