The team at Quinn Emanuel Urquhart & Sullivan, LLP stands out for its expertise in high profile litigation, including consumer data class actions involving substantial penalties or damages. Its experience includes representing companies faced with data security breaches. Stephen Broome and Viola Trebicka, based across Los Angeles and New York, co-head the practice with New York-based Jennifer Barrett. Barrett, co-managing partner of the New York office, is particularly recommended for data breach response. Broome’s practice is focused on litigating and trying complex disputes, including those related to web-browsers, mobile apps, digital advertising, and facial recognition, with notable appellate experience. Data privacy class actions and data breach litigation, along with breach response, make up Trebicka’s work in the sector; cutting-edge technologies are a specific area of expertise. Also in New York, Jomaire Crawford is noted for her commercial litigation at both a state and federal level, representing a number of big-tech clients.
