By using a sample of 793 inventors drawn from the PatVal-EU dataset, this paper explores three aspects of patent production at the individual inventor level: (1) the number of EPO patents that the inventors produce; (2) the average value of their inventions; (3) the production of the most valuable patents. By jointly estimating the three equations we find that the inventors’ level of education, employment in a large firm, and involvement in large-scale research projects positively correlate with quantity. Yet, apart from the size of the research project, none of these factors directly influence the expected value of the inventions. They do, however, have an indirect influence, as we find that the number of patents explains the probability of producing a technological hit (the maximum value). Also, there is no regression to the mean in the invention process at an individual level, as the number of inventions that an inventor produces is not correlated with the average value. 相似文献

Germany is one of few countries in which the monetary compensation for inventors is not only determined by negotiations between employer and employee-inventor, but also by relatively precise legal provisions. In this paper, we describe the characteristics of the German Employees’ Inventions Act (GEIA) and discuss which incentives it creates. We rely on responses from a recent survey of 3350 German inventors to test hypotheses regarding this institution. We conclude from our data that the law creates substantial monetary rewards for productive inventors. The qualitative responses from our survey confirm this view, but also point to a number of dysfunctional effects. 相似文献

To successfully generate more valuable technologies from accessing basic research knowledge, firms need to combine institutional and individual level bridges to universities and research institutes active in basic research. This combination is particularly important when the new technology builds on scientific prior art. While mobile inventors are needed to transfer and translate basic knowledge into new technologies, partnerships provide the commitment, resources and incentive structure to integrate this basic research knowledge more effectively into the firm’s innovation process, thus improving the value capture from mobile inventors. Our findings in the micro-electronics field illustrate the importance of jointly accounting for firm and inventor level industry-science links to assess their effectiveness and provides evidence on complementarity from using both. Furthermore, identifying the scientific nature of the technology projects critically determines whether the combination of these links allow to capture more value. 相似文献

Reconsidering the Bayh-Dole Act and the Current University Invention Ownership Model 总被引：1，自引：0，他引：1
The Bayh-Dole Act of 1980 provided U.S. universities with the right to commercialize employees’ inventions made while engaged in government-funded research. This paper argues that the current university invention ownership model, in which universities maintain de jure ownership of inventions, is not optimal either in terms of economic efficiency or for advancing the social interest of rapidly commercializing technology and encouraging entrepreneurship. We argue that this model is plagued by ineffective incentives, information asymmetries, and contradictory motivations for the university, the inventors, potential licensees, and university technology licensing offices (TLOs). These structural uncertainties can lead to delays in licensing, misaligned incentives among parties, and obstacles to the flow of scientific information and the materials necessary for scientific progress. The institutional arrangements within which TLOs are embedded have encouraged some of them to become revenue maximizers, rather than facilitators of technology dissemination for the good of the entire society.We suggest two alternative invention commercialization models as superior alternatives. The first alternative is to vest ownership with the inventor, who could choose the commercialization path for the invention. For this privilege the inventor would provide the university an ownership stake in any returns to the invention. The inventor would be free to contract with the university TLO or any other entity that might assist in commercialization. The second alternative is to make all inventions immediately publicly available through a public domain strategy or, through a requirement that all inventions be licensed non-exclusively. Both alternatives would address the current dysfunctional arrangements in university technology commercialization. 相似文献

This paper analyses the causality between inventor productivity and inventor mobility. The results show that the level of education has no influence on inventor productivity. Making use of external sources of knowledge, on the contrary, has a significant effect on productivity. Finally, firm size has a positive impact on productivity. Firm size also influences inventor mobility, although negatively. Whereas existing research implicitly assumes causality to point in one direction, this study ex ante allows for a simultaneous relationship. To deal with the expected endogeneity problem, instrumental variables techniques (IVREG and IVPROBIT) will be employed. Results show that mobile inventors are more productive than non-movers. Whereas a move increases productivity, an increase in productivity decreases the probability to observe a move. 相似文献

Based on a survey of the inventors of 9017 European patented inventions, this paper provides new information about the characteristics of European inventors, the sources of their knowledge, the importance of formal and informal collaborations, the motivations to invent, and the actual use and economic value of the patents. 相似文献

Benefiting colleagues but not the city: Localized effects from the relocation of superstar inventors
Paolo Zacchia 《Research Policy》2018,47(5):992-1005
In this paper I examine episodes in which superstar inventors relocate to a new city. In particular, in order to assess whether the beneficial effects of physical proximity to a superstar have a restricted network dimension or a wider spatial breadth (spillovers), I estimate changes in patterns of patenting activity following these events for two different groups of inventors: the superstar's close collaborators, and all the other inventors in a given urban area, for both the locality where the superstar moves to and for the one that is left behind. In the case of collaborators, I restrict the attention to patents realized independently from the superstar. The results from the event study register a large and persistent positive effect on the collaborators in the city of destination, as well as a simultaneous negative trend affecting those still residing in the previous location. In the long run, these effects translate into an increased difference between the two groups of about 0.16 patents per inventor. Conversely, no city-wide spillover effect can be attested, offering little support to place-based policies aimed at inducing a positive influx of top innovators in urban areas. 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
