7.5 What chemical patent information is available on-line?
Both Dialog and STN offer commercial access to US and International patents
online, many with full text - however the international ones, especially
those devoted to capturing the current status of patents can be expensive,
so ensure your searching skills are honed if you wish to avoid a large
bill.

http://www.patents.ibm.com/
A new site that offers free searching of the last 20+ years of US
patents, and also provide the abstracts, some images, and the claim
summary free. Complete copies of the patents can also be ordered.
It has a good search engine, and probably should be the first site to
visit, but note that it requires a browser that supports frames
(eg version 3 of Netscape or Internet Explorer).

Gregory Aharonian has struggled for several years to provide a free,
comprehensive patent title service. This excellent free service offers
the titles of chemical, mechanical, or electrical patents via email
to subscribers. Recently he also offered one years worth of patent
abstracts, but requires some financial donations to expand the
service. The abstracts are freely retrievable by patent number (sorry
no searching yet, that needs the big donations). For subscription info,
send 'help' to patents@world.std.com.

This page provides access to both the U.S. Patent Bibliographic
Database, which includes bibliographic data from 1976 to 1997, and
the AIDS Patent Database, which includes the full text and images
of AIDS related patent issued by the U.S., European and Japanese
Patent offices.
