John B. Quinn

Quinn built one of the nation’s most profitable litigation law firms and continues to expand its reach throughout Europe, Asia and Australia. With a new Stuttgart, Germany office, the firm now has 21 offices in 10 countries, which is believed to be the largest litigation-only platform in the world.

The firm handles sprawling and consequential litigation and investigative matters — often with Quinn himself as lead counsel.

The firm is defending Daimler in several antitrust class actions in the U.S. related to alleged collusion among German auto manufacturers over emissions control technology. FIFA hired Quinn to conduct an internal investigation after prosecutors in the United States and Switzerland accused soccer’s governing body of massive corruption. The firm was also retained by financial services giant BTG Pactual to conduct an internal investigation after it was caught up in Lava Jato, or Operation Car Wash, the corruption scandal unfolding in Brazil.

In November, Quinn is scheduled to begin trial in a case relating to the rights to the Japanese action hero Ultraman.

That case likely won’t be as large or as consequential as the patent case that has dominated Quinn’s practice for the last few years. He continues to defend Samsung in its battle with Apple over mobile device technology. He is preparing for a retrial of one portion of that case after the U.S. Supreme Court ruled in Samsung’s favor on the issue of the proper measure of patent damages.
