Green Tech Global Challenges Report

The World Intellectual Property Organization (WIPO) published the Global Challenges Report on June 11, 2014. The study deals with the climate change as one of the biggest global challenges of our time. Therefore, the study analyzes the patent landscapes of four Climate Change Mitigation Technologies (CCMTs): Biofuels, solar thermal, solar photovoltaic (PV) and wind energy. The study wants to acclerate policy discussions by providing evidence about innovation trends, technology ownership and other background information in the green tech field. The report shows an increase of patent filing between 2006 and 2011 of 24 % regarding the four selected CCMTs. In fact, between these five years more patents in these sectors have been filed than in the last 30 years (see below). Also interesting is that China and the Republic of Korea have filed the most patents in the last years in relation to the four CCMTs. However in the area of solar photovoltaic the top 20 technology owners are all centered in Asia.   To see the whole report, follow the link: http://www.wipo.int/export/sites/www/policy/en/climate_change/pdf/ccmt_report.pdf
