Derwent World Patents Index (DWPI)
A multi-stage Boolean search strategy
• Create main search terms - a variety of DSSC technical terminology
• Enrich those search terms - different expressions of DSSCs
-closely related technical structures.
• Check search terms
-excluding their retrieval overlap with the main search.
• Combine the terms and evaluate them -randomly testing and assessing retrieval results
• Further revise our search terms
Data cleaning – Vantagepoint software
3079 records from 1991-2010 on DSSCs

R&D analysis
• Extract keywords and classify them
I. Determine which phrases refer to the component technologies
II. Extract keywords which are near those component-related phrases are extracted from the patent abstracts and claims
III. Select those actually technically related keywords with experts
IV. Merge phrases that refer to the same thing.
V. Classify them according to experts’ opinion

Competitive analysis• Green nodes – assignees
• Yellow nodes – technologies
•Lines link assignees and technologies if they coincide in patents.
•Thickness of lines represents occurrences—thicker lines represent a higher count of occurrences.
• Most of the organizations are Japanese companies
• Three Chinese organizations: CASX, CHSC, and IRIC
•CASX - organic dye & gel electrolyte
•CHSC - carbon counter-electrode
• IRIC - platinum counter-electrode & TiO2.

China’s challenges on DSSCs
• Japan and South Korea is the most potential competitive in future market and is on the way of commercialization
• China still has a long way to go for significant commercialization of DSSCs globally
• It is important to encourage more companies to become involved in DSSCs.
• China might also consider ways to promote collaboration between companies and academic institutions.

Tips
• This research implements a special in-depth analysis on DSSCs’ component technologies rather than more “macro” analyses.
•The keywords selection and classification is challenging but benefits from inputs by knowledgeable colleagues.
•It is important to carefully identify technology morphology with experts according to the purpose of that analysis.
