In its complaint filed in the U.S. District Court in Manhattan, Citigroup said it has since 2004 used “thankyou” extensively in promoting its own customer loyalty and reward programs, including credit cards co-branded with AT&T.

But the New York-based bank, the nation’s fourth-largest by assets, said the “AT&T thanks” program launched on June 2 will likely confuse consumers, and irreparably damaged its goodwill and reputation associated with the “thankyou” trademarks it uses for various banking services.
The lawsuit seeks to stop AT&T from using the phrases “thanks” and “AT&T thanks” in its programs and marketing. It also seeks unspecified triple and punitive damages.
AT&T plans to defend against the lawsuit, spokesman Fletcher Cook said.
“This may come as a surprise to Citigroup, but the law does not allow one company to own the word ‘thanks,'” Cook said. “We’re going to continue to say thanks to our customers.”
Liz Fogarty, a Citigroup spokeswoman, declined to provide additional comment.
Citigroup said its “thankyou” programs have about 15 million members in the United States, and that 1.7 million customers there have credit cards co-branded by Citigroup and AT&T.
