In many cases, ITC investigations are not stand-alone proceedings—Section 337 complaints are often accompanied by complaints filed in federal district court. These parallel complaints often are based upon the very same unfair acts underlying the alleged Section 337 violation, such as patent infringement, trademark infringement, or trade secret misappropriation. In this episode of Talkin’ Trade, Ropes & Gray IP litigators Matt Rizzolo, Matt Shapiro, Brendan McLaughlin, and Meredith Foor explore the issues created by such parallel complaints, including the potential for litigation on two fronts and the possible preclusive effect—or lack thereof—of Commission determinations.
