    This exploratory study looks at the structural and geographical patterns of corporate knowledge flows from a regional perspective. The methodological approach combines the centrality indicators developed in the social network analysis (SNA) and complementary tools from the graphs theory to assess the betweenness centrality of regions (or poles)ƒ{ their ability to control knowledge flows within a network or to impact its cohesivenessƒ{ and the relative contribution of individual firms (or layers) to the centrality of regions. The combination of the two approaches brings relevant insights on the way large R&D-driven firms organise their knowledge sourcing and generation across world regions.

    SUPERCEDES EORKING PAPER 17-32 Buzard et al. (2017) show that American R&D labs are highly spatially concentrated even within a given metropolitan area. We argue that the geography of their clusters is better suited for studying knowledge spillovers than are states, metropolitan areas, or other political or administrative boundaries that have predominantly been used in previous studies. In this paper, we assign patents and citations to these newly defined clusters of R&D labs. Our tests show that the localization of knowledge spillovers, as measured via patent citations, is strongest at small spatial scales and diminishes with distance. On average, patents within a cluster are about two to four times more likely to cite an inventor in the same cluster than one in a control group. Of import, we find that the degree of localization of knowledge spillovers will be understated in samples based on metropolitan area definitions compared to samples based on the R&D clusters. At the same time, the strength of knowledge spillovers varies widely between clusters. The results are robust to the specification of patent technological categories, the method of citation matching, and alternate cluster definitions

    We analyze the technology sovereignty of Europe, the US, China, Japan, and Korea, representing the world's leading innovators. By examining citations from the universe of PCT patent applications between 2000 and 2020, we determine the strength and direction of inventions' influence at global and bilateral levels to assess each geographic area's technology sovereignty. The US shows superior technology sovereignty through its leadership in global and bilateral influence. While the US and Europe are highly integrated, their global positions differ as Europe depends on all geographic areas except China. Although China has filed the most patent applications in recent years, bilaterally it remains dependent on all other geographic areas. Moreover, only Japan and Korea show a recent decline in their global influence, despite previously holding a leading position.

    Does the emigration of skilled individuals necessarily result in losses for source countries due to the brain drain? Combining industry-level patenting and migration data from 32 European countries, we show that emigration in fact positively contributes to innovation in source countries. We use changes in the labour mobility legislation within Europe as exogenous variation to establish causality. By analysing patent citation data, we further provide evidence that these positive effects are driven by knowledge flows that are triggered by emigrants. While skilled migrants are not inventing in their home country anymore, they contribute to cross-border knowledge and technology diffusion and thus help less advanced countries to catch up to the technology frontier.

    We analyze the duration of the patent examination process at the European Patent Office (EPO). Our data contain information related to the patent's economic and technical relevance, EPO capacity and workload as well as novel citation measures which are derived from the EPO's search reports. In our multivariate analysis we estimate competing risk specifications in order to characterize differences in the processes leading to a withdrawal of the application by the applicant, a refusal of the patent grant by the examiner or an actual patent grant. Highly cited applications are approved faster by the EPO than less important ones, but they are also withdrawn less quickly by the applicant. The process duration increases for all outcomes with the application's complexity, originality, number of references (backward citations) in the search report and with the EPO's workload at the filing date. Endogenous applicant behavior becomes apparent in other results: more controversial claims lead to slower grants, but faster withdrawals, while relatively well-documented applications (identified by a high share of applicant references appearing in the search report) are approved faster and take longer to be withdrawn.

    The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to non-localized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of EP patent applications. Analyzing patterns of knowledge flows captured in patent citations we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization we conclude that having access to a knowledge repository compensates for localization disadvantages.
