Organic Photovoltaic: Patent Survey

Seminar TU Eindhoven 22/05/ 2012

Seminar TU Eindhoven22/05/2012

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


Tools

3 databases: Questel : strategy of research, statistics Espacenet : classification identification Derwent : simplified presentation of patents

(classifications, summary, adapted keywords, etc.)

Topics : OPV - General Substrates : paper, zinc, textile, steel, glass Encapsulation Solution processed layers (classification B05-

Applying liquids or other fluent materials to surfaces, in general ) + stability and lifetime

Results: Publication dates

OPV + Glass substrate



Encapsulation



Example: Results for paper as

substrate

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

Results for OPV General search


Results: Top Companies vs Years

Results for OPV + Glass substrate



Results for OPV + Paper substrate



Results for OPV + Textile substrate

The research on textile as substrate started later than the others but is becoming more important


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.


Results OPV General: Assignees vs Concepts


Results Glass: Top Concepts vs Years


Summary

From statistic

The OPV research starts to grow exponentially in 2001

Three types of companies were identified: - Major players in the field of electronic (Samsung, Lg, Sony, etc)

- Major players in the field of chemistry (BASF, Dupont de Nemours, Merck, etc)

- Companies who are present in one field like Kodak

Next Steps

Database

Database updated every 3 months

New researches based on partners needs

DATABASEOPV Patents

Seminar TU Eindhoven 22/05/ 2012


Tools

Tool to collect patents : FamPat (Questel) > development of a specific

strategy to find all the OPV patents and to update the database

Tool to manage patents : FileMaker Pro


Results (26/02/2012)

15.176 OPV patents or records (without limitation)

Possibility of searching by substrates :

Possibility of searching by encapsulation : 2908 patents or records


OPV-Database


Possibility of searching in several fields

Example : By assignee (BASF)


Possibility of searching in several fields Example : By assignee (BASF)


Possibility of searching in several fields Example : by type of substrate (glass)


OPV Database

Update every 3 months

Statistics once a year

Accessible through Internet for all the

Organext Partners (working tool)

Access to full text through Espacenet (free

access) with the patent number
