Appeal No. 95-1292
Application 07/911,471
previously noted, Ueno expressly teaches decoding a caller
information signal for the third caller.
Q As with the Takabayashi/Ueno low-cost Caller ID/Call Waiting
system, the Krisbergh/Ueno system would forward the Caller
ID information to Krisbergh's television while the third
caller is in Call Waiting mode. This meets the requirement
of claim 15. As previously noted, an artisan would
naturally use an NTSC signal in a system using a
conventional television. Thus, claim 16 presents no
patentable distinction.
R Since Krisbergh explicitly teaches displaying the caller's
telephone number, it satisfies, in combination with Ueno,
the requirement in claims 18 and 20 that the caller
information comprise a telephone number.
S Krisbergh does not teach a specific hold function. Although
the hold function is known in telephony, the cited
references do not provide a motive for implementing the hold
function. Thus, we cannot sustain this rejection under
section 103 of claims 4, 6, 7, 11, 13, and 14. Since
Griffith does not resolve this deficiency, we must also
reverse the rejection under section 103 of claims 5 and 12
in view of Krisbergh, Ueno, and Griffith.
