At the PIUG Meeting in Princeton recently, the issue came up of
what do Derwent's Polymer Indexers use for indexing, the original
specification or Derwent's detailed Documentation Abstracts. In
fact, Indexing is done from both. Indexers use the Doc Abs for
the gist of the patent, and the original specification for the
detailed indexing.
Indexing coverage is explained in the 'Polymer Indexing System
Description' Edition 2 June 1996 page 3. Indexing is based on
the patent specification and all the claims, claim-related
examples, and information from the documentation abstract. (This
is an update on I.M.4A-p2.) You will note that both coverage
notes include information from the claims.
We have always considered the claims as being of paramount
importance.
I apologize for any confusion or consternation.

Don,
I have a question and concern about from which
document(s) Derwent indexes polymers. If I am not mistaken, you
said at the PIUG workshop that the indexing is done from the
Documentation Abstracts. I checked manual 4a and the Enhanced
System description and both indicate that "subject matter from
the patent and the Derwent Doc. Abs. is indexed...information
indexed must include all claims, objects, examples, and
applications of polymers...Additional information from the body
of the patent, where it is judged to be significant, is also
indexed." (I.M.4A-p.2) I understand that Japanese and USSR
patents are indexed from the Doc Abs due to language
difficulties. I am, however, quite concerned about the others.
I appreciate your time to explain this policy to me.
Heather Smith
