Batman Cologne?

The logo for the line of Gucci Guilty items strikes me immediately as a Bat-symbol. I am not by nature litigious and I don't customarily give business advice to multimillion dollar corporations but, if I were DC Comics, I would either sue Gucci to cease and desist or else demand that DC receive a cut of the profits. While in negotiations maybe the two companies could agree to tweak the Guilty logo ever-so-slightly and legitimately call the stuff Gucci Batman. Why not?
