Appeal No. 96-4080
Application 08/396,541
structure for pixel arrays which include CMOS gates and
suggests alternative pixel shapes and geometries such as
hexagonal arrays are suggested. In addition, we agree with
the Examiner that Bulucea teaches a power MOSFET apparatus
using a hexagon-shape trench in which the gate is positioned
in order to suppress oxide and that Sedra teaches a CMOS NAND
gate. However, neither Huang, Buluccea nor Sedra teaches or
suggests arranging a hexagonal ANY element and a hexagonal ALL
element of an opposite conductivity of the conductivity of the
ANY element in which one of said first through sixth edges of
the ANY element is common with one of the first through sixth
edges of the ALL element as claimed by Appellant.
We are not inclined to dispense with proof by evidence
when the proposition at issue is not supported by a teaching
in a
prior art reference, common knowledge or capable of
unquestion-able demonstration. Our reviewing court requires
this evidence in order to establish a prima facie case. In re
