Matthew J. Hertko

Matthew J. Hertko is an intellectual property partner at Jones Day in Chicago who focuses on high-stakes patent litigation. His practice has a particular emphasis on representing innovator pharmaceutical companies in Hatch-Waxman litigation, though he has also litigated cases across a wide spectrum of other technologies, including consumer electronics, semiconductors, integrated circuits, and automotive systems. He has experience in various forums, including numerous federal district courts, the International Trade Commission (ITC), and in post-grant proceedings before the Patent Trial and Appeal Board (PTAB).

Consistent with the provided case list showing him exclusively as defense counsel, Hertko primarily defends operating companies in patent disputes. His notable representations include defending Tineco Intelligent Technology against Bissell Inc. in an ITC investigation related to wet-dry surface cleaning devices. In that matter, the ITC ultimately determined that Tineco's redesigned products did not infringe, a finding that was affirmed by the Court of Appeals for the Federal Circuit in May 2026. He has also defended clients such as Qualcomm, Seiko Epson, and Cohesity in significant patent infringement suits.

Hertko is a partner at Jones Day, which he joined as of counsel in 2014 from Kirkland & Ellis. His practice includes representing clients in jury trials and appeals, and he has successfully represented clients like Celgene in defeating the institution of inter partes review (IPR) petitions at the PTAB.

Hertko earned his J.D. from the University of Illinois College of Law, where he was an articles editor for the law review, and a B.S. in Civil Engineering from Northwestern University. He is admitted to practice in Illinois.
