A Sydney fashion designer who won a Federal Court stoush against US pop star Katy Perry says she is "over the moon" at the verdict.
Legal action was first launched in June 2009 over a trademark held by Katie Jane Taylor, who uses her birth name to design and sell clothes under the brand Katie Perry.
Ms Taylor has run her fashion label since 2006, which she describes as a dream come true made possible through "blood, sweat and tears".
