the logical channel structure seen by the aware applications and
the physical communications network (col. 5, lines 47-55). This
allows video channels, voice channels and other data channels to
be sensibly established. Four types of channels are supported:
standard, merged, synchronous, and serialized (col. 6, lines 16
and 17).
From the disclosure of Aldred, we agree with the examiner
that the channels are software objects. However, we agree with
appellants that the channels are dedicated mechanisms for
applications to communicate in a synchronous fashion. We find no
teaching or suggestion that Aldred is directed to a publish-
subscribe system. Nor do we find any teaching or suggestion in
Aldred that a channel may subscribe to another channel.
We are not persuaded by the examiner's assertion (answer,
page 6) that means for accepting publishers and subscribers can
be other channels is disclosed by Aldred (col. 13, lines 22-33)
and by Ravindran (page 1368, column 2). We find that the portion
of Aldred relied upon by the examiner refers to reallocating
bandwidth across channels. However, we find no teaching or
suggestion as to how this reallocation of resources teaches or
suggests channel objects including means for accepting publishers
and subscribers which are channel objects; i.e., channels
