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 technologyrelevant papers is novel and offers new opportunities in research evaluation practices.展开更多

To assess the growth in industrially-important research, I conducted an appraisal of patents published between 1985 and 2005 on online databases using keywords chosen to select technologies arising as a result of biological inspiration. Whilst the total number of patents increased over the period examined, those with biomimetic content had increased faster as a proportion of total patent publications. Logistic regression analysis reveals that we may be a little over half way through an initial innovation cycle inspired by biological systems.展开更多

The price of materials employed for packaging food has traditionally been high and used to be more expensive than the food itself. Technological innovations made possible to produce packaging materials cheaply. One of these processes is known as co-extrusion. This technique makes a film with two or more layers with different plastics not laminating the layers together with an adhesive, eliminating the use of solvents and producing a film in just one step instead multiple steps. In this background, our paper relates to the evolution on packaging for foods by using patenting documents. A search for patent documents was performed on free patent databases using keywords and International Patent Classification (IPC) codes related to this technology. As results: (a) 17% of the 21,472 documents found are focused on multilayer packaging for food; (b) 12 countries hold more than 90% of patents (38% Japan; 23% The United States of America; 7% Canada and 6% Germany); and, (c) two peaks were perceived in the period of 1992-1994 and 2003, and matches, respectively, the Persian Gulf (1990-1991) and Iraq Wars (2003-invasion of Iraq), so the historical tendency is confirmed: "wars also generate scientific and technological innovations".展开更多

文摘Publication rate of patents can be a useful measure of innovation and productivity in fields of science and technology. To assess the growth in industrially-important research, I conducted an appraisal of patents published between 1985 and 2005 on online databases using keywords chosen to select technologies arising as a result of biological inspiration. Whilst the total number of patents increased over the period examined, those with biomimetic content had increased faster as a proportion of total patent publications. Logistic regression analysis reveals that we may be a little over half way through an initial innovation cycle inspired by biological systems.

文摘Product innovation can be achieved by analyzing leading products patents in the market.Different methods have been proposed for design around patent,commonly using the elimination or replacement of a single patent element However,the existing research fails to restore the position and function of the design around object in the original patent portfolio of enterprises,which often leads to the phenomenon of evading one patent and violating another.This paper proposes a method for design around patent through using the fusion of technologies of the evolution theory and bundle-type patent portfolio analysis in the initial stage of product development.The object system is analyzed to select technical opportunities through the evolutionary path of technologies and functional trimming methods to achieve circumvent barriers of bundle-type patents.The bundle patent portfolio is analyzed for the product evolution with a radar map.The technological evolution path is combined with the TRIZ innovation method to identify and solve the design problem.Patentability of the new design is evaluated using the patent system rules for innovative scheme difference from the original patent portfolio.The method is verified in a case study for the design of a glass-wiping robot.The design solution has been patented.

文摘Purpose:Following the typical features of the grey-rhino event as predictability and profound influence,we attempt to find a special pattern called the grey-rhino in eminent technologies via patent analysis.Design/methodology/approach:We propose to combine triadic patent families and technology life cycle to define the grey-rhino model.Firstly,we design the indicator rhino-index Rh=ST/SP and descriptor sequence{Rh},where ST and SP are the accumulative number of triadic patent families and all patent families respectively for a specific technology.Secondly,according to the two typical features of the grey-rhino event,a grey-rhino is defined as a technology that meets both qualitative and quantitative conditions.Qualitatively,this technology has a profound influence.Quantitatively,in the emerging stage,Rh≥Rae,where Rae is the average level of the proportion of triadic patent families.Finally,this model is verified in three datasets,namely Encyclopedia Britannica’s list for the greatest inventions(EB technologies for short),MIT breakthrough technologies(MIT technologies)and Derwent Manual Code technologies(MAN technologies).Findings:The result shows that there are 64.71%EB technologies and 50.00%MIT technologies meeting the quantitative standard of the grey-rhino model,but only 14.71%MAN technologies fit the quantitative standard.This falling trend indicates the quantitative standard of the grey-rhino model is reasonable.EB technologies and MIT technologies have profound influence on society,which means they satisfy the qualitative standard of the grey-rhino model.Hence,64.71%EB technologies and 50.00%MIT technologies are grey-rhinos.In 14.71%MAN technologies meeting the quantitative standard,we make some qualitative judgments and deem U11-A01A,U12-A01A1A,and W01-A01A as grey-rhino technologies.In addition,grey-rhinos and non-grey-rhinos have some differences.Rh values of grey-rhinos have a downward trend,while Rh values of non-grey-rhinos have a contrary trend.Rh values of grey-rhinos are scattered relatively in the early stage and centralize gradually,but non-grey-rhinos do not have this feature.Research limitations:There are four main limitations.First,if a technology satisfies the quantitative standard of the model,it is likely to be a grey-rhino but expert judgments are necessary.Second,we don’t know why it will be eminent,which involves technical contents.Thirdly,we did not consider the China National Intellectual Property Administration(CNIPA)and the German Patent and Trademark Office(DPMA)which also play important roles in worldwide patents,so we hope to expand our study to the CNIPA and the DPMA.Furthermore,we did not compare the rhino-index with other patent indicators.Practical implications:If a technology meets the quantitative standard,this can be seen as early warning signals and the technology may become a grey-rhino in the future,which can catch people’s attention in the emerging stage and make people seize the technical opportunity early.Originality/value:We define and verify a new pattern called the grey-rhino model in eminent technologies.
文摘Packaging is one of the most important methods of keeping the quality of food products for storage, transportation and end-use. The price of materials employed for packaging food has traditionally been high and used to be more expensive than the food itself. Technological innovations made possible to produce packaging materials cheaply. One of these processes is known as co-extrusion. This technique makes a film with two or more layers with different plastics not laminating the layers together with an adhesive, eliminating the use of solvents and producing a film in just one step instead multiple steps. In this background, our paper relates to the evolution on packaging for foods by using patenting documents. A search for patent documents was performed on free patent databases using keywords and International Patent Classification (IPC) codes related to this technology. As results: (a) 17% of the 21,472 documents found are focused on multilayer packaging for food; (b) 12 countries hold more than 90% of patents (38% Japan; 23% The United States of America; 7% Canada and 6% Germany); and, (c) two peaks were perceived in the period of 1992-1994 and 2003, and matches, respectively, the Persian Gulf (1990-1991) and Iraq Wars (2003-invasion of Iraq), so the historical tendency is confirmed: "wars also generate scientific and technological innovations".
文摘The performance and reliability of structural components are greatly influenced by the presence of any abnormality in them.To this purpose,structural health monitoring(SHM)is recognized as a necessary tool to ensure the safety precautions and efficiency of both mechanical and civil infrastructures.Till now,most of the previous work has emphasized the functioning of several SHM techniques and systematic changes in SHM execution.However,there exist insufficient data in the literature regarding the patent-based technological developments in the SHM research domain which might be a useful source of detailed information for worldwide research institutes.To address this research gap,a method based on the Co-Operative Patent Classification(CPC)codes is proposed in the current study.The proposed method includes the patent analysis of SHM in terms of its global publication trend and technology-based applications.This analysis is performed using patent database search tools,namely,IncoPat and Espacenet.The period ranging from 2005 to 2019 is selected to retrieve the required patent documents.A new approach termed as Patents’value is utilized to investigate the technological impact of a patent in the form of forward citations,technical stability,and scope of protection.The identification of emerging SHM techniques and forecasting of vacant technology is also part of current research work.The research results have revealed the increasing trend in the number of published patents each year related to various SHM technologies.In this regard,China,the United States,and South Korea are notified as to the major depositor countries,respectively.Hence,mapping of patent data in this research is an effort to illustrate the effectiveness of the proposed method to demonstrate the development trends and dynamic inventions over the time in SHM research domain to achieve the optimal damage inspections of various mechanical components.
