Impact of Substances in Patents on CAS Registry

04-Dec-2002
Chemical Abstracts Service (CAS) reports that more than 50% of the organic and inorganic chemical substances recorded in the CAS Chemical Registry System during 2002 were derived from patent documents as opposed to journal literature and other publications. This finding highlights a trend evident since at least 1998 in which an increasing percentage of substances of this type have been reported for the first time in patents. CAS made the announcement during the Online Information 2002 conference being held this week in London. "It is already widely recognized that patents provide a wealth of chemical information, and CAS databases contain information on more than 8 million patents back to 1907," said CAS Editorial Operations Director, Dr. Matthew J. Toussant. "For three years we have watched a developing trend that we have now concluded is an actual sea change, with the number of chemical substances disclosed for the first time in patent documents now amounting to a majority of the substances added to the CAS Registry year after year." CAS registers substances of all types as they are newly reported and come to the attention of CAS scientists who analyze and index patents from 37 issuing authorities, articles from over 9000 scientific journals, books, and other documents published around the world.
