> But in a 9-0 decision, the justices said a precedent known as the Rogers test for assessing the use of trademarks in artistic expression did not apply to VIP's products, reversing a U.S. appeals court
> The Rogers test is "not appropriate when the accused infringer has used a trademark to designate the source of its own goods - in other words, has used a trademark as a trademark," Justice Elena Kagan wrote.
> The whiskey maker will still have to prove VIP's toys are likely to confuse potential customers into thinking it was affiliated with them in order to win its infringement case.
