  This paper examines the citation impact of papers published in
scientific-scholarly journals upon patentable technology, as reflected in
examiner- or inventor-given references in granted patents. It analyses data
created by SCImago Research Group, linking PATSTAT's scientific non-patent
references (SNPRs) to source documents indexed in Scopus. The frequency of
patent citations to journal papers is calculated per discipline, year,
institutional sector, journal subject category, and for "top" journals.
PATSTAT/Scopus-based statistics are compared to those derived from Web of
Science/USPTO linkage. A detailed assessment is presented of the technological
impact of research publications in social sciences and humanities (SSH).
Several subject fields perform well in terms of the number of citations from
patents, especially Library & Information Science, Language & Linguistics,
Education, and Law, but many of the most cited journals find themselves in the
interface between SSH and biomedical or natural sciences. Analyses of the
titles of citing patents and cited papers are presented that shed light upon
the cognitive content of patent citations. It is proposed to develop more
advanced indicators of citation impact of papers upon patents, and ways to
combine citation counts with citation content and context analysis.
