Towards simplified access to chemical structure information in the patent literature

This paper addresses the problems associated with chemical structure searching of the patent literature. The deficiencies of existing services are reviewed, and the results of continuing research aimed at overcoming these problems are presented. These take the form of a systematic structure description language (GENSAL) for generic structure input, a topological representation of generic structure (ECTR) suitable for ma chine processing, and algorithmic screening strategies for generic structure searching and retrieval.
