Research outline and main results
The project aims to verify the exis­tence of a link between the generators of highly cited publications and important inven­tions (defined as highly cited patents), where by link it is meant a tie or a trail in a social network connecting the inventor(s) of a highly cited patent and the author(s) of the highly cited publication (scientist). These social ties or trails can be inferred by the exis­tence of linkages between highly cited patents and publi­cations by applicants, inventors, authors, and location of the institutional affiliation of the author(s) per technology field. However, the extent to which the proposed linkages can unambigously identify a social tie/trail varies greatly; and in a few cases, even the identifi­cation of a connection between two nodes in a social network tells us little on the quality of the information transmitted between two nodes.
The core part of the study will be a sophisticated dynamic network analysis in order to establish whether and which linkages, as defined above, exist.
This analysis will cover:

  • 5 technology fields
  • the period from 1990 to the most recent available year
  • the top 20 inventors of highly cited patents, of which at least 10 have to originate from an ERA country for each technology field
  • the top 20 authors of highly cited NPL (non- patent literature), of which at least 10 have to originate from an ERA country for each technology field

To this end, the study will develop an integrated data set, based on EPO and USPO patent data, on one hand, and scientific papers cited in patent documents on the other.
