The United States Patent and Trademark Office granted 649 patents for clean energy-related technologies in the first quarter of the year, the Cleantech Group said.
The group compiles the quarterly Clean Energy Patent Growth Index to track the granting of patents for nine sectors – solar, wind, hybrid or electric vehicles, fuel cells, hydroelectric, tidal or wave, geothermal, biomass/biofuels and “other clean renewable energy.”
The idea is to present a picture of how investments into the development of clean energy technologies are doing. The granting of a patent is a good indicator that efforts placed into developing a technology has been successful and it has enough perceived value to justify the time and expense put into it.
In the first quarter, fuel cells got the most number of patents with 232, followed by solar (188) and wind (157). Hybrid/electric vehicle technologies were granted 62 patents, followed by biomass and biofuel with 36, tidal with 22 and hydroelectric with five.
Japanese motor giant Toyota had the most with 49 patents granted – mostly for fuel cells and hybrid and electric vehicles. American electronics group G.E. followed with 33 patents – mostly in wind – followed by Vestas, with 30 patents all in wind.
The United States topped the patents list, followed by Japan (150) and then Germany (51). The index further subdivided the U.S. by individual states, with California taking the crown with 70 clean energy patents followed by Michigan with 49, New York (47), New Jersey (16), Texas (15), Massachusetts (14), Connecticut (12), France (11) and Delaware (10). – EcoSeed Staff
