Quinn Emanuel Urquhart & Sullivan, LLP

Quinn Emanuel Urquhart & Sullivan, LLP’s appellate practice is heavily intertwined with its trial group, which sees the firm’s key trial lawyers often working in tandem with appellate specialists in courts of appeals nationwide. Likewise, appellate advocates are often embedded in early-stage trial teams in preparation for potential appeals. Seasoned senior counsel Kathleen Sullivan steers the department and splits her time between Los Angeles and New York; she successfully represented Block before the Eighth Circuit in a trademark infringement case brought by H&R Block and HRB Innovations. In a significant Florida Supreme Court case, John Bash represented Smart & Safe Florida in defending a ballot initiative that would allow Florida voters to choose whether to amend the state’s constitution to permit adults’ personal use of marijuana—he operates from Austin and Washington DC. The group also draws on the experience of New York-based energy litigation specialist Sanford Weisburst and Washington DC-based Derek Shaffer, who has a focus on government and regulatory litigation.
