Appeal No. 95-0840
Application 08/029,343
Appellants have appealed to the Board from the examiner’s
final rejection of claims 27 to 32, 34 to 40 and 42 to 51, which
constitute all the claims remaining in the application.
Representative independent claim 27 is reproduced below:
27. A non-additive mixer for video signals, comprising:
a first chrominance filter for receiving a first video input
and producing a first luminance signal;
a second chrominance filter for receiving a second video
input and producing a second luminance signal;
summation means coupled to receive the first luminance
signal and the second luminance signal and producing a mixer
control signal that is a linear function of the difference
between the first luminance signal and the second luminance
signal; and
a mixer coupled to receive the first video input and the
second video input and producing a video output representative of
the product of the first video input and the mixer control signal
plus the product of the second video input and the complement of
the mixer control signal.
There are no references relied on by the examiner.
All pending claims stand rejected under the first paragraph
of 35 U.S.C. § 112 as being based upon a non-enabling disclosure,
as well as the second paragraph of 35 U.S.C. § 112 since, in the
examiner’s view, the claims fail to particularly point out and
distinctly claim the subject matter which appellants regard as
their invention.
