Effects of Patent Policy on Outputs and Commercialization of Academic Patents in China: A Spatial Difference-in-Differences Analysis

The development of a difference-in-differences estimator is a new move in patent policy evaluation research. However, such an estimator neglects the possibility that academic patent activities follow a spatial autoregressive process with respect to the dependent variable. The objective of this study was to propose a spatial difference-in-differences estimator accounting for possible spatial spillover effects. In this study, an empirical analysis of a sample of 31 Chinese provinces from 2010 to 2019 indicates that an incentive patent policy has a positive impact on the output and commercialization of academic patents, with positive effects also spilling over into neighboring provinces. This study further found that incentive patent policies play a placebo role in academic patent activities. Provincial patent policies are merely a proxy for other variables that characterize the systemic differences between provinces that implement patent policies and those that do not. Therefore, the promotion of academic patent activities cannot be attributed to policy incentives.

The development trend and academic patent technology network of laser and optical technologies

Purpose The application of laser and optical technologies in the industry is wide and extensive; the development and application of laser and optical technologies have become a promising research domain. However, most existing studies have focused on the technical aspects or the application aspects; these studies have not highlighted the technology distribution and application development of laser and optical technologies from the big picture. Additionally, the manner in which the research and development (R&D) results of universities correspond to the needs of enterprises and industry has become a topic of concern for the public. Therefore, this study aims to adopt the academic patents as the basis for analysis and to construct a laser and optical technology network. Design/methodology/approach Therefore, in the current study, the researchers have analyzed relevant academic patent technology networks, using academic patents of laser and optical technologies as a basis of analysis. Findings The study results indicated that the key technologies mainly lie in nanostructures, metal-working, material analysis and semiconductor devices. Additionally, these technologies are mainly applied in industries, such as optics, medical technology, pharmaceuticals, biotechnology and organic fine chemistry; this indicated that a large proportion of academia’s R&D outcomes are applied in these industries. Originality/value In this study, the researchers have constructed a technology network model to explore the technical development direction of laser and optical technologies; the results of the current study could serve as a reference for universities and industry for allocation of R&D resources.

Technological structure network analysis to explore the hotspots of academic patents in international technology transfer

International technology transfer is a determinant of a country’s national revenue and economic growth. Technology exported through international technology transfer can be the factor that gives a country a competitive edge. Therefore, investigation of international technology transfer has become essential. With the role of universities in innovation changing, academic patents have increased significantly over the past 10 years. Thus, this study used academic patents involved in international technology transfer as a basis for analysis and attempted to identify technological hotspots through a technological structure network analysis. The results indicated that key technologies in academic patent–based international technology transfer networks were mainly concentrated on measurement, nanotechnology, medical technology, biotechnology, and electric digital data processing. An academic patent technological hotspot network model was established to serve as a reference for academic technology transfers as well as for governments in their promotion of emerging technologies.

Do company-owned academic patents influence firm performance? Evidence from the Italian industry

We document that firms holding academic patents in their portfolios perform better in terms of market power since they benefit from academic knowledge spillovers generated by academic patents. On the other hand, we detect a negative effect on firms’ short-term profitability imputable to a larger fixed cost associated to the acquisition and exploitation of these patents. In terms of policy, our analysis suggests focusing on company-owned academic patents. A set of economic incentives dedicated to university–industry knowledge transfer through academic patents could support integration between basic and applied research.

Misallocation of scientific credit: the role of hierarchy and preferences. An extension of Lissoni et al. (2013)

We extend the results in Lissoni et al. (2013, J. Econ. Behav. Organ., 95, 49–69) on scientific credit misallocation, as measured by misalignment between authorship and inventorship recognition in patent-publication pairs. Extending the analysis to European data, we confirm that, other things being equal, the probability of exclusion of a scientific author from a publication-related patent declines with seniority and increases for women. In addition, we find that the senior scientists’ power to exclude other authors plays a more important role in explaining the patterns of exclusion than differences in authors’ attribution preferences. The unfavorable treatment of young and/or female scientists emerges in particular when patents are owned by companies or individuals, thus providing a warning flag on those institutional arrangements that favor company or individual ownership of academic patents.

Academic spill-ins or spill-outs? Examining knowledge spillovers of university patents

In this article, we investigate whether academic technology-based knowledge crosses university boundaries or remains trapped inside the ivory tower. To do so, we rely on a matched sample approach to compare the spillovers generated by academic and firm patents using measures that take into account knowledge spilling-in and knowledge spilling-out of academia. Although it is true that knowledge exchanges among universities may inflate the overall spillovers of university patents vis-à-vis firm patents, our results indicate that university patents generate more spillovers than a comparable sample of matched corporate patents, even when knowledge flows among universities are not regarded as spillovers. This suggests that, in our sample, firm technologies more frequently rely on academic patents than on technologies from other corporations. In addition, we find that the gap between university and industry spillovers differs across industries, with industries where patents are important for appropriating returns from R&D (i.e. more economically valuable), such as drugs, presenting a smaller gap than in industries with complex technologies (where firms have strong incentives to patent aggressively), such as computers. Finally, we show that industry patents generate more spillovers locally and that academic knowledge spillovers are less geographically localized than those of corporate research.

Academic patenting in Brazil: the role of academic inventors in PCT patent applications – 2002-2012

Purpose The purpose of this paper is to analyse the patenting activity of the Brazilian academic sector vis-à-vis the domestic business sector, taking into account the recent evolution of Brazil’s industrial policies. The paper differentiates between “university academic patents”, which are owned by the universities, and “non-university academic patents”, which despite being invented by academic staff are not owned by the universities. Design/methodology/approach The authors’ cross-checked information regarding the names of all inventors with Brazilian addresses in PCT patent applications in the Espacenet database with the names of researchers in the CVs available on the Lattes Platform of CNPq. The analysis specifically focussed on patent applications published in the PCT with Brazilian priority for the 2002-2012 period. Findings It was found that the Brazilian academic patents concentrate on science-based technology areas, especially in the Pharma Biotechnology domain. For a total of 466 patent applications with Brazilian priority in this field, 233 have academic inventors. Of those 233 academic applications, 66.1 per cent have universities as their owners, while the remaining 33.9 per cent are not owned by universities. Further, it was found that there are more Brazilian academic patents in the biotechnology sub-domain than those filed by the business sector. Research limitations/implications This research was based on the intersection of patent databases and the content available on the official curriculum base of Brazil (Lattes Platform, CNPq). Once the curricula information are voluntary, there are risks inherent reliability of this information. Practical implications This study allows us to identify more accurately which is the effective role of the Brazilian Academy in patents generation, revealing that a significant unaccounted deposits with personal inventors or companies’ ownership really have a academic contribution. Originality/value This paper shows that the academic sector plays a key role in Brazil’s international patenting activity, particularly in science-intensive technology domains, and it highlights the specific contribution of academic patents not owned by universities.
