Abstract: Academic nanoscale science and engineering (NSE) research 
provides a foundation for nanotechnology innovation reflected in patents. 
About 60% or about 50,000 of the NSE-related patents identified by "full-
text" keyword searching between 1976 and 2004 at the United States Patent 
and Trademark Office (USPTO) have an average of approximately 18 academic 
citations. The most cited academic journals, individual researchers, and 
research articles have been evaluated as sources of technology innovation 
in the NSE area over the 28-year period. Each of the most influential 
articles was cited about 90 times on the average, while the most 
influential author was cited more than 700 times by the NSE-related 
patents. Thirteen mainstream journals accounted for about 20% of all 
citations. Science, Nature and Proceedings of the National Academy of 
Sciences (PNAS) have consistently been the top three most cited journals, 
with each article being cited three times on average. There is another 
kind of influential journals, represented by Biosystems and Origin of 
Life, which have very few articles cited but with exceptionally high 
frequencies. The number of academic citations per year from ten most cited 
journals has increased by over 17 times in the interval (1990-1999) as 
compared to (1976-1989), and again over 3 times in the interval (2000-
2004) as compared to (1990-1999). This is an indication of increased used 
of academic knowledge creation in the NSE-related patents.
