Abstract:
Over the last few years, worldwide mergers and acquisitions (M&A) have increased sharply both in terms of value and volume. This development has not only been driven by corporate inquirers but also to an increasing extent by private equity investors. In this paper, we analyze differences in acquisition motives for corporate and private equity investors. We pay particular attention to the importance of technological assets in M&A transactions and distinguish between the technological value of patents and their potential to block competitors in technology markets. Our empirical results for European firm acquisitions in the period from 1999 to 2003 show that both corporate and private equity investors pay a higher price for target firms with valuable patents. However, patents with a potential to block technology competitors seem to be only of interest to corporate investors, especially if these are closely related to the patent portfolio of the inquirer.

Abstract:
This paper analyzes the effects of public R&D funding on R&D expenditure and patenting behavior of German firms. The main focus is the direct impact of subsidies on R&D and the indirect effect on innovation output measured by patent applications. We distinguish the productivity of purely privately financed R&D and additional R&D induced by public incentive schemes. For this, a treatment effects analysis is conducted in a first step. The results are implemented into the estimation of a patent production function. It turns out that both purely privately financed R&D and publicly induced R&D show a positive productivity.

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 tests some of the predictions of recent advances in trade theory that have focused on different trade patterns of firms within the same sector. Helpman, Melitz and Yeaple (2005) develop a model in which innate productivity differences between firms determine the degree of international engagement of firms: The least productive firms produce for the domestic market, better performers engage in export activities, and the top firms establish foreign subsidiaries. Using German firm-level data from 1996 to 2002, we test this prediction using non-parametric methods, by examining the distribution functions of the three subsets of firms for stochastic dominance. Rather than just comparing first moments, this technique allows us to compare productivity over the entire distribution. Our results show robust support for the prediction from theory.

Abstract:
Gaining access to technological assets and patents, in particular, has long been a major motive and objective for firm acquisitions. On the one hand, patents are used as a building instrument for the acquirer's technology portfolio. On the other hand, patents can be attractive because of their strategic value as a bargaining chip, e.g. in licensing negotiations. This is especially the case if patents have the potential to block competitors. Drawing on transaction cost economics and the resource-based view of the firm, we analyze the importance of these two faces of technology acquisition for the valuation of a target firm. Empirical evidence for European firm acquisitions in the period from 1999 to 2003 indicates that the price paid by an acquirer for a target increases with the patent stock, the relatedness, the value and the blocking potential of the target's patents, especially if blocking patents are in technology fields related to the acquiring firm's patent portfolio. Our results have implications for competition authorities, in that M&A transactions may considerably impact technology markets. This would also need to be reflected in the management's technology strategy.

Abstract:
Mergers and acquisitions (M&As) constitute a disruption to the working environment of the inventive labor force of the acquired company. If inventors would respond with a decline of their patent productivity or departure from the firm this can be detrimental to the innovative process within the merged entity and can be contradictory to the aims of the firm acquisition. This paper provides empirical evidence on post-merger mobility and productivity of 673 inventors employed by European acquisition targets in the years 2000 and 2001. The empirical results show that 1.) the most productive and experienced individuals stay with the merged entity; 2.) inventors that left the acquired firm are less productive in post-merger years than those that stayed with the merged entity; 3.) M&As trigger inventor mobility, but do not lead to a decline in patent productivity if compared to a control group of inventors that have not been involved in a firm acquisition.

Abstract:
The knowledge produced by academic scientists has been identified as a potential key driver of technological progress. Recent policies in Europe aim at increasing commercially orientated activities in academe. Based on a sample of German scientists across all fields of science we investigate the importance of academic patenting. Our findings suggest that academic involvement in patenting results in greater knowledge externalities, as academic patents appear to generate more forward citations. We also find that in the European context of changing research objectives and funding sources since the mid-90's, the "importance" of academic patents declines over time. We show that academic entrants have patents of lower "quality" than academic incumbents but they did not cause the decline, since the relative importance of patents involving academics with an existing patenting history declined over time as well. Moreover, a preliminary evaluation of the effects of the abolishment of the "professor privilege" (the German counterpart of the U.S. Bayh-Dole Act) reveals that this legal disposition led to an acceleration of this apparent decline.

Abstract:
Against the background of the so-called “European paradox”, i.e. the conjecture that EU countries lack the capability to transfer science into commercial innovations, knowledge transfer from academia to industry has been a central issue in policy debates recently. Based on a sample of German scientists we investigate which academic inventions are patented by a scientific assignee and which are owned by corporate entities. Our findings suggest that faculty patents assigned to corporations exhibit a higher short-term value in terms of forward citations and a higher potential to block property rights of competitors. Faculty patents assigned to academic inventors or to public research institutions, in contrast, are more complex, more basic and have stronger links to science. These results may suggest that European firms lack the absorptive capacity to identify and exploit academic inventions that are further away from market applications.

Abstract:
In recent years, firms have increasingly contributed to and been confronted with a patent landscape characterized by numerous but marginal inventions, overlapping claims and patent fences. Literature suggests that both the fragmentation of ownership and the threat of a firm's patent applications being blocked by competitors' patents lead to increased patenting and inlicensing activity. In this paper, we investigate the effect of expected blocking on firms' engagement in in- and out-licensing. Based on a sample of more than 400 German manufacturing firms our results show that firms engage in in- and out-licensing if technology competition increases which is in line with the argument that licensing can mitigate hold-up problems in technology markets.

Abstract:
While often presumed in academic literature and policy discussions there is little empirical evidence showing that academic patents protect more basic inventions than corporate patents. This study provides new evidence on the basicness of academic patents using German professor patents linked to patent opposition data from the European Patent Office (EPO). Patent oppositions are the most important mechanism by which the validity of patents filed at the EPO can be challenged. Controlling for patent value, asymmetric information and diverging expectations between the opposition parties, the likelihood of a potentially litigious situation and the relative costs of opposition versus settlement, we find that academic patents are opposed less frequently than a control group of corporate patents. This suggests that academic patents cover rather basic inventions with a low immediate commercial value not threatening current returns of potential plaintiffs. The effect is weaker for academic patents filed in collaboration with the business sector, which suggests that those patents are evaluated as more applied by owners of potentially rival technologies.

Abstract:
This paper empirically investigates a sample of German domestic merger and acquisitions (M&As) in the 1990s to analyze the importance of a related technology portfolio in the decision to acquire a particular firm. The novelty of this analysis lies in the fact that the sample does not contain exclusively large firms, but also a large share of small and medium-sized entrprises (SMEs). The empirical results suggest that firms engage in M&As to strengthen their technological competencies. A related technology portfolio is, in particular, important for the decision to acquire SMEs. This suggests an information advantage of acquirers with related technologies.

Abstract:
The growing importance of technology relevant non-publication output of university research has come into the focus of policy-makers' interest. A fierce debate arose on possible negative consequences of the increasing commercialization of science, as it may come along with a reduction in research performance. This paper investigates the relationship between publishing as a measure of scientific output and patenting for German professors active in a range of science fields. We combine bibliometric/technometric indicators and econometric techniques to show that patenting positively correlates with the publication output and with publication quality of patenting researchers.

Abstract:
The increasing commercialization of university discoveries has initiated a controversy on the impacts for future scientific research. It has been argued that an increasing orientation towards commercialization may have a negative impact on more fundamental research efforts in science. Several scholars have therefore analyzed the relationship between publication and patenting activity of university researchers, and most articles report positive correlations. However, most studies do not account for heterogeneity of patenting activities ranging from university patents to corporate patents. While the former may have closer links to basic research, this is not what we expect from the latter. We argue that such efforts will indeed distract scientists from other activities, as collaborations with companies are usually assumed to have an applied character and do not necessarily coincide with basic research tasks. This paper investigates the incidence of patenting and publishing distinguishing between different types of patents for a large sample of professors active in Germany. Our results show that, while university patents as well as patents assigned to not-for-profit institutions complement publication quantity and quality, corporate patents yield negative effects.

Abstract:
This paper investigates the motive of pre-empting technology competition through mergers and acquisitions (M&A). Exploiting the patent application procedure at the European Patent Office we introduce a new measure for the possibility to create entry barriers in technology markets. Our results show significant evidence that firms engage in horizontal M&A to pre-empt competition in technology markets.

Abstract:
Merger and acquisitions (M&As) have been an important tool for reorganizing the European market since the establishment of European Economic and Monetary Union. This paper suggests that European integration helped and encouraged European firms to source technology across national borders in Europe, establishing European innovative firms. The figures confirm that, once barriers impeding the free movement of capital, goods and labor had fallen, European firms used M&As intensively to enter foreign European markets. Enhancing technology competencies is found to be one of the main motives for cross-border acquisitions in the 1990s but is not a factor in domestic acquisitions over the same period.

Abstract:
In the 1990s, patenting schemes changed in many respects: Upcoming new technologies accelerated the shift from price competition towards competition based on technical inventions, a worldwide surge in patenting took place, and the 'patent thicket' arose as a consequence of strategic patenting. This study analyzes the importance of patenting versus secrecy as an effective alternative to protect intellectual property in the inventions' market phase. The sales figure with new products is introduced as a new measure of the importance of IP protection tools among product innovating firms. Focusing on German manufacturing in 2000, it turns out that patents are an effective means to protect intellectual property in the market, whereas secrecy seems to be rather important for inventions that are not yet commercialized.

Abstract:
This paper examines the causal relationship between productivity and exporting in German manufacturing. We find a causal link from high productivity to presence in foreign markets, as postulated by a recent literature on international trade with heterogeneous firms. We apply a matching technique in order to analyze whether the presence in international markets enables firms to achieve further productivity improvements, without finding significant evidence for this. We conclude that high-productivity firms self-select themselves into export markets, while exporting itself does not play a significant role for the productivity of German firms.

Abstract:
This paper analyzes the effect of public R&D subsidies on firms' private R&D investment per employee and new product sales in German manufacturing. Parametric and semiparametric two-step selection models are applied to this evaluation problem. The results show that the average treatment effect on the treated firms' R&D intensity is positive. The estimated effects are robust with respect to the different selection models. Further results show that publicly induced R&D spending is as productive as private R&D investment in generating new product sales.
