Gevo Dismisses Butamax Patent Infringement Lawsuit; Scope Mirrors ‘188 Patent Previously Rejected by USPTO
May 15 2012 - 8:37AM
Business Wire
Gevo, Inc. (NASDAQ: GEVO), a leading renewable chemicals and
next-generation biofuels company, commented on the lawsuit filed
today by Butamax™ Advanced Biofuels, LLC (Butamax) alleging
infringement of U.S. Patent No. 8,178,328 (‘328 Patent).
“The claims in the ‘328 Patent are virtually identical to the
claims in Butamax’s earlier-issued 7,851,188 Patent (‘188
Patent) which were recently rejected and declared unpatentable by
the U.S. Patent and Trademark Office during reexamination,” said
Brett Lund, Gevo’s Executive Vice President and General Counsel.
“The ‘328 Patent issued from a child application of the ‘188 Patent
and purports to cover engineered isobutanol-producing
microorganisms.”
“Like Butamax’s ‘188 Patent, the technology described in the
‘328 Patent was invented by others and repeatedly described in
journal publications dating back to the 1960s,” continued Lund. “We
will request reexamination of the ‘328 Patent using similar
arguments and are extremely confident that the outcome will be the
same.”
