Clean Energy US Patents in 2009, Increased by 20%

The fourth quarter of 2009 for the Clean Energy Patent Growth Index (CEPGI) was issued by Cleantech Group of Heslin Rothenberg Farley & Mesiti P.C.

1) The number of patents granted in the clean energy sector has rapidly increased
2) The number of the granted patents in the automobile sub-sector is much larger than those in the remaining sub-sectors. The figure is outstanding.
3) Honda is still strong in the clean energy sector.
4) GE, one of major companies in the U.S., is actively developing the clean energy technologies, including particularly the wind power technology.
****************

Results through the fourth quarter of 2009 reveal the CEPGI for 2009 to be at its highest level in the eight year period of its tracking at 1125 granted patents, up over 20 percent (about 200 patents).

Patents in fuel cells and hybrid/electric vehicles were each up over twenty percent over 2008 with solar patents up sixty percent and biomass/biofuel energy patents up two hundred sixty percent. Fuel Cells, wind, and biomass/biofuel energy patents were also at all time highs in 2009. In contrast, hydroelectric and tidal patents decreased in 2009 while geothermal patents were up only one patent over the year prior.

Honda again claimed the Clean Energy Patent crown in 2009 by edging General Motors out by four patents. Honda leads overall since 2002 and automobile companies occupy 5 of the top ten patent leader spots since 2002.

GE made the top ten in 2009 continuing its strong showing in clean energy patents having over twice the patents of its nearest wind patent competitor, Aloys Wobben, the owner of Enercon GmbH of Germany.
