The HRFM Cleantech Group has released the Second Quarter, 2010 results of the Clean Energy Patent Growth Index (CEPGI), and the Shine On Solar edition of the CEPGI. Both reports show increases in patent activity across clean energy sectors, with the exception of biofuel patents, which decreased slightly.

The CEPGI provides an indication of the trend of innovative activity in the Clean Energy sector from 2002 to the present. Results from the second quarter of 2010 reveal the CEPGI to have a value of 437 granted U.S. patents which is the highest quarterly value since the tracking of the CEPGI began, along with being up 58 (over 15 percent) from the first quarter and up almost 60 percent from a value of 274 in the second quarter of 2009.

The Shine On Solar edition analyzes the solar sector and illustrates where patents are being granted within the solar arena. This edition analyzes solar energy trends in general with an emphasis on solar patenting trends during 2009 and early 2010.
