Monica A. Mark

Monica A. Mark is a Shareholder in the Intellectual Property Litigation team at Reinhart Boerner Van Deuren s.c., where her practice is primarily focused on patent litigation, alongside trademark, trade dress, and copyright matters. Her experience encompasses the full lifecycle of patent cases, from complaint filing through claim construction, summary judgment, and trial. Mark's case involvement, particularly with disputes such as Champion Power Equipment Inc. v. Generac Power Systems Inc., suggests a focus on mechanical and power equipment technologies, including multi-fuel generators and carbon monoxide detection systems.

Mark exhibits a strong preference for defending clients, with five of her six tracked appearances being on the defendant's side. Her firm's intellectual property practice highlights a role in "defending against unfair assertions by patent trolls". She is actively involved in appellate work, having briefed appeals in various state and federal courts and argued before the U.S. Court of Appeals for the Seventh and Fifth Circuits.

In addition to district court litigation, Mark possesses experience in patent-related administrative proceedings, including inter partes review (IPR). Notably, she represented Generac Power Systems Incorporated as a petitioner in an IPR against Champion Power Equipment Incorporated (IPR2025-01272), which was filed in July 2025 and terminated in January 2026. Her firm states that it was "one of the first practices in the country to initiate and handle inter partes review proceedings".

Mark earned her J.D., summa cum laude, from the University of Wisconsin Law School, where she was inducted into the Order of the Coif, and holds a B.A. from Yale University. She is admitted to practice in Wisconsin, and before the U.S. Courts of Appeals for the Federal, Fifth, Seventh, and Eleventh Circuits, as well as the U.S. District Courts for the Eastern and Western Districts of Wisconsin.
