According to the Clean Energy Patent Growth Index, renewable energy patent activity reached an all-time high in 2012, up 30% from 2011. The Clean Energy Patent Growth Index is published quarterly by the Cleantech Group at Heslin Rothenberg Farley & Mesiti P.C. and has been tracking trends in the clean energy sector since 2002.

Victor Cardona, co-chair of the Cleantech Group, stated, “We are pleased to announce the results for the Clean Energy Patent Growth Index, which reveal Clean Energy Patents jumped 30% to hit an all-time high in 2012, up over 700 patents relative to 2011. Toyota took the yearly Clean Energy Patent Crown from GE in 2012 while also leading the fuel cell and hybrid/electric vehicle sectors. U.S. patent holders hold more U.S. patents than any other individual country, but less than the combination of all the other countries. Also, solar and wind patents continued their rise, with solar patents for the lead sector in clean energy patents.”
