Appeal No. 98-0594
Application 08/615,461
from which the second metal housing is made (such as
aluminum alloy, see column 2, lines 16-20) into the
second metal housing, (via filling opening 3) around
the first metal element.
The appellant’s claimed invention is more than connecting
two elements already made, with each other, by placing molten
material therebetween. The above-quoted teaching from Jordan
does not disclose or reasonably suggest placing a first
element within the die casting used to form the second element
such that the connection between the first and the second
element is made when the second element is formed by hardening
molten material in the die casting for the second element.
Finally, on page 5 of the answer, the examiner does begin
to discuss the appellant’s claimed invention. The examiner
states:
[L]ocating preforms or other parts into a die
casting mold before introducing molten material so
as to connect the multiple preforms and the molded
object during fabrication is also a notoriously old
and well known methodology. An entire subclass has
been devoted to such fabrication in class 164 (Metal
Founding), subclass 98, the designation of which is:
Process . . . Shaping liquid metal against a forming
surface . . . Composite article forming . . .
Shaping metal and uniting to a preform (i.e. onto a
self-sustaining body). To use such a method to
create the base and cover would have been obvious to
one of ordinary skill in the art as an efficient way
to connect the parts without additional fasteners or
manufacturing steps.
