The US Patent and Trademark Office granted a record , clean energy technology patents in , a percent increase over the previous year and led by Toyota, according to an index published by Cleantech Group.
The Clean Energy Patent Growth Index, which provides a measure of inventive activity and evidence of the effectiveness of research and development investments, tracks US patents for solar, wind, hybrid and electric vehicles, fuel cells, hydroelectric, tidal and wave, geothermal, biomass and biofuels and other clean renewable energy.
Toyota had patents in , beating out last year’s top CG Leads patent holder GE to take the No. spot on the CEPGI. GE added patents in . Toyota received the highest number of clean energy patents in every quarter of .
GM took the third spot on the CEPGI with patents, followed by Samsung with , Honda with , Mitsubishi with , Vestas with , Siemens with , Hyundai with and Ford with patents in . Nissan fell out of the top on the index in .
Honda continues to lead in overall clean energy patents granted since , but is losing ground every year to other companies, Cleantech Group said. GM is close behind Honda in terms of patents granted since , followed by Toyota and GE. Five of the top overall clean energy patents holders are auto manufacturers with the remaining five including an assortment of wind, solar and fuel cell makers.
The fuel cell sector saw patents rise percent to , in , leading all other sectors for the total number of patents. Solar, which trailed fuel cells with patents, experienced a percent increase from , according to CEPGI. Wind, which took the No. spot in , saw its number of patents jump percent from .
Meanwhile, biomass and biofuel patents led the lower tier with patents, reflecting a percent increase from , followed by tidal energy, which recorded patents.
