Objectives Identification of all the patents related to the OPV developments Statistics :
Years Countries Assignees Classifications
(examples: C = chemistry; Metallurgy
C07= Organic chemistry
C07F= Acyclic, carboxylic or heterocyclic
compounds containing elements
other than C, H, N, S, Se or Te)
Creation of an easy-to-use database available for all the Organext partners

2001 seems to be the beginning of an exponential increase in the number of published patents for the
OPV field

Results: countries
Example: Results for the General
OPV
For all the researches, the top 5 countries are Japan, USA, China, Korea and World, the first European
country is Germany.

Results: Top Companies
- Three types of companies were identified:
- Major players in the field of electronics (Samsung, Lg, Sony, etc.) They are presents in all the steps of the
entire OPV value chain.
- Major players in the field of chemistry (BASF, Dupont de Nemours, Merck, etc.)
- Few companies are presents in one field like Kodak well-known for their knowledge in printing

Other Results
Statistics have been obtained about: Concepts (defined by Questel from the International
classification) Assignees vs concepts Concepts vs years
=> Major trends are the same as described previously, the big companies involved in the OPV field work on all the value chain parts, from the materials to the final device.
