"Thank you." It's one of the most oft uttered phrases in the English language and in many cases has nothing to do with banking. But Citigroup is pretty sure that when people hear "thank you" they think Citi and not just "thank you" but any variations thereof. So if At&T thought it was just gonna waltz in and start using using the word "thanks" in its biz, it thought wrong!
Citigroup Inc (C.N) on Friday sued AT&T Inc (T.N), saying the phone company infringed its trademarks in the phrase "thankyou" by using the terms "thanks" and "AT&T thanks" in a new customer loyalty program. The fourth-largest U.S. bank filed its complaint in the U.S. District Court in Manhattan. It seeks a halt to any infringements, triple and punitive damages and other remedies.
