The number of clean energy U.S. patents granted in a quarter has reached a new high in the second quarter of 2012, according to the Clean Energy Patent Growth Index. The second quarter's 786 patents topped the first quarter total of 694, making it the highest tally in any quarter since the firm of Heslin Rothenberg Farley & Mesiti P.C. began tracking clean energy patents in 2002.

The categories of patents monitored are: solar and wind energy; hybrid and electric vehicles (EV); fuel cells; hydroelectric, tidal, and wave power; geothermal energy; biomass and biofuels; and other renewable energy. The most patents (264) were granted for fuel cells, followed by solar (188) and wind (187). Among those that were granted patents, Toyota topped the list with 46, mainly in fuel cells and EVs, followed by GE with 43, consisting mostly of wind energy patents, and General Motors with 30 patents concentrated in fuel cells and vehicles.
