    Abstract: Patents and their renewals are critical because they protect inventions and reinforce information reported to investors about the utility and the quality of inventions. Thus, they signal the appropriate use of financial resources being invested, notably

    Abstract: Cumulative innovation is central to economic growth. Do patent rights facilitate or impede follow-on innovation? We study the causal effect of removing patent rights by court invalidation on subsequent research related to the focal patent, as measured by later citations. We exploit random allocation of judges at the U.S. Court of Appeals for the Federal Circuit to control for endogeneity of patent invalidation. Patent invalidation leads to a 50 percent increase in citations to the focal patent, on average, but the impact is heterogeneous and depends on characteristics of the bargaining environment. Patent rights block downstream innovation in computers, electronics and medical instruments, but not in drugs, chemicals or mechanical technologies. Moreover, the effect is entirely driven by invalidation of patents owned by large patentees that triggers more follow-on innovation by small firms.

    Abstract: In this paper, we introduce into a Schumpeterian growth model an inventive step: a minimum innovation size required for patents, which is a patentability requirement. We show that each R&D firm targets only the industries that the incumbentfs technology is sufficiently obsolete in order to satisfy an inventive step requirement. This is because a technological gap between innovator and incumbent is larger in the industries that use older technology. Under the circumstance, strengthening an inventive step requirement reduces the industries targeted by R&D, on the other hand, increases R&D investments to the targeted industries. Consequently, we find a nonmonotonic effect of the inventive step on the aggregate flow of innovations.

    Abstract: Measuring innovation activities involves critical decisions in selecting appropriate indicators and levels of observation. The present article contributes to the literature on this subject by addressing innovation measurement on the regional level. The dimensionality of regional innovation is examined by applying a principal component analysis on seven innovation output indicators in European regions from the Community Innovation Survey and two traditional indicators, i.e. patent applications and R&D expenses. The analysis reveals that regional innovation indeed needs to be regarded as a multidimensional concept involving technological, commercial and service innovation. These distinct innovation activities exhibit clear regional patterns with both technological and service innovation concentrated in highly developed territories and urban areas displaying particularly strong innovation performance in services. In addition, commercially successful innovation appears clustered in backward regions and may thus be seen as imitation efforts and technology transfers from areas at the innovation frontier. Overall, the elaborated findings suggest that the selection of innovation indicators in empirical analyses demands appropriate motivation and theoretical guidance.
    Keywords: regional innovation, innovation dimensions, Principal Component Analysis, patent applications, Community Innovation Survey

    Abstract: In this paper we propose an innovative methodology that aims to solve drawbacks related to how patent data are allocated and organized in international databases. We propose as a case study the biofuels sector, in order to evaluate the validity of such a method. Starting with a systematic mapping of biofuels production value chain, we have built a comprehensive description of the biofuels technological domain. The resulting list of keywords relies on an iterative selection approach, based on an analysis of recent scientific literature combined with the keyword search tool developed by Scopus. The final patent database, BioPat, has been finalized by a validation procedure with the help of expert interviews, revealing improved accuracy compared with standard IPC-based codes. Collected information in BioPat allows us to derive more intriguing insights on the characteristics and evolution of technological patterns in the biofuels sector with respect to standard classification methods.
    Keywords: patents classification, keyword selection, innovation patterns, liquid biofuels, knowledge complexity.

    Abstract: This paper examines the behavioural finance aspects of developed countries which invest significantly in R&D, while trying to benefit from this investment, within the framework of the so called ‘creative intelligence’. At this level, creative intellige
