CleanTech Sues Aemetis for Infringing Patented Corn Oil Extraction Method

Indianapolis, Indiana — Patent lawyers for GS CleanTech Corp. of Alpharetta, Georgia (“CleanTech”) filed a patent infringement suit in the United States District Court for the Eastern District of California — Fresno Division alleging that Aemetis, Inc. and Aemetis Advanced Fuels Keyes, Inc., (collectively, “Aemetis”), both of Cupertino, California, infringed CleanTech’s METHOD OF PROCESSING ETHANOL BYPRODUCTS AND RELATED SUBSYSTEMS, Patent No. 7,601,858, (the “‘858 patent”) which has been issued by the U.S. Patent Office.  The case was transferred to the Southern District of Indiana as part of Multidistrict Litigation No. 2181.

This Multidistrict Litigation (“MDL”) began with an assertion of patent infringement by CleanTech of the ‘858 patent, which was issued on October 13, 2009.  CleanTech sued numerous Defendants alleging infringement of that patent shortly after its issuance.   The Defendants accused of patent infringement in prior litigation include: Big River Resources Galva, LLC; Big River Resources West Burlington, LLC; Cardinal Ethanol, LLC; ICM, Inc.; LincolnLand Agri-Energy, LLC; David J. Vander Griend; Iroquois Bio-Energy Co., LLC; Al-Corn Clean Fuel; Blue Flint Ethanol, LLC; ACE Ethanol, LLC; Lincolnway Energy, LLC; United Wisconsin Grain Producers, LLC; Bushmills Ethanol, Inc.; Chippewa Valley Ethanol Co.; Heartland Corn Products and Adkins Energy, LLC.

Since September 29, 2011, when the court overseeing the MDL issued its order on claim construction with respect to the disputed claims of the ‘858 patent, patentees, GS CleanTech Corp., and its parent GreenShift Corp., have asserted three additional patents in the ‘858 patent family against the allegedly infringing Defendants, U.S. Patent Nos., 8,008,516 (the “‘516 patent”), 8,008,517 (the “‘517 patent”) and 8,283,484 (the “‘484 patent”) (the ‘858, ‘516, ‘517 and ‘484 patents are, collectively, the “‘858 patent family”).

In this current lawsuit, initiated in Eastern District of California, subsidiary GS CleanTech Corp. is the sole Plaintiff.  Patent attorneys for CleanTech assert only one count in the complaint: infringement of the ‘858 patent.  CleanTech asks the court for preliminary and permanent injunctions prohibiting further infringement of the ‘858 patent; an award of damages adequate to compensate CleanTech for the infringement that has occurred, but in no event less than a reasonable royalty for the use made of the inventions of the ‘858 patent as provided in 35 U.S.C. § 284, together with prejudgment interest from the date the infringement began; and an award to CleanTech of all remedies available under 35 U.S.C. §§ 284 and 285.

Practice Tip: The United States Judicial Panel on Multidistrict Litigation, also known as the “MDL Panel” or, simply the “Panel,” consists of seven sitting federal judges, who are appointed to serve on the Panel by the Chief Justice of the United States. The job of the Panel is to (1) determine whether civil actions pending in different federal districts involve one or more common questions of fact such that the actions should be transferred to one federal district for coordinated or consolidated pretrial proceedings; and (2) select the judge or judges and court assigned to conduct such proceedings.

This case has been assigned to Judge Larry J. McKinney and Magistrate Judge Debra McVicker Lynch in the Southern District of Indiana and assigned Case No. 1:13-cv-08014-LJM-DML.
