US Leads-JAPAN Tops Others


ALBANY, NY—Heslin Rothenberg Farley & Mesiti P.C. is pleased to announce results for the third quarter of 2013 for the Clean Energy Patent Growth Index (CEPGI) by the firm’s Cleantech Group.

The CEPGI tracks the granting of patents in the Clean Energy sector and monitors important technological breakthroughs in this field. Victor Cardona, Co-chair of the firm’s Cleantech Group stated, “Solar patents led Fuel Cell patents for the second straight quarter as the upward trajectory of Solar continued to dominate the other sectors. Longtime leader Fuel Cells again lagged. GM and Toyota continued their quarterly seesawing with GM taking the quarterly Clean Energy patent Crown back from Toyota. The US led all countries in granted US clean energy patetns. Of countries and US states, Japan led California followed by Korea, Michigan, Germany, New York, and Taiwan- the only change being Korea and Michigan switching spots.”

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 third quarter of 2013 reveal the CEPGI to have a value of 757 granted U.S. patents, which are 8 lower than the previous quarter and 41 lower than one year prior. GM was granted the highest number of clean energy patents for the third quarter, taking the quarterly lead back from Toyota. Solar patents again led the other technology sectors Quarterly results are illustrated below:


Solar patents fell 21 (225) from the second quarter but again topped Fuel Cell patents (195) to put the nail in the coffin of the longtime leader which had been the leading technology sector in the CEPGI - back to 2002 - before being toppled by Solar patents in the second quarter. Solar patents were up 3 compared to a year prior. Fuel Cells still lead Wind patents (146) in the third quarter by 51 patents, after dropping 14 patents from the second quarter and 87 from a year prior. Wind dropped 5 relative to the second quarter and 24 compared to a year prior.

Hybrid-Electric Vehicle patents was a big winner in the third quarter - up 14 to 108 patents granted and up 27 compared to the same time period in 2012. Tidal patents dropped 7 to 15 relative to the second quarter and were up 4 compared to a year prior. Biofuel/Biomass patents had the biggest jump of the various technologies with 17 more patents than the previous quarter at 64 which is the most quarterly patents for this sector since tracking of the CEPGI began in 2002. Biofuel/Biomass patents were also up 25 versus the third quarter of 2012. Geothermal patents were down five compared to the second quarter and down one versus a year ago. Other Alternative Energy patents jumped seven to 16 and were up five over the year before.

Seesawing back and forth, GM had 40 clean energy patents and retook the quarterly clean energy patent crown from Toyota (327) which had taken the quarterly crown from GM the quarter before. Hyundai (31) also topped Toyota in the third quarter coming in second to GM. Fuel Cells (25) and Hybrid/Electric Vehicle patents (13) led the way for GM which also uncharacteristically had two patents in Solar technologies. Hyundai had 17 Fuel Cell and 14 HEV patents, along with a Solar patent. Toyota (27) also split its patents between Fuel Cells (20) and Hybrid/Electric Vehicle patents (8). Samsung tied Toyota in quarterly clean energy patents with the most Solar patents among the leaders at 6 and also had 18 Fuel Cell patents granted. Mitsubishi (25) and GE (21) were four clean energy patent apart and not surprisingly led the others in Wind patents with Mitsubishi edging out GE by a 19 to 16 margin. GE and Mitsubishi also both had HEV and Solar patents with Mitsubishi leading GE 3 to 1 in HEV patents while GE led its rival by the same ratio in Solar patents. Honda had 9 Fuel Cell, 6 Hybrid/Electric Vehicle, and 2 Biomass/Biofuel patents while Ford trailed Honda by one clean energy patent having 13 HEV and 3 Fuel Cell patents. Nissan and Kia tied with 12 clean energy patents with Kia having 6 each of Fuel Cell and HEV patents while Nissan had 8 and 4 of each respectively. It is interesting to note that if Kia's total was combined with that of Hyundai, given Japan led non-U.S. holders of U.S. Clean Energy patents and individual U.S. states, as depicted below in the geographic charts, and had 151 patents in clean energy, up four from the previous quarter and down 61 from the same period a year prior. Japan again took the quarterly geographical Clean Energy patent crown over runner up California (70), which was down 16 from the previous quarter and down 13 from the third quarter of 2012. Korea (69) took third place switching spots with fourth place Michigan (61). Korea jumped 18 patents compared to last quarter and was up 15 over a year ago. Michigan fell 11 versus the second quarter but was up 11 from the third quarter of 2012.

Germany (55) again topped New York (34) and Taiwan (31) in clean energy patents, but by a bigger (over 20) margin than last quarter. Germany regained its patent footing - up 16 from the second quarter - and lost one compared to the same time period a year before. New York fell one compared to the previous quarter but was down 29 versus a year ago. Taiwan also fell 4 versus the second quarter of this year and one compared to the third quarter of 2012. Massachusetts (18) switched spots with its cross-country rival Texas (16) and led Denmark (15), Spain (14), China (13), New Jersey (12), Illinois (12), Ohio (11), France (10) and Switzerland (10) in clean energy patents in the third quarter of 2013.
