Remember when we reported that T-Mobile was suing AT&T because the marketing for the Aio budget carrier used a shade of purple that was too close to T-Mobile's (literally) trademark magenta? Yes, that is a thing that happened. And apparently at least one Texas judge thought it was a valid complaint, because a federal court has ruled that Aio did, in fact, infringe on T-Mobile's corporate trademark.

Here's the PR statement that T-Mobile issued after the ruling:

Federal Court Rules that AT&T was Infringing on T-Mobile's Magenta Trademark Color and Orders an Injunction

A federal court has halted AT&T's transparent effort to infringe on T-Mobile's distinctive magenta trademark.
