circuit 210 for the video signal. (Fig. 2; 3:51-56.)
H Applicants argue that Takabayashi and Ueno are directed to

7 USPQ2d 1500, 1502 (Fed. Cir. 1988). Ueno shows a Caller
ID/Call Waiting arrangement in a very complex
telecommunications system. The problem Ueno solves is not
unique to TV phones. Takabayashi shows a simple and
inexpensive Caller ID system using existing televisions.
One seeking to implement a low-cost version of Ueno's
invention would be naturally motivated to apply
Takabayashi's technology to the problem.
I Ueno provides the additional elements of claims 2 and 9.
Ueno teaches a communication path between two callers that

the communication path between the first two callers is
