Karen Dunn, a Fellow of the American College of Trial Lawyers, is widely recognized as one of the country’s premier trial lawyers. Among other recognitions, Karen has been named a “Litigator of the Year” by The American Lawyer for her role in “high-stakes, high-profile, and hard-fought” cases. Karen has also been recognized as a “Star Individual” for Trials by Chambers and Partners, which reports that Karen’s clients call her “a go-to lawyer for your toughest, most-challenging problems.”
Karen is also Chambers and Partners-ranked in Band 1 for Crisis and Risk Management, advising companies, public figures, and boards of directors as they navigate reputation-threatening investigations, government inquiries, and media scrutiny — often all at the same time. Profiled in the New York Times as a lawyer unafraid of telling hard truths, Karen has also led debate preparations for candidates for President, Vice President, and Senate — experience that makes her uniquely qualified to prepare C-suite executives in make-or-break moments.
Karen has successfully led some of the largest and most important trials of the past decade, including Waymo LLC v. Uber Technologies, Inc., the hotly contested trade secrets “battle royale,” which settled favorably for Uber shortly after Karen’s examination at trial of former CEO Travis Kalanick; Malden Transportation, Inc. v. Uber Technologies, Inc., where she delivered a complete defense victory in a $750 million dispute after being brought in to lead the trial team just six weeks before trial; Epic Games Inc. v. Apple Inc., the high-stakes challenge to the App Store by the makers of Fortnite, which ended in victory for Apple following a three-week trial; Apple Inc. v. Qualcomm Incorporated, where she secured a $4 billion summary judgment win for Apple in the lead-up to trial; the Apple iPod iTunes Antitrust Litigation, a billion-dollar class action, where the team delivered a complete defense jury verdict; Monster, LLC v. Beats Electronics, LLC, winning summary judgment for Beats on the eve of trial; Oracle USA, Inc. v. Rimini Street, Inc., where she won trial victories in both 2015 and 2022 including a permanent injunction against Rimini over its copying of Oracle software; and ARM Ltd. v. Qualcomm Inc., where she secured a jury verdict for Qualcomm in a case worth tens of billions of dollars with far-reaching consequences for innovation and competition.
