The CAS Markush Search Service database contains the Markush structure records for patents cited in the CA file. Because a typical Markush structure represents more than 250 hypothesized substances, the database offers more than 70 million opportunities to retrieve relevant patents. Sources include patents from 33 national patent offices, EPO, and WIPO. Structures are searchable and displayable. Bibliographic information, patent family information, cited references for records added to the database from 1999 to the present,  abstracts, and indepth substance and subject indexing of the original CA file record are displayable. A learning file, LMARPAT, is available.
