John B. Quinn is one of the most prominent business trial lawyers in the United States. As Chambers put it in their guide to U.S. lawyers and law firms: “‘Tough guy’ John Quinn is ‘confident and quick’ say clients. Opponents acknowledge his ‘convincing courtroom demeanor’ and one even named him ‘literally the best I have ever faced in the past half dozen years.’” This sentiment echoed The American Lawyer’s 2006 feature article, which described the Am Law 100 firm that Mr. Quinn built from scratch as “Better. Faster. Tougher. Scarier”. (“The Mighty Quinn, John Quinn Is in Better Shape Than You Are. Now He Wants to Eat Your Lunch”, The American Lawyer, 2006.) Or, as further summed up by his clients in Chambers—“there is no other”. He has been described by the Los Angeles Daily Journal as a “legal titan” and by Chambers as a “known litigation genius”.
He has been named "One of the World's Leading Litigation Lawyers" by Euromoney Institutional Investor; "One of California's Leading Litigators" by Chambers; "One of the Top 3 Trial Lawyers of Choice by General Counsel in California" by California Law Business; one of the "Outstanding Trial Lawyers of America," by Chambers U.S.A., in 2003 and 2004; "One of the Top 15 Litigators in California" by the Los Angeles Daily Journal ; "One of the Top 45 Lawyers Under the Age of 45 in the United States" by The American Lawyer (when he was under 45); "One of the 100 Most Influential Lawyers in California" by California Law Business, 2000, 2001 (one of 9 business litigators so named); a “Litigation Star” by Benchmark Litigation; a First Tier “Leading Trial Lawyer” by The Legal 500 USA; and a "Super Lawyer" by Los Angeles Magazine. In 2003 he won the largest jury verdict awarded to individual plaintiffs (source: AP). In 2009, he was named "California Attorney of the Year" for "extraordinary achievements" in intellectual property law by The California Lawyer for his work on the highly publicized litigation for Mattel, Inc. over the "Bratz" line of dolls. In 2013, he was named one of "The 100 Most Influential Lawyers in America" by The National Law Journal and one of The American Lawyer's "Top 50 Most Innovative Lawyers" over the past half century. In 2015 and 2017, he was named “Transatlantic Law Firm Leader of the Year” at The American Lawyer’s Transatlantic Legal Awards.
Since 1987, Mr. Quinn has also been General Counsel of the Academy of Motion Picture Arts and Sciences, the organization that awards the Academy Awards.
