Business Wire
Gevo, Inc. (NASDAQ: GEVO), a renewable chemicals and advanced
biofuels company, today received a landmark patent from the United
States Patent and Trademark Office (“USPTO”) on its GIFT®
separation unit, a central element in the Company’s unique
fermentation technology for the production of isobutanol.
Gevo was awarded U.S. Patent No. 8,101,808, “Recovery of Higher
Alcohols From Dilute Aqueous Solutions.” This patent addresses the
separation technology used to produce propanols, butanols,
pentanols, and hexanols. The claims also address how ethanol plants
can be retrofitted to produce higher alcohols.
“This is one of several foundational Gevo patents. The
technology described in this patent enables the separation of
alcohols from fermentation broth using an elegantly simple design.
It solves the long-standing problem for the practical production of
higher alcohols, specifically how to separate these alcohol
products from fermentation broth and achieve economic
concentrations. This is the technology, along with our proprietary
yeast, being implemented at our Luverne, Minnesota plant,” said
Brett Lund, EVP & General Counsel of Gevo. “With the broad
coverage of this patent and its 156 claims, it is a significant
patent. This technology combined with other elements of our patent
estate that cover our biocatalyst, metabolic engineering and
enzymes, cause us to believe that we have the intellectual property
foundation to provide us and our partners a significant competitive
advantage.”
Gevo also filed a lawsuit against Butamax™ Advanced Biofuels LLC
(“Butamax”) and its affiliate E.I. du Pont de Nemors and Company
(“DuPont”) charging that Butamax and DuPont infringe the newly
issued patent.
Gevo’s proprietary integrated recovery process and related
services, or the GIFT® system, provides enhanced fermentation
performance as well as low-cost, energy-efficient isobutanol
recovery. The GIFT® system permits the continuous removal of
isobutanol as it is formed, increasing productivity and final
product concentration.
