Vonage is the darling of network neutrality advocates. Using Vonage, millions of people have canceled their telephone service in favor of an IP-phone that connects through the Internet.
Last month, a jury determined that Vonage infringed three Verizon patents. (6,282,574, 6,104,711, 6,359,880). These patents all relate to various aspects of Internet telephony.
This is not a "troll" case -- By definition, patent trolls are only looking for a payment in exchange for a patent license. Here, it is fairly clear that Verizon hopes that its patents will cause Vonage to close its doors. Thus, Verizon requested and was granted a permanent injunction.
