Appeal No. 1996-2758
Application No. 08/103,792
Appellants also argue that Horiba would not have
suggested the claimed molar ratio of a quaternary ammonium ion
to an aluminum halide. See Brief, page 8 and Reply Brief,
page 7. We disagree. As indicated supra, Horiba teaches
using an electrolyte containing amounts of a quaternary
ammonium ion and an aluminum halide, which can be dissolved in
an organic solvent, such as 1, 2-dichloroethane, and can be
useful for improving the conductivity characteristic to an
electrode used in a secondary battery cell. Implicit in this
teaching is that the amounts of a quaternary ammonium ion and
an aluminum halide employed must be sufficient to impart the
desired dissolution and conductivity characteristics. In
other words, Horiba establishes that the amounts of a
quaternary ammonium ion and an aluminum halide ion employed
are result effective parameters in the secondary battery cell
art. Therefore, the determination of workable or even optimum
values for these parameters would have been obvious to one of
ordinary skill in the art. In re Woodruff, 919 F.2d 1575,
1578, 16 USPQ2d 1934, 1936-37 (Fed. Cir. 1990); In re Boesch,
617 F.2d 272, 276, 205 USPQ 215, 219 (CCPA 1980).
