Appeals Court Issues Opinion Sending Case Back to District Court

Court Orders District Court Proceedings Considering Revised Claim

ENGLEWOOD, Colo., Feb. 18, 2014 (GLOBE NEWSWIRE) -- Gevo, Inc. (Nasdaq:GEVO),
the world's only commercial producer of renewable isobutanol, announced today
that the U.S. Court of Appeals for the Federal Circuit (Appeals Court) issued
a decision in a patent case involving Butamax's Patent Nos. 7,851,188 ('188
Patent) and 7,993,889 ('889 Patent). The appeals court offered a new
interpretation of a disputed claim term, vacated the district court's prior
rulings, and ordered the court to reconsider issues related to infringement
and invalidity.

On remand, two issues remain to be determined: 1) whether the patents are
valid; and 2) whether Gevo infringes them under the new claim interpretation.
The claims of the two Butamax patents at issue are currently under
reexamination at the United States Patent and Trademark Office (USPTO), which
has declared them unpatentable. Gevo believes that it does not infringe any
valid claims, and at this time maintains freedom to produce and sell
isobutanol worldwide and into all markets.
