Abstract
Firms operating in science-based technological fields reflect some of the complexities of the science-technology interaction. The present study attempts to investigate these interactions by analyzing patent citations, publication and patent outputs of multinational corporations (MNCs) in 'thin film' technology. In particular we explore different characteristics of knowledge production and knowledge utilization of these firms. The results indicate no correlation between intensity of research activity and patents produced by the MNCs. The relationship between scientific and technological knowledge generation as well as the linkage between science and technology appear to be firm-specific rather than dependent on a technological or industrial sector. The dispersion of journal sources for the majority of patent citations of scientific literature as well as for the majority of scientific outputs is narrow. Basic journals play an important role in patent citation as well as in addressing research of MNCs in thin-film technology.
Abstract
There is a rich literature on how science and technology are related to each other. Patent citation analysis is amongst the most frequently used to tool to track the strengths of links. In this paper we explore the relationship between patent citations and citation impact in nanoscience. Our observations indicate that patent-cited papers perform better in terms of standard bibliometric indicators than comparable publications that are not linked to technology in this way. More specifically, we found that articles cited in patents are more likely to be cited also by other papers. The share of highly cited papers is the most striking result. Instead of the average of 4% of all papers, 13.8% of the papers cited once or twice in patents fall into this category and even 23.5% of the papers more frequently cited in patents receive citation rates far above the standard. Our analyses further demonstrate the presence and the relevance of bandwagon effects driving the development of science and technology.
Abstract
This paper aims to contribute to a better understanding of patent citation analysis in general and its application to novel fields of science and technology in particular. It introduces into the subject-matter by discussing an empirical problem, the relationship of nano-publications and nano-patents as representations of nano-science and nano-technology. Drawing on a variety of sources, different interpretations of patent citations are presented. Then, the nature of patent citations is further investigated by comparing them to citations in the scientific literature. After characterizing the citation linkage as indicators of reciprocal relationships between science and technology, patent citations in nano-science and technology are analyzed in terms of interfield and organizational knowledge-flows.
Abstract
This study utilized artificial neural network (ANN) to explore the nonlinear influences of firm size, profitability, and employee productivity upon patent citations of the US pharmaceutical companies. The results showed that firm size, profitability, and employee productivity of the US pharmaceutical companies had the nonlinearly and monotonically positive influences upon their patent citations. Therefore, if US pharmaceutical companies want to enhance their innovation performance, they should pay attention on their firm size, profitability, and employee productivity.
Abstract
This paper explores the interrelationships between science and technology in the emergingarea of nano-science and technology. We track patent citation relations at the sectoraldisciplinary,the organizational, and the combined industrial/organizational levels. Then weinvestigate the geographic location and organizational affiliation of inventor/authors. Our mainfinding is that there are only a small number of citations connecting nano-patents with nanosciencepapers, while nano-science and technology appear to be relatively well connected incomparison with other fields. Further explorations suggest that nano-science and technology arestill mostly separated spheres, even though there are overlaps, as an analysis of title words shows.Another observation is that university-assigned patents seem to cite papers more frequently thanother patents.
. Source data There are two forms of patent citations. The “examiner citation,” which indicates the reason a particular patent that was requested for examination was denied by the examiner, and the “applicant citation,” which is the list of
patent citation as a trail of knowledge flow and evidence of external learning. As new entrants in the flat panel display (FPD) industry, the Taiwanese indigenous firms did not have the core technology available, and therefore, they actively engaged in
Abstract
This paper sets out to explore the patterns of technological change and knowledge spillover in the field of flat panel display (FPD) technology, along with the catching-up behavior of latecomers, through the analysis of US patents and patent citations between 1976 and 2005. Our results show that: (i) the catching-up by FPD technology latecomers began at the transition stage (1987-1996) when the dominant design became established in areas with high ‘revealed technology advantage’ (RTA); (ii) there is no apparent localization of knowledge spillover amongst FPD technology latecomers; instead, higher citation frequencies of forerunners’ patents were found in latecomers’ FPD patents during the transition (1987–1996) and post-dominant design (1997–2005) stages and; and (iii) a few extraordinary peaks were found in the citation frequency of forerunners’ patents at long citation lags in latecomers’ FPD patents, particularly during the transition stage (1987–1996), indicative of the knowledge threshold which latecomers need to cross in order to catch up with forerunners.
