Appeal No. 95-1292
Application 07/911,471
the third caller's connection request onto one of the
original callers. Takabayashi teaches that caller
information may be either a telephone number or a name, both
of which are alphanumeric.
F The claims do not expressly limit the nature of the
telephone communication path or the nature of the
television. Although Applicants argue that Takabayashi uses
an integrated services digital network (ISDN) line
(incidently Ueno also uses an ISDN line) and that Ueno uses
a "special" television, we note that these are either within
the scope of the claims or, at least, structurally
equivalent. Moreover, Applicants provide no evidence that
Ueno's television is any different from a conventional
television.
G Applicants note that Takabayashi does not teach all of the
limitations of claims 1 and 8. (Paper 14 at 11.) We note,
however, that Takabayashi is applied in combination with
Ueno, which provides the stated missing elements.
Applicants also urge that Ueno does not teach detection and
decoding of the third caller's video image. We disagree.
Detection of incoming calls is inherent in any telephone
system. Detection of third-party callers is called Call
