Katie Perry vs Katy Perry: Australian designer wins trademark over popstar; CNN, March 11, 2026

Lex Harvey, Angus Watson, CNN; Katie Perry vs Katy Perry: Australian designer wins trademark over popstar

"Sydney-based fashion designer Katie Perry had always dreamed of starting her own clothing brand. She never imagined a global pop star would be her biggest obstacle.

But on Wednesday Australia’s highest court ruled that Perry, who now goes by her married name Katie Taylor, has the right to sell clothes under her own name.

It’s a major victory for the underdog small business owner, who more than 15 years ago received a letter from the other Katy Perry — yes, that one."

Katy Perry's Met Ball dress the subject of copyright infringement lawsuit; Guardian, 8/6/15

Tshepo Mokoena, Guardian; Katy Perry's Met Ball dress the subject of copyright infringement lawsuit:

"One artist is less than impressed with the dress that Katy Perry wore to this year’s Met Ball – and not for sartorial reasons. Brooklyn street artist Rime, born Joseph Tierney, has filed a copyright infringement lawsuit against designer Jeremy Scott and design house Moschino, for making a dress that Tierney believes imitates a signature graffiti tag that he painted on a Detroit building."
