Patent trends identify 4 key climate change mitigation technologies

The top line in a recent WIPO report about IP trends in the renewable energy landscape reads that “more patents have been filed in the last 5 years than in the previous 30 years across key CCMTs* examined by the report (biofuels, solar thermal, solar photovoltaics (PV) and wind energy). While the average global rate of patent filing grew by 6 per cent between 2006 and 2011, these CCMTs have experienced a combined growth rate of 24 per cent over the same period – four times the rate of growth.”

“Also notable is the shift in innovation from West to East. China and the Republic of Korea have filed the most patents in recent years across all four technology areas, while in solar PV, the top 20 technology owners are all based in Asia.
