Appeal 2006-2328
Application 10/131,049
NEW GROUNDS OF REJECTION
Claim 57 is rejected under 35 U.S.C. § 103(a) as unpatentable over
Arai and Yamagishi.
Claim 58 is rejected under 35 U.S.C. § 103(a) as unpatentable over
Arai, Yamagishi, and the presumed prior art of Figure 1 of the '443 patent.
Claim 57
The Graham. findings regarding the scope and content of Arai and
Yamagishi and the level of ordinary skill in the art are discussed in
connection with the rejections of claims 58 and 26. We find that the
differences between Arai and the subject matter of claim 57 are that Arai does
not disclose the step of "if said at least one input synchronous signal is not
received, generating separate reference horizontal and vertical synchronous
signals" and, so, does not disclose the step of "outputting the separate
reference horizontal and vertical synchronous signals or the separated
horizontal and vertical synchronous signals." For simplicity, we assume that
claim 57 requires generating reference horizontal and vertical synchronous
signals if no input horizontal and vertical synchronous signals are received,
although the "one input synchronous signal" language is broad enough to read
on not receiving only one of the vertical or horizontal synchronous signals.
Yamagishi provides a general teaching of supplying a replacement
"reference" synchronizing signal (INT. Sync) when a selected synchronizing
signal (Input Sync or EXT. Sync) is detected as missing for the advantage of
allowing subsequent circuit stages to continue to operate. One of ordinary
