The legal proceedings have been going on for almost 17 years, writes The Guardian. But now Australia's highest court has ruled that the designer was not violating any trademark laws.
When designer Katie Perry registered her trademark in 2008, she had not heard of the pop star with a similar name, according to the court. Just a few months earlier, pop star Katy Perry had released her debut single "I Kissed a Girl."
The singer's trademark "Katy Perry" was registered in Australia in 2011. However, the legal battle began in 2009 when the singer filed a complaint against the Australian designer.
