The Clean Energy Patent Growth Index (CEPGI) provides an indication of the trend of innovative activity in the Clean Energy sector since 2002 in the U.S., along with Leading Patent Owners and Leading Country and State information. Results from the second quarter of 2008 reveal the CEPGI to have a value of 217 granted U.S. patents which is down three from the first quarter of 2008 and down from a value of 228 in the second quarter of 2007.

The components breakdown of the CEPGI illustrated in the figure shows fuel cells dominating the other components in absolute numbers, but a downward trend for fuel cell patents begun in the fourth quarter of 2006 continued, falling by 10 relative to the first quarter. Granted wind and solar patents headed along opposite trajectories for the last two quarters with wind ascending (48) and solar (21) descending. Hybrid/electric vehicle patents (14) continued their downward trend begun in early 2007.

Tidal/wave energy granted patents continued an upward trend since the third quarter of 2007 with 10, up 1 relative to the first quarter....MORE
