What patents does CAS cover?
CAS indexes chemical patents from around the world. Its coverage is both thorough and timely. To see information about this coverage and interpreting patent records retrieved in SciFinder, see CAS’ Patent Coverage web pages. While CAS does cover chemical patents very well, the SciFinder interface is not designed or recommended for comprehensive patentability (prior art) searching, which should be done by experienced patent searchers using specialized databases. And remember that the academic usage terms prohibit using SciFinder for any profit-making purpose, regardless of one’s academic status.
