This report describes the results of an analysis tracing the technological influence of solid state lighting (SSL) research funded by the U.S. Department of Energy (DOE)’s Building Technologies Office (BTO) and its precursor programs, as well as SSL research funded by other offices in DOE. A total of 439 SSL patents are confirmed to be associated with BTO funding (242 U.S. patents, 91 EPO patents, and 106 WIPO patents). Solid state lighting research funded by BTO, and by DOE in general, has had a significant influence on subsequent developments, both within and beyond SSL technology. This influence can be seen on innovations associated with the leading SSL companies. It can also be traced on innovations across a range of other technologies, including semiconductors, electronics and advanced materials.
