Josh Rosenkranz is head of the firm’s Supreme Court & Appellate Litigation practice.
A former law clerk to U.S. Supreme Court Justice William J. Brennan Jr. and then-Judge Antonin Scalia on the D.C. Circuit, Josh has personally argued more than 200 appeals in state and federal appellate courts across the nation, including 20 before the U.S. Supreme Court.
Josh is the only lawyer ever named American Lawyer's “Litigator of the Year” twice. In 2012, the magazine dubbed him “the Defibrillator” based on his streak of appellate wins for companies that “appeared to be at death’s door,” and in 2017 it declared, he “still deserves the moniker we once gave him.”
Chambers USA has reported, “He wins accolades for his ‘brilliant analysis and judgment.’ Clients appreciate how he ‘rethinks every case from the ground up,’ and add: ‘He can take the most complicated legal or technological issue and present it in a way that seems like common sense.’” Another edition of Chambers USA added: “‘His briefs are quite simply beautiful,’” and “clients describe his courtroom presence as ‘both commanding and accessible at the same time.’ He has the ‘perfect combination of persuasiveness, intelligence, wit, and deference.’”
Josh's practice covers a wide range of subjects, including securities, intellectual property, antitrust, federal preemption, insurance law, corporate governance, criminal law and constitutional litigation. Among his recent clients are Credit Suisse, DIRECTV, DISH Network, Facebook, Genentech, Gilead, JPMorgan Chase, Kleiner Perkins, LinkedIn, Microsoft, Morgan Stanley, Oracle, and Royal Bank of Scotland.
Clients turn to Josh to win the highest stakes appeals, including appeals in cases that threaten the very survival of a business. He represented Microsoft in an international cause célèbre in the U.S. Supreme Court challenging the U.S. Government’s claim that it can serve warrants for emails stored overseas. He represented DISH Network in one of the most high-profile patent appeals in the country, successfully overturning an injunction that threatened the company's life. He represented Facebook in the high-profile battle waged by the founder's Harvard classmates, the Winklevoss twins, who laid claim to the idea for Facebook, winning a ruling from the Ninth Circuit to end the lawsuit.
In 2005, he successfully represented Merck KGaA in a Supreme Court case that the National Law Journal described as “the most significant patent infringement case to confront the biotech and pharmaceutical industries in a generation.” He represented 36 law schools in a high-profile Supreme Court case against the Department of Defense. He also won a landmark victory in a Supreme Court case that rescued the estimated $60 billion U.S. market of copyrighted goods manufactured abroad.
Josh was the founding president and CEO of the Brennan Center for Justice at New York University School of Law, one of the country’s foremost public interest firms. Over the course of eight years, he was the Brennan Center’s chief strategist on litigation and public policy advocacy. Under his direction, the center represented parties in connection with more than 50 cases (including three at the U.S. Supreme Court). Before creating the Brennan Center, Josh founded the Office of the Appellate Defender, a public defender office specializing in criminal appeals.
Josh has published numerous books, monographs, chapters and scholarly articles. He has also authored 18 op-eds or articles in major newspapers and magazines, including The New York Times, The Washington Post, The Los Angeles Time, The Chicago Tribune, The Washington Monthly, The Boston Review, The National Law Journal, and The American Prospect.
