November 2007: T-Mobile claims trademark on the color magenta.
August 2013: Out come the lawyers:
Chances are you probably don’t even know about AT&T’s Aio Wireless prepaid service, as it’s currently only available in a handful of markets. But the folks at T-Mobile have sued the subsidiary now before the world gets confused by two phone companies that use similar colors.
In a lawsuit [pdf] filed last week in a U.S. District Court in Texas, T-Mobile alleges “trademark dilution, trademark infringement and unfair competition with regard to T-Mobile’s trademark rights to the color magenta in the field of telecommunications services.”
T-Mobile claims that Aio was a deliberate and immediate response to its decision earlier this year to do away with phone subsidies and allow customers to get wireless plans without two-year contracts.
So far as I know, Pantone has not been asked for a statement, or even a color sample.
