said frequency spectrum.”
The 35 U.S.C. § 102(e) rejection of claims 32 through 34 and
38 is reversed because Ishikawa does not disclose: “filter means”
for filtering a composite video signal into a first frequency
band including a chrominance signal and a first luminance signal
component, a second frequency band including a second luminance
signal component, and a third frequency band including a third
luminance signal component, with the first frequency band
containing higher frequencies than the second frequency band, and
the third frequency band containing lower frequencies than the
second frequency band; and “means for generating a transposed
luminance signal by transposing frequencies of said second
luminance signal component into said first frequency band so as
to fold said second luminance signal component into said first
frequency in accordance with a first carrier having a phase that
alternates from field-to-field but not from line-to-line.” The
claimed fields and lines are set forth in Table 1 of appellant’s
disclosure (specification, page 13).
Turning next to the 35 U.S.C. § 103 rejections, we find that
