Derwent Markush Resource now available on the new STN platform!

19. November 2015

Access to the Derwent Markush Resource (file name DWPIM) is available exclusively on the new STN platform. It is implemented as a structure-based database encompassing around 1.9 million Markush structures from around 767.000 Derwent World Patents Index® (DWPIsm) documents. 33 patent issuing authorities are covered whereby for US, EP and WO coverage is starting from 1978 onwards. Included is also INPI (French patent office) backfile data from 1961-1998. The database is updated 82 times a year together with DWPI.

The latest release of the new STN platform delivers MARPAT and the Derwent Markush Resource on a single platform for the first time ever, making new STN the only unified Markush solution that offers chemical patent searchers unsurpassed coverage and highly efficient access to the rapidly growing number of chemical structures disclosed in patents.

The Derwent Markush Resource is available under fixed price conditions only; an amendment to existing fixed fee agreements needs to be in place. For further questions and information, please contact your STN account representative or your STN helpdesk.
