Appeal No. 1998-1349 Page 7
Application No. 08/455,859
We turn next to the examiner’s rejection of claims 2 and
4 under 35 U.S.C. § 102(b) as being anticipated by Young. In
the view of the examiner, Young anticipates the claimed
invention of claims 2 and 4 because:
In Fig. 3 of Young, 4 is the central panel,
the planar wall is shown at lead line 3, 8
is the flange and 7 is the cover hook, as
stated in claim 2. With respect to claim
4, the annular portion is shown at lead
line 3 and 7 is the curl. [examiner’s
answer at page 4].
Appellants argue that Young describes the in-turning or
curling of the outer edge of the flange 5 as shown as 7 in
Figure 3 and thus Young leads away from the unique product of
the present invention in which the outer curl is stretched
outwardly during forming to thin the curl.
Claim 2 recites:
the cover hook and the peripheral edge being formed
in a single station by cutting the peripheral edge,
moving the peripheral edge downward and inward and
forming a transitional wall between the flange and
the peripheral edge, and moving the peripheral edge
upward and extending the transitional wall outward
for forming the cover hook.
