On the relationship between environmental management, environmental innovation and patenting: Evidence from German manufacturing firms 总被引：1，自引：0，他引：1
This paper analyses empirically the relationship between environmental innovations, environmental management and patenting. In particular it tests a number of propositions on how environmental management systems and the interaction with environmentally more or less concerned stakeholders are associated with the probability of firms to pursue innovation in general (measured as patenting behaviour) and specifically environmental innovation (measured based on firm self-assessment and through patent data). In applying a negative binomial as well as binary discrete choice models the relationship is studied using data on German manufacturing firms. As a novel and important insight, the study finds that environmental innovation can be meaningfully identified using patent data and that environmental innovation defined this way is less ubiquitous than self-reported environmental innovation. It also reveals that the implementation level of environmental management systems has a positive effect exclusively on environmental process innovation, whereas it is negatively associated with the level of a firms’ general patenting activities. For environmental product innovation and patented environmental innovations a positive relationship with environmentally concerned and a negative link with environmentally neutral stakeholders is found. 相似文献

This paper studies the patterns of innovation in the ICT field using patents and patent citations. It provides an original methodology to identify ICT applications using patent abstracts and selecting the most frequent sequential triples of words without any a priori selection of keywords. This paper shows that the set of IPC classes related to ICT is broader than the one usually considered.Moreover, our results show that ICT applications can be distinguished into two main groups in terms of growth and structure of innovative activities, technological pervasiveness, and knowledge sources. High opportunity ICT applications are characterised by high growth of patenting activity, high rate of entry of new innovators and high concentration of technological activity across firms. They also display a diversified knowledge base in terms of technological domains and actors involved. Conversely, low opportunity ICT applications are characterised by a lower growth and by a lower concentration of innovative activities across firms, as well as by a lower rate of entry of new innovators. Innovations in these ICT applications show less diversified knowledge sources and a higher degree of internal knowledge base. 相似文献

A new comprehensive patent database based on patent applications filed with the Japanese Patent Office is described. We present the methodology for the construction of this database, the IIP Patent Database, its basic features and we discuss the recent history of patenting in Japan. We also compare citing-cited patterns of Japanese patents in this database with the citing-cited patterns for the same patents registered in the US, using OECD patent family information to identify US counterparts. We found similar patterns in the two countries, although citation is provided by patent examiners in Japan, while in the US a large share of citations is made by inventors. 相似文献

This paper compares and contrasts the invention patents of the US and China focusing on the application and granting practices. The findings show that both countries appear to make efforts to provide equal treatment to domestic and foreign applicants for patents in terms of pendency, but domestic applicants seem to enjoy more certainty of the patent being granted within the pendency period than foreign applicants in both countries. As regards grants, the US is equal in granting patents to domestic and foreign applications; China appears to give preferential treatment to domestic applications. Such practices have implications for both patenting policy and activities. 相似文献

We examine the diversification of administrative and procedural costs on patent stock using a large dataset from the European Patent Office with 15,000 firms for the period between 1995 and 2015. The results reveal that administrative and procedural costs are significant for firm-level patenting activity. However, not all administrative and procedural costs have equal effects. Higher administrative costs often encourage patent application and validation by solving the adverse selection problem and short-run opportunism, as well as other sources of asymmetric information. The effective administration of intellectual property law and low-cost enforcement are found to considerably foster patenting activity. The effects are robust for various mis-specification checks and do not disappear once country-level research and development infrastructure proxies are controlled for. The extreme bounds of administrative and procedural costs are computed across more than 5 billion regressions, and the sizeable impact of administration on patent application and validation outcomes is confirmed. 相似文献

This paper benchmarks the patent activities of a sample of OECD countries against the world frontier and explores the sources of the cross-country differences in patenting (regarded as a proxy for innovation). A patent production frontier is estimated for a panel of 21 OECD countries over the 1990-2002 period using Stochastic Frontier Analysis. Patenting performance for each country is decomposed into basic patenting capacity and patenting efficiency. The gap between Europe and the world leaders in terms of basic patenting capacity remains substantial with little sign of convergence over the sample period. In terms of patenting efficiency, Japan, Germany and Italy have improved their relative position in recent years. The gap in patenting performance between the UK and the world frontier is due to relative underperformance in both patenting capacity and efficiency in patent production. Institutional factors are found to be significantly associated with the patenting efficiency of an economy. 相似文献

We analyze the impact of accession to the regional patent system established by the European Patent Convention (EPC) on 14 countries that acceded between 2000 and 2008. We look at changes in patenting behavior by domestic and foreign applicants at the national patent offices and the European Patent Office (EPO). We find a strong change in patent filing behavior among foreigners seeking patent protection in the accession states, substituting EPO patents for domestic patents immediately. However, there is no discernible reaction among domestic entities in terms of domestic filings, although we do find some evidence that applicants in accession states increased their propensity to file patents with the EPO post-accession. Inventors in accession countries also increase their patent filings slightly post-accession, both at the EPO and at the national offices. 相似文献

This study investigates empirically whether patents can be signals to financial markets, thus reducing problems of asymmetric information. In particular we study how patenting behaviour impacts on the way investors perceive software firms’ growth potential through an increase in the amount invested at the initial public offering (IPO) of firms in the US and Europe. This study performs regressions on the relationship of patent applications before IPO and the amount of money collected at the IPO, while controlling other factors that may influence IPO performance. We also attempt to account for a potential source of endogeneity problems that can arise for self-selection bias and simultaneity between the number of patent applications prior to going public and the amount of money collected at IPO. We find significant and robust positive correlations between patent applications and IPO performance. The signalling power of patenting is significantly different for US and European companies, and is related to the difficulty in obtaining a signal and its scarcity. An additional patent application prior to IPO increases IPO proceeds by about 0.507% and 1.13% for US and European companies, respectively. Results suggest that a less ‘applicant friendly’ patenting system increases the credibility of patents as signals and their value for IPO investors. 相似文献

Venture capitalists (VCs) fund the development of promising inventions to turn them into marketable innovations. During this development stage portfolio firms are likely to garner even more inventions at least until the product is fully developed. Once the product is fully developed the focus shifts from development to sales so the number of generated inventions should decrease. This behavior implies that VCs are likely to spur invention according to an inverted U-shape over time. We empirically examine whether patent trajectories are consistent with this hypothesized inverted U-shape using a self-collected dataset containing 233 VC-backed firms and a large set of controls operating in Spain. We find that firms’ patenting activity increases after VC investments. This increase is substantially more pronounced the first two years following VC investments, i.e., patent trajectories follow an inverted U-shape over time. Our more demanding specifications suggest that the sharp increase in patenting right after VCs’ investments is caused by a positive treatment effect over and beyond any likely selection effect. Moreover, we defend that the increase in patenting is not just due to the fact that VCs give money so that firms can patent pre-VC inventions, but also to the fact that VCs fund the development of inventions. 相似文献

This paper investigates the relationship between patenting and publication of research results by university faculty members. Our study adds to the limited evidence on this topic with an empirical investigation based on a panel data set for a broad sample of university researchers. Results suggest that publication and patenting are complementary, not substitute, activities for faculty members. This is not consistent with recent concerns regarding deleterious effects of patenting on the research output of faculty members. Average citations to publications, however, appear to decline for repeat patenters, suggesting either a decrease in quality or restrictions on use associated in patent protection. 相似文献

The increased patenting activity of foreign nationals in the United States has been a source of recent concern, and the fear has been expressed that the US is becoming relatively less technologically inventive. This paper investigates some possible causes of the increased foreign patenting activity and also briefly examines the determinants of patent filings by a country's own residents. The countries covered include: Canada, France, West Germany, Japan, the Netherlands, Sweden, Switzerland, the United Kingdom, and the United States.Based on data on patent applications filed and some preliminary regression analysis, the paper finds that the rising foreign patenting activity in the US probably does not reflect increased foreign inventiveness vis-à-vis the US. However, foreign innovativeness may be increasing relative to the US. Over the period 1963 – 1974, the domestic patent base, measured by the number of patent applications filed by nationals in their home countries, has shown little change in any country except for Japan. Rather, multiple patent applications and a greater propensity to patent abroad, induced by the possibilities of exporting, appear to be the sources of the increase in foreign patent applications in the US and also in Japan. 相似文献

This paper extends the line of research attempting to link innovation to economic growth by addressing some unexplored questions. Using global patent data, this paper empirically investigates the importance of both the quantity and quality of innovation on economic growth, controlling for past measures of inventive inputs. Moreover, our research examines how innovation inputs can be translated into per capita growth under the various economic structures and stages of economic development. Based on a sample of 58 countries for the period 1980–2003, our empirical results indicate that countries hosting firms with higher quality patents also have higher economic growth. Furthermore, we have some evidence that those countries that increase the level of patenting also witness a concomitant increase in economic growth. 相似文献

In this paper, we present a formulation and case studies of the conditions for patenting content-based retrieval processes in digital libraries, especially in image libraries. Inventors and practitioners demand a formulation of the conditions for patenting data-processing processes as computer-related inventions in the form of computer programs. A process for content-based retrieval often consists of a combination of prior disclosed means and also comprises means for parameter setting that is adjusted to retrieve specific kinds of images in certain narrow domains. We focus on requirements for technical advancement (nonobviousness) in the combination of data-processing means, i.e., processes and specification (enablement) on the means for parameter setting in computer programs. Our formulation follows the standards of patent examination and litigation on computer-related inventions in the US. We confirm the feasibility and accountability of our formulation by applying it to several inventions patented in the US. 相似文献

Prior art patent citations have become a popular measure of patent quality and knowledge flow between firms. Interpreting these measurements is complicated, in some cases, because prior art citations are added by patent examiners as well as by patent applicants. The U.S. Patent and Trademark Office (USPTO) adopted new reporting procedures in 2001, making it possible to measure examiner and applicant citations separately for the first time. We analyzed prior art citations listed in all U.S. patents granted in 2001-2003, and found that examiners played a significant role in identifying prior art, adding 63% of citations on the average patent, and all citations on 40% of patents granted. An analysis of variance found that firm-specific variables explain most of the variation in examiner-citation shares. Using multivariate regression, we found that foreign applicants to the USPTO had the highest proportion of citations added by examiners. High-volume patent applicants had a greater proportion of examiner citations, and a substantial number of firms won patents without listing a single applicant citation. In terms of technology, we found higher examiner shares among patents in electronics, communications, and computer-related fields. Taken together, our findings suggest that firm-level patenting practices, particularly among high-volume applicants, have a strong influence on citation data and merit additional research. 相似文献

The valuation of patents is an important, albeit challenging task. Extant research to identify patent value indicators has so far relied on expert estimates of patent value, exploited patent renewal data, or depended on more indirect measures of patent value. Recently, specialized market places for patent transactions have emerged that allow us for the first time to directly observe patent's private value. One of the most prominent market places for patents is Ocean Tomo, a platform that offers periodical patent auctions. We make use of this auction data to empirically test predictions on patent value identifiers on real-world auction prices. We find empirical support for forward citations and the patent's family size; however, both indicators explain only a small variance in patent value. In contrast, our full model explains a large share of variance, making us optimistic that with increased directly observed patent value, such models can be useful tools in patent valuation. 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
