· Katy Perry lost a long-running legal battle against an Australian fashion designer with the same name.
· The case centered on designer Katie Perry, who spells Katie with "ie."
· She launched a clothing label under her own name in Australia and applied for a trademark for clothing in 2008.
· In 2009, Perry's legal team sent a cease-and-desist letter arguing the brand name conflicted with the singer's trademark and could confuse customers.
· The dispute dragged on for more than a decade and moved through several courts in Australia.
· This week the High Court of Australia ruled the designer's label does not violate the singer's trademark and she is allowed to sell clothing under her own name.
· After the ruling, designer Katie Perry said the legal fight had weighed on her for years and she felt relief now that the issue is settled.
· She said the case had created "heaviness, fear, and limbo" since 2009 and added that she is excited to finally focus on the future of her brand.
