on each side of the plane of the web.3 To overcome this
deficiency, the examiner looks to Guaraldi.
Guaraldi discloses a printing unit operable to print on both
sides of a web. To this end, the unit includes upper and lower
printing and blanket cylinders (see Figures 1, 3 and 4) arranged
as set forth in appealed claim 1, i.e., one above another and
having respective axes which lie in a common plane inclined at an
obtuse angle to the plane of a printing web with at least one
cylinder lying on each side of the plane of the web.
In proposing to combine Fadner and Guaraldi to account for
the printing cylinder arrangement specified in claim 1 and
missing in Fadner, the examiner submits that it would have been
obvious to one of ordinary skill in the art “to construct the
invention of Fadner with printing unit cylinders on each side of
the web, as taught by Guaraldi et al., in order to be able to
print on both sides of the web at the same time” (answer, page
5).

3 Although Fadner’s Figure 2 shows an unnumbered printing
cylinder which is on the opposite side of the web from the
printing and blanket cylinders and has an axis that defines with
the printing cylinder axis a common plane inclined at an obtuse
angle to the plane of the web, the unnumbered cylinder and the
printing cylinder are not arranged “one above another” as recited
in claim 1.
