Designer Katie Perry Triumphs in 16-Year Trademark Clash with Katy Perry

Australian designer Katie Perry (Katie Taylor) wins a 16-year trademark battle against pop star Katy Perry: the High Court’s 3-2 ruling finds the singer’s fame wouldn’t mislead consumers into linking Katie Perry’s clothing with her brand, upholding Katie Perry’s trademark while noting that Katy Perry’s label had been assiduous infringers by selling clothing in Australia; the case will return to the Full Federal Court for remaining issues.
