This study examines how inventors’ breadth and depth of expertise influence innovation in 3M, a company renowned for sustained innovation for over a century. While prior research tends to examine a single indicator – the technical success achieved by the inventor – our study differentiates between three indicators of a successful inventor: (1) the number of inventions generated; (2) the extent to which the inventor has a significant impact in his or her technical domain; and (3) the inventor's career success, in terms of the commercial value they have brought by converting their inventions into products that generate sales for commercial organizations. We found that breadth of inventor expertise relates to the generation of many inventions, but not necessarily to those that are technically influential. Depth of inventor expertise enables individuals to generate technically influential inventions, as measured by patents granted. However, both breadth and depth of expertise are required for innovators to be deemed highly valuable, based on their records of effectively converting inventions into commercially successful products. Our study extends prior research on innovation in two ways. We provide a comprehensive view of how inventors’ expertise influences innovation and also show how inventors with different expertise profiles can contribute in unique ways to their organization. 相似文献

The mobility of inventors leaves behind their patented inventions at sourcing firms, yet there is little scholarly insight into how firms handle those intellectual properties. We investigate this important issue by developing a framework of tacit-codified knowledge interdependence. We theorize that tacit and codified knowledge offer the intellectual and legal pillars of corporate inventions, which complement each other in value creation. Inventor mobility decouples the two pillars and reduces the maintenance likelihood of the left-behind patents. The negative impact is greater for inventions that are complex or rely less on internal prior art because the tacit knowledge loss is more destructive and unrecoverable. However, when inventors move to competing or litigious target firms, the relationship between mobility and patent maintenance becomes less negative or even turns positive because the left-behind patents can be leveraged to hedge against the risk of knowledge leakage. Applying a two-stage Coarsened Exact Matching approach to construct a sample of 36,204 U.S. patents with comparable leaving and staying inventors from public firms between 1983 and 2010, we find strong evidence supporting our framework. Our findings highlight the intricate interdependence of tacit and codified knowledge in corporate inventions and add to the literatures on inventor mobility and intellectual property management. 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

There is a considerable volume of prior research on the relationship between innovation and patents. Those research studies reveal that patents contain a great deal of noise, and unless a correction is made in terms of the value of individual patents, a simple count of the number of patents does not constitute a very useful indicator. From research that has been conducted for the purpose of finding such an indicator to show the value of individual patents (that is, research to identify the characteristics of valuable patents), many kinds of value indicators have been proposed. Nevertheless, research hitherto has focused primarily on business or private value derived from the possession of patents, and little attention has been paid to value in terms of technical knowledge or social value. In a survey of inventors conducted by RIETI in 2007, terminology describing broad concepts was used when questioning inventors about the value of individual patents, and this has provided an excellent opportunity to analyze the multiple factors lying behind the value of patents and how they impact one another.The purpose of this research is to use data from the RIETI survey of inventors and structural equation modeling methods to elucidate the relationships between the technological and business value of patents, and the latent factors that influence them. The findings show that a scientific-technological motive for inventors would have a positive effect on both the business and technological value, meanwhile, the monetary or promotion motive would not have any direct effects on the value of a patent. The model also suggests that academic linkage would have a strong positive effect on the technological value but a weak negative effect on the business value. Furthermore, these relationships differ more markedly according to technological field. 相似文献

This paper studies the relationship between migration and the productivity of high-skilled workers, as captured by inventors of international patent applications. Using machine learning techniques to uniquely identify inventors across patents, we are able to track the migration patterns of nearly one million individual inventors across countries. Migrant inventors account for more than nine percent of inventors in our sample. The econometric analysis seeks to explain the recurring finding in the literature that migrant inventors are more productive than non-migrant inventors. We find evidence that migrant inventors become about twenty-three percent more productive after having migrated. The disambiguated inventor data are openly available. 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 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

高校专利运营是一个包括发明创造、价值增值和价值实现三个主要环节的复杂动态过程。以美国高校为样本,基于动态系统视角分析发明人专利收益分配比例对高校专利运营不同环节的影响,并针对发明人专利收入与科研经费支出对高校专利运营的影响差异进行比较分析。研究发现：近70%的样本高校中发明人专利收入与发明披露量之间不存在显著的相关性;而在发明人专利收入与发明披露量显著相关的高校中,发明人专利收益比例对高校专利运营的发明创造环节作用明显,对价值增值环节作用因样本而异,但对价值实现环节的影响微乎其微;同时,当专利收益分配基数与科研经费支出之间相差悬殊时,与通过提高发明人收益比例增加发明人专利收入相比,同比增加科研经费支出对专利运营各环节的影响更大。一刀切式地提高发明人收益比例对高校专利运营的促进作用十分有限。据此提出,高校应细化发明人收益分配方案,并综合运用多种激励方式,发挥政策协同作用。 相似文献

Cheaper patents 总被引：1，自引：0，他引：1

The 1883 Patents Act in Britain provides perspective for modern patent policy reforms because it radically changed incentives for inventors by reducing filing fees by 84 percent. Patents increased 2.5-fold after the reform, which was evenly distributed across the geography of inventors, the organization of invention and sectors. By realizing a large demand for cheaper patents the reform increased the propensity to patent and shifted inventive activity inside the patent system. It did not increase innovation as measured by changes in the distribution of high and low value patents and citations to English inventor patents in the United States. 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

职务发明人合理分享创新收益是实现职务发明创造转化和实施运用的有效激励手段。《专利法（修正案草案）》对此予以了明确。作为职务发明人智力成果的价值体现和促进职务发明人推动发明创造成果转化的制度激励，职务发明人合理分享创新收益具有正当性。但是，有限的“约定优先”、“合理性”标准的模糊对待、国有资产法律法规的限制性规定、职务发明相关权利的杂糅处理和单位知识产权运营能力的不足对职务发明人实现创新收益分享形成掣肘。实现职务发明人合理分享创新收益，首先应明确“合理性”的判断标准，即在程序正义的基础上根据职务发明人的创造性贡献程度和职务发明所产生的经济效益确认收益分享的合理限度。其次，职务发明创造的专利权作为一项“权利束”，应将其分而处之，明晰各参与主体间的权利边界。再次，应优化国有资产属性的职务发明创造的管理体制，探索建立以科技法律制度为核心，兼容其他各部门法律法规的无形资产管理制度。复次，在产权明晰的基础上，应鼓励单位与职务发明人之间通过约定分享收益。最后，实现单位与职务发明人的互利共赢还需要提升单位的知识产权运营能力，以实现职务发明成果的转化利用。 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

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

随着我国发明专利申请数量的迅猛增加,如何通过事前和事后指标测度并识别技术和经济价值高的突破性技术发明就成为学术界面临的焦点问题。针对我国专利普遍缺乏引文信息的现状,本文利用专利的国际专利分类（IPC）信息构建两两专利相似度指标,并引入时间维度对过去、当前以及未来三个时间段的专利相似度比较,测度专利的新颖性、独特性和影响力,从而构建突破性技术发明的综合识别方案。然后,以纳米技术为例,利用美国专利商标局（USPTO）在1975-2015年的授权发明专利数据进行实证检验。结果表明：（1）基于专利IPC四位和六位分类的相似度指标分别可以识别出6.23%和5.06%的纳米技术专利为突破性技术发明;（2）基于专利相似度识别的突破性技术发明与基于专利被引数识别的突破性技术发明具有显著的正相关关系,但是,两类识别方法得到的结果中仅有不足总样本的0.5%是相同的,表明以往单纯依赖专利被引数据识别突破性技术发明可能存在一定偏差;（3）对突破性技术发明来源特征的实证检验表明,基于专利相似度和基于专利被引数的突破性技术发明的发明人和组织来源特征基本一致,而发明层面的知识来源特征呈现不一致的结果,进一步反映出两类识别方案的差异性。本文基于专利相似度构建的突破性技术发明识别方案既为企业在实践中挖掘和利用高价值的发明专利提供参考,也对未来突破性技术发明相关研究达成一致结论具有重要意义。 相似文献

How does patent scope influence licensing propensity of inventions? Prior studies have often been confined to specific industries or settings, and their results have been mixed with studies showing a positive, a negative, or even no significant relationship. Also, while some have explored moderating factors that might influence the patent scope-licensing relationship, a systematic investigation of the heterogeneous effects of patent scope on licensing at the invention level has not been undertaken. This study combines a broad sample of publicly reported patent licensing agreements and a novel methodology that captures an exogenous variation in patent scope to re-investigate the relationship between patent scope and licensing and to explore key invention and inventor characteristics that could influence this relationship. The results show that narrowed patent scope leads to a substantial decline in licensing propensity of inventions and that the effect is stronger for high-quality, science-based, and novel inventions as well as for inventions generated by small inventors. 相似文献

Academics and policy makers are investigating the relations between science and technology in the emerging field of nano science and technology (NST) and the effectiveness of different institutional regimes. We use multiple indicators to analyze the performance of inventors working in NST. We clustered patents into three groups according to the scientific curricula of the inventors. The first group consists of patents whose inventors are all authors of at least one scientific publication in NST, while the second is made up of patents invented by individuals who have no scientific publication in the field. Thirdly, we isolated those patents that have at least one inventor who is also author of at least one scientific publication in NST. The underlining presumption of this classification is that of a proxy of different institutional complementarities of inventive collective action in NST. 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

Despite the economic significance of patented university research, it is difficult to measure the economic value of academic patented inventions and observe the extent to which universities are able to capture such value through patent licensing. Moving beyond assessing commercialization performance by simple statistics, we propose a new approach to benchmarking university patents and commercialization performance based on comparative corporate patent value. Our procedure involves matching university patents to patents with similar patent characteristics granted to public corporations, then estimating the “potential value” of these university patents by stock market reactions to grants of the matched corporate patents. These estimated values of university patents can significantly explain the technology-level income from licensing by a leading US research university and the annual licensing income of the member universities of the Association of University Technology Managers’ (AUTM). We find that AUTM universities realize an average of 16% of the estimated value of matched corporate patents. We also investigate correlates of university‐level potential patent value and suggest avenues for future research. 相似文献
