ChemAxon - Thomson Reuters

Markush project history

1987 Thomson Scientific (Derwent) starts indexing Markush structures

(in collaboration with Questel & INPI)

1998 INPI & Derwent Markush databases merge to form MMS

(Merged Markush Service)

2000 ChemAxon launches first version of JChem Base

2005 Chemaxon starts working on Markush technology

2008 Markush search & enumeration first release in JChem 5.0

2010 Markush DARC file format support in JChem 5.3

2012 Full MMS searchable with JChem 5.5-5.11

Search the Full Patent Database

• Complete patent database from Thomson Reuters dated back

to 1987

– VMN (Markush structures)

– DCR (Exemplified structures)

– DWPI text (non-structural information)

• Data stored in Amazon Cloud with Powerful virtual machine,

secure connection and confidential search

• Useful new features:

– Export exemplified structures

– Retrieve patent document

– Enumerate Markush structures and output result

– Notation

• Batch search of multiple queries

• Constantly improving search performance
