E. Joshua Rosenkranz Partner

New York

Josh has been named American Lawyer's “Litigator of the Year” twice, in addition to being a finalist for 2022. 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.”

In 2014, The Financial Times named Josh one of the 10 most innovative lawyers in the North American legal sector for his work “demystify[ing] the technical issues” and securing a victory in the blockbuster Federal Circuit appeal, Oracle v. Google. 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 intellectual property, financial services, securities, privacy, antitrust, federal preemption, insurance law, corporate governance, criminal law, and constitutional litigation. Among his recent clients are Cisco, Credit Suisse, Cox Communications, DISH Network, Genentech, Gilead, Johnson & Johnson, JPMorgan Chase, Microsoft, Mozilla, Oracle, Sonos, 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. For example:

• 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 has been lead counsel in multiple cases either defending or challenging verdicts over $1 billion.
• 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.
• He won a landmark victory in a Supreme Court case that rescued the estimated $60 billion U.S. market of copyrighted goods manufactured abroad.
• He represented 36 law schools in a high-profile Supreme Court case against the Department of Defense.

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. Before that, Josh founded the Office of the Appellate Defender, a public defender office specializing in criminal appeals.

Irena Royzman, Ph.D. Partner

New York

With a Ph.D. in biology from MIT and the Whitehead Institute, where she was a NSF fellow, Irena represents plaintiffs and defendants in their most complex pharmaceutical and biotech patent cases. Over the last 20 years, pharmaceutical and biotechnology innovators have relied on Irena again and again for cases involving small molecules, biologics, recombinant DNA technology, gene therapy, gene editing, manufacturing processes, formulations and drug-eluting medical devices, including numerous multi-billion dollar cases involving many of the world’s best-selling drugs.

Irena has significant experience in litigation under the Hatch-Waxman Act and the Biologics Price Competition and Innovation Act (BPCIA), as well as inter partes review (IPR) proceedings, license disputes and matters with parallel ex-U.S. litigation and proceedings in foreign patent offices. Irena also helps life sciences companies and organizations develop the law in the most important cases for the biopharma industry. She has been principal counsel on numerous amicus briefs to the United States Supreme Court and the Federal Circuit in key biopharma cases.
