“…It thus attracts the highest level of competition and is therefore a clear indication of technological capabilities for those who are able to innovate in it. Li et al (2007c) also show that Canadian assignees prefer filing patents in the US rather than the EPO. All granted patents that contain one of these keywords in all their fields and that have been granted to Canadian firms or for which one of the inventors resides in Canada are retrieved from the database.…”

Discovering and assessing fields of expertise in nanomedicine: a patent co-citation network perspective

Document publié chez l'éditeur commercial ABSTRACTDiscovering and assessing fields of expertise in emerging technologies from patent data is not straightforward. First, patent classification in an emerging technology being far from complete, the definitions of the various applications of its inventions are embedded within communities of practice. Because patents must contain full record of prior art, co-citation networks can, in theory, be used to identify and delineate the inventive effort of these communities of practice. However, the use patent citations for the purpose of measuring technological relatedness is not obvious because they can be added by examiners. Second, the assessment of the development stage of emerging industries has been mostly done through simple patent counts. Because patents are not all valuable, a better way of evaluating an industry's stage of development would be to use multiple patent quality metrics as well as economic activity agglomeration indicators. The purpose of this article is to validate the use of 1) patent citations as indicators of technological relatedness, and 2) multiple indicators for assessing an industry's development stage. Greedy modularity optimization of the 'Canadian-made' nanotechnology patent co-citation network shows that patent citations can effectively be used as indicators of technological relatedness. Furthermore, the use of multiple patent quality and economic agglomeration indicators offers better assessment and forecasting potential than simple patent counts.

“…Li et al (2007b) observed that the US filed more nanotechnology patents in both patent offices than any other country in almost every year from 1978 to 2004. They also found that the top 20 countries ranked by the nanotechnology patent applications in the USPTO and EPO are very similar.…”

“…However, a longitudinal analysis of the USPTO patents by Wong et al (2007) indicated that the patent applications from South Korea, Australia and Taiwan have increased rather rapidly after 2000. China's progress in nanotechnology patenting was not as impressive as its performance in producing scientific publications, as the ranking of this country measured through patent applications in USPTO and EPO was around the 20th place (Li et al 2007b;Huang et al 2003).…”

Nanoscience and technology publications and patents: a review of social science studies and search strategies

2010

View full text Add to dashboard Cite

We undertake a comprehensive review of more than 120 social science studies on nanotechnology, 90% of which are based on the analyses of the nanotechnology publications and patents. We discussed four intellectual debates formed by these studies, namely whether nanotechnology is an interdisciplinary field, whether nanoscience and nanotechnology are closely interlinked, whether nanotechnology development is path dependent and who is winning the global nanorace. We also conduct a comparative analysis of bibliometric search strategies used in the literature to harvest the publications and patents, including lexical queries, evolutionary lexical queries, citation analysis, and the use of core journal sets to identify nanotechnology articles. Because most of the compared strategies, except the one using 10 core journals in the field, share a core set of keywords and thus harvest a common batch of publications, they produce very similar ranking tables of the top subject areas and journals and the most prolific countries and institutions. Moreover, the core journal strategy does not provide a robust delineation of an emerging field such as nanotechnology due to the fact that nanotechnology related articles are published in a wide range of journals. Also, the different criteria for selecting the core journals will affect the analytical results dramatically.

“…Under current trends, continued government investment in From Li et al (2007) and Graham and Iacopetta (2009); the table cites data as originally published J Nanopart Res basic and applied R&D combined with general economic recovery will create continued patenting and spin-out growth over the mid-term, despite a short-term shortage of venture capital funding. At the same time, a significant number of nanotechnology patents will be concentrated to a smaller set of actors.…”

Governance of nanotechnology is essential for realizing economic growth and other societal benefits of the new technology, protecting public health and environment, and supporting global collaboration and progress. The article outlines governance principles and methods specific for this emerging field. Advances in the last 10 years, the current status and a vision for the next decade are presented based on an international study with input from over 35 countries.Keywords Nanoscale science and engineering Á Nanotechnology innovation and commercialization Á Responsible development, Global governance, Emerging technologies Á Societal implications Á Ethical and legal aspects Á Nanotechnology market Á Public participation Á International perspective Vision for the next decadeChanges in the vision over the last 10 years Nanotechnology has been defined as ''a multidisciplinary field in support of a broad-based technology to reach mass use by 2020, offering a new approach for education, innovation, learning, and governance' ' (Roco et al. 1999). The governance of nanotechnology development for societal benefit is a challenge with many facets ranging from fostering research and innovation to addressing ethical concerns and long-term human development aspects. The U.S. nanotechnology governance approach has aimed to be ''transformational, responsible, and inclusive, and [to] allow visionary development'' (Roco 2008). Both domestically and globally, the approach to nanotechnology governance has evolved considerably in the last 10 years:• The viability and societal importance of nanotechnology applications has been confirmed, while extreme predictions, both pro and con, have receded.
