  • Defended Speedo USA, the US distributor of the Speedo brand swimsuit, in a false advertising, Lanham Act, antitrust and unfair competition case brought by a competitor over the marketing and promotion of the Speedo LZR, the revolutionary competitive racing suit worn by more than 70% of the medalists at the 2008 Summer Olympics in Beijing. Plaintiff, Speedo's primary competitor in the sale of competitive racing swimsuits, sued in the US District Court for the Central District of California for false leading advertising, Lanham Act violations, monopolization, exclusive dealing and other alleged torts. Plaintiff claimed that Speedo misrepresented the test results of swim time improvements achieved using the LZR Racer. Plaintiff also claimed that Speedo's sponsorship of USA Swimming—the national governing body for amateur swimming in the United States—and its head coach gave Speedo an unfair advantage in marketing its suits to elite swimmers and other swimmers who race. After a motion to dismiss, in which some of plaintiff's claims were dismissed, the parties engaged in extensive discovery. Following two motions for summary judgment, plaintiff's remaining claims were dismissed. Plaintiff did not appeal.
