U.S. patents relying on federal funding plateaued at 30% in 2011 and is currently around 28%. The absolute number of patents dependent on federally supported research nearly doubled from 22,647 in 2008 to 45,220 in 2017.
“…Here, we consider every U.S. patent assigned to U.S. inventors since 1926, and show thatthe proportion of patents relying on federally funded science has outstripped the overall increase in patenting, plateauing since a high of 30.0% in 2011(see the first figure). Despite this plateau,the absolute number of patents that rely on federally supported research has almost doubled recently, from 22,647 in 2008 to 45,220 in 2017. We count reliance when a patent is owned by the government, acknowledges government support, or directly cites a patent or science paper that acknowledgessupport….Federal support
for U.S. invention gets routed through a variety of agencies. In 2017, for example, the Department of Defense (including the armed services) supported 6.2% of the total of U.S. inventions, HHS 5.4%,Department of Energy 3.9%, National Science Foundation 2.9%, NASA 1.0%,and Department of Agriculture 0.50% (others 5.5% and unspecified 2.5%; see SM for illustrations of R&D investment and patenting by agency and by technology class)….Large, small, and micro firms all draw upon government research, as observed in patent-renewal data. Startups also depend heavily on government research, as 34.6% of the 121,765 patents assigned to venture-backed companies from 1976 to 2016 cited federally supported research; by comparison, for all corporate patents during the same time period, only 21.7% rely on federally supported research. The higher reliance of startups on government supported research may be explained by resource constraints, which inhibit internal R&D expenditure in young ventures and encourage identification and external licensing of promising technologies. It also illustrates the intended consequence of the Bayh-Dole Act and an important path of commercialization for federal science and technology research….The average percentage of prior art citations within each patent that are supported by federal research fell from a high of 15.8% in 2003 to 9.9% in 2017. By contrast, citation of scientific papers that are supported by federal research reached a historical high of 10.7% in 2017, up from 6.9% in 2004 (see SM)….”
