Koren is a recognized thought leader on competition issues who has testified before Congress on domestic and international issues in antitrust policy. She has more than eighteen years of experience in government, private practice, and as in-house counsel, including representing defendants and plaintiffs in high-stakes litigations and representing companies in domestic and foreign investigations. While at the Federal Trade Commission (FTC), Koren served as an Attorney Advisor to Commissioner Joshua Wright and Counsel for Intellectual Property & International Antitrust.  The combination of Koren's experience representing defendants—along with her experience at the FTC and as a former plaintiffs class action attorney—gives her insights into the thinking on both sides of cases, including complex multi-district litigations, allowing her to develop both effective offensive and defensive strategies. On top of this, her​ in-house experience as the Director of Antitrust Litigation & Policy at a major technology company gives her a first-hand understanding of how companies work and unique insight into the needs of clients. Koren also has a deep understanding of economics, as evidenced by the fact that she has trained over 500 foreign judges and enforcers on a variety of economic topics.   Koren’s scholarship has been cited by courts and the Department of Justice. She has authored over sixty articles, including on vertical mergers and restraints, acquisitions of potential competitors, consummated mergers, multisided platforms, the intersection of antitrust and intellectual property, incremental innovations or “product hopping,” optimal penalties, extraterritoriality, methodologies for calculating patent infringement damages, and international due process and convergence. She has spoken at over 200 domestic and international events.
