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

This article provides a review of the private and social functions of patents using data and evidence from the economic and management literature. While patents provide incentives to invent by providing private protection to appropriate the returns on inventions, they also have broader effects. For example, in this paper we focus on the fact that they provide signals about the value of new firms, disclose information about the invention, and encourage the exchange of inventions and ideas in markets for technology. In order to better understand the relative importance of the implications of patents, patent agencies and stakeholders should invest to a greater extent in data collections or in creating the conditions for research designs and experiments that nail down causal effects and mechanisms. Available data are not created with these identification strategies in mind, which limits the questions that scholars can ask. Systematic studies that identify different effects of patents can provide the basis for rigorous evidence-based management and policy about patents. This would imply a wider shift from a world in which managerial and policy analysis is distinct from practice, to a world in which analysis and implementation are increasingly co-produced, and there is greater integration between them. 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

The study examines the role of a patent filed by government scientists in regard to the dissemination of scientific discoveries in government laboratories. While a patent filed by government scientists decreases the rate of follow-on patents in a technological area that overlaps with the areas of the focal patent, it increases the rate of follow-on patents in non-overlapping technological areas. The increase in follow-on inventions is attributed to risk-taking inventions, that is, inventions involve a high chance of resulting in either impactful or failure patents, rather than incremental inventions. It is also characterized by inventions with a high level of originality. Inventors in distant locations in terms of geographical and technological proximity are most affected by the patents filed by government scientists. The patent effect is pronounced when the government scientists involved in the focal discovery have fewer social connections and when the scientific field is less familiar in the industry. These findings are consistent with the idea that patenting by government scientists helps facilitate the dissemination of technological information or potential of scientific discoveries in government laboratories. Policy and managerial implications are also discussed. 相似文献

How do knowledge-intensive business services (KIBS) protect their inventions from imitation by rival firms when choosing among various protection mechanisms? Data from the 2003 Statistics Canada Innovation Survey on services are used to investigate this issue by looking into complementarities, substitution and independence among eight protection mechanisms. A Multivariate Probit (MVP) model is estimated to take into account the fact that KIBS simultaneously consider many alternative intellectual property (IP) protection methods when they attempt to protect their innovations. Results show that patents, registration of design patterns, trademarks, secrecy and lead-time advantages over competitors constitute legal and informal methods that are used jointly. These complementarities suggest that IP protection mechanisms that are interdependent and reinforce each other to protect innovations from imitation by rival firms constitute a pattern on which firms rely to protect their innovations from imitation. A second pattern is based on the fact that KIBS rely on patents and complexity of designs as substitutes, and tend to use registration of design patterns and complexity of designs as substitutes in protecting their innovations from imitation. A third emerging pattern concerns protection mechanisms that are independent from each other and exhibit no synergy, and do not reinforce each other to protect innovations from imitation by other firms. 相似文献

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. As a result, firms risk their patent applications to be pre-empted or to be infringed upon by rivals. While both aspects constitute major challenges for the appropriation of returns to inventive activity, extant literature suggests that participation in the market for technology might actually resolve or at least alleviate these problems. In this paper, we investigate the effect of pre-empted and infringed patents on firms’ engagement in in- and cross-licensing. Based on a sample of more than 1100 German manufacturing firms our results show that firms engage in in-licensing as a reaction to pre-empted patents and in cross-licensing if their protected IP was infringed upon. However, these effects vary depending on the fragmentation of technology fields and whether the firm operates in a discrete or complex product industry. 相似文献

Appropriate intellectual property protection and economic growth in countries at different levels of development 总被引：1，自引：0，他引：1
This paper examines how the role of patents and utility models in innovation and economic growth varies by level of economic development. Using a panel dataset of over 70 countries, we find that patent protection is an important determinant of innovation and that patentable innovations contribute to economic growth in developed countries, but not in developing. Instead, in developing economies, a minor form of intellectual property rights (IPRs) - namely utility models - is conducive to innovation and growth, controlling for other factors. Using Korean firm level data as a case study, we find that utility model innovations contribute to firm performance when firms are technologically lagging and that those minor innovations can be a learning device and thus a stepping stone for developing more patentable inventions later on. Upon reaching higher levels of technological capabilities, firms become more reliant upon patents and less on utility models. Thus the lesson here is that patent protection enhances innovation and economic growth in countries where the capacity to conduct innovative research exists. Where this capacity is weaker, a system that provides incentives to conduct minor, incremental inventions is more conducive to growth. The significance of this paper is to emphasize the importance not just of the strength of IPRs but of the appropriate type of IPRs for economic development. 相似文献

National surveys of R&D labs across the manufacturing sectors in the US and Japan show that intraindustry R&D knowledge flows and spillovers are greater in Japan than in the US and the appropriability of rents due to innovation less. Patents in particular are observed to play a more central role in diffusing information across rivals in Japan, and appear to be a key reason for greater intraindustry R&D spillovers there, suggesting that patent policy can importantly affect information flows. Uses of patents differ between the two nations, with strategic uses of patents, particularly for negotiations, being more common in Japan. 相似文献

This paper examines the role of various inter-organizational relationships in patent development, and how these relationships contribute to patent competitiveness. It takes the perspective of individual inventors and describes how they utilize external knowledge in the development of patents. Based on a case study of a European telecom operator, we found interaction with R&D consortia, suppliers and customers to support inventors in the development of new ideas for patents and in solving related problems. In terms of patent competitiveness, buyer-seller relationships were more valuable for an operator than R&D consortia relationships, as they reduced the market and technology uncertainty related to the patent. 相似文献

Motives to patent: Empirical evidence from Germany 总被引：4，自引：0，他引：4
Against the background of the patent upsurge, we first analyse the role of patenting and alternative instruments to protect intellectual property, based on a sample of German companies active in patenting. In a second step, we investigate the motives to patent, considering sector and company size effects. We find that company size matters, both for the importance of instruments and the motives to patent. Especially important are the new strategic motives to patent, like using patents to improve a company's own position in negotiations with partners, licensees and the financial sector, or to use patents as incentives for R&D personnel or performance indicators—these correlate positively with company size. We derive some possible challenges for future patent policies from these insights. 相似文献

Using a unique database on Swedish patents owned by small firms and individuals, survival models estimate how different factors influence the decision to commercialize the patents. Such an analysis has seemingly never previously been undertaken. Since the owners know more about the patents than potential external financiers, problems related to asymmetrical information are present. To overcome these problems when inventors and small technology-based firms need financing, Sweden has for a long time relied on government support rather than private venture capital firms. The empirical results show that the larger is the share of patent-owners’ costs covered by government financial support during the R&D phase, the lower is the probability of patents being commercialized. This lower degree of commercialization is likely to depend on (1) the soft terms of the government loans, where the patent owner can avoid paying back the loan if the patent is never commercialized and/or (2) that the government is not able to select promising projects. The first explanation is related to moral hazard and the second one to adverse selection. The policy suggestion is for government to change the design of the loans, to base them on firms rather than projects. 相似文献

The value of U.S. patents by owner and patent characteristics 总被引：1，自引：0，他引：1
James Bessen 《Research Policy》2008,37(5):932-945
This paper uses renewal data to estimate the value of U.S. patents, controlling for patent and owner characteristics. Estimates of U.S. patent value are substantially larger than estimates for European patents, however, the ratio of U.S. patent value to R&D for firms is only about 3%. Contrary to a common assertion, patents issued to small patentees are much less valuable than those issued to large corporations. Litigated patents are more valuable, as are highly cited patents. However, patent citations explain little variance in value, suggesting limits to their use as a measure of patent quality. 相似文献

Cheaper patents 总被引：1，自引：0，他引：1
Tom Nicholas 《Research Policy》2011,40(2):325-339
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

The relationships among R&D and other innovation activities, patents granted and sales of product innovations influenced by various specified characteristics of a NIS are investigated at the national level and tested on data for 14 EU nations in 1992 and 1996. The statistical results show patents to depend on sales of product innovations. Furthermore, both national innovation outcome indicators depend on largely the same macro- and micro-economic conditions while they differ in additional explanatory conditions, namely governmentally regulated institutional conditions for patents and firm specific characteristics for sales of product innovations. 相似文献

随着中国知识产权保护水平的提升,我国专利诉讼进入快速增长阶段,大量出现借助同一专利反复发起诉讼的情况。基于2000-2014年我国专利民事侵权诉讼数据,本文识别出发生过多次诉讼的专利,并进一步对其基本特征及诉讼结果进行了考察。研究表明：第一,与美国进入庭审阶段的多次诉讼发起人多为败诉不同,我国多次诉讼专利原告在进入庭审阶段后通常胜诉,尽管停止侵权诉求（取得市场禁令）更容易获得法院支持,但损害赔偿金额却未与多次诉讼产生显著的正相关性（表现为负相关）。第二,我国专利诉讼案件中大量使用了外观设计和实用新型专利,但在控制年度、产业、地区等变量后,发明专利被用于多次诉讼的倾向显著更高,这与总体诉讼样本中涉及发明的比重不高形成了鲜明反差。第三,多次诉讼专利具有地区和行业集中特征,东部出现多次诉讼专利的概率较小,制药、化学和生物技术领域产生多次诉讼专利的概率显著低于传统制造与机械行业。本文的实践应用价值和政策指向在于,通过对多次诉讼专利的分析为解决我国本土重复侵权、策略性商业维权以及可能的专利滥诉和司法逆向选择问题提供经验证据。 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

This paper presents data from Brazilian Patent Office (Instituto Nacional de Propriedade Industrial, INPI) and compares them with data from the United States Patent Office (USPTO). Developing countries have technological activities that are important locally but not significant at international level (imitation, local learning, adaptation of foreign innovations). These activities might be patentable only at national level. Therefore, the study of domestic patents of developing countries provides a broader picture than USPTO patents. This paper compares 8309 INPI patents with 475 USPTO patents (between 1980 and 1995). Domestic patent data show peculiarities in the Brazilian case, possibly shared with other countries in similar technological level: (a) high share of individual patents; (b) foreign-owned firms with important activities; (c) low firm involvement in R&D activities. Some characteristics are shared with developed countries: (a) domestic firms as the major patentees; (b) according to firm size, there is a U-shaped distribution of patents; (c) evidences of multi-technology large firms; (d) a relatively small share of firms have more than one patent in the whole period. The contrast between USPTO and national patenting statistics shows different rankings according to ownership structure, leading firms, industrial sectors, and international patent classification. These differences highlight sources of international competitiveness and point to weaknesses in Brazilian innovative activities. This paper concludes evaluating the contributions (and weaknesses) of this database for the evaluation of the Brazilian National System of Innovation. 相似文献
