This report describes the results of an analysis tracing the technological influence of bioenergy feedstock research funded by the U.S. Department of Energy (DOE)’s Bioenergy Technologies Office (BETO) and its precursor programs, as well as bioenergy feedstock research funded by other offices in DOE. 146 feedstock patents are confirmed to be associated with BETO funding (87 U.S. patents, 25 EPO patents, and 34 WIPO patents). Bioenergy feedstock research funded by BETO, and by DOE in general, has had a significant influence on subsequent developments, both within and beyond feedstock technology. This influence can be seen upon innovations associated with the leading feedstock organizations. It can also be traced in other technologies, notably biofuel production, chemical manufacturing, and waste treatment.
