T-Mobile Wins Lawsuit Against AT&T Over the Colour Purple:

T-Mobile USA says that it has won a lawsuit against AT&T over the colour purple.

T-Mobile has long used a shade of purple for its brand, and when AT&T launched its own low-cost service, branded Aio Wireless, it was also used a purple shade -- which it called plum.

The core of the argument centred on the fact that Aio Wireless is a prepay service, and was launched around the same time that T-Mobile revamped its services into a more prepay like format.

In the court filing, T-Mobile accused that "Aio does not use the orange coverage map of its parent company, but instead uses in its stores and on its website a magenta coverage map that is strikingly similar in color to the one used by T-Mobile."

The court has now agreed with T-Mobile.
