Major Ruling In Litigation Over Greenshift’s Corn Oil Extraction Patents
GreenShift Corporation (OTCQB: GERS) today announced the issuance of a significant ruling in its ongoing prosecution of ethanol producers and other entities for infringement of GreenShift’s patented corn oil extraction processes, including U.S. Patent Nos. 7,601,858, 8,008,516, 8,008,517, and 8,283,484.
GreenShift believes that the ruling dramatically strengthens its case for infringement against any person or entity recovering or facilitating the recovery of corn oil from the concentrated thin stillage by-product of ethanol producers.
All of the following defendants in GreenShift’s current litigation argued that GreenShift’s patents are limited to the recovery of at least 95% of the oil present in the concentrated thin stillage feed stream, and that they are consequently not infringing on GreenShift’s patents because they are recovering less than 95% of the oil present in their concentrated thin stillage feed streams: (1) Ace Ethanol; (2) Al-Corn Clean Fuel; (3) Blue Flint Ethanol; (4) Bushmills Ethanol; (5) Chippewa Valley Ethanol; (6) Heartland Corn Products; (7) Lincolnway Energy; (8) United Wisconsin Grain Producers; (9) Iroquois Bio-Energy Company; (10) Cardinal Ethanol; (11) ICM; (12) Big River Resources West Burlington; (13) Adkins Energy; (14) Big River Resources Galva; (15) Lincolnland Agri-Energy and (16) David Vander Griend.
The Court disagreed with the defendants’ arguments, and issued a Supplemental Claim Construction Order clarifying that the patents do not require recovery of any particular percentage of oil present in the syrup feed stream.Significantly, the Court ruled that most of GreenShift’s patent claims cover mechanical processing to recover a product that is largely or mostly oil, and that they are not limited by the amount of oil that is not recovered from the concentrated thin stillage stream. “We are very pleased with the Court’s ruling,” said David Winsness, GreenShift’s Chief Technology Officer and co-inventor of its patented corn oil extraction technologies. “We have looked at the so-called advanced oil, oil plus, COSS and such other attempts to work around our patents. We are highly confident, and even more so with this latest ruling, that all such attempts plainly infringe our patents.”
