Interregional inventor networks as studied by patent coinventorships   总被引:3,自引:0,他引:3  
We study the structure of the interregional inventor networks in Sweden by examining the residence of inventors and coinventors involved in Swedish patent applications to the European Patent Office. Several factors are found to influence the spatial affinity of regions. We find that spatial affinity extends beyond the region if it has less own R&D-related resources (business R&D, university R&D and patenting); if it is close to the other region and if it is relatively small. The resources of that other region plays a positive role if, in analogue fashion, that region has more R&D-related resources.  相似文献

当前我国高校科研人员的专利行为快速增长,如何有效平衡学术研究的公共属性和专利行为的私权属性是高校面临的重要问题。以2008-2017年112所“211”高校及省部级共建高校多专业科研人员的专利行为和学术影响力相关数据构建研究数据库,综合运用负二项回归和二元Logistics回归,实证分析高校科研人员专利行为在“申请-授权”和“授权-交易”两阶段特征对其学术影响力的影响效应。研究表明:高校科研人员的专利申请数量与学术影响力之间存在显著的倒U型关系,随着专利申请数的增加,学术影响力受到的正向影响会增加,当专利申请数达到年均35项左右时,出现负向影响;当高校科研人员采用独占许可进行专利交易时,学术影响力会受到显著的抑制效应。为我国高校专利的全过程管理和相关政策制定提供了参考依据。  相似文献

This paper analyses whether strategic motives for patenting influence the characteristics of companies’ patent portfolios. We use the number of citations and oppositions to represent these characteristics. The analysis is based on survey data from German companies, which are combined with EPO data covering applications from 1991 to 2000. We find clear evidence that the companies’ patenting strategies are related to the characteristics of their patent portfolios. First, companies using patents in the traditional way to protect their technological knowledge base receive a higher number of forward citations for their patents. Second, the motive of offensive - but not of defensive - blocking is related to a higher incidence of oppositions, whereas companies using patents as bartering chips in collaborations receive fewer citations and fewer oppositions to their patents.  相似文献

Examiners’ instructions and academic studies on patent validity determination focus on identification of “blocking” citations that invalidate claims in applications as non-novel or obvious, generally ignoring the non-blocking majority as irrelevant to validity. Recently available datasets allow us to identify, for the first time, “forward” citations received by applications before grant, as well as “backward” citations in those applications, and distinguish those identified by the examiner as blocking (submitted mainly by examiners), as well as non-blocking examiner and applicant citations. Categorical analysis confirms that blocking citations in an application strongly negatively predict its grant, but positively predict grant of the cited blocking applications. Non-blocking applicant and examiner citations in an application equally strongly predict its grant, but do not predict grant of cited applications. We test whether expected value – measured by applicant forward citations to the application prior to its grant – affects probability of grant, with negative results. These findings expand our understanding of the scope of examiners’ and applicants’ roles as mediators of validity-relevant information in applications.  相似文献

What national policies are most efficient in promoting the commercialization of university-generated knowledge? We address this question by characterizing and evaluating the policy pursued in Sweden and the US, two countries that put a great deal of resources into university R&D, but follow very different models for commercialization. Despite a leading academic record, there is an impression of laggard rates of commercialization of academic research results in Sweden. Although there exist no micro data to evaluate this impression, we argue that it is likely to be true in part due to the top-down nature of Swedish policies aimed at commercializing these innovations as well as an academic environment that discourages academics from actively participating in the commercialization of their ideas. This sits in stark contrast to a US institutional setting characterized by competition between universities for research funds and research personnel, which in turn has led to significant academic freedoms to interact with industry, including significant involvement in new firms.  相似文献

We propose an empirical strategy to estimate competition in innovation markets. Our method relates firms’ market return on equity to information about patent citation patterns. Two innovations are implemented in the methodology. First is the application of daily abnormal stock returns rather than annual measures of Tobin's q. Second is the creation of citation patterns related to the area of science a firm patents in as represented by the detailed patent classification system. We find that markets positively reward firms when patents are granted. We further find that firm's market value increases when its patent portfolio is cited. We find evidence of competition in innovation markets. The market reacts at the time that the citation occurs and does not anticipate future citations at the time of patenting. Holding this effect constant, we find that citations from patents in the same area of science tend to reduce market value. We interpret these findings as consistent with more citations indicating more valuable intellectual property but citations from competing technologies decreasing it.  相似文献

Patent scope is one of the important aspects in the debates over “patent quality.” The purported decrease in patent quality over the last decade or two has supposedly led to granting patents of increased breadth, decreased clarity, and questionable validity (in part due to over-breadth). Such patents allegedly diminish the incentives for innovation due to increased transaction costs in the market for technology, more frequent disputes and litigation, trolling behavior, and breakdowns in bargaining. This paper focuses on the patent examination process at the PTO, highlighting the relationship between patent scope and the patent examination process. We develop and validate two measurements of patent scope: independent claim length and independent claim count. These metrics—in contrast to other measurements of patent scope—can be calculated before and after examination and enable us to provide the first large-scale analysis of trends in patent scope changes during the examination process. Our results show that applications with narrower scope are associated with a higher probability of grant and a shorter and less intense examination period in comparison to applications with broader scope. Further, we find that the examination process itself tends to narrow the scope of patents relative to the scope at filing, and that the changes are more significant when the duration and intensity of examination is increased. We explain our metrics and make our data available in a public use dataset, which we hope will encourage more research in the evaluation of patent scope, patent examination, and patent quality more broadly.  相似文献

As university involvement in technology transfer and entrepreneurship has increased, concerns over the patenting and licensing of scientific discoveries have grown. This paper examines the effect that the licensing of academic patents has on journal citations to academic publications covering the same scientific research. We analyze data on invention disclosures, patents, and licenses from the University of California, a leading U.S. academic patenter and licensor, between 1997 and 2007. We also develop a novel “inventor-based” maximum-likelihood matching technique to automate and generalize Murray's (2002) “patent-paper pairs” methodology. We use this methodology to identify the scientific publications associated with University of California patents and licenses.Based on a “difference-in-differences” analysis, we find that within our sample of patented academic discoveries, citations to licensed patent-linked publications are higher in the three years after the license, although this difference is not statistically significant. We then disaggregate our sample into (a) patented discoveries that are likely to be used as “research tools” by other researchers (based on the presence of material transfer agreements (MTAs) that cover them) and (b) patented discoveries not covered by MTAs. Citations to publications linked to licensed patents in the latter subset (not covered by MTAs) are higher for publications linked to licensed patents, and this difference is statistically significant. In contrast, licensing of patented discoveries that are also research tools is associated with a reduction in citations to papers linked to these research advances, raising the possibility that licensing may restrict the flow of inputs to “follow-on” scientific research.  相似文献

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

Scientific breakthroughs coming from universities can contribute to the emergence of new industries, such as in the case of biotechnology. Obviously, not all research conducted in universities leads to a radical change from existing technological trajectories. Patents and patent dynamics have long been recognized as critical in understanding the emergence of new technologies and industries. Specifically, patent citations provide insight into the originality of a discovery that has received patent protection. Yet while a large body of literature addresses the impact of patent originality on various firm performance measures, we address the question of what conditions drive patent originality in the process of knowledge creation within the university. Using data on patented cancer research, we examine how research context – as reflected by the funding source for each scientist – is associated with patent originality. We find that when university scientists are partly funded by their own university, they have a higher propensity to generate more original patents. By contrast, university scientists funded either by industry or other non-university organizations have a lower propensity to generate more original patents. The significance of our findings in the cancer research setting call for further research on this question in other research fields.  相似文献

A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets.  相似文献

We investigate how universities’ research quality shapes their engagement with industry. Previous research has predominantly found a positive relationship between academics’ research quality and their commercialization activities. Here we use industry involvement measures that are broader than commercialization and indicate actual collaboration, i.e. collaborative research, contract research and consulting. We hypothesise that the relationship between faculty quality and industry engagement differs across disciplines, depending on complementarities between industrial and academic work, and resource requirements. Using a dataset covering all UK universities, we find that in technology-oriented disciplines, departmental faculty quality is positively related to industry involvement. In the medical and biological sciences we find a positive effect of departmental faculty quality but establish that this does not apply to star scientists. In the social sciences, we find some support for a negative relationship between faculty quality and particularly the more applied forms of industry involvement. The implication for science policy makers and university managers is that differentiated approaches to promoting university-industry relationships are required.  相似文献

专利市场是经济活动中效率最为低下的市场之一。一方面,专利属于无形资产,很难评判其价值。另一方面,由于信息不对称,市场参与双方(发明人和使用者)均面临很大的搜寻和交易成本。然而较少有文献实证记录这些市场摩擦所带来的后果。本文记录中国个人专利申请的一个特别现象:与企业专利相比,个人专利被广泛认为质量较差;然而另一方面,个人专利在授权后的维持时间却长于企业专利。本文认为专利市场摩擦可以一定程度上解释该现象:由于搜索成本和信息不对称,相对于企业来说,个人发明人需要更长时间才能将其专利许可或转让给可以商业化的公司。个人发明人往往需要这些转让收益来收回发明的投资成本,为此他们会努力寻求潜在的授予方,而不得不维持专利到更长的时间。 本文提供一些实证证据来支持这个假说。在专利质量比较过程中,本文基于中国国家知识产权局的数据库,整理并建立了中国专利申请的详细数据并构建了若干质量指标。同时,作者利用谷歌专利数据库补充了专利权利要求项数量和专利引证这两个指标,为中国专利质量分析、知识传递与溢出提供了重要的数据来源。  相似文献

This paper investigates domestic and foreign innovating firms’ determinants of R&D collaboration with domestic universities and public knowledge institutes in Finland and the Netherlands. We put particular emphasis on the impact of incoming academic spillovers on the probability to co-operate with these public R&D institutes.Based on data from Community Innovation Surveys we find that foreign firms in the Netherlands are less likely to co-operate with domestic public knowledge institutions than domestic firms, while in Finland no significant difference can be detected. Another result is that incoming knowledge spillovers are an important determinant for R&D collaboration with domestic public knowledge institutions in both countries. In case of foreign firms in Finland, incoming knowledge spillovers affect the probability to co-operate with public knowledge institutions more positively compared to domestic firms. For the Netherlands no substantial difference could be found in this respect. Further, innovating firms in Finland that require academic or basic knowledge do not co-operate significantly more with public knowledge institutions than those that need applied knowledge. At the same time they are willing to share knowledge with public R&D partners. In the Netherlands innovating firms that require relatively more basic than applied knowledge, increase the probability of co-operation with Dutch universities and public knowledge institutions but there is reluctance to share proprietary knowledge with public R&D partners. For both countries no significant difference between foreign and domestic firms with regard to academic knowledge requirements could be found. This raises the issue whether Finnish innovation policies with a strong focus on R&D co-operation provide incentives for strategic behaviour by domestic public partners to put more emphasis on applied research.  相似文献

Knowledge production and scientific research have become increasingly more collaborative and international, particularly in pharmaceuticals. We analyze this tendency in general and tie formation in international research networks on the country level in particular. Based on a unique dataset of scientific publications related to pharmaceutical research and applying social network analysis, we find that both the number of countries and their connectivity increase in almost all disease group specific networks. The cores of the networks consist of high income OECD countries and remain rather stable over time. Using network regression techniques to analyze the network dynamics our results indicate that accumulative advantages based on connectedness and multi-connectivity are positively related to changes in the countries’ collaboration intensity whereas various indicators on similarity between countries do not allow for unambiguous conclusions.  相似文献

We evaluate the impact of the EC's Seventh Framework Programme, a large-scale research subsidy programme, on the innovation activities of subsidized firms, with a particular regard to industry–university partnerships. Using matching and difference-in-difference estimation, we find a positive effect on a range of innovation indicators. The number of project participants in general and university participants in particular positively affect performance, suggesting knowledge spillovers between project members. Research centres, on the other hand, do not exert positive externalities. We also find that the benefits of collaborating with universities are amplified by their academic quality.  相似文献

Despite their growing importance for firm innovation strategy and frequent appearance in U.S. patent policy debates, how continuing patent applications are used remains unclear. Turn-of-the-century reforms strongly limited opportunities to extend patent term and surprise competitors, but continuing applications have steadily risen since. We argue that they retain a subtle use, as applicants can file continuations to keep prosecution open and change patent scope after locking in gains with the initial patent. We document a sharp drop in parent abandonment and rise in continuations per original patent after the reforms. Continuing applications are more privately valuable than original patents, are filed in more uncertain contexts, for higher value technologies, by more strategic applicants, and react strongly to the notice of allowance. The evidence supports a current strategic use of continuing applications to craft claims over time.  相似文献
