According to the Sanofi case which was brought up by poster Orkafit (can moderator kindly stickied his fine post):
"The Sanofi Court concluded that Defendants' labels would encourage SOME physicians to prescribe the drug to patients with risk factors, and will thus inevitably lead to infringing uses. The Court expressly stated: "[e]ven if [Defendant] were correct that the [language in the label] may be applied to other dosing regimens, the language ... would inevitably lead some consumers to practice the claimed method." The Sanofi decision clearly emphasizes the legal standard, i.e., that the proposed label would inevitably lead SOME physicians to infringe."
