According to this report, six countries – Japan, USA, Germany, Korea, France and the UK – are the source of almost 80% of all innovations developed worldwide in the field of clean energy technologies (CETs). This is one of the key findings of a patent-based study on the emergence and distribution of these technologies across the globe jointly conducted by the European Patent Office (EPO), the United Nations Environment Programme (UNEP) and the International Centre for Trade and Sustainable Development (ICTSD).
The study shows clearly that the surge of patenting activity in CETs coincided with the adoption of the Kyoto Protocol in 1997, providing a strong indication that political decisions can be important in creating a framework to stimulate the development of technologies which are considered to be crucial to the efforts to address climate change. The statistical analysis of the data shows that patenting rates in the selected CETs have increased roughly 20% per year since then, outpacing the traditional energy sources of fossil fuels and nuclear energy.
The report also mentions that China is rapidly gaining ground in the number of cleanip patent filings. I suspect, however, that many of these patents originating from China have a relatively low patent quality, as discussed in this post on solar patent quality.
