The Driving Force
» Chemical structure search
requested by end users
» Debate on the searchability of INNs
in WIPO's SCP (Standing
Committee on the Law of Patents) 1)
» The project can act as a proof of
concept
» Good progress and availability of
related open source tools allowing us
to envisage a solution affordable by
WIPO (OPSIN, OSRA)

The Project at a Glance: Addition of Chemical Search
Capabilities to the WIPO PATENTSCOPE Search System
» Project PTD/14/076,
▪ Phase 1: July 2015 – Feb. 2016
▪ Phase 2: July 2016 – Dec. 2016
» Chemical annotation of PATENTSCOPE full-text
documents using InfoChem’s ICANNOTATOR
» Chemical image recognition in PATENTSCOPE
documents using multiple I2S tools
» Extension of the PATENTSCOPE GUI with chemical
structure search
» 2017: Project RFI GIS/17/039
▪ Processing of EPO collection
▪ Extension to Chinese, Korean, Japanese, Russian
▪ Substructure Search

Pre-selection of Documents by IPC code
» 37 IPC codes were selected in an iterative process using automatic annotation and
chemistry knowledge

Approach
» Development a proprietary Russian chemical
annotator for ‚Rospatent‘
» Annotation of Korean, Chinese and Japanese
documents using
▪ ChemNameTranslate by NextMove Software
for the initial translation of systematic names
▪ Proprietary dictionaries for trade, brand and
trivial names including WIPO machine
translated names
▪ Various filters to reduce the number of false
positive annotations
» Quantitative QA: chemists (native speakers):
analysis of FP and FN annotations
▪ KO: 14 patents, 2,941 annotations
▪ CN: 15 patents, 3,916 annotations
▪ JP: 13 patents, 4,352 annotations
▪ RU: 12 patents, 18,237 annotations

First, the goal to improve
the searchability of INNs
in patent information is
fully achieved:
Example Ritonavir

Second, you can combine a chemical search with any other criteria using
boolean logic:
Theobromine is found in the seeds of the plant Theobroma Cacao, which is the
well-known source of chocolate and cocoa. It has a bitter flavor, which gives
dark chocolate its typical bitter taste. Its chemical formula is C7H8N4O2 and
IUPAC name: 3,7-dimethyl-1H-purine-2,6-dione (source wikipedia)
Let us search patent applications using theobromine...

38 / 44

39 / 44

40 / 44
Now, we would like to focus on the PCT patent applications where the invention
cites Theobromine and is about chocolate:
» CHEM:(YAPQBXQYLJRXSA-UHFFFAOYSA-N)
» AND CTR:WO
» AND EN_AB:chocolate

» A very successful project
» Key success factors:
» Step by step approach
» The right expectations
» The right compromises
» The right team combination
