    Abstract: We compare patent litigation cases across four European jurisdictions – Germany, France, the Netherlands, and the UK – covering cases filed during the period 2000-2008. For our analysis, we assemble a new dataset that contains detailed information at the case, litigant, and patent level for patent cases filed at the major courts in the four jurisdictions. We find substantial differences across jurisdictions in terms of case loads. Courts in Germany hear by far the largest number of cases in absolute terms, but also when taking country size into account. We also find important between-country differences in terms of outcomes, the share of cases that is appealed, as well as the characteristics of litigants and litigated patents. A considerable number of patents are litigated in multiple jurisdictions, but the majority of patents are subject to litigation only in one of the four jurisdictions.

    Abstract: It has long been argued that geographic co-location supports knowledge spillovers. More recently, this argument has been challenged by showing that knowledge spillovers mainly flow through social networks, which may or may not be localized at various geographic scales. We further scrutinize the conjecture of geographically bounded knowledge spillovers by focusing on knowledge flows between academia and industry. Looking into citations to non-patent literature (NPL) in 2,385 Dutch polymer patents, we find that citation lags are shorter on average if Dutch rather than foreign NPLs are cited. However, when excluding individual and organizational self-citations, geographically proximate NPLs no longer diffuse faster than foreign NPLs. This suggests that knowledge is not “in the air” but transferred by mobile individuals and/or direct university-industry collaboration. Our findings moreover suggest an important role of international conferences in the diffusion of recent scientific knowledge.

    Abstract: Innovation processes under patent protection generate hold-up problems if complementary patents are owned by different firms. We show that in line with Hart and Moore (1990), shareholder ownership overlap across firms with patent complementarities helps mitigate such hold-up problems and correlates significantly with higher patent investment and more patent success as measured by future citations. The positive innovation effect is strongest for concentrated overlapping ownership and for the cases when the overlapping shareholders are dedicated investors.
    Keywords: hold-up problems; innovation; institutional ownership; patents

    Abstract: This study aims to analyze the development of intangible assets in Turkey for the period of 2005-2013 by using Borsa Istanbul (BIST) database. There has not been any study dealing with intangible assets and their role in the economic growth or firm productivity in Turkey due to the lack of data and classification in this field. In this study, we apply the classification introduced by Corrado et al. (2004) to fill this research gap in the literature. According to this, intangible assets could be decomposed into three parts namely, economic competency, innovative property, andcomputerized information and database. Economic competency is comprised of advances given, comptation agreements, and special costs. Computerised information and database, on the other hand, is closely related to computer software, information systems, computer programs, and customer database. Innovative property includes assets such as patents, licenses, films, and research and development activities. According to our results, the share of intangible assets in the economy is less than that of tangible assets. The evidence, however, suggests that the share of intangibles tends to increase in recent years. As far as the subcomponents of intangible assets are considered, the share of innovative property in total assets is much higher than the share of other subcomponents. The share of computerised information and database, on the other hand, is expected to increase in following years.
    Keywords: Intangible assets, Turkey, BIST XUTUM.
