Net2Phone Sues Skype Over Patent

As the VOIP market continues to heat up, so does the litigation. Net2Phone sued Skype in U.S. District Court in New Jersey, alleging patent infringement. The suit centers around point to point IP technology, which allows for an exchange of IP addresses in order to establish a link between two devices. Skype uses the technology to make calls.

Skype is also the defendant in another patent suit filed in late May by the owners of the Morpheus network. In that suit, StreamCast Networks claimed Skype broke an agreement that gave it first right of sale to the FastTrack network protocol. The technology is the foundation of Skype's Internet calling, and was used for file sharing in Morpheus.
