Appeal No. 2000-2094
Application No. 08/923,369
Lang to add a high speed A/D converter was ever contemplated or in
fact needed to address the language of the appealed claims.
Similarly, no issue of obviousness exists regarding the replacement
of Lang’s memory 13 with a disc recorder, since Lang explicitly
discloses (column 6, lines 37-39) the utilization of digital
recording media such as optical discs and magnetic discs for memory
13.
In view of the above discussion, it is our opinion that the
Examiner has established a prima facie case of obviousness which
has not been rebutted by any convincing arguments from Appellants.
Accordingly, the Examiner’s 35 U.S.C. § 103 rejection of
representative claim 10, as well as claims 11-16 and 210-27 which
fall with claim 10, is sustained.
Turning to a consideration of the Examiner’s 35 U.S.C. § 103
rejection of claims 28-30, grouped together by Appellants, we
sustain the obviousness rejection of these claims as well. In
addressing the buffering features of these claims, the Examiner has
added the Radice reference to the combination of Lang and Takada.
We find Appellants’ arguments (Brief, pages 11 and 12) to be
unpersuasive since, in our view, Radice clearly contemplates
(column 4, lines 23-29) application of the described buffering
technique to recording media other than video tape.
