Appeal 2006-2328
Application 10/131,049
Of course, if Arai does not generate reference vertical synchronous
signals, it cannot meet the step of "outputting the separate reference . . .
vertical synchronous signals," but this issue is not separately argued.
Facts
The scope and content of Arai and the level of ordinary skill in the art
are discussed in connection with claim 58.
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 . . . vertical synchronous
signals" and, consequently, does not disclose "outputting the separate
reference . . . vertical synchronous signals."
Principles of law
The principles of law are discussed in connection with claim 58.
Rejection and arguments
The Examiner found that Arai's synchronizing signal processing
circuit 301 "generates reference" vertical and horizontal synchronizing signals
VD3 and HD3 from a Sync on G input when no synchronizing signals are
received on VS or C. Sync/HS inputs (Final Rejection at 5). This is a
different interpretation of Arai than used for claim 58. In the Advisory
Action, the Examiner apparently realized that Arai did not disclose generating
a "reference vertical" synchronous signal. As with claim 58, the Examiner
