I had to verify this on several websites because it seemed like an April Fool’s joke but it checks out:
Citigroup Inc sued AT&T Inc on Friday, saying the phone company’s use of “thanks” and “AT&T thanks” in a new customer loyalty program infringed its trademark rights to the phrase “thankyou.”
Yes, Citi trademarked thankyou. No space! What an innovation! Now they are suing because AT&T has a similar customer loyalty program using “thanks” and “AT&T thanks”.
The IP system is out of control.
