Appeal No. 95-1220
Application 07/972,279
argue on page 9 of the brief that neither Boone nor Peppers
teaches “two fixed masks, a first mask containing a first
pattern comprising a series of rotated radial slits and a
second mask containing a second pattern comprising a plurality
of annuli having different diameters, the first and second
fixed masks for passing the replicated images therethrough and
extracting the boundary of the object.”
Upon a review of Boone and Peppers, we fail to find
these limitations as well. The Examiner points to the
teaching found in Peppers, column 11, lines 7-14 [sic, 7-15].
Upon review of this portion of Peppers, we note that Peppers
teaches that the primitive masks 6a may include a T-shaped
slit, an oblique slit, a loop slit and a radial slit as well
as horizontal, vertical and cross-shaped slits. We fail to
find that this teaching meets a series of rotated slits as
recited in Appellants’ claim 3 or the two fixed masks as
recited in Appellants’ claim 20.
In regard to claims 24 and 7, Appellants further
argue that it would not have been obvious to modify Boone as
proposed by the Examiner with the Peppers teachings. We note
