Online search tool for CET patent documents

摘要

The European Patent Office (EPO) has created a free, easy-to-use online search tool which provides unrestricted access to all patent documents related to clean energy technologies (CETs) worldwide. The tool improves transparency in the sector by putting some 700,000 patent documents in the CET field at the public's fingertips. The new tool was launched alongside a patent-based study on the emergence and distribution of clean energy technologies (CET) across the globe, jointly conducted by the EPO, the United Nations Environment Programme (UNEP) and the International Centre for Trade and Sustainable Development (ICTSD).
