"Cleary fails to address in his briefs supporting class certification how he intends to show that he himself suffered a detriment as a result of Philip Morris’ conduct. He likewise does not address how, if at all, his claims are typical of those of class members in this regard. This will not do. As the Court noted earlier, “the [typicality] requirement is meant to ensure that the named representative’s claims have the same essential characteristics as the claims of the class at large.” Oshana, 472 F.3d at 514. By failing to address how he or any other class member will prove that they suffered a detriment due to Philip Morris’s alleged misconduct, Cleary has effectively forfeited the point. Even were this not the case, the Court would conclude that Cleary has failed to establish typicality. Class C is defined so broadly that it is likely to include persons who suffered no detriment at all due to Philip Morris’s conduct. Some class members may have purchased Marlboro Lights for reasons wholly unrelated to its purportedly less-unhealthy qualities – for example, because they preferred the flavor over other brands. And other class members may have purchased Marlboro Lights despite being completely unaware of claimed differences between the adverse effects of “light” cigarettes and other, non-“light” brands. It is not entirely clear where Cleary fits in along this spectrum. Though it is true, as Cleary points out, that factual differences among the claims of class members do not necessarily defeat typicality, see Rosario, 963 F.2d at 1018, the likelihood that some significant proportion of class members experienced no injury at all does, at least in a case like this one in which proof of detriment is a necessary element of the claim."
