The complaint draws connections between the launch of Aio, which relies on off-contract plans, and T-Mobile's own switch to off-contract plans, which occurred just months before. "AT&T set up Aio to compete directly with T-Mobile," the complaint reads. It argues that Aio's use of the color magenta "is likely to dilute T-Mobile’s famous magenta color trademark, and to create initial interest confusion." T-Mobile has been using magenta since 2002, but its parent company, Deutsche Telekom, has been using it as far back as the 1990s.
Aio Wireless does use a bright shade of purple, but it's far darker than T-Mobile's hot pink, which it calls magenta. "T-Mobile needs an art lesson," an Aio spokesperson tellsThe Verge. "Aio doesn't do magenta." T-Mobile includes several images in the complaint to illustrate the confusion it's hoping to prove. Among those are both its own and Aio's coverage maps, which display varying shades of purple across the United States.
T-Mobile has previously requested that entities which aren't wireless carriers cease using the color too, including Engadget Mobile back in 2008. Our own Nilay Patel, then writing for Engadget, notes that for such a lawsuit to succeed, T-Mobile would generally have to prove that its own color of magenta was in use, that it was being used in conjunction with a telecommunications product, and that its use could confuse or was intended to deceive consumers.
