Patents from Asian countries continue to be the leading source of chemistry disclosures
Columbus, Ohio (6 December 2012) – Chemical Abstracts Service (CAS), the world’s authority for chemical information, announced today a major milestone for the CAS REGISTRYSM, the largest collection of publicly disclosed chemical substance information. CAS scientists registered the 70 millionth substance from a patent application submitted to the Korean Intellectual Property Office (KIPO).
The 70 millionth substance is a potential T-type calcium channel blocker discovered at the Korea Institute of Science and Technology (KIST), a multidisciplinary research institute in Seoul, South Korea. Assigned CAS Registry Number® 1411769-41-9, the substance is one of several pyrazolyl-piperazine compounds disclosed in the patent application published by KIPO on November 14, 2012. This molecule may be useful in the treatment of epilepsy, Parkinson’s disease, dementia and other conditions.

“It’s exciting that this milestone was realized with a substance from a Korean patent considering our earlier reports that Asian scientists are disclosing more chemical research in patents,” said Christine McCue, Vice President of marketing at CAS. “This year alone, 63 percent of all chemical patents covered by CAS originated in Asia. Our team of scientists analyzes documents in more than 50 languages, including more than 20 Asian languages, and is uniquely qualified to uncover important chemistry patented by scientists worldwide.”
Similar to the 60 millionth substance registered in May 2011, the 70 millionth substance again reflects the value of patents as an important source of chemical information. In fact, more than 70 percent of new substances from the literature registered in 2012 originated from patents. To ensure the completeness and quality of the CAS premier substance collection, CAS scientists analyze, organize and curate chemistry in patents from 63 patent authorities around the world, far more than any other service.
