Each graphic object is created by the user with a front
polygon (i.e., parent face) and based on a user provided depth
would be drawn with a corresponding back polygon (i.e., offset
face). For each graphic object, when the user creates a front
polygon such action constitutes selecting that polygon as a
parent face. We find that providing more than one graphic
object in a graphic space where each graphic object has a
front polygon and a back polygon meets the Appellants' claimed
language "means for defining two pairs of parallel planes" and
thereby reads on Appellants' limitations in claim 8.
Appellants argues on page 13 of the brief that neither
Himelstein nor Fuller discloses means for determining a
distance between the first face and the offset face.
Claim 17 recites a limitation of "determining a distance
between the first face and the offset face". Appellants'
disclosure on page 13 provides an embodiment where distances
between faces are calculated. However, Appellants chose to
recite the broader term of "determining." One way of
