Derwent Chemistry Resource
Derwent Chemistry Resource (DCR) offers structure searching and various other substance identification and indexing data of the chemical structures indexed from update 199916 forward within Derwent World Patents Index® (DWPISM) and the Derwent Drug File (DDF).
For patents included in DWPI, DCR includes:
- All claimed compounds.
- At least the main (best) example. If there are few claimed compounds, more examples are selected.
- For compounds outside the claims, priority of selection is given to real compounds (i.e., those with good supporting physical and/or biological data).
- Where compounds are selected from a range of examples, those that best illustrate the structural diversity of patent coverage are selected.
Derwent Chemistry Resource includes biological, organic, organometallic and inorganic compounds.
Derwent Chemistry Resource cites chemical structures from the more than one million patents classified in Derwent Sections B, C and E (Pharmaceuticals, Agrochemicals and General Chemistry).
The INPADOC/Family and Legal Status database is produced by the European Patent Office (EPO) and describes patents issued by 101 countries and patenting organisations. The International Patent Documentation Center (INPADOC) was formed in 1972 with the support of the World Intellectual Property Organisation (WIPO) to provide a centralised bibliographic source for patent documents. INPADOC is now part of the European Patent Documentation System operated by the European Patent Office (EPO).
