The Clean Energy Patent Growth Index (CEPGI) again reached a record high in the third quarter of 2010. According to HRFM’s Cleantech Group, the CEPGI was up 12 percent over the first quarter and up 45 percent over a year prior. Further, all Clean Energy sectors were up this quarter except for one which matched the second quarter result.



Fuel cells were up 5 granted patents relative to the second quarter at 253 and up 96 relative to a year before while continuing to dominate the other components of the CEPGI in absolute numbers. Granted solar patents (88) continued to top the other components, and its closest competitor, wind (71) by 17. Solar patents were up 12 compared to the second quarter of 2010 and up 55 relative the third quarter of 2009. Wind patents were up 16 relative to the second quarter and up 36 compared to a year prior. Hybrid/electric vehicle patents (46) were up 13 relative to the second quarter and up 24 relative to the third quarter of 2009. Biofuel patents (16) were up 4 from the second quarter and up 5 over a year prior. Hydroelectric patents had the highest total quarterly ever at 12, far exceeding any previous quarter for the year, and with 12 different entities receiving these patents.



General Motors took the quarterly Clean Energy Patent crown from perennial holder Honda which fell to an uncharacteristic 5th place this quarter. GM’s patents were primarily in Fuel Cells at 30 with an assist from Hybrid/Electric vehicle patents at 9. Samsung followed with Fuel Cell (21), hybrid/electric vehicle (1) and solar (3) patents. GE had a strong showing in third place primarily buoyed by its wind patents (19) assisted by its fuel cell (3) patents and one hybrid/electric vehicle patent. Auto companies followed and took fourth to sixth place. Toyota had 14 fuel cell and 6 hybrid/electric vehicle patents and Honda had slightly more fuel cell (17) and less hybrid/electric vehicle patents (2). Nissan had 12 patents in hybrid/electric vehicles (9) and fuel cells (3). Panasonic was next with 10 fuel cell patents. Third generation solar manufacturer, Konarka, and Aloys Wobben, owner of wind company, Enercon GmbH, tied for 8th place and each had 7 patents in its area of expertise. Canon (4 fuel cell, 2 solar), and Sanyo (2 fuel cell, 4 solar) tied for 9th place. Ford rounded out the field of leaders with 6 hybrid/electric vehicle patents.
