With less capital flowing from investors to inventors, clean energy patents are still flourishing. According to a recent report from Heslin Rothenberg Farley and Mesiti, the index of Clean Energy Patent Growth (CEPGI) had its best quarter since its inception in Q2 2009 with 274 patents granted, up from 217 year over year. Fuel cells, solar and hybrid/electric were the most active categories of patents filed. Company wise, Honda led with 14 fuel cell patents and 3 hybrid/electric patents. GM was second place with a total of 15 patents granted. Geographically, Japan led with 75 patents, and California was second with 29. This CEPGI is a good indicator of innovation and development providing future opportunities for investors and funds.
