deformation is well known as shown by the secondary
reference to Brull. Although Brull may not show the
exact geometries of the claimed invention, but [sic]
any of such geometries is only an obvious
modification of cited art."
We are persuaded by the examiner’s position. We find
that Brull discloses, for instance at col. 2, lines 58 through
60, that each of the coupons (specimens) includes a special
notch pattern comprised of at least one pair of notches
designed to produce a local stress concentration. Brull
further goes on to say that the notch pattern of each of the
coupons produces a stress field which varies in intensity from
relatively mild to very severe. Brull is clearly involved
with testing the specimens and studying the effect of notch
pattern in the concentration of stresses and strains in the
specimen. Therefore, we agree with the examiner that, in
further analysis of the stresses and strains in the Bronowicki
system, an artisan would have found it desirable to introduce
stress concentrators in Bronowicki such as notch patterns as
taught by Brull.
Appellants argue, brief at pages 14 and 15, that "[t]he
examiner cannot apply hindsight so as to find a teaching or
suggestion in the coted [sic] references to establish
