Science-Metrix was commissioned by SRI International, on behalf of the National Science Foundation’s Center for Science and Engineering Statistics, to develop measures and indicators of research and innovation activity for inclusion in the Science and Engineering Indicators (SEI) 2026. These measures were based on bibliometric and patent data. The technical documentation details the steps taken to implement the databases, clean and standardize the data, and produce statistics on technometric data, including not only US utility patents from the United States Patent and Trademark Office, but also trademarks from the same office, as well as granted patent families covering patents from dozens of patent authorities. 

Note: This work was funded by the National Science Foundation’s (NSF) National Center for Science and Engineering Statistics. Any opinions, findings, conclusions or recommendations expressed in this report do not necessarily reflect the views of NCSES or the NSF. The analysis for this research was conducted by SRI International on behalf of NSF’s NCSES under NCSES Technical and Analytical Support Services task orders 49100421D0019-49100423F0236.
