There is a considerable volume of prior research on the relationship between innovation and patents. Those research studies reveal that patents contain a great deal of noise, and unless a correction is made in terms of the value of individual patents, a simple count of the number of patents does not constitute a very useful indicator. From research that has been conducted for the purpose of finding such an indicator to show the value of individual patents (that is, research to identify the characteristics of valuable patents), many kinds of value indicators have been proposed. Nevertheless, research hitherto has focused primarily on business or private value derived from the possession of patents, and little attention has been paid to value in terms of technical knowledge or social value. In a survey of inventors conducted by RIETI in 2007, terminology describing broad concepts was used when questioning inventors about the value of individual patents, and this has provided an excellent opportunity to analyze the multiple factors lying behind the value of patents and how they impact one another.The purpose of this research is to use data from the RIETI survey of inventors and structural equation modeling methods to elucidate the relationships between the technological and business value of patents, and the latent factors that influence them. The findings show that a scientific-technological motive for inventors would have a positive effect on both the business and technological value, meanwhile, the monetary or promotion motive would not have any direct effects on the value of a patent. The model also suggests that academic linkage would have a strong positive effect on the technological value but a weak negative effect on the business value. Furthermore, these relationships differ more markedly according to technological field. 相似文献

US faculty patenting: Inside and outside the university 总被引：2，自引：0，他引：2
In a sample of 5811 patents with US faculty as inventors, 26% are assigned solely to firms rather than universities as dictated by US university employment policies and Bayh-Dole. We relate assignment to patent characteristics, university policy, and inventor field. Patents assigned to firms (whether established or start-ups with inventor as principal) are less basic than those assigned to universities suggesting firm assigned patents result from faculty consulting. Assignment to inventor-related start-ups is less likely the higher the share of revenue inventors receive from university-licensed patents. Firm assignment also varies by inventor field and whether the university is public or private. 相似文献

Academic inventors as brokers 总被引：4，自引：0，他引：4
Francesco Lissoni 《Research Policy》2010,39(7):843-857
Academic inventors are university scientists who appear as designated inventors of patents owned either by business companies, academic institutions or individuals. We analyse their relationships with co-inventors, who may be either academic colleagues, students, or, very often, industrial researchers. Gould and Fernandez's (1989) taxonomy of ‘brokerage’ roles is adjusted to patent data, and complemented with information drawn from both academic inventors’ publications and replies to a short questionnaire. Only very few academic inventors are found to hold brokerage positions. Such inventors have a large number of patents, a strong publication record and a higher-than-average share of patents held by companies, rather than universities. Relationships of academic inventors with co-inventors from industry are weaker and less likely to be maintained than those with co-inventors from academia. Academic inventors in gatekeeping positions (between university and industry) maintain the strongest ties with all types of co-inventors. 相似文献

Stars hold a large portion of organizational knowledge, and their sudden absence may have non-trivial consequences for firms. In this study, I investigate what happens to the knowledge of star inventors following their absence. In particular, I consider the composition of stars' ties with coinventors and examine how it affects the future use of stars' knowledge (i.e., patents). Using the death of star inventors as an exogenous cause for their absence in firms, I find that the use of a star's patents in a firm's subsequent inventive efforts declines following the star's death. The results also indicate that when star inventors frequently collaborate with coinventors, the negative effect of stars' absence on the future use of their knowledge is somewhat alleviated. Further, the presence of central inventors in stars' collaboration networks increases the relative use of stars' knowledge in future inventions. The findings inform managers about conditions that favor “passing the torch” of knowledge from stars to their peers. 相似文献

We examine the impact of local and foreign labor mobility in India by modeling one regional and one global network, each of which captures the inter-organizational mobility of inventors. Our analysis of the regional network shows that, within India, the productivity of inventors does not improve when they move from foreign to Indian organizations. In the global network, we find that Indian organizations remain located in the periphery as a result of employing a small number of inventors from foreign organizations. However, in the instances when inventors are hired from foreign organizations, they are able to produce patents with a higher impact in comparison to inventors hired from other Indian organizations. Furthermore, when the inventors are hired from abroad, the impact of their patents is even higher in comparison. The implications of these findings for innovation and policy in the emerging economy context are discussed. 相似文献

Mapping technologies into industries is frequently required in empirical innovation studies, but many concordances only provide coarse mappings. We develop a novel concordance between industries and technologies making use of linked inventor-employee data for a large sample of German patents filed at the European Patent Office between 1999 and 2011. Inventors listed on these patents are matched and disambiguated with German social security records. Employment data recorded in this database include detailed industry codes describing the industrial activities of the inventors’ establishments. These linked microdata allow us to identify the precise industrial origin of inventions, combine them with technology classifications from the inventors’ patents and to generate novel concordance tables. We evaluate our approach by comparing the concordances with existing work. Moreover, in an empirical application, we find that patent based indicators represent valid proxies for the innovation performance of industries and thus help to measure innovation in the absence of other survey based indicators. Service sector innovation activities, however, appear to be barely represented by the patenting activities of inventors and establishments. 相似文献

Networks of inventors and the role of academia: an exploration of Italian patent data 总被引：3，自引：0，他引：3
This paper proposes a quantitative analysis of social distance between Open Science and Proprietary Technology. A few general properties of social networks within both realms are discussed, as they emerge from the new economics of science and recent applied work on “small worlds”. A new data-set on patent inventors is explored, in order to show that social networks within Proprietary Technology are much more fragmented than Open Science ones, except for science-based technologies. Two propositions are then put forward on the “open” behaviour expected from academic inventors, namely university scientists getting involved in Proprietary Technology networks by signing patents. Both propositions are confirmed by data, which show academic inventors to be more central and better connected than non-academic ones. The database and methodology produced for this paper are suggested to be relevant for the more general debate on the role of geographical and cognitive distance in university-industry technology transfer. 相似文献

How team composition exactly influences innovation outcomes remains a complex and unsolved puzzle in the literature on creativity and innovation. Our study differentiates two types of team technology-related diversity—technological dissimilarity and technological variety, and investigates their influences on the impact of an invention created by a team. Analyses of over half million U.S. utility patents in the 1991–2005 period invented by teams reveal that technological variety of team inventors has a positive effect on invention impact, and that technological dissimilarity between team inventors plays both positive and negative roles, eliciting an inverted U-shaped effect. In addition, we find that the positive effect of dissimilarity is significantly reduced after controlling for variety. Theoretical and practical implications of our findings are discussed. 相似文献

The mobility of inventors leaves behind their patented inventions at sourcing firms, yet there is little scholarly insight into how firms handle those intellectual properties. We investigate this important issue by developing a framework of tacit-codified knowledge interdependence. We theorize that tacit and codified knowledge offer the intellectual and legal pillars of corporate inventions, which complement each other in value creation. Inventor mobility decouples the two pillars and reduces the maintenance likelihood of the left-behind patents. The negative impact is greater for inventions that are complex or rely less on internal prior art because the tacit knowledge loss is more destructive and unrecoverable. However, when inventors move to competing or litigious target firms, the relationship between mobility and patent maintenance becomes less negative or even turns positive because the left-behind patents can be leveraged to hedge against the risk of knowledge leakage. Applying a two-stage Coarsened Exact Matching approach to construct a sample of 36,204 U.S. patents with comparable leaving and staying inventors from public firms between 1983 and 2010, we find strong evidence supporting our framework. Our findings highlight the intricate interdependence of tacit and codified knowledge in corporate inventions and add to the literatures on inventor mobility and intellectual property management. 相似文献

This paper examines the role of various inter-organizational relationships in patent development, and how these relationships contribute to patent competitiveness. It takes the perspective of individual inventors and describes how they utilize external knowledge in the development of patents. Based on a case study of a European telecom operator, we found interaction with R&D consortia, suppliers and customers to support inventors in the development of new ideas for patents and in solving related problems. In terms of patent competitiveness, buyer-seller relationships were more valuable for an operator than R&D consortia relationships, as they reduced the market and technology uncertainty related to the patent. 相似文献

We investigate the relationship between patenting activity and the population size of metropolitan areas in the United States over the last two decades (1980-2001). We find a clear superlinear effect, whereby new patents are granted disproportionately in larger urban centers, thus showing increasing returns in inventing activity with respect to population size. We characterize this relation quantitatively as a power law with an exponent larger than unity. This phenomenon is commensurate with the presence of larger numbers of inventors in larger metropolitan areas, which we find follows a quantitatively similar superlinear relationship to population, while the productivity of individual inventors stays essentially constant across metropolitan areas. We also find that structural measures of the patent co-authorship network although weakly correlated to increasing rates of patenting, are not enough to explain them. Finally, we show that R&D establishments and employment in other creative professions also follow superlinear scaling relations to metropolitan population size, albeit possibly with different exponents. 相似文献

Using a unique database on Swedish patents owned by small firms and individuals, survival models estimate how different factors influence the decision to commercialize the patents. Such an analysis has seemingly never previously been undertaken. Since the owners know more about the patents than potential external financiers, problems related to asymmetrical information are present. To overcome these problems when inventors and small technology-based firms need financing, Sweden has for a long time relied on government support rather than private venture capital firms. The empirical results show that the larger is the share of patent-owners’ costs covered by government financial support during the R&D phase, the lower is the probability of patents being commercialized. This lower degree of commercialization is likely to depend on (1) the soft terms of the government loans, where the patent owner can avoid paying back the loan if the patent is never commercialized and/or (2) that the government is not able to select promising projects. The first explanation is related to moral hazard and the second one to adverse selection. The policy suggestion is for government to change the design of the loans, to base them on firms rather than projects. 相似文献

Academics and policy makers are investigating the relations between science and technology in the emerging field of nano science and technology (NST) and the effectiveness of different institutional regimes. We use multiple indicators to analyze the performance of inventors working in NST. We clustered patents into three groups according to the scientific curricula of the inventors. The first group consists of patents whose inventors are all authors of at least one scientific publication in NST, while the second is made up of patents invented by individuals who have no scientific publication in the field. Thirdly, we isolated those patents that have at least one inventor who is also author of at least one scientific publication in NST. The underlining presumption of this classification is that of a proxy of different institutional complementarities of inventive collective action in NST. 相似文献

Implementing Bayh-Dole-like laws: Faculty problems and their impact on university patenting activity 总被引：1，自引：0，他引：1
Nicola Baldini 《Research Policy》2009,38(8):1217-1224
The implementation of a Bayh-Dole-like legislation outside the US is still a major concern that needs to be addressed. I fill this gap in two ways. First, I report the results of a faculty survey on obstacles to patenting activity in Italian universities, targeted both to inventors and to those non-inventors which reported to engage in university patenting activity and to give up before any patents could be filed. Second, I investigate their effect in a regression model using universities’ patent counts as the dependent variable. Results show that obstacles to university patenting activity reduce to four dimensions: lack of support mechanisms (including insufficient reward for researchers, lack of a TTO, lack of funds to cover patenting costs), commercialisation problems, too heavy teaching and administrative duties, and personal/cultural problems (related to the scarce knowledge of institutional-level patent regulations and to the “open science” mentality of the university). Among them, however, only the lack of support by the university administration reduces the patent counts. Publication productivity has an inverted U-shaped relation with patent counts, but the overall effect is still largely positive, given the current publication levels. 相似文献

Today's Edisons or weekend hobbyists: technical merit and success of inventions by independent inventors 总被引：1，自引：0，他引：1
We set out to determine if independent inventors can be considered “heroes” or “hobbyists”, that is, if they produce the most or the least influential inventions in a product category. We study patented inventions by independent and firm-based inventors by comparing patents along four dimensions: Patent citation impact, detail, scope, and maintenance. Examining 225 tennis racket patents granted in the US between 1981 and 1991, we find that independent inventors are a heterogeneous group who generate inventions that are overrepresented both among the most impactful and the least impactful patents. The metrics we develop provide insight into ex ante identification of the importance of inventions. 相似文献

Economic theory views patents as policy instruments aimed at fostering innovation and diffusion. Three major implications are drawn regarding current policy debates. First, patents may not be the most effective means of protection for inventors to recover R&D investments when imitation is costly and first mover advantages are important. Second, patentability requirements, such as novelty or non-obviousness, should be sufficiently stringent to avoid the grant of patents for inventions with low social value that increase the social cost of the patent system. Third, the trade-off between the patent policy instruments of length and breadth could be used to provide sufficient incentives to develop inventions with high social value. Beyond these three implications, economic theory also pleads for a mechanism design approach: an optimal patent system could be based on a menu of different degrees of patent protection where stronger protection would involve higher fees, allowing self-selection by inventors. 相似文献

This paper addresses the question of national differences as regard the number of triadic patents applied for by inventors from several OECD countries. The key idea is to determine whether such differences should be attributed to differences in R&D expenditures or rather to some other reasons, mainly institutional or behavioural ones. With this aim in view, both a macro-economic analysis, based on aggregate data for triadic patent counts and R&D expenditures and a micro-economic analysis based on firms’ data from three selected sectors are performed. In both cases, the methodological focus is made on the introduction, the definition and the estimation of a national index of relative efficiency in standard count data models. The main empirical findings are that there is a strong heterogeneity in terms of performance among European countries and a strong intra-country heterogeneity among sectors. This suggests that, in the field of innovation policies, there is a need for “tailored” solutions reflecting the specificities of each innovation system. Moreover, we show that European countries over-perform the United States in some high-tech sectors where the leadership of American firms is traditionally alleged, whereas European firms fail to keep up in more traditional sectors. 相似文献

We examine patent licensing business models of non-practicing entities that generate revenue by selling, licensing, or litigating patents. They may also pursue R&D activities, invent new technologies, or provide services to inventors or product companies. We describe their business models and patent market behavior and then compare their litigation strategies against product companies using a matched sample of highly comparable patents. The main differences among patent licensing firms stem from their technological capabilities, patent portfolio sizes, and external relationships. We find that licensing firms with technological capabilities often pursue litigation until decision and engage in forum shopping. In contrast, litigation incidence, parties involved, and outcomes are primarily determined by patent characteristics, not entity types. Licensing business models drive the acquisition of certain types of patents that influence the outcomes of the patent system. We argue that patent policy should strengthen mechanisms to discover invention quality rather than focus on the amount of litigation or types of entities. 相似文献
