ENGLEWOOD, Colo. - October 9, 2012 - Gevo, Inc. (NASDAQ: GEVO), announced today
that the United States Patent and Trademark Office (USPTO) has awarded the
company U.S. Patent No. 8,283,505, which protects Gevo's Integrated Fermentation
Technology(®) (GIFT(®)).

"This patented technology includes a proprietary separation unit that is
designed to elegantly enable cost-efficient separation of isobutanol from other
components of the fermentation broth," said Brett Lund, Executive Vice President
and General Counsel of Gevo.

The technology covered by the '505 Patent "provides Gevo and its partners with a
significant competitive advantage, as it protects the most cost-efficient
separation technology available. The GIFT(®) system permits the continuous
removal of isobutanol as it is formed in the fermentation broth. This increases
productivity of the genetically modified yeast cells because yeast does not
thrive in high concentrations   of isobutanol," said Lund.  The technology also
increases final isobutanol concentrations extracted from the fermentation broth,
he added.

The USPTO granted the '505 Patent in view of art cited against Gevo's earlier-
issued U.S. Patent No. 8,101,808 in a reexamination request filed by Butamax
Advanced Biofuels, LLC.  "This means that the USPTO has determined that the '505
Patent is novel and inventive over the publications referenced in reexamination
of the '808 Patent," Lund said.

"Given the thorough examination conducted by the USPTO, we believe the patent is
quite strong and capable of withstanding challenges by competitors who are
attempting to produce isobutanol with inferior technologies," said Lund.  "We
believe these competitors will have great difficulty in producing isobutanol at
competitive costs without licensing this technology from Gevo."
