Does the adaptation of incumbent firms to new methods of inventing follow similar patterns across industries and inventions? We investigate this question in the context of the revolutionary scientific advances enabling biotechnology and nanotechnology, both of which represent inventions of methods of inventing for incumbent firms. We hypothesize that an incumbent firm's ability to exploit these new methods of invention depends initially on access to tacit knowledge on how to employ the new methods. Over time, however, as firms learn and/or the knowledge becomes codified in routine procedures or commercially available equipment, inventive output is more highly dependent on traditional R&D investments. We empirically test these hypotheses on two longitudinal samples over the 21-year time period between 1980 and 2000: 80 incumbent pharmaceutical firms generating 15,607 biotechnology patents, and 249 firms across a diverse set of industries that were granted a total of 3236 nanotechnology patents. We find broad support for our conjectures. 相似文献

Stars hold a large portion of organizational knowledge, and their sudden absence may have non-trivial consequences for firms. In this study, I investigate what happens to the knowledge of star inventors following their absence. In particular, I consider the composition of stars' ties with coinventors and examine how it affects the future use of stars' knowledge (i.e., patents). Using the death of star inventors as an exogenous cause for their absence in firms, I find that the use of a star's patents in a firm's subsequent inventive efforts declines following the star's death. The results also indicate that when star inventors frequently collaborate with coinventors, the negative effect of stars' absence on the future use of their knowledge is somewhat alleviated. Further, the presence of central inventors in stars' collaboration networks increases the relative use of stars' knowledge in future inventions. The findings inform managers about conditions that favor “passing the torch” of knowledge from stars to their peers. 相似文献

Today's Edisons or weekend hobbyists: technical merit and success of inventions by independent inventors 总被引：1，自引：0，他引：1
We set out to determine if independent inventors can be considered “heroes” or “hobbyists”, that is, if they produce the most or the least influential inventions in a product category. We study patented inventions by independent and firm-based inventors by comparing patents along four dimensions: Patent citation impact, detail, scope, and maintenance. Examining 225 tennis racket patents granted in the US between 1981 and 1991, we find that independent inventors are a heterogeneous group who generate inventions that are overrepresented both among the most impactful and the least impactful patents. The metrics we develop provide insight into ex ante identification of the importance of inventions. 相似文献

We investigate the impact of deadly terrorist attacks on inventor productivity and mobility in the U.S. During the five-year window after such events, nearby firms generate fewer and less impactful inventions. Moreover, their inventors typically exhibit a post-attack decline in their patent production, unless they move to a distant company (which some tend to do after an attack). Firms' financial constraints and inventor talent appear to provide channels underlying our productivity and mobility findings, respectively. These results provide novel insights about the impact of shocks that distort the invention process and promote the mobility and reallocation of inventors among firms. 相似文献

Despite a substantial body of research investigating the market significance of inventions by independent inventors, relatively little attention has been devoted to understanding their technological significance. A recent study conducted by [Dahlin, K., Taylor, M., Fichman, M., 2004. Today's Edisons or weekend hobbyists: technical impact and success of inventions by independent inventors. Res. Policy 33, 1167-1183] on the tennis racket industry shows that independent inventors are a heterogeneous group which includes both “heroes” who contribute substantially to technological progress and “hobbyists” who make only a marginal contribution. What is not asked - and therefore not explained - is why this distinction arises. In this paper, we focus on the type of prior technological knowledge (in terms of technological specialization and diversity) applied by independent inventors and their corporate counterparts as a factor explaining differences in technological impact. Our empirical setting is the field of medical equipment technology. We find that independent inventors are more sensitive to the negative effects of technological diversity than their corporate counterparts. Furthermore, our study reveals that technological specialization pays off more for independent inventors than for their corporate counterparts. Therefore, those independent inventors who apply low degrees of diversity and high degrees of specialization are capable of reaching the same level as or even outperforming their corporate counterparts, thus becoming “heroes”. Based on our findings, we discuss implications for research and corporate practice. 相似文献

We analyze how mid-range universities can contribute to industrial change through the transfer of tacit and codified knowledge in the areas of spin-offs; licensing and patents; contract research, consultancy and reach-out; and graduate and researcher mobility. We use archival, survey and interview data relating to mid-range universities in mid-range environments in the UK, Belgium, Germany and Sweden. Our findings suggest that mid-range universities primarily need to focus on generating world-class research and critical mass in areas of expertise, as well as developing different types of intermediaries. Mid-range universities may need to develop a portfolio of university-industry linkages in terms of the scope of activities and the types of firms with which they interact. We also show that different intermediaries have important roles to play in developing university-industry linkages for mid-range universities. 相似文献

US faculty patenting: Inside and outside the university 总被引：2，自引：0，他引：2
In a sample of 5811 patents with US faculty as inventors, 26% are assigned solely to firms rather than universities as dictated by US university employment policies and Bayh-Dole. We relate assignment to patent characteristics, university policy, and inventor field. Patents assigned to firms (whether established or start-ups with inventor as principal) are less basic than those assigned to universities suggesting firm assigned patents result from faculty consulting. Assignment to inventor-related start-ups is less likely the higher the share of revenue inventors receive from university-licensed patents. Firm assignment also varies by inventor field and whether the university is public or private. 相似文献

从知识的视角,一项职务成果就是一个由显性知识和隐性知识构成的知识包,分属于科研单位和发明人控制,因此,是否赋予发明人主导职务成果转化,既是一个重大的理论问题,也是一个重大的政策问题。论文首先提出研究假设,即由于显性知识与隐性知识的控制权分离,导致转化主体分别与研发主体、消费主体、融资主体分别出现技术距离、市场距离和融资距离;而且这三类距离越大,越需要发明人来主导职务成果转化;随后,采用案例研究方法,以甲醇制烯烃成果转化案例进行实证检验。论文的实证结论显示,采用创业分拆方式来推进发明人主导职务成果转化,即把发明人及其职务成果整体孵化转化为企业性质的转化主体,由发明人主导职务成果转化,消除了这三类距离,促进职务成果顺利转化。 相似文献

This paper compares corporate and academic patents and tests whether they have similar value distributions and share common determinants of value. The empirical results based on an in-depth analysis of 400 biotech patents applied for by Belgian universities and firms lead to the following observations: (i) academic and corporate patent value distributions have similar levels of ‘skewness’; (ii) the identification of the institutional origin of knowledge allows for an improved understanding of the value determinants and (iii) there is a need to stimulate star scientists to codify their tacit knowledge into valuable patents. 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

知识元素网络搜索与突破性技术发明形成 《科学学研究》2021,39(5):794-804
突破性技术发明在企业参与全球技术和市场竞争中的作用已经得到广泛认可,但如何通过知识搜索和重组形成突破性技术发明仍是学术界和企业界关注的热点问题。本文基于知识搜索重组视角和社会网络理论,考察知识元素网络搜索与突破性技术发明形成的关系,并基于团队学习理论揭示发明人团队特征的调节作用。然后,利用美国专利商标局（USPTO）1995-2010年纳米技术领域6132条授权发明专利进行实证检验,结果发现：（1）知识元素的网络中心度越低,占据结构洞位置越少,突破性技术发明形成的概率越高。（2）与合作发明人相比,单独发明人搜索网络中心度较低和结构洞较少的知识元素创造产生突破性技术发明的概率更高。（3）发明人团队技术经验越丰富,搜索网络中心度较低和结构洞较少的知识元素创造产生突破性技术发明的概率越高。本研究从知识元素网络和发明人团队视角系统揭示了突破性技术发明的形成机制,对企业面向突破性技术发明的发明人团队构建及知识组合战略实施具有重要启示。 相似文献

The technological origins of radical inventions 总被引：3，自引：0，他引：3
This paper aims to trace down the origins of radical inventions. In spite of many theoretical discussions on the effect of radical inventions, the specific nature of radical inventions has received much less attention in the theoretical and empirical literature. We try to fill that void by an empirical investigation into the specific origins of radical inventions. We explore this issue by a close examination of 157 individual patents, which are selected from a pool of more than 300,000 patents. In contrast to the conventional wisdom that radical inventions are based less on existing knowledge, we find that they are to a higher degree based on existing knowledge than non-radical inventions. A further result that follows from our analysis is that radical inventions are induced by the recombination over more knowledge domains. The combination of knowledge from domains that might usually not be connected seems to deliver more radical inventions. 相似文献

Economic theory views patents as policy instruments aimed at fostering innovation and diffusion. Three major implications are drawn regarding current policy debates. First, patents may not be the most effective means of protection for inventors to recover R&D investments when imitation is costly and first mover advantages are important. Second, patentability requirements, such as novelty or non-obviousness, should be sufficiently stringent to avoid the grant of patents for inventions with low social value that increase the social cost of the patent system. Third, the trade-off between the patent policy instruments of length and breadth could be used to provide sufficient incentives to develop inventions with high social value. Beyond these three implications, economic theory also pleads for a mechanism design approach: an optimal patent system could be based on a menu of different degrees of patent protection where stronger protection would involve higher fees, allowing self-selection by inventors. 相似文献

We study the role of the relationship among inventors and intermediaries in the licensing of university inventions. We suggest that a prior inventor-intermediaries relationship positively influences licensing rates through selective retention of higher quality relationships and mutual learning in the relationship, enabling intermediaries to reduce both information asymmetry and search costs between inventors and potential licensees. We argue that the influence of a prior inventor-intermediaries relationship on licensing is especially important before intellectual property protection is attained and can be substituted by the buyer-side contacts of inventors and intermediaries. We test these predictions using 919 inventions from the technology transfer office at Stanford University. This study has implications for the policies and design of university technology licensing organizations. 相似文献

In this paper, we explore the impact of a firm's workers’ replacements on innovation performance by using rich matched employer–employee panel data for the Veneto region of Italy. We take the well-known resource-based theory of the firm as our departure point, and develop a set of hypotheses which we test empirically with negative binomial regressions. We find that workers’ replacements significantly dampen innovation performance, coherently with the idea that they generate losses in the tacit knowledge base of the firm. We also find that workers’ replacements are especially detrimental to large and young firms, possibly because large companies benefit comparatively less from ‘diaspora’ effects and because innovative capabilities in young firms are mostly dependent on specific human capital. Finally, our results show that firms’ location in industrial districts significantly mitigates the negative impact of workers’ replacements, and that a similar picture emerges when firms are more exposed to knowledge spillovers, particularly of related knowledge. 相似文献

Mapping technologies into industries is frequently required in empirical innovation studies, but many concordances only provide coarse mappings. We develop a novel concordance between industries and technologies making use of linked inventor-employee data for a large sample of German patents filed at the European Patent Office between 1999 and 2011. Inventors listed on these patents are matched and disambiguated with German social security records. Employment data recorded in this database include detailed industry codes describing the industrial activities of the inventors’ establishments. These linked microdata allow us to identify the precise industrial origin of inventions, combine them with technology classifications from the inventors’ patents and to generate novel concordance tables. We evaluate our approach by comparing the concordances with existing work. Moreover, in an empirical application, we find that patent based indicators represent valid proxies for the innovation performance of industries and thus help to measure innovation in the absence of other survey based indicators. Service sector innovation activities, however, appear to be barely represented by the patenting activities of inventors and establishments. 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
