Intellectual property is global.  Intellectual property law, however, is national -- which may cause difficulties for New York State, a determined defender of its "I Love NY" U.S. trademark, with respect to this version from Nancy, France:

It's a toss-up whether the original trademark owner will be more offended by Nancy's use of the mark or by the fact that the interloper -- like many people -- apparently believes that the slogan refers to New York City rather than the whole state.  At the moment, however, New York definitely does not "heart" Nancy.
