Claims are supposed to be construed without any reference to the thing that has been accused of infringing. SRI Int'l v. Matsushita Electric Corp., 775 F.2d 1107, 1118 (Fed. Cir. 1985). The en banc Federal Circuit held: "[C]laims are not construed 'to cover' or 'not to cover' the accused device. That procedure would make infringement a matter of judicial whim. It is only after the claims have been construed without reference to the accused device that the claims, as so construed, are applied to the accused device to determine infringement."
