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 second quarter of 2014 reveal the CEPGI to have a value of 940 granted U.S. patents, which is the highest total for any quarter on record. This is also 250 higher than the first quarter of this year and 25 more than the fourth quarter of 2013 (which was the previous highest quarterly total on record), along with being almost 200 more than one year prior. The clean energy patent crown has become a hot potato as Toyota took the top spot back from GM, the winner from the first quarter after taking the crown from its Japanese competitor. Solar patents were at a new high and again led the other technology sectors in the second quarter for the fifth quarter in a row - leading runner up Fuel Cells by over 70 patents with Fuel Cells having jumped 60 patents compared to the previous quarter.
