Appeal No. 1999-1657
Application No. 08/877,781
Greenspan . . . discloses a method and apparatus for
enlarging images without using lenses (microprisms)
by utilizing a plurality of reflective surfaces. . .
. Instead of using lenses to magnify the projected
image, Greenspan uses reflective surfaces 46, 70 and
80 (Figure 2) to enlarge the image.
We find that Greenspan merely enlarges the size of each
pixel via reflection, and does not create a plurality of
pixels corresponding to each original pixel of the display,
while keeping the created plurality of pixels separated by a
nonzero gap. Furthermore, the combination of APA and
Greenspan also does not meet the recited limitation “an
optical filter surface . . . for diffusing each pixel of said
display device into a plurality of parts by utilizing
deflection or refraction”. Therefore, we do not sustain the
obviousness rejection of these claims over APA and Greenspan.
In conclusion, we have not sustained the rejections of
claims 1 to 3, 5, 7 to 9, 11, and 13 to 17 under 35 U.S.C. §
103 over either APA, or APA and Greenspan.
Accordingly, the decision of the examiner rejecting these
claims under 35 U.S.C. § 103 is reversed.
