RADVISION Awarded Patent for Video Conferencing via Instant Messaging

Monday, February 22, 2010

RADVISION’s Patent Provides for Initiation and Support of Video Conferencing Using Instant Messaging

Tel Aviv, Israel -- RADVISION® Ltd. (Nasdaq: RVSN), a leading provider of video network infrastructure and developer tools for unified visual communications over IP, 3G, and emerging next-generation IMS networks, today announced that RADVISION has been granted a U.S. patent, numbered 7,631,039, for initiation and support of video conferencing using instant messaging (IM). In accordance with the patent, popular instant messaging services and applications can be used to automatically initiate video conferences providing a significant convenience to business and personal users.

Instant messaging is a very popular presence and text chat utility on networks today used by consumers and business users alike. The presence information supplied by instant messaging applications has become one of the primary means to initiate text, voice and video communications between users working on computers. Instant messaging is an ideal mechanism to launch audio and video conferences as users only need to know the names of those to whom they wish to communicate and not complex IP addresses or lengthy number strings; nor do users need to know which device the other parties prefer to use for their multimedia communications.

The patent granted to RADVISION covers the initiation and support of video conferencing using instant messaging. This combines the convenience of instant messaging with video conferencing, allowing a user to initiate a video conference from an IM directory or from within an IM session. In accordance with the patent, a video conference is initiated between participants in response to an instant message sent between two or more clients. The IM session includes information on the electronic addresses of the requested conference participants. The participants can then join the conference by any of several possible communication modes. For example, they may join a conference with a desktop computer or a dedicated high definition video conferencing room system using standard protocols such as SIP or H.323.

"RADVISION has always prided itself on its ability to anticipate major trends in real-time communications and foresee value in technologies that will ultimately benefit customers. This has led to the development or acquisition of some of the industry’s most innovative solutions making visual communications easy to use," said Roberto Giamagli, General Manager, Networking Business Unit of RADVISION. "The basis for this IM patent was one of the assets acquired as part of the acquisition of certain First Virtual Communications assets nearly five years ago and is an example of the innovative thinking RADVISION strives for. Similarly, we believe that intellectual property obtained through the recent acquisition of certain Aethra assets will also serve RADVISION for many years going forward."
