Abstract:
Nanoscale science and engineering (NSE) have seen rapid growth and expansion
in new areas in recent years. This paper provides an international patent
analysis using the U. S. Patent and Trademark Office (USPTO) data searched
by keywords of the entire text: title, abstract, claims, and specifications.
A fraction of these patents fully satisfy the National Nanotechnology
Initiative definition of nanotechnology (which requires exploiting specific
phenomena and direct manipulation at the nanoscale), while others only make
use of NSE tools and methods of investigation. In previous work we proposed
an integrated patent analysis and visualization framework of patent content
mapping  for the NSE field and of knowledge flow pattern identification
until 2002. In this paper, the results are updated for 2003, and the new
trends are presented.

The number of USPTO patents originated from all countries that include
nanotechnology-related keywords in 2003 is about 8600, an increase of about
50% over the last 3 years, which is significantly larger than the increase
of about 4% for patents in all technology fields (USPTO, 2004). The top five
countries are U. S. (5228 patents in 2004), Japan (926), Germany (684),
Canada (244) and France (183). Fastest growing are the Republic of Korea (84
patents in 2003) and Netherlands (81). For the first time in 2003, four
electronic companies have reached the top five institutions: IBM (198
patents), Micron Technologies (129), Advanced Micro Devices (128), Intel
(90) and University of California (89). However, overall, the single
technology field "Chemistry: molecular biology and microbiology'' and
chemical industry remain in the lead. The citation networks show an increase
of international interactions, and a relative change of the role of various
countries, institutions and technological fields in time.
