William Daniel O'Connell

William Daniel O'Connell is a patent litigator at Susman Godfrey, known for his work on both the plaintiff and defendant sides in complex intellectual property disputes. His practice areas, as evidenced by his tracked cases, appear to focus on mechanical engineering and automotive technology, specifically relating to engine and fuel management systems designed to enhance efficiency and mitigate issues like engine knock.

O'Connell has represented clients in significant matters, including Ethanol Boosting Systems, LLC et al. v. Ford Motor Company, where he served as Counsel for the plaintiff. This case involved patents owned by the Massachusetts Institute of Technology (MIT) concerning optimized fuel management systems for direct injection ethanol enhancement of gasoline engines. Related inter partes review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB) ultimately found the challenged claims of the MIT-owned patents unpatentable. These PTAB decisions were subsequently affirmed by the U.S. Court of Appeals for the Federal Circuit in December 2025. Concurrently, O'Connell also acted as of counsel for Ford Motor Company in Ford Motor Company v. Massachusetts Institute of Technology et al., demonstrating his experience representing defendants in related district court infringement actions.

While the cases in which O'Connell has appeared involve extensive PTAB and Federal Circuit activity, detailed information regarding his direct and regular appearance in IPR or PGR proceedings is not readily available in public records. Similarly, specific details of his professional background, including his bar admissions and educational institutions, could not be reliably sourced from public information distinct from other attorneys sharing similar names. His work at Susman Godfrey highlights his engagement in high-stakes patent litigation involving intricate mechanical and automotive technologies.
