Aimsterdeviates from Sony
!To trigger the COSNU defense, a defendant must
demonstrate that its product has substantial
noninfringing uses, not merely that it is capable ofsubstantial noninfringing uses
!Even if the defendant makes such a showing, if the
infringing uses are substantial, the defendant must
also show that it would have beendisproportionately costly to design its product so
as to eliminate or reduce the infringing uses
