CAS Chemistry Research Report: 40 Years of Biofuel Research Reveal China Now Atop U.S. in Patenting and Commercialization of Bioethanol

Columbus, Ohio (June 24, 2010) - Chemical Abstracts Service (CAS), the world's authority for chemical information, reports that in 2009, China surpassed all other countries in the production of bioethanol patents, emerging as the global leader in the commercialization of bioethanol research.

In the CAS Chemistry Research Report: China Takes Lead in the Commercialization of Bioethanol, CAS examines 40 years of scientific research into biofuel development. Their key finding is that although U.S. researchers continue to publish more scientific research about bioethanol than other countries, China now produces more bioethanol-related patents than anyone. Other important findings include:

  • The U.S. published 105 journal articles related to first- and second-generation bioethanol research in 2009, more than any other country.
  • However, in the same year, the State Intellectual Property Office (SIPO) of the People's Republic of China issued the most bioethanol-related patent documents (156).
  • From 2000 to 2009, global research literature on second-generation bioethanol (derived from non-food sources, such as wheat stalks) grew 586 percent, including patenting activity that skyrocketed 2,341 percent.
  • Research into second-generation bioethanol significantly outpaced examination of first-generation (derived from edible feedstocks) and third-generation (derived from algae) bioethanol.
  • U.S. researchers are foremost within the newest category of bioethanol research: third-generation, or algae-based, bioethanol.

"The global research focus on second-generation bioethanol shows a rising interest in a category of fuels widely considered more sustainable, affordable, and environmentally friendly than bioethanol available today," said Christine McCue, vice president of marketing at CAS.


About CAS

Chemical Abstracts Service (CAS), a division of the American Chemical Society, is the world's authority for chemical information. CAS is the only organization in the world whose objective is to find, collect and organize all publicly disclosed substance information. A team of scientists worldwide curates and controls the quality of our databases, which are recognized as the most comprehensive and authoritative by chemical and pharmaceutical companies, universities, government organizations and patent offices around the world. By combining these databases with advanced search and analysis technologies (SciFinder® and STN®), CAS delivers the most current, complete, secure and interlinked digital information environment for scientific discovery.


About CAS Chemistry Research Reports

The CAS Chemistry Research Report series examines journal and patent publication records to identify global trends in scientific research and its commercialization. The reports are developed by CAS scientists and other researchers, who analyze decades of data represented in CAS databases, the largest and most authoritative databases of scientific information.
