For infringement to occur, does it need to "encourage / promote" or is "encourage / promote" only a subset of "make use possible", because without "make use possible", there is no "encourage / promote" ... sort of like what came first, the chicken or the egg?
Did "encourage / promote" come from a statute or from judge's opinion (case law)? Please cite it, if you have it.
Because they are not allowed to reference R-IT label. If the do - in any way - they'd be infringing on that indication, as it is not within the skinny label that they are approved for.
