Appeal No. 2002-1609
Application 09/129,238
nickel and chromium of at most 0.08%, at most 0.006% carbon and
at most 0.010% aluminum, iron, and inevitable impurities,
casting the steel in the form of a slab,
-hot rolling the slab at a temperature above Ar3 to obtain a
strip of hot-rolled sheet,
-coiling the hot-rolled sheet,
-cold-rolling the hot-rolled sheet into the form of an
intermediate cold-rolled sheet,
continuously annealing the intermediate cold-rolled sheet at
a temperature between 640ēC and 670ēC,
rerolling the intermediate cold-rolled sheet down to a final
sheet thickness for drawing, wherein said hot-rolled sheet is
coiled at a temperature between greater than 530ēC to 570ēC, and
wherein said process provides a sheet of ultra-low-carbon steel
comprising at most 0.001% titanium and at most 0.001% niobium and
having a Lankford coefficient raver greater than 1.6.
The examiner relies upon the following reference as evidence
of unpatentability:
Fujinaga et al. (Fujinaga) EPO 0 556 834 Aug. 25, 1993
Claims 8-17, 19, and 21 stand rejected under 35 U.S.C. § 103
as being unpatentable over Fujinaga.
On page 3 of the brief, appellants state that the claims do
not stand or fall together, and provide arguments in support
thereof. We therefore consider each of the claims. 37 CFR
§ 1.192(c)(7)(2000).
