Greenshift files patent infringement

By | April 15, 2010
Greenshift Clean Tech Corp. received a third patent for its corn oil extraction technology. The patent came at the same time Greenshift issued an infringement complaint against Cardinal Ethanol LLC and Big River LLC, facilities using corn oil technology. GS, which claims it innovated and created the technology, believes the company deserves the full measure and advantage of creating the technology first. ICM Inc. manufactured and installed the Cardinal Ethanol and Big River facilities with the corn oil technology and will now defend both facilities after filing litigation against GS. "ICM believes that GS Clean Tech's alleged patent claims will be proved to be invalid," said Chris Mitchell, vice president of marketing for ICM.
