"Intellectual
analysis and the thorough indexing of our scientists far
surpass robotic means of identifying relevant research
publications," said CAS Vice President, Editorial Operations,
Dr. Matthew J. Toussant. "This is especially critical in
finding the new science disclosed in patents. Our scientists
look at descriptive information and translate it into
substance records that can be searched by structure in our STN
and SciFinder services. None of the free web services can
provide this unique value added link to the literature and
patents."
 The
Primacy of Patents
As in previous years, new substance
records entering the CAS Registry database in 2004 were
derived from CAS analysis of both journal articles and
patents. However, the share of new substances contributed by
patents grew to 60 percent for the year. During 2004, CAS
enriched its database content in several ways:
 |
Patents grew as a
percentage of CAS database content; indexed patents and
related CAS patent family records now amount to more
than 20 percent of the total;
|
|
Additional patents of
scientific interest beyond chemistry and not originally
covered in CA are now being added, and will amount to
thousands of new records;
|
|
|
Recent
publications represented in CAS databases are complemented by
millions of older documents back to 1900, digitised for its
Scientific Century project. Visit here
