engagement of the bolt with the target obtained by the
interaction of the head of the bolt with the countersunk hole
(Brief, page 5).
Appellants’ argument is not persuasive. We agree with
appellants that the holes in the target of Fujitsu are not
threaded because threads are unnecessary, but for different
reasons than stated by appellants. The screw 14 of Fujitsu goes
through the holes in the target 11 and is anchored in the backing
plate 12 (see Figure 2). No threads are necessary in the holes
through the target 11 of Fujitsu since threads in the backing
plate would anchor the screw 14 and allow it to achieve its
function of securing the target to the water-cooling backing
plate (translation, page 4).3 However, considering the teachings
of the prior art as a whole, we agree with the examiner that it
would have been obvious to one of ordinary skill in this art to
have provided threaded holes in the target of Fujitsu to secure
the base plate to the target with screw bolts for easy and rapid
replacement as taught by Zejda. See In re Keller, 642 F.2d 413,
3We note some minor errors in the translation, e.g., “the
water-cooling packing plate” (page 4, ll. 6-7 and 17), and “the
water-cooling packing blade” (page 4, l. 15)(underlining added).
We believe it is clear that “12" in Figure 2 should be a water-
cooling backing plate. See the abstract accompanying the
original document.
