    Abstract: This paper examines the effects of regional R&D on patenting for Sweden within an accessibility framework. We use two measures of patenting: number of patents granted per capita and a composite of quality-adjusted patents which we regard as an innovation indicator, respectively. Three conclusions emerge. First, we find that the specification where innovations per capita is used as a dependent variable performs much better than with granted patents per capita for capturing relationships with regional R&D. In fact, quantile regressions over the distribution of different patenting and innovation levels per capita show that R&D efforts within regions affect innovations per capita positively, except for the regions with the lowest levels of R&D. The effects on granted patents per capita are less robust and depend inconsistently on the level of R&D. Secondly, accessibility to inter-regional R&D do not affect innovation significantly in our results, which suggests that effects are locally bounded. This implies that studies of the R&D-innovation relationship are plagued by misspecification, since studies tend to show that R&D-effects diffuse to other regions. This is also the case in our study; the inter-regional effects are an important factor for granted patents. Third, the share of university R&D of all regional R&D has no effect on patenting, which suggests that the two types of R&D are substitutes. In view of these results the recommendation must be to use quality-adjusted patents for regional innovation studies rather than patent grants.

  2. By: Alberto Galasso; Mark Schankerman
    Abstract: We study how fragmentation of patent rights ('patent thickets') and the formation of theCourt of Appeal for the Federal Circuit (CAFC) affected the duration of patent disputes, andthus the speed of technology diffusion through licensing. We develop a model of patentlitigation which predicts faster settlement agreements when patent rights are fragmented andwhen there is less uncertainty about court outcomes, as was associated with the 'pro-patentshift' of CAFC. The model also predicts that the impact of fragmentation on settlementduration should be smaller under CAFC. We confirm these predictions empirically using adataset that covers nearly all patent suits in U.S. federal district courts during the period1975-2000. Finally, we analyze how fragmentation affects total settlement delay, taking intoaccount both reduction in duration per dispute and the increase in the number of requiredpatent negotiations associated with patent thickets.

    Abstract: Relying on a comprehensive dataset including detailed information on all patent applications filed to the EPO from 1980 to 2000 and on the renewal of those of them that were granted, this paper presents the first survival time analysis of the determinants of patent length. The results are threefold: first, they clearly establish that the life expectancy of patent rights has significantly increased over the past decades despite a small decline in the average grant rate. Second, they show that some filing strategies strongly influence the length of patents, possibly due to induced delays in the examination process. And third, they confirm that more valuable patents (more cited or covering a larger geographical scope) tend to live longer.

    Abstract: It is a common perception that European public-funded research fails to commercialize their discoveries, in contrast to the perceived success of their American counterparts. This resulted in policies aimed at improving the commercialization of European publicly-funded research, including the establishment of Technology Transfer Offices (TTOs). Recent surveys on the activities of these TTOs show that although European public-funded research lags behind the United States in patent applications and grants, they produce more start-ups, and have comparable results for the number of licenses executed. Steps to improve the international comparability of TTO surveys could provide useful new indicators for policy development. However, this will also require indicators for knowledge transfer through informal 'open science' methods.

  5. By: Aschhoff, Birgit; Sofka, Wolfgang
    Abstract: Valuable knowledge emerges increasingly outside of firm boundaries, in particular in public research institutions and universities. The question is how firms organize their interactions with universities effectively to acquire knowledge and apply it successfully. Literature has so far largely ignored that firms may combine different types of interactions with universities for optimizing these knowledge sourcing strategies. We argue conceptually that firms need diverse (broad) and highly developed (deep) combinations of various interactions with universities to maximize returns from these linkages. Our empirical investigation rests upon a survey of more than 800 firms in Germany. We find that both the diversity and intensity of interactions with universities propel innovation success. However, broadening the spectrum of interactions is more beneficial with regard to innovation success. In an exploratory step we go beyond breadth and depth of interactions by identifying four distinct patterns of interaction. Our findings show that formal forms of interaction (joint/contract) research provide the best balance between joint knowledge development and value capture.

  6. By: Tom-Reiel Heggedal (Statistics Norway)
    Abstract: An important policy question is whether research and development (R&D) in new, emerging technologies should be more subsidized than R&D in other more mature technologies. In this paper I analyze if innovation externalities caused by knowledge spillovers from private firms may warrant a differentiated R&D policy. I find that R&D in emerging and mature technologies should not be subsidized equally. The reason is that R&D in the two technologies is not equally undersupplied in the market due to differences in their knowledge stocks. R&D in the mature technology should be subsidized more when the sum of the output elasticities with respect to labor and knowledge in R&D production is high, while R&D in the emerging technology should be subsidized more when the elasticities are low.

    Abstract: Firms compete increasingly in an open innovation environment. Search strategies for external knowledge become therefore crucial for firm success. Existing research differentiates between the breadth (diversity) and depth (intensity) with which firms pursue external knowledge source. A consensus exists that resource constrains force firms to balance both dimensions. However, relatively little is known on how managers can selectively strengthen one of these dimensions. We argue conceptually that the breadth and depth of a search strategy depends upon the nature of a firm’s absorptive capacity (i.e. whether they are built through internal or external R&D activities) and the munificence of its innovation environment. We test these hypotheses empirically for a large sample of more than 8,300 firms from 12 European countries. Our empirical results show that in-house R&D strengthens the depth of a firm’s search strategy while external R&D activities (e.g. contract research) increase its breadth. Moreover, we find that scarce innovation environments favor deep search strategies while breadth is more prevalent in munificent environments. We develop targeted management recommendations based on these results.

  8. By: Grimpe, Christoph; Hussinger, Katrin
    Abstract: Literature has identified formal and informal channels in university technology transfer. While formal technology transfer typically involves a legal contract on a patent or on collaborative research activities, informal transfer channels refer to personal contacts and hence to the tacit dimension of knowledge transfer. Research is, however, scarce regarding the interaction of formal and informal transfer mechanisms. In this paper, we analyze whether these activities are mutually reinforcing, i.e. complementary. Our analysis is based on a comprehensive dataset of more than 2,000 German manufacturing firms. We perform direct and indirect tests for the complementarity of formal and informal technology transfer. Our results confirm a complementary relationship: using both transfer channels contributes to higher innovation performance. The management of the firm should therefore strive to maintain close informal relationships with universities to realize the full potential of formal technology transfer.

    Abstract: This paper studies the role of intrinsic motivation, reputation and reciprocity in driving opensource software innovation. We exploit the observed pattern of contributions - the 'revealedpreference' of developers - to infer the underlying incentives. Using detailed information oncode contributions and project membership, we classify developers into distinct groups andstudy how contributions from each developer type vary by license (contract) type and otherproject characteristics. The central empirical finding is that developers strongly sort bylicense type, project size and corporate sponsorship. This evidence confirms the importanceof heterogeneous motivations, specifically a key role for motivated agents and reputation, butless for reciprocity.

    Abstract: In this paper I differentiate between two types of benefits of open innova- tion. Network externalities e¤ect happens when open innovation increases the participation of one group of users which increases the value of adoption for another group of users. Learning e¤ect happens when economic actors increase their knowledge through access to external sources of knowledge. I investigate how each effect can be dominant depending on nature of products, by drawing upon previous research in product modularity. In addition I discuss the fac- tors which will strengthen or weaken the e¤ects of each dimension. The main variables which influence learning are, tacitness of knowledge, technological op- portunities, appropriability of knowledge and turbulence. Network externalities e¤ect can be strengthened by increased user innovation.

    Abstract: Research and development (R&D) in the field of nanomaterials is expected to be a major driver of innovation and economic growth. In this respect, many countries, as national systems of innovation, have established support programs offering subsidies for industry- and government-funded R&D. Consequently, it is of great interest to understand which factors facilitate the creation of new technological knowledge. The existing literature has typically addressed this question by employing a knowledge production function based on firm-, regional- or even country-level data. Estimating the effects for the entire national system of innovation, however, implicitly assumes poolability of regional data. We apply our reasoning to Germany, which has well-known – and wide – regional disparities, for example between the former East and West. Based on analyses at the level of NUTS-3 regions, we find different knowledge production functions for the East and the West. Moreover, we investigate how our results are affected by the adoption of alternative aggregation levels. Our findings have implications for further research in the field, that is, a careful evaluation of poolability and aggregation is required before estimating knowledge production functions at the regional level. Policy considerations are offered as well.
