Sheppard Mullin’s intellectual property group prevailed before the United States Supreme Court in the trademark matter entitled Hana Financial v. Hana Bank. 574 U.S. ___ (2015). Justice Sotomayor, writing for a unanimous court, affirmed a Ninth Circuit ruling that the doctrine of trademark tacking presents a question of fact appropriate for jury determination. 735 F.3d 1158 (9th Cir. 2013). This was the first substantive trademark decision by the U.S. Supreme Court in nearly a decade. Partner Carlo Van den Bosch argued the case before the Supreme Court on behalf of client Hana Bank, who he has represented since the initial filing in 2007 in California federal court.
