Markush structures are representations of chemical structure used to indicate a group of related chemical compounds commonly located in patent claims and descriptions, and are key resources in intellectual property searching, such as patentability, Freedom to Operate, and validity searches. MARPAT, CAS’s source of Markush structures from patents and patent applications, recently achieved two milestones – it is now 30 years old and contains more than 500,000 patent records. An analysis of the Markush disclosures in MARPAT over time, the changes in complexity and diversity, and commercial domains covered will be presented.<br/>
