Appeal No. 2003-1246
Application 08/393,617
In the absence of a teaching that ZnO and PbO would be
expected to be equivalent in Snell's glass compositions, we do
not reach the question of whether the known toxicity of PbO would
have motivated one skilled in the art to substitute ZnO for PbO
in Snell's solder glass compositions.
Accordingly, we are reversing the rejection as to claim
1 and also as to claims 2-4, which stand or fall therewith.
