The United States International Trade Commission (ITC) is an increasingly popular venue for patent infringement litigation. More and more companies are seeking to halt importations of infringing products into the United States by turning to the ITC for expedited relief.

Winston Wins Ninth Circuit Reversal and Class Certification in Swimmers’ Antitrust Case, Securing a Global-Impact Settlement with World Aquatics

Winston represents a class of professional swimmers alleging World Aquatics (WA) violated antitrust laws by blocking their participation in the competing  International Swimming League.
