Merged Markush Service (MMS) - Chemistry

The Merged Markush Service (MMS) is an extensive patent information service for searching markush chemical structures in patents.
Read our latest news...

The information in the databases that compose MMS is indexed by two prestigious organizations:

  • INPI, Institut National de la Propriete Industrielle, the French Patent & Trademark Office AND
  • The Thomson Reuter Corporation, which has been supplying value-added patent information worldwide to patent professionals for over 40 years.

MMS includes both generic and specific chemical structures, including chemical structures from the Derwent Chemistry Resource (DCR). In an MMS search, compound numbers are retrieved and transferred to both the Derwent World Patent Index and the PHARMSearch file available on Questel.

MMS is exclusively available through Questel. No special subscription is required to access MMS; only a Questel ID. MMS can be accessed using the Questel Imagination software. Pricing for MMS appears in the Questel price list.

 

MMS Coverage

MMS covers pharmaceutical patents back to 1978 and chemical patents from Derwent sections C & E back to 1982. There is an additional segment of French Pharmaceutical Patents (BSM) from 1961 to 1976. The following chart illustrates the MMS coverage.

Testimonials

"I consider it absolutely essential to search Questel’s MMS database as part of a thorough markush chemical structure search.  I often retrieve unique structures from MMS not found elsewhere.”
