This paper presents the development of nanotechnology between 2000 and 2016 as reflected in the Web of Science papers, United States Patent and Trademark Office (USPTO), World International Property Organization (WIPO) patents, and National Science Foundation (NSF) awards, with a special reference to the United States (US), European Union (EU27), P.R. China, Japan, and South Korea. The field of nanotechnology is branching out into novel scientific and technology platforms, and it is increasingly difficult to separate foundational nanoscale components from divergent application areas. The average global growth rate has been sustained at about 15% for both papers and patents in the selected interval. The growth rates among regions are non-uniform. P.R. China and South Korea have increased faster in both the numbers and quality of their scientific publications, and currently P.R. China has the largest volume of nanotechnology publications and South Korea the most publications per capita in the field of nanotechnology. The US, EU27, and Japan are maintaining leadership in the upstream, better cited, conceptual components of nanotechnology research and development. 相似文献

This article examines the relative positions with respect to nanotechnology research publications of the European Union (EU),
the United States (US), Japan, Germany, China, and three Asian Tiger nations (South Korea, Singapore, and Taiwan). The analysis
uses a dataset of nanotechnology publication records for the time period 1990 through 2006 (part year) extracted from the
Science Citation Index obtained through the Web of Science and was developed through a two-stage modularized Boolean approach.
The results show that although the EU and the US have the highest number of nanotechnology publications, China and other Asian
countries are increasing their publications rapidly, taking an ever-larger proportion of the total. When viewed in terms of
the quality-based measure of citations, Asian nanotechnology researchers also show growth in recent years. However, by such
citation measures, the US still maintains a strongly dominant position, followed by the EU. 相似文献

Worldwide nanotechnology development: a comparative study of USPTO,EPO, and JPO patents (1976–2004) 总被引:1,自引:0,他引:1
To assess worldwide development of nanotechnology, this paper compares the numbers and contents of nanotechnology patents
in the United States Patent and Trademark Office (USPTO), European Patent Office (EPO), and Japan Patent Office (JPO). It
uses the patent databases as indicators of nanotechnology trends via bibliographic analysis, content map analysis, and citation
network analysis on nanotechnology patents per country, institution, and technology field. The numbers of nanotechnology patents
published in USPTO and EPO have continued to increase quasi-exponentially since 1980, while those published in JPO stabilized
after 1993. Institutions and individuals located in the same region as a repository’s patent office have a higher contribution
to the nanotechnology patent publication in that repository (“home advantage” effect). The USPTO and EPO databases had similar high-productivity contributing countries and technology fields with large number of
patents, but quite different high-impact countries and technology fields after the average number of received cites. Bibliographic analysis on USPTO and EPO patents shows that researchers in the United States and Japan published larger numbers
of patents than other countries, and that their patents were more frequently cited by other patents. Nanotechnology patents
covered physics research topics in all three repositories. In addition, USPTO showed the broadest representation in coverage
in biomedical and electronics areas. The analysis of citations by technology field indicates that USPTO had a clear pattern
of knowledge diffusion from highly cited fields to less cited fields, while EPO showed knowledge exchange mainly occurred
among highly cited fields. 相似文献

Nanotechnology research has experienced rapid growth in recent years. Advances in information technology enable efficient
investigation of publications, their contents, and relationships for large sets of nanotechnology-related documents in order
to assess the status of the field. This paper presents the development of a new knowledge mapping system, called Nano Mapper
(), which integrates the analysis of nanotechnology patents and research grants into a Web-based platform. The Nano Mapper
system currently contains nanotechnology-related patents for 1976–2006 from the United States Patent and Trademark Office
(USPTO), European Patent Office (EPO), and Japan Patent Office (JPO), as well as grant documents from the U.S. National Science
Foundation (NSF) for the same time period. The system provides complex search functionalities, and makes available a set of
analysis and visualization tools (statistics, trend graphs, citation networks, and content maps) that can be applied to different
levels of analytical units (countries, institutions, technical fields) and for different time intervals. The paper shows important
nanotechnology patenting activities at USPTO for 2005–2006 identified through the Nano Mapper system. 相似文献

This article contributes to the growing study on the interactions between science and technology with China’s evidence in
the field of nanotechnology, based on the database of United States Patent and Trademark Office. The analysis is focused during
the period of 1991–2008, a rapid increasing period for the development of nanotechnology. Using the non-patent references
cited by patents, we first investigate the science–technology connections in the context of Chinese nanotechnology, especially
in institutional sectors and its application fields. Those patents, produced by academic researchers and directed towards
basic scientific knowledge, generally cite more scientific references with a higher proportion of self-citations. It is interesting
to find that patents contributed by collaborations between public organizations and corporations seldom contain scientific
references. Following an interesting path on matching the data of publications and patents, we establish the author-inventor
links in this emerging field. Author-inventors, who are co-active in publishing and patenting, are at the very top of the
most prolific and highly cited researchers. Finally, we employ social network analysis to explore the characteristics of scientific
and technological networks generated by co-authorship and co-invention data, to investigate the position and the role of patenting–publishing
scientists in these research networks. 相似文献

The patent citation networks are described using critical node, core network, and network topological analysis. The main objective
is understanding of the knowledge transfer processes between technical fields, institutions and countries. This includes identifying
key influential players and subfields, the knowledge transfer patterns among them, and the overall knowledge transfer efficiency.
The proposed framework is applied to the field of nanoscale science and engineering (NSE), including the citation networks
of patent documents, submitting institutions, technology fields, and countries. The NSE patents were identified by keywords
“full-text” searching of patents at the United States Patent and Trademark Office (USPTO). The analysis shows that the United
States is the most important citation center in NSE research. The institution citation network illustrates a more efficient
knowledge transfer between institutions than a random network. The country citation network displays a knowledge transfer
capability as efficient as a random network. The technology field citation network and the patent document citation network
exhibit a␣less efficient knowledge diffusion capability than a random network. All four citation networks show a tendency
to form local citation clusters. 相似文献

Nanoscale science and engineering (NSE) and related areas have seen rapid growth in recent years. The speed and scope of development in the field have made it essential for researchers to be informed on the progress across different laboratories, companies, industries and countries. In this project, we experimented with several analysis and visualization techniques on NSE-related United States patent documents to support various knowledge tasks. This paper presents results on the basic analysis of nanotechnology patents between 1976 and 2002, content map analysis and citation network analysis. The data have been obtained on individual countries, institutions and technology fields. The top 10 countries with the largest number of nanotechnology patents are the United States, Japan, France, the United Kingdom, Taiwan, Korea, the Netherlands, Switzerland, Italy and Australia. The fastest growth in the last 5 years has been in chemical and pharmaceutical fields, followed by semiconductor devices. The results demonstrate potential of information-based discovery and visualization technologies to capture knowledge regarding nanotechnology performance, transfer of knowledge and trends of development through analyzing the patent documents. 相似文献

Text mining is the extraction of useful information from large volumes of text. A text mining analysis of the global open nanotechnology literature was performed. Records from the Science Citation Index (SCI)/Social SCI were analyzed to provide the infrastructure of the global nanotechnology literature (prolific authors/journals/institutions/countries, most cited authors/papers/journals) and the thematic structure (taxonomy) of the global nanotechnology literature, from a science perspective. Records from the Engineering Compendex (EC) were analyzed to provide a taxonomy from a technology perspective.
- The Far Eastern countries have expanded nanotechnology publication output dramatically in the past decade.
- The Peoples Republic of China ranks second to the USA (2004 results) in nanotechnology papers published in the SCI, and has increased its nanotechnology publication output by a factor of 21 in a decade.
- Of the six most prolific (publications) nanotechnology countries, the three from the Western group (USA, Germany, France) have about eight percent more nanotechnology publications (for 2004) than the three from the Far Eastern group (China, Japan, South Korea).
- While most of the high nanotechnology publication-producing countries are also high nanotechnology patent producers in the US Patent Office (as of 2003), China is a major exception. China ranks 20th as a nanotechnology patent-producing country in the US Patent Office.

Nanotechnology patent applications published during 1991–2008 have been examined using the “title–abstract” keyword search
on esp@cenet “worldwide” database. The longitudinal evolution of the number of patent applications, their topics, and their respective
patent families have been evaluated for 15 national patent offices covering 98% of the total global activity. The patent offices
of the United States (USA), People’s Republic of China (PRC), Japan, and South Korea have published the largest number of
nanotechnology patent applications, and experienced significant but different growth rates after 2000. In most repositories,
the largest numbers of nanotechnology patent applications originated from their own countries/regions, indicating a significant
“home advantage.” The top applicant institutions are from different sectors in different countries (e.g., from industry in
the US and Canada patent offices, and from academe or government agencies at the PRC office). As compared to 2000, the year
before the establishment of the US National Nanotechnology Initiative (NNI), numerous new invention topics appeared in 2008,
in all 15 patent repositories. This is more pronounced in the USA and PRC. Patent families have increased among the 15 patent
offices, particularly after 2005. Overlapping patent applications increased from none in 1991 to about 4% in 2000 and to about
27% in 2008. The largest share of equivalent nanotechnology patent applications (1,258) between two repositories was identified
between the US and Japan patent offices. 相似文献
