Appeal No. 2002-2274
Application No. 08/387,158
for the reason given above regarding claim 45.2
Claim 52 is rejected under 35 U.S.C. § 103 as being obvious
over Linder in view of the appellants’ admitted prior art,
Apostolos, and JP ‘637.
Dependent claim 52, which depends from claim 51, claims an
alloy comprising about 20% to about 30% Zn, 0.11% to about
0.5% In, about 0.005% to about 0.05% Zr, and the balance Al.
Adding this amount of Zr to Linder’s alloy would have been
obvious to one of ordinary skill in the art in view of JP ‘637
for the reason given above regarding the rejection of claim 45.
Claims 55 and 65 are rejected under 35 U.S.C. § 103 as being
obvious over Linder in view of the appellants’ admitted prior
art, Apostolos, and JP ‘637 or JP ‘128.
Dependent claim 55, which depends from claim 54, claims an
alloy comprising about 20% to about 30% Zn, 0.11% to about
0.5% In, about 0.05% to about 0.3% Si, and the balance Al.
Independent claim 65 claims an alloy consisting essentially of
about 10% to about 50% Zn, 0.11% to about 0.6% In, about 0.05% to
about 0.3% Si, and the balance Al. Adding the amounts of Si
recited in claims 55 and 65 to Linder’s alloy would have been
2 The “consisting essentially of” transition term does not
distinguish claim 63 over Linder as discussed above regarding the
rejection of claim 39.
