We propose an empirical strategy to estimate competition in innovation markets. Our method relates firms’ market return on equity to information about patent citation patterns. Two innovations are implemented in the methodology. First is the application of daily abnormal stock returns rather than annual measures of Tobin's q. Second is the creation of citation patterns related to the area of science a firm patents in as represented by the detailed patent classification system. We find that markets positively reward firms when patents are granted. We further find that firm's market value increases when its patent portfolio is cited. We find evidence of competition in innovation markets. The market reacts at the time that the citation occurs and does not anticipate future citations at the time of patenting. Holding this effect constant, we find that citations from patents in the same area of science tend to reduce market value. We interpret these findings as consistent with more citations indicating more valuable intellectual property but citations from competing technologies decreasing it.  相似文献

Patents and the survival of Internet-related IPOs   总被引:4,自引:0,他引:4  
We examine the effect of patenting on the survival prospects of 356 Internet-related firms that made an initial public offering on the NASDAQ at the height of the stock market bubble of the late 1990s. By March 2005, almost 2/3 of these firms had delisted from the exchange. Changes in the legal environment in the US in the 1990s made it much easier to obtain patents on software, and ultimately, on business methods, though less than 1/2 of the firms in our sample obtained, or attempted to obtain, patents. For those that did, we hypothesize that patents conferred competitive advantages that translate into higher probability of survival, though they may also simply be a signal of firm quality. Controlling for other determinants of firm survival, patenting is positively associated with survival. Quite different processes appear to govern exit via acquisition compared to exit via delisting from the exchange due to business failure. Firms that applied for more patents were less likely to be acquired, though if they obtain unusually highly cited patents they may be a more attractive acquisition target. These findings do generally not hold true for “business method” patents, which do not appear to confer a survival advantage.  相似文献

Business cycles modify firms’ incentives to innovate and the direction of innovation. By introducing a new measure of patent unconventionality this paper explores the impact of the business cycle on firms’ technological search strategies. We find that during upturns firms generate inventions characterized by a higher level of technological unconventionality. We also find that financially resilient and diversified firms produce more unconventional patents. While patent unconventionality is associated with technological impact and market value, firms extract more value by investing in unconventional inventions in downturns.  相似文献

This paper presents a synthetic framework identifying the central drivers of start-up commercialization strategy and the implications of these drivers for industrial dynamics. We link strategy to the commercialization environment—the microeconomic and strategic conditions facing a firm that is translating an “idea” into a value proposition for customers. The framework addresses why technology entrepreneurs in some environments undermine established firms, while others cooperate with incumbents and reinforce existing market power. Our analysis suggests that competitive interaction between start-up innovators and established firms depends on the presence or absence of a “market for ideas”. By focusing on the operating requirements, efficiency, and institutions associated with markets for ideas, this framework holds several implications for the management of high-technology entrepreneurial firms.  相似文献

Research and development (R&D) is often essential for firms’ profitability and growth. At the same time, R&D is long-term and risky. We show that innovation activities lead to information ambiguity about the future value of firms’ assets. This effect appears to be more pronounced for small and less reputed firms. Information ambiguity further lowers firms’ market value and, in particular, the market value of innovative assets. We further show that high quality patents mitigate the negative effect of information ambiguity to some extent.  相似文献

A long stream of research has documented the positive effects that patents bring about to emerging firms in high technology industries. The general consensus is that patents contribute to firm growth because they confer monopolistic market rights, offer protection from competitors, increase the negotiating position of patent holders and other benefits. What has received relatively less attention in the literature is whether patents act as a signal that attracts investors such as venture capital firms. The handful of studies that have addressed that question has not analyzed whether the signaling function of patents decreases after the initial attraction of venture capital, as information asymmetries between investors and target firms reduce. In this study we hypothesize that patent activity has a signaling value that diminishes once information asymmetries between investors and funded firms lessen. To study our proposition we draw upon a longitudinal dataset of more than 580 U.S.-based biotechnology firms to empirically demonstrate that biotechnology firms that have submitted patent applications substantially increase the level of funding they receive for their first round of financing. In line with a reduction of information asymmetries once the initial investment has materialized, patent applications and granted patents have no effect on the growth of venture capital funds raised during the second round of financing. We conclude the study with a discussion of avenues for new research, implications for policy makers that consider the usefulness of the current patent system and with insights that can be employed by managers of firms in knowledge intensive areas such as biotechnology.  相似文献

In this investigation we use a modified Networked Readiness Index (NRI) framework to investigate whether (1) ICT capabilities impact public value creation, and (2) if the public value is associated with the socio-economic impact of ICT capabilities. In the case of this study the construct Public Value is represented via two different proxies. In the first case we use a perception-based measure of public value (as represented by the World Government Indicators) and in the second case we use a surrogate objective measure (as represented by the Cost of Business Startup Procedures (CBSP)). We use a six-step multi-method methodology that involves Cluster Analysis, Correlation Analysis, Decision Trees Induction, Data Envelopment Analysis, Association Rules Mining, and Ordinary Least Squares regression to conduct the inquiry in the context of 26 Sub-Saharan (SSA) economies. Results of our data analysis include: 1) the set of economies with better developed ICT Capabilities are relatively more efficient in converting ICT Capabilities into Public Value than the relatively poorer economies with less developed ICT Capabilities; 2) High levels of ICT capabilities in the areas of Affordability Readiness, Skills Readiness, the Political & Regulatory Environment, and Business Usage allow for relatively more efficient generation of Public Value.  相似文献

Previous studies provide evidence of learning from the mobility of scientists for the source and the hiring firms. However, we have a limited understanding of the competitive implications of such inter-firm mobility and associated learnings. Using a difference–in–difference approach on matched patents in the semiconductor industry in 1981–2010, we find that mobile scientists' patents receive more citations from rival firms after the mobility vis-à-vis before the mobility and vis-à-vis other similar patents. We conclude that rival firms respond to mobilities across other firms by attributing more attention to mobile scientists. Furthermore, the context of the mobility can determine the extent of response from rival firms. Rival firms are more likely to build on a mobile scientist's patents after mobility when the mobility occurs between technologically distant firms, the source firm or the hiring firm has low research experience, or the mobile scientist has considerable experience.  相似文献

Technological innovations often involve collaboration among firms from diverse industries. Existing literature has largely viewed participant diversity as a conduit for non-redundant information or complementary resources, thereby affecting the ex-post outcomes of innovation projects. However, it is seldom examined how projects are initially evaluated during the resource competition stage. In this study, we develop a theory of diversity as a cognitive primer, asking how collaborators from diverse backgrounds may affect external reviewers’ ex-ante evaluation of potential merits of an innovation project. We argue that there are two logics at work in the process of evaluating innovations: the logic of technological advancement and the logic of market value. When an innovation project involves firms from diverse industries, it may be perceived as having a fuzzier market identity, hence making it less appealing to reviewers who hold with the strong market value logic. However, the penalty associated with participant diversity should be less pronounced among reviewers who hold the technological advancement logic. We also expect the relationship between participant diversity and reviewers’ ratings to be moderated by project novelty and fuzziness of technology category. We find support for our hypotheses with a sample of collaborative innovation projects funded by the Advanced Technology Program of the U.S. National Institute of Standards and Technology.  相似文献

We draw on information risk theory and paradox theory to examine the additive and combined effects of disclosing exploration and exploitation information on cost of equity capital. We build on theory that presupposes that the information disclosed by a firm about its innovation activities will reduce information risk of investors. However, we contend that disclosure of exploration and exploitation innovation activities could convey potentially paradoxical expectations about a firm's future value. Based on longitudinal data of the UK FTSE 350 firms from 2011–2016, we show that firms tend to disclose more information related to exploration than exploitation. However, the bulk of market benefits are driven by exploitation rather than exploration disclosures—except for R&D-active firms that are rewarded for exploration disclosure. We also find that the combined disclosure is negatively associated with cost of equity capital, with the sub-population of R&D-active firms particularly accruing synergies from combined disclosure of both exploration and exploitation. These findings suggest that the market differentiates between exploration and exploitation information in addressing information risk, more so than previously assumed. We discuss implications for information-type-dependency in information-risk theory, the outward projection of internal paradoxes, capital market valuations of disclosure by R&D-active firms, opportunity-seeking by large publicly listed corporations, and policy implications.  相似文献

This empirical study examines small firms’ strategies for capturing returns to investments in innovation. We find that small firms’ strategies are qualitatively different from those found in earlier studies of both small and large firms. Most of the small firms examined here find informal means of protection, such as speed to market or secrecy, more important than patenting. Only firms with university cooperation—typically R&D intensive and science-based small firms—were likely to identify patents as the most important method of appropriating innovation returns in their field. Thus, the strategic choice for most small firms is between secrecy and speed to market. Firms that cooperate in innovation with horizontal partners or significantly depend on vertical partners tend to prefer speed, whereas process innovators with modest R&D investments or few cooperative R&D activities display a preference for trade secrets. Indeed, cooperation activities greatly influence the choice of intellectual property strategy for small firms. Earlier research has emphasized patents and trade secrets as key strategies of appropriation, yet these strategies do not appear to be very beneficial for small firms engaged in cooperative innovation. These results raise policy questions regarding the functionality of the existing system of intellectual property rights.  相似文献

Patents are an important signal of the unobserved quality of young, innovative firms. We study patents that protect radical inventions associated with high earnings potential but also a high risk of failure. These previously disregarded signals convey positive and negative information simultaneously, i.e., strong signals that have a dark side. We argue that whether firms that send such signals are attractive investment targets for venture capital (VC) investors depends on the characteristics of the investors. Reputable VC investors are attracted to the strong quality signals of patents protecting radical inventions and are better able than other VC investors to deal with the dark side of these signals through syndication. These effects are stronger in the first financing round than in follow-on rounds, as the (positive and negative) informational value of patents protecting radical inventions diminishes over time as information asymmetries between young firms and prospective VC investors are reduced. We test these predictions using a sample of 759 young life science firms and 555 VC investors. Econometric estimates from a matching model support our predictions.  相似文献

专利市场是经济活动中效率最为低下的市场之一。一方面,专利属于无形资产,很难评判其价值。另一方面,由于信息不对称,市场参与双方(发明人和使用者)均面临很大的搜寻和交易成本。然而较少有文献实证记录这些市场摩擦所带来的后果。本文记录中国个人专利申请的一个特别现象:与企业专利相比,个人专利被广泛认为质量较差;然而另一方面,个人专利在授权后的维持时间却长于企业专利。本文认为专利市场摩擦可以一定程度上解释该现象:由于搜索成本和信息不对称,相对于企业来说,个人发明人需要更长时间才能将其专利许可或转让给可以商业化的公司。个人发明人往往需要这些转让收益来收回发明的投资成本,为此他们会努力寻求潜在的授予方,而不得不维持专利到更长的时间。 本文提供一些实证证据来支持这个假说。在专利质量比较过程中,本文基于中国国家知识产权局的数据库,整理并建立了中国专利申请的详细数据并构建了若干质量指标。同时,作者利用谷歌专利数据库补充了专利权利要求项数量和专利引证这两个指标,为中国专利质量分析、知识传递与溢出提供了重要的数据来源。  相似文献

This paper analyses market valuations of UK companies using a new data set of their R&D and IP activities (1989-2002). In contrast to previous studies, the analysis is conducted at the sectoral-level, where the sectors are based on the technological classification originating from Pavitt [Pavitt, K., 1984. Sectoral patterns of technical change. Research Policy 13, 343-373]. The first main result is that the valuation of R&D varies substantially across these sectors. Another important result is that, on average, firms that receive only UK patents tend to have no significant market premium. In direct contrast, patenting through the European Patent Office does raise market value, as does the registration of trade marks in the UK for most sectors. To explore these variations the paper links competitive conditions with the market valuation of innovation. Using profit persistence as a measure of competitive pressure, we find that the sectors that are the most competitive have the lowest market valuation of R&D. Furthermore, within the most competitive sector (‘science based’ manufacturing), firms with larger market shares (an inverse indicator of competitive pressure) also have higher R&D valuations, as well as some positive return to UK patents. We conclude that this evidence supports Schumpeter by finding higher returns to innovation in less than fully competitive markets and contradicts Arrow [Arrow, K., 1962. Economic welfare and the allocation of resources for invention. In: Nelson, R. (Ed.), The Rate and Direction of Inventive Activity. Princeton University Press, Princeton], who argued that, with the existence of IP rights, competitive market structure provides higher incentives to innovate.  相似文献

This paper examines how the relationship between firm value and patent-based indicators of inventive activity has changed over time. We use data from more than 33,000 mergers and acquisitions deals between 1985 and 2007, and distinguish between American (USPTO) and European (EPO) patents. Our results indicate that over time EPO patents have become the dominant indicator of innovative activity, while USPTO patents have no effect on firm value near the end of the sample period. The results are robust to controlling for citations and are especially strong for small firms, for firms operating in the drug and chemical industries, and when target and acquiring firms operate in different industries or countries.  相似文献

The shakeout period after the emergence of a dominant design is very important to technology followers and niche market producers, who need adjust to significant changes in the competitive landscape. We posit that such innovating firms use strategic signals that address technical-, market-, and standards-uncertainty associated with their innovations to communicate with market participants to reduce participants' perceived uncertainties associated with the innovative products. Studying technology followers and niche market producers in the personal computer industry during its 1982–1989 shakeout period, we found that technology followers and niche market producers differ in their use of technical-, market-, and standards-related signals. Additionally, using event study methodology, we find that technology followers' strategic signals have significant positive impacts on both their own and other followers' stock prices. Meanwhile, niche market producers' strategic signals have significant positive impacts on their own stock prices, but not significant impacts on other niche market producers and technology followers' stock prices.  相似文献

By using a sample of 793 inventors drawn from the PatVal-EU dataset, this paper explores three aspects of patent production at the individual inventor level: (1) the number of EPO patents that the inventors produce; (2) the average value of their inventions; (3) the production of the most valuable patents. By jointly estimating the three equations we find that the inventors’ level of education, employment in a large firm, and involvement in large-scale research projects positively correlate with quantity. Yet, apart from the size of the research project, none of these factors directly influence the expected value of the inventions. They do, however, have an indirect influence, as we find that the number of patents explains the probability of producing a technological hit (the maximum value). Also, there is no regression to the mean in the invention process at an individual level, as the number of inventions that an inventor produces is not correlated with the average value.  相似文献

We examine patent licensing business models of non-practicing entities that generate revenue by selling, licensing, or litigating patents. They may also pursue R&D activities, invent new technologies, or provide services to inventors or product companies. We describe their business models and patent market behavior and then compare their litigation strategies against product companies using a matched sample of highly comparable patents. The main differences among patent licensing firms stem from their technological capabilities, patent portfolio sizes, and external relationships. We find that licensing firms with technological capabilities often pursue litigation until decision and engage in forum shopping. In contrast, litigation incidence, parties involved, and outcomes are primarily determined by patent characteristics, not entity types. Licensing business models drive the acquisition of certain types of patents that influence the outcomes of the patent system. We argue that patent policy should strengthen mechanisms to discover invention quality rather than focus on the amount of litigation or types of entities.  相似文献

We examine how the ways in which firms geographically configure their global portfolios of R&D units influence the effectiveness of firms’ own R&D investments and of external technical knowledge in enhancing firm performance. Our analysis indicates that the strength of these effects depends on the extent to which firms spread their R&D units across countries (geographic dispersion of R&D) and the extent to which firms establish multiple R&D units within each country (co-location of R&D). We show that geographic dispersion and co-location are associated with distinct value creation and value capture mechanisms and in turn lead to different performance outcomes. Although geographic dispersion enhances the effects of a firm’s own R&D on its performance, R&D co-location limits such effects. These relationships are reversed when we consider the effects of external technical knowledge on firm performance. R&D co-location, rather than geographic dispersion, is what renders the exploitation of external knowledge more effective in enhancing firm performance. Our results suggest that future research should shift its focus from the degree of R&D globalization to how a portfolio is globalized and geographically structured.  相似文献
