David M. Marcus

Profile

David M. Marcus is Of Counsel in McNees’ Intellectual Property Group, where he advises clients on protecting and managing their intellectual property with respect to patents, design patents, and litigation matters. He prepares and prosecutes U.S. and foreign patent applications across a variety of technologies, provides freedom-to-operate, non-infringement, and invalidity opinions, and assists clients in asserting or defending patent and trademark claims in federal court.

In particular, he applies his scientific background in chemistry, including catalytic, inorganic, organic, and analytical chemistry, to support clients ranging from Fortune 50 corporations to first-time inventors.

In addition to patent work, he has handled criminal and white-collar defense matters and supported clients in complex civil disputes.

Before joining McNees, David conducted graduate and post-doctoral research in methanol-to-olefin zeolite catalysis at the University of Southern California and ExxonMobil Chemical. He has published extensively in peer-reviewed journals, including Angewandte Chemie, Journal of the American Chemical Society, and Journal of Catalysis.

David is admitted to practice in Ohio, California, and before the U.S. Patent and Trademark Office, as well as in the U.S. District Courts for the Northern and Southern Districts of Ohio, and the U.S. Court of Appeals for the Sixth Circuit.

Outside of work, David balances family life with two young children and no longer remembers what the concept of “free time” refers to. When not building Legos or reading books with his kids, he enjoys cooking, reading, board games, Aikido (second-degree black belt), theater, and travel.
