Appeal No. 1997-4387
Application 08/308,963
Appellants' independent claim on appeal calls for a
quadrilateral linkage defining a pantograph having the form of
a collapsible rhombus wherein said rhombus exhibits two
first vertices lying on a vertical line and two second
vertices lying on a horizontal line. We view this recitation
as misdescriptive of appellants' claimed linkage. Appellants'
specification at page 7 clearly admits that the rhombus link
members are not directly pinned with each other. Although the
appellants state that their pantograph structure is
"essentially" a rhombus, appellants fail to establish the
metes and bounds of the claim when they argue that the
pantograph structure in Figure 5 of Goto is not substantially
similar to
their structure because of separation of the top vertices of
arms 101 in Goto.
