This report describes the results of an analysis tracing the technological influence of bioenergy conversion research funded by the U.S. Department of Energy (DOE)’s Bioenergy Technologies Office (BETO) and its precursor programs, as well as bioenergy conversion research funded by other offices in DOE. A total of 974 bioenergy conversion patents are confirmed to be associated with BETO funding (515 U.S. patents, 241 EPO patents, and 218 WIPO patents). Bioenergy conversion research funded by BETO, and by DOE in general, has had a significant influence on subsequent developments, both within and beyond bioenergy conversion technology. This influence can be seen on innovations associated with the leading bioenergy conversion organizations. It can also be traced to innovations in other technologies, notably chemical production.
