Thanks, Kevin. It is interesting and I 'll add a footnote about this in the
next version!

Best wishes,  Loet

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

Its Delineation in terms of Journals  <http://www.leydesdorff.net/nano06>

Loet Leydesdorff and Ping Zhou

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.
