David M. Maiorana: Professional Summary

David M. Maiorana is a patent trial lawyer and a partner in the Cleveland office of Jones Day, where his practice focuses on complex patent litigation in federal district courts and the International Trade Commission (ITC). His background as a former patent examiner for the U.S. Patent and Trademark Office (USPTO) informs his work across a wide range of technologies, including consumer products, medical devices, and chemicals. His representative matters show a focus on areas such as e-cigarettes and vaporizers, teeth whitening products, pharmaceuticals, and flash memory.

While the provided data shows a single recent appearance as lead counsel for plaintiff Reynolds American Inc., Maiorana's broader practice description indicates he represents both plaintiffs and defendants in high-stakes patent disputes. His work for major operating companies is extensive, with long-standing representations of clients like The Procter & Gamble Company, AbbVie, Goodyear, and R.J. Reynolds. In a notable result, he served as first-chair trial counsel for R.J. Reynolds in an ITC investigation involving e-cigarettes that resulted in exclusion and cease-and-desist orders, which were later affirmed by the Federal Circuit.

Maiorana has significant experience in post-grant proceedings before the Patent Trial and Appeal Board (PTAB). He frequently serves as lead counsel in inter partes review (IPR) proceedings for both patent owners and petitioners and has co-authored numerous articles on PTAB practice and developments.

He holds a B.S. in Chemical Engineering from the University of Virginia and a J.D. from American University.
