answer:It depends on the way they are using the phrase. If it is just an internal thing, then there wouldn’t be any likely repercussions. This article explains a bit more: A trademark does not mean, however, that no one else can use your word, phrase, or symbol in connection with any and all goods and services. It means only that somebody else can’t use a similar trademark with similar goods or services. The key criterion: trademark infringement occurs when someone else’s use of a trademark would likely cause confusion about the source of goods or services. Avon, for example, has trademarked “Let’s talk” for a variety of commercial uses, including door-to-door retail merchandising. But that hasn’t stopped another company from trademarking “Let’s talk” for use with voice-activated computer software, because consumers are unlikely to get confused and believe that Avon is pitching software, or that a software company is hawking lipsticks.
