Longitudinal patent analysis for nanoscale science and engineering: Country, institution and technology field

Artificial Intelligence Lab, Department of MIS, University of Arizona / 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.
