Patent Citation Analysis and Its Value in Research Evaluation: A Review and A New Approach to Map Technology-Relevant Research

Purpose: First, to review the state-of-the-art in patent citation analysis, particularly characteristics of patent citations to scientific literature (scientific non-patent references,SNPRs). Second, to present a novel mapping approach to identify technology-relevant research based on the papers cited by and referring to the SNPRs. Design/methodology/approach: In the review part we discuss the context of SNPRs such as the time lags between scientific achievements and inventions. Also patent-to-patent citation is addressed particularly because this type of patent citation analysis is a major element in the assessment of the economic value of patents. We also review the research on the role of universities and researchers in technological development, with important issues such as universities as sources of technological knowledge and inventor-author relations. We conclude the review part of this paper with an overview of recent research on mapping and network analysis of the science and technology interface and of technological progress in interaction with science. In the second part we apply new techniques for the direct visualization of the cited and citing relations of SNPRs, the mapping of the landscape around SNPRs by bibliographic coupling and co-citation analysis, and the mapping of the conceptual environment of SNPRs by keyword co-occurrence analysis. Findings: We discuss several properties of SNPRs. Only a small minority of publications covered by the Web of Science or Scopus are cited by patents, about 3%–4%. However, for publications based on university-industry collaboration the number of SNPRs is considerably higher, around 15%. The proposed mapping methodology based on a “second order SNPR approach” enables a better assessment of the technological relevance of research. Research limitations: The main limitation is that a more advanced merging of patent and publication data, in particular unification of author and inventor names, in still a necessity. Practical implications: The proposed mapping methodology enables the creation of a database of technology-relevant papers (TRPs). In a bibliometric assessment the publications of research groups, research programs or institutes can be matched with the TRPs and thus the extent to which the work of groups, programs or institutes are relevant for technological development can be measured. Originality/value: The review part examines a wide range of findings in the research of patent citation analysis. The mapping approach to identify a broad range of technology relevant papers is novel and offers new opportunities in research evaluation practices. Merit, Expertise and Measuremen

Determinants of patent citations in biotechnology: An analysis of patent influence across the industrial and organizational boundaries

The present paper extends the literature investigating key drivers leading certain patents to exert a stronger influence on the subsequent technological developments (inventions) than other ones. We investigated six key determinants, as (i) the use of scientific knowledge, (ii) the breadth of the technological base, (iii) the existence of collaboration in patent development, (iv) the number of claims, (v) the scope, and (vi) the novelty, and how the effect of these determinants varies when patent influence—as measured by the number of forward citations the patent received—is distinguished as within and across the industrial and organizational boundaries. We conducted an empirical analysis on a sample of 5671 patents granted to 293 US biotechnology firms from 1976 to 2003. Results reveal that the contribution of the determinants to patent influence differs across the domains that are identified by the industrial and organizational boundaries. Findings, for example, show that the use of scientific knowledge negatively affects patent influence outside the biotechnology industry, while it positively contributes to make a patent more relevant for the assignee's subsequent technological developments. In addition, the broader the scope of a patent the higher the number of citations the patent receives from subsequent non-biotechnology patents. This relationship is inverted U-shaped when considering the influence of a patent on inventions granted to other organizations than the patent's assignee. Finally, the novelty of a patent is inverted-U related with the influence the patent exerts on the subsequent inventions granted across the industrial and organizational boundaries

What are the Channels for Technology Sourcing? Panel Data Evidence from German Companies

Innovation processes within corporations increasingly tap into international technology sources, yet little is known about the relative contribution of different types of innovation channels. We investigate the effectiveness of different types of international technology sourcing activities using survey information on German companies complemented with information from the European Patent Office. German firms with inventors based in the US disproportionately benefit from R&D knowledge located in the US. The positive influence on total factor productivity is larger if the research of the inventors results in co-applications of patents with US companies. Moreover, research cooperation with American suppliers also enables German firms to better tap into US R&D, but cooperation with customers and competitors does not appear to aid technology sourcing. The results suggest that the “brain drain” to the US can have upsides for corporations tapping into American know-how

Markets for technology (why do we see them, why don't we see more of them and why we should care)

This essay explores the nature, the functioning, and the economic and policy implications of markets for technology. Today, the outsourcing of research and development activities is more common than in the past, and specialized technology suppliers have emerged in many industries. In a sense, the Schumpeterian vision of integrating R&D with manufacturing and distribution is being confronted by the older Smithian vision of division of labor. The existence and efficacy of markets for technology can profoundly influence the creation and diffusion of new knowledge, and hence, economic growth of countries and the competitive position of companies. The economic and managerial literatures have touched upon some aspects of the nature of these markets. However, a thorough understanding of how markets for technology work is still lacking. In this essay we address two main questions. First, what are the factors that enable a market for technology to exist and function effectively? Specifically we look at the role of industry structure, the nature of knowledge, and intellectual property rights and related institutions. Second, we ask what the implications of such markets are for the boundaries of the firm, the specialization and division of labor in the economy, industry structure, and economic growth. We build on this discussion to develop the implications of our work for public policy and corporate strategy

Strangers in the night:a comparative study on the socio-legal difficulties of importing America’s Bayh-Dole legislation to South African universities

In 2008, the South African parliament passed the Intellectual Property Rights from Publicly Financed Research and Development Act, which came into effect on 2 August 2010. In doing so, South Africa sought to replicate the apparent success of the United States of America’s Bayh-Dole legislation. One of the express objectives of the Bayh-Dole Act is the increase in university-industry collaborations. Whilst U-I has not been expressly stated as a primary aim of the IPR Act, the legislative history has demonstrated that issues relating to U-I have permeated the political landscape from the inception of the IPR Act. It is therefore relevant - although hitherto unexplored - to consider whether South Africa’s IPR Act might have the same supposedly positive effect on U-I experienced by the Bayh-Dole Act. In answering this question, this paper chooses to focus on two factors which may be considered particularly pertinent in light of South Africa’s recent socio-legal landscape, namely (a) the lack of substantive patent examinations, and (b) government investment in higher education. To this end, it will be argued that the IPR Act will only serve to have a negative effect on U-I, if any at all

Department of Management EngineeringFirms participating in printer industries have invested their constrained resources into technology development in order to sustain their competitiveness in the industry. Considering the fast-changing market circumstances, each firm???s own investment decisions on technology portfolio may directly affect their performance. In this study, we analyzed patent data, namely number of forward citations and technological classification data (CPC). Using this data, the technological portfolio of a specific firm can be identified, which can further help our understanding on firms??? R&D investment strategies. Number of studies mainly focused on patent class combinations of individual technology level, but portfolios of patent class at a firm level have been understudied. In this study, we tracked the change of class composition within each firms??? technological patents??? portfolio and attempted to identify practical and theoretical implications to portfolio management. We utilized Entropy Index, Co-occurrence and cosine similarities measurements for each indicating diversification, patent scope and portfolio similarities within each patents??? classification subclasses. Additionally, performance evaluation of each portfolio is conducted using forward citation data. This paper shows that in-depth patent data analysis can allow us to explore deeper insights at various levels, individual technology, products and product lines, and firms sufficing different stories.ope

Current policy issues in the governance of the European patent system

The European Parliament has been working towards building a discussion platform and a resource for further policy actions in the field of intellectual property rights. The Science and Technology Options Assessment Panel has set the goal of further enlarging the area of investigation in light of recent policy developments at the European level. In particular, the current study covers current policy issues in the governance of the European patent system, such as the backlog issue, the enhancement of patent awareness within the European Parliament, patent enforcement, the regional dimension of intellectual property in Europe, patents and standardisation, the use of existing patents, and patents and competition. These issues were discussed in the conference with stakeholders from European to national patent offices, from private to public sector actors. As a result of the conference, it was stated the need for an IP strategy for Europ

To date, the approaches adopted by industry seem more designed for internal consumption and are usually contingent on particular technologies and/or sector perspectives. Typically, there is a lack of transparency in the methodologies and data used to form the basis of claims, making much of this an unreliable basis for policy formulation. The research approaches we found are characterised by a number of features that can be summarised as a preference for reactive approaches that look to establish snapshots of an important issue at the time of investigation. Most studies are ad hoc in nature and on the whole we found a lack of sustained longitudinal approaches that would develop the appreciation of change. Typically the studies are designed to address specific hypotheses that might serve to support the position of the particular commissioning body. To help bring some structure to this area, we propose a framework for the assessment of the volume of infringement in each different area. The underlying aim is to draw out a common approach wherever possible in each area, rather than being drawn initially to the differences in each field. We advocate on-going survey tracking of the attitudes, perceptions and, where practical, behaviours of both perpetrators and claimants in IP infringement. Clearly, the nature of perpetrators, claimants and enforcement differs within each IPR but in our view the assessment for each IPR should include all of these elements. It is important to clarify that the key element of the survey structure is the adoption of a survey sampling methodology and smaller volumes of representative participation. Once selection is given the appropriate priority, a traditional offline survey will have a part to play, but as the opportunity arises, new technological methodologies, particularly for the voluntary monitoring of online behaviour, can add additional detail to the overall assessment of the scale of activity. This framework can be applied within each of the IP right sectors: copyright, trademarks,patents, and design rights. It may well be that the costs involved with this common approach could be mitigated by a syndicated approach to the survey elements. Indeed, a syndicated approach has a number of advantages in addition to cost. It could be designed to reduce any tendency either to hide inappropriate/illegal activity or alternatively exaggerate its volume to fit with the theme of the survey. It also has the scope to allow for monthly assessments of attitudes rather than being vulnerable to unmeasured seasonal impacts

Innovation Institution and Spatial Transfer of Energy Industry: The Case of Jiangsu Province, China

This study aims to explore the effect of innovation institution on spatial transfer of energy industry in Jiangsu, China. We focus on the disparity of innovation and energy industry, and analyze the spatial transfer difference in different types of energy industry, rather than view energy industry as a whole. The study demonstrates the spatial change of energy industry at regional level and maps the spatial pattern at city level. The study chooses intellectual property rights (IPRs) protection intensity, authorization patents and local research and development (R&D) investment as the proxy of innovation. Using official data and employing panel fixed-effect model at city-industry level, we conclude (a) innovation abilities significantly influence the spatial transfer of energy industry in Jiangsu. Especially, due to the different time, IPRs protection, patent counts, and R&D investment have different effects on different regions in Jiangsu; (b) 2010 is an important turning point for energy industry development in Jiangsu, and after 2010, the energy industry begins to shift to the middle and northern Jiangsu, whereas the spatial pattern of energy industry in coastal cities is basically unchanged; (c) there is a great difference between the regions in Jiangsu Province, and industrial upgrading has not been achieved in northern Jiangsu

On patent legislation, patent enforcement and economic growth: empirical evidence from developed and developing countries

This study investigates the long-term effects of national patent legislation and enforcement systems on the economic development of 42 countries. The econometric methodology that has been adopted involves the estimation of three different models, namely, the pooled, the fixed effects and the random effects models whilst the specification of the economic development regressions is a variant of the standard growth specifications encountered in relevant studies. The empirical analysis is conducted in the context of the time period following the imposition of trade-related aspects of intellectual property rights (TRIPs). The results show that the extension and strengthening of patent legislation resulting from TRIPs have had a negative impact on economic development. In contrast, stronger levels of patent enforcement have had a positive effect overall and particularly for developing economies while negative for developed economies
