Appeal No. 1998-2775
Application 08/574,544
35 U.S.C. § 102(b) as being anticipated by Lewis, and
appealed claim 5 stands rejected under 35 U.S.C. § 103 as
being unpatentable over Lewis. Appealed claim 5
additionally stands rejected under 35 U.S.C. § 112, second
paragraph, as being indefinite for failing to particularly
point out and distinctly claim the subject matter which
appellants regard as their invention.
Considering first the § 102(b) rejection of claim 6,
Lewis discloses an artificial leg having a thigh section A
and a lower leg portion D attached to the thigh section by a
pair of strap assemblies. Each strap assembly in Lewis’
artificial leg has pivotally interconnected upper and lower
metal straps E and F to allow pivotal movement between the
thigh section and the lower leg portion. The upper straps E
of the two strap assemblies are fastened to the thigh
section. The lower straps F of the strap assemblies are
attached to the lower leg portion. Contrary to appellants’
arguments, the lower straps F are considered to be embedded
in the lower leg portion in that they appear from the
showing in Figure 1 of Lewis’ drawings to be received in
upwardly opening pockets in the lower leg portion.
