Patents and clean energy

Bridging the gap between evidence and policy

A joint study by the United Nations Environment Programme (UNEP), the European Patent Office (EPO) and the International Centre for Trade and Sustainable Development (ICTSD) on the relationship between patents and the development and transfer of clean-energy technologies has yielded important insights, evidence and data which could lead to better-informed policy-making on this important subject.

The study's final report includes the findings from a comprehensive mapping of clean energy technologies, an in-depth analysis of the patent landscape for these technologies, and a survey of licensing activities in this field.


The final report was presented in Brussels on 30 September 2010.

New patent classification scheme

One groundbreaking result of the project has been the creation of a dedicated classification scheme for patent documents relating to clean-energy technologies, which is now online. Using a searchable database, this new scheme gives users access to up-to-the-minute, accurate and user-friendly patent information.
