This document discusses using the new STN platform to conduct a patent search on artemisinin, a drug used to treat malaria. It provides steps to draw the chemical structure of artemisinin, search for it and related terms in databases like CAS REGISTRY and Derwent World Patents Index, extract chemical names from results, and filter by specific countries of interest. The search retrieves over 200 relevant records across multiple databases. The document also outlines the STN Global Value Pricing model.
