The Process Innovation Patent Dataset classifies claims of all utility patents awarded by the U.S. Patent and Trademark Office (USPTO) since 1976 into process and non-process. Standardized legalistic language used in the drafting of patent claims allows to accurately distinguish process from non-process claims using textual analysis techniques. A process innovation typically describes a new way to produce an existing good, while a non-process innovation typically describes a new good that did not exist before.
Based on this data, in Bena and Simintzi (2019) and Bena, Ortiz-Molina, and Simintzi (2020), we create measures of process and non-process innovation at firm-year level to explore the link between labor markets and process innovation. A detailed description of the dataset, including its key features and how it was constructed, can be found in these papers.
