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.
