Nanotechnology: Its Delineation in Terms of Journals and Patents -- preprint version available

[Boyack, Kevin W]

Dear Loet,
 
Thanks for continuing to post your work as it becomes available. I very
much enjoy keeping up to date on your work.
 
In scanning through this paper, I thought I might make a point that
could be of interest to those on this list that work with patent data.
Your paper shows the lead position of "The Regents of the University of
California" in the USPTO class 977 patents (nano). You correctly state
that this includes all of the various branches of the University of
California (Berkeley, SF, SD, SB, LA, Davis, Riverside, Irvine, Santa
Cruz, Merced). But what many people may not know is that there are three
other institutions that also patent under the "UC" umbrella, and in some
cases these institutions dominate the university component. They are:
 
Los Alamos National Laboratory
Lawrence Livermore National Laboratory
Lawrence Berkeley Laboratory
 
All three institutions, although US Department of Energy labs, have the
UC as their GOCO (government-owned contractor-operated) prime
contractor, and patent under the UC umbrella (in most, but not all,
cases). The best way to differentiate these patents from the true
university patents is to look for the government contract number in the
"government information" field, which, unfortunately, is no longer
included in the weekly XML front page files on the USPTO weekly update
site. The prime contract for Los Alamos was recently awarded to a
Bechtel consortium (with some UC involvement). Whether or not the Los
Alamos patents will appear under Bechtel or LANL or ??? in the future
remains to be seen. 
 
Regarding the splitting out of UC patents to the various university
locations - good luck. I have done it for one small project, and the
best way I found was to use Google Scholar to find a recent paper by the
inventor(s) to get a university address. Use of inventor city and state
is not definitive in this case, because there are five institutions in
the SF Bay area (UCSF, UCB, UCSC, LLNL, LBL) and three in the greater
Los Angeles area (UCLA, UCI, UCSB). 
 
I hope this information is useful to someone.
 
Best wishes,
Kevin

The Journal Citation Reports of the Science Citation Index 2004 were
used to delineate a core set of nanotechnology journals and a
nanotechnology-relevant set. In comparison with 2003, the core set has
grown and the relevant set has decreased. This suggests a higher degree
of codification in the field of nanotechnology: the field has become
more focused in terms of citation practices. Using the citing patterns
among journals at the aggregate level, a core group of ten
nanotechnology journals in the vector space can be delineated on the
criterion of betweenness centrality. National contributions to this core
group of journals are evaluated for the years 2003, 2004, and 2005.
Additionally, the specific class of nanotechnology patents in the
database of the U.S. Patent and Trade Office (USPTO) is analyzed to
determine if non-patent literature references can be used as a source
for the delineation of the knowledge base in terms of scientific
journals. The references are primarily to general science journals and
letters, and therefore not specific enough for the purpose of
delineating a journal set.
