There is no United States Copyright and Trademark Office.
Gen X Radio said:You guys need to brush up on your trademark law. "prior use in commerce" is all that is required in the US to own a trademark.

Gen X is exactly right with regard to common law trademark rights. However, what I would be concerned about is CC filing a declaratory judgment action. Such actions make potential plaintiffs into defendants.
In the US, a recipient of a cease-and-desist letter who is placed in a "reasonable apprehension" of litigation may respond through a request for declaratory judgment proceeding in his own jurisdiction.
