Re: Chemical patent searching sources

I agree with the earlier comments on the scope of this question, but
would like to add one point.
The whole question of "mining" chemical patent information is, for me,
largely a non-issue when it comes to trying to derive information on new
chemical entities. It may have a place when it relates to second-use
patents or mixture/formulation/process technology, but not to my mind
when trying to analyse first disclosures of chemical compounds.
Why do I say this? Simply on the basis that so far, all these mining
tools are based around analysing the text of patent specifications. But
no matter how good the *text* mining/analysis software, it is not going
to generate meaningful results all the time that a very large percentage
of the disclosure in the patents is in the form of *non-text* material,
i.e. specific or generic structures. Suggesting that you can get this
information easily by algorithmic text-based methods is akin to the
suggestion of 20 years ago that you could do a comprehensive chemical
search using systematic nomenclature. We may have believed it once,
before sub-structure search systems arrived, but never again!
