Ethanol Boosting Systems, LLC

Ethanol Boosting Systems, LLC (EBS) is a company based in Cambridge, Massachusetts, known as the exclusive licensee of several patents owned by the Massachusetts Institute of Technology (MIT). While a 2011 article indicated their involvement in developing ethanol-injection fuel systems, current public information predominantly characterizes EBS by its patent assertion and licensing activities. No information on founding year, employee count, or revenue is publicly available.

EBS's core operations revolve around a patent portfolio licensed from MIT, which covers advanced fuel management systems for internal combustion engines. Specifically, these patents relate to methods for mitigating "engine knock" and improving efficiency in gasoline engines through the coordinated use of direct and port fuel injection, often involving ethanol as an anti-knock agent.

In terms of patent litigation, Ethanol Boosting Systems, LLC exhibits the posture of an entity asserting licensed intellectual property. The company has been a plaintiff in two tracked cases and a defendant in one, primarily in disputes concerning its automotive-related patents. The defendant case occurred at the Patent Trial and Appeal Board (PTAB), where the validity of its licensed patents was challenged. These cases have spanned the District of Delaware and the U.S. Court of Appeals for the Federal Circuit, both common venues for patent disputes.

All tracked litigation involves Ford Motor Company, with EBS and MIT jointly suing Ford for patent infringement in the District of Delaware. In response, Ford challenged the validity of several MIT-owned patents (U.S. Patent Nos. 10,619,580, 10,781,760, and 9,708,965), exclusively licensed to EBS, at the PTAB. As of December 2025, the Federal Circuit affirmed PTAB decisions finding multiple claims of these patents unpatentable. This outcome represents a significant development in the company's efforts to assert its portfolio.
