Patents Q3 Energy ManageThe number of solar patents recorded a new high of 335, up 29 over the previous record set in the second quarter of 2013, and 110 over the third quarter of 2013, according to the Q3 2014 Clean Energy Patent Growth Index (CEPGI). This is the sixth straight quarter that solar patents have topped the patent index.

Fuel cells patents totaled 264, a jump of 32 patents over Q2 and 69 over the year before, but trailed solar patents by more than 70 patents in Q3 2014.

The top three automakers to be issued fuel cell patents in Q3 2014 were Toyota with 38, GM with 24 and Honda with 18. Toyota unseated GM for the highest number of clean energy patents in 2012.

Wind patents rose to 170 and were up 24 compared to the same period in 2013. Siemens secured the highest number of wind patents at 25.

Biofuel/biomass patents were the only technology sector to take a hit in the third quarter, dropping nine compared to the second quarter while being down two relative to the third quarter of 2013.

Nine geothermal patents were issued, up four compared to Q2 2014 and up seven compared to Q2 2013.

The CEPGI is published quarterly by the Cleantech Group at Heslin Rothenberg Farley & Mesiti.
