<p>We compared the technological impact of five countries—the
United States, Japan, Germany, the United Kingdom, and China—using two
indicators that we developed—the Patent–Paper Citation Index (PPCI) and the
High Feature-Valued Patent–Paper Citation Index (HFPPCI)—and whose
reliabilities we validated. First, we analyzed both the scientific and
technological impacts of papers using the PPCI in combination with the
Normalized Citation Impact. Results revealed the relatively high scientific and
technological impacts of the United States in all disciplines and China’s rapid
rise of the both impacts. However, PPCI values tended to asymptotically
approach average values as the share of papers increased.Second, we analyzed the
relative citedness of papers in high-feature-valued patents in terms of patent
family size, patent–patent forward citations, and patent generality index—using
the HFPPCI. Results showed the relative citedness of each country’s papers with
high-feature-valued patents among all papers from the country. </p>
