The rejection
The examiner correctly identifies the three differences
between Ishii and the subject matter of claim 1 (FR3; EA3). The
examiner finds that Steenblik discloses the claimed stereoscopic
lenses and a pattern having at least one portion having a color
greater than approximately 5000 Å (FR3; EA3-4), i.e., the subject
matter of differences (1) and (2). The examiner finds that Ishii
and Steenblik use similar techniques to create stereoscopic
images, because they both use how different colors will behave
when reflected or refracted based on their different wavelengths,
referring to column 3, lines 45-55 of Ishii and figures 4a-4c of
Steenblik (FR32; EA4). The examiner concludes that it would have
been obvious to view the pattern of Ishii with the stereoscopic
lenses of Steenblik and to make the pattern of Ishii with at
