The CLEAN ENERGY PATENT GROWTH INDEX (CEPGI), published quarterly by the Cleantech Group at Heslin Rothenberg Farley & Mesiti P.C. provides an indication of the trend of innovative activity in the Clean Energy sector. Results from the first quarter of 2014 reveal the CEPGI to have a value of 690 granted U.S. patents which is 225 lower than the fourth quarter of 2013 (which was the highest quarterly total on record) and 48 lower than one year prior. GM was granted the highest number of Clean Energy patents for the first quarter, taking the quarterly crown back from Toyota, leader for the fourth quarter of 2013, after GM won the annual crown for 2013. Solar patents again led the other technology sectors in the first quarter for the fourth quarter in a row - topping Fuel Cell patents by about ninety patents with Fuel Cells having dropped over 100 from the previous quarter.
