This report describes the results of an analysis tracing the technological influence of advanced combustion research funded by the U.S. Department of Energy (DOE)’s Vehicle Technologies Office (VTO) and its precursor programs, as well as advanced combustion research funded by other offices in DOE. A total of 442 advanced combustion patents are confirmed to be associated with VTO funding (337 U.S. patents, 44 EPO patents, and 61 WIPO patents). Advanced combustion research funded by VTO, and by DOE in general, has had a significant influence on subsequent developments, especially within advanced combustion technology. This influence can be seen on innovations associated with the leading advanced combustion companies, with many of their patents linked extensively via citations to earlier advanced combustion patents associated with VTO and DOE funding.
