MARPAT® - The CAS Markush database containing the keys to generic substances in patents

Benefit to you

When you need comprehensive maximum recall for your structure searches of chemical patents, you need MARPAT - the structure-searchable database of generic, hypothetical substances found in patent claims and disclosures.

Content

MARPAT, produced by CAS, contains:

  • More than 830,000 searchable Markush structures from patents covered by CAS from 1961 to the present - 11/10
  • More than 330,000 displayable citations for the Markush structure-containing patents - 12/09
  • Records from 1961-1987 derived from INPI data
  • Displayable information includes bibliographic data, abstract, and CAS indexing

Coverage

  • All countries whose patent offices are covered in the CA file are candidates for MARPAT indexing.  As of 2009, MARPAT now includes Korea.
  • Not included: Alloys, metal oxides, inorganic salts, intermetallics, and polymers

Update frequency

  • Updated daily with approximately 60-75 patent citations and 150-200 Markush structures
