sentence). For this teaching, the examiner relies upon Landis
for teaching the desirability of applying an image to a first
plate cylinder while a second plate cylinder is in a printing
position and subsequently activating and imaging the second plate
cylinder while the first plate cylinder is in a printing position
(page 4 of Answer, second paragraph).
The flaw in the examiner's position, as explained by
appellants, is that Landis does not teach "throwing-off a single
plate cylinder of a single printing unit while another is
printing in the same printing unit but rather disclose throwing-
off a complete printing unit which means that both blanket
cylinders are separated from the web and that the web is thus not
printed on either side" (sentence bridging pages 3 and 4 of Reply
Brief). Appellants correctly state that the printing press of
Landis "includes a plurality of printing units and that during a
printing run some of the printing units are in a printing mode
while others are thrown-off" (page 3 of Reply Brief, last
paragraph). Stated otherwise, "[n]owhere do Landis et al.
disclose, or even suggest, the timing of throwing-off individual
elements within a given printing unit" (page 4 of Reply Brief,
second paragraph, emphasis added).
