Appeal No. 95-5093
Application 08/047,132
Watkins, "Development of CABAL glasses for Use in Lithium
Ambient-Temperature Batteries," abstract, SAND--87-0393
Appellants' claimed invention is directed to an electrical
device that is designed for implantation in a human body. The
device comprises, inter alia, an electrical terminal consisting
of a material, such as platinum, which extends through an opening
in a container, and a glass insulator in sealing engagement with
a portion of said terminal and said container. The glass
insulator has a chemical composition consisting essentially of
Al O , CaO, B O and SiO . The glass composition may also contain2 3 2 3 2
MgO, BaO and SrO. The SiO is present in an amount between about
2
10 mole % and 15 mole %.
Appealed claims 1 and 3-7 stand rejected under 35 U.S.C.
§ 103 as being unpatentable over Taylor in view of Kyle, three
Watkins abstracts and Kraska.
Upon careful consideration of the opposing arguments
presented on appeal, we concur with appellants that the examiner
has failed to establish a prima facie case of obviousness for the
claimed subject matter. Accordingly, we will not sustain the
examiner's rejection.
The examiner states at page 5 of the Answer that "[t]he
references do not disclose the exact glass composition used as
the insulating material." We understand this statement to be
