The investigation comprises information about patent citations distributed by different technological domains, which are used to map knowledge flows and to correlate these flows with the evolution of countries' competences. Specifically, the analysis uses information about patent citations to track and discuss the evolution of knowledge flows to a set of selected countries involved in catching-up up processes.. The analysis comprises an analysis of patent citation data extracted from the USPTO database from the period 1982-2006, including information about citations extracted from patents granted by national companies of the selected countries, presented trough technological interaction matrices crossing information of different technological domains of the patents, correlating the technological domains of the patents citing other patents with the technological domains of the patents cited. The hypothesis is that the intensification and diversification of knowledge flows to a gr...
Technological patterns in the wind power industry: a study based on patent deposits
Production
Paper aims: This paper presents the results of technological analysis on wind energy based on patent documents classified with code F03D-"Wind Motors." Originality: Despite several studies on wind energy, this paper follows a different approach, presenting an overview that brings together technical and market information through social network analysis methods. Research method: The study covered data from 55,223 documents filed in the principal patent offices of the world, obtained from the Derwent Innovations Index. The publications were organized and analyzed through correlation and technology transfer networks. Main findings: General Electric (GE) and European companies have dominated the wind energy industry. However, in the last years, companies from emerging countries are also penetrating and becoming major players. Emphasis can be given to China, which has a deposit pattern detached from the rest of the world. Implications for theory and practice: This study indicates that these companies became important turbine manufacturers and started to invest in developing new technologies and seek patent protection. Companies from emerging countries are new entrants, and their performance is still restricted to few markets compared to traditional companies.
Intra-EU Knowledge Flows in the Renewable Energy Sector: a Patent Citations Analysis
2015
We test whether demand-pull environmental measures, introduced with the 1997 Commission White Paper and following Directives, had an impact on the fragmentation of EU research and innovation effort in the strategic field of renewable energy. By focusing on knowledge spillovers, we study the pattern and evolution of knowledge flows within the EU and between the EU and two frontier innovators: the United States and Japan. This research question is motivated by increased concern that the fragmentation of EU renewable energy research and innovation systems may hamper the ability to address climate challenges at socially acceptable costs. Following a well-established tradition, we measure the intensity and the direction of knowledge flows by looking at patent citations. Our results suggest that after 1997 Member States’ national innovation systems have evolved towards a more integrated innovation space at the EU level. Furthermore, environmental policies seem to have pushed the EU to bec...
Cross-country learning from patents: an analysis of citations flows in innovation trajectories
Scientometrics, 2021
This study proposes a methodological approach to investigate cross-country creativity/knowledge flows by analyzing patent citation networks, taking the aircraft, aviation and cosmonautics (AAC) industry as a case study. It aims at shedding some light on the following research questions: (a) how cross-country creative/learning flows can be investigated; (b) have countries of current patent owners benefited from patent acquisitions. In fact, despite the well-established economic interest for (analyzing and forecasting) innovation trajectories, this research area is still unexplored, thus, motivating the need for such study. Over 43,000,000 patents have been analyzed whereby: (a) owners have performed cross-country patent acquisitions; (b) acquired patents (granted within 2005–2009) are cited by subsequent patents (2010–2015). Methodology and results are scalable to other industries and can be exploited by managers and policy makers to: (a) help firms forecasting innovation trajectorie...
Innovation systems as patent networks
2008
While patent data offers a quantitative measure, they are often used in a rather unimaginative way. Patents granted are aggregated to the level of firms, regions, sectors or countries to determine the respective aggregate’ s (potential)(future) significance. While patent data is Globalisation of knowledge development and delivery, ISID, New Delhi, India, October 17-18, 2008 shaped by institutions, and reflects information about applications that is the result of institutional configurations, they are not defined by institutions a priori. ...
Patent portfolios and knowledge flow(s) of photovoltaic companies
Technology Analysis & Strategic Management, 2016
The current trend towards green energy is encouraging manufacturers to invest in photovoltaic technologies. In order to guarantee R&D and optimal operational performance, operators should be able to identify the technological advantages of their competitors for the conduct R&D and to ensure adequate technological knowledge intake. Therefore, from the perspective of patent portfolios and knowledge flow(s) of photovoltaic companies, this study adopted two approaches namely, patent counts and patent citations, to discuss the technical capability of R&D portfolios and the technological knowledge flow. Three patent indices were utilised for the integration of R&D portfolios which include: technology attractiveness, relative patent position, and revealed patent advantage. Technological knowledge flow allows construction of a patent citation network through backward citation of patents. Sources and movement directions of technological knowledge are measured by calculating the relative citation propensity. R&D portfolios and knowledge flow are complementary perspectives of each photovoltaic company.
Patent portfolios of European wind industry: New insights using citation categories
This study explores the use of citation categories assigned by patent examiners to study overlap of patent portfolios among top wind power firms. Cooperative Patent Classification (CPC) is used to obtain a sample of wind industry patents. CPC is shown to be better than the International Patent Classification for identifying patents relevant to the wind power industry. Results show high inter-firm citation among the top wind industry players that can suggest concentration of innovation. The results can be useful for patent analysts, technology managers and policy makers. Rahul Kapoor* , Matti Karvonen, Samira Ranaei, Tuomo Kassi
Towards Understanding the Role and Value of Patents in a Knowledge-Based Economy
DAAAM International Scientific Book, 2013
Patent, as a form of intellectual property has existed for centuries with the underlying purpose of balancing between the interests of the inventor and those of the society and thus stimulating innovation, research and creativity. For a long time patents were mainly deployed for two fundamental strategic purposes -to sustain exclusion rights or in cross-licensing negotiations with competitors. However, with the entrance of non-producing patent dealers (e.g. Intellectual Ventures, Rambus, Rembrandt IP, Acacia Technologies) to the high technology market, the strategy of "being infringed" has emerged as the new stream in the strategic use of patents. Patent dealers have reached an exceptional growth rate in scale and scope of operations and today they significantly affect companies of all sizes in many industries, not only in the high technology sector. Moreover, the new strategy and new players changed the basic postulates in understanding the use and value of patents. This chapter is intended to review the role of patents in a knowledgebased economy and the various ways patents are used and valued today, to identify emerging trends and to outline the areas where further research is needed.
