and manipulated by all participants in the teleconference.
However, with the wide diversity of systems having different
computer capabilities, prior art systems have typically required
that the application provide support for all capabilities used
within the teleconference. This fact substantially complicates
teleconferencing applications, and makes expansion of
capabilities difficult or impossible. Thus, it would be
desirable to be able to relieve the application of the burden of
supporting all capabilities by providing accessories which
interface logically between the application and the base
teleconference component to provide additional and expandable
capabilities. See page 1 of Appellant’s specification.
Appellant solves this problem by providing a system and
method which provides capability expansion in a teleconferencing
environment. One or more accessories are invoked and arranged in
an accessory stack associated with an application. The accessory
