Abstract
Purpose –The purpose of this study is to analyse and explore the characteristics of patent–paper pairs
(PPPs) in the eld of fuel cells.
Design/methodology/approach –The authors used bibliometric analysis to analyse the bibliometric
records of PPPs identied from 20,758 papers and 8,112 utility patents between 1991 and 2010.
Findings –The ndings show that the percentages of papers and patents constituting PPPs were low,
but an increasing trend was identied in the absolute number of PPPs. Researchers afliated with
research institutions were the primary contributors to PPPs. Countries with the most papers and patents
had the most PPPs, exploiting the advantage of dual knowledge creation. Similar growth trends were
observed in the numbers of patents approved and papers published. Patents in PPPs were typically
produced earlier than the papers in PPPs. On average, patents were applied for approximately four years
before papers were published, and patents were approved only approximately four months before papers
were published.
Research limitations/implications –While the study was limited to the PPPs in the eld of fuel cells,
PPPs analysis can be applied to numerous elds.
Originality/value –PPPs indicate the coactivity of researchers involved in publishing and patenting.
Although this coactivity has been studied, few studies have investigated PPPs. This study helps us better
understand the characteristics of papers and patents constituting PPPs, changes in the annual numbers of
papers and patents constituting PPPs, delays between papers and patents, as well as individuals, institutions
and countries producing numerous PPPs.

Introduction
The relationship between science and technology constitutes a considerable concern for
researchers because science cannot be separated from technology. Numerous researchers
have claimed that the interaction between science and technology is the key to innovation
(Bhattacharya and Meyer, 2003;Brusoni et al., 2001). An innovative idea may constitute the
foundation of a research paper, a patent or both. This means that the knowledge derived from
