"On December 23, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision in Ethanol Boosting Systems, LLC v. Ford Motor Company, affirming the Patent Trial and Appeal Board's (PTAB) invalidation of three patents owned by the Massachusetts Institute of Technology (MIT) and licensed to Ethanol Boosting Systems (EBS). The opinion was authored by Judge Chen and joined by Judges Clevenger and Hughes."
"The patented system contains two injection mechanisms, direct injection and port injection. In direct injection, a valve sprays fuel directly into the cylinder, whereas in port injection, a valve sprays fuel into a passageway adjacent to the cylinder, where it mixes with air before entering the cylinder. At lower torque values, only the port injector operates, but at higher torque values, both injection mechanisms are utilized. As torque increases, the direct injector supplies an increasingly greater percentage of the fuel."
The CAFC affirmed the PTAB's invalidation of U.S. Patents 10,619,580; 10,781,760; and 9,708,965, owned by MIT and licensed to Ethanol Boosting Systems. The patents describe a fuel management system that combats engine knock by injecting an anti-knock agent directly into the engine cylinder to produce evaporative cooling. The system employs both direct and port injection, with port injection used at lower torque and both injectors used at higher torque, the direct injector contributing a larger fuel percentage as torque increases. The dispute began when EBS sued Ford and Ford sought inter partes review challenging the patents.
