Appeal No. 95-1296
Application 08/073,257
[column 1, lines 18-21]. Fitzgerald not only suggests that there
are different types of tolerances such as linear and angular, but
also that the tolerances associated with such a model are
selected from standards published by the American Society of
Mechanical Engineers. Thus, Fitzgerald would have suggested to
the artisan the obviousness of selecting and placing any of the
various types of tolerances which were typically placed on models
on the models of Fitzgerald. In other words, it would have been
obvious that any tolerances which could be selected in the prior
art models were also selectable for the Fitzgerald models. Thus,
we disagree with appellants’ argument that Fitzgerald teaches
that only a single type of tolerance is selected.
With respect to claim 10, appellants argue that
Fitzgerald does not teach the step of “defining a face” nor the
step of “linking” [brief, pages 8-10]. With respect to the
former step, we fail to see how the faces of the solid object in
Fitzgerald, which are stored in memory with respect to a local
coordinate system [note FIG. 10A, box 110], can be stored without
defining their mathematical relationship to the datums of the
coordinate system. In other words, the faces of the solid object
in Fitzgerald are clearly stored in memory in the form of a
mathematical relationship to a local coordinate system.
