teaches that the “target 1 and base plate 2 are secured together
by means of screw bolts 14.” Col. 2, ll. 66-67; see also Figure
1. As admitted by appellants, Zejda brings the screw bolts into
the target from the backing plate (rear) side (Brief, page 8).
Accordingly, we determine that it would have been well within the
ordinary skill in this art to bring the screw bolts into the
target from the backing plate side in the sputtering target
device of Fujitsu (with the threaded holes in the target), as
taught by Zejda, for a rapid and simple replacement system.4
Appellants argue that Fujitsu inserts the target mounting
bolts from the sputtering (inner) side of the target and would
not arrange the bolts as taught by Zejda since the magnets and
accompanying mechanism “will crowd the rear side of the
target/backing plate assembly” rendering the bolts less
accessible (Brief, page 7). Again we note that this argument is
“mere attorney argument” unsupported by any evidence of record or
convincing reasoning. See In re Scarborough, supra.
Appellants’ only argument with respect to Inoue is that this
reference teaches away from a single material target (Brief, page
9). This argument is not well taken for several reasons. First,
4We note that the screw bolts of Zejda need only be
partially removed to allow replacement of the target.
