T-Mobile US has won a battle to prevent major rival AT&T from using its trademark magenta colour scheme in its own marketing material.
The U.S. mobile operator on Saturday said it was "pleased" with the decision by the federal court in Texas that the use of the magenta colour by Aio Wireless, an AT&T unit, infringed on T-Mobile's trademark.
"The court agreed with us that Aio can't continue infringing T-Mobile's magenta mark by using large blocks of what it has called 'plum,' and told Aio to stop using magenta or similar colours in all of its marketing and advertising," T-Mobile US said in a statement.
We presume that Aio has complied with the ruling, since there is not an excessive amount of magenta, plum or pink of any kind on its Website at present.
"The Court's ruling, coming after extensive argument and a three-day hearing, validates T-Mobile's position that wireless customers identify T-Mobile with magenta and that T-Mobile's use of magenta is protected by trademark law," the telco added.
