Phone Wars
I see this case as a war between phone companies and Internet Companies. The more traditional phone companies want to deny any of these Interenet based phone companies from competing.
The Patents were issued in such a broad manner to prohibit all phone communication using and IP Address. However, I dont see them sueing AT&T or Siemens who both make and distribute VOIP Systems.
I dont see how you can get a patent so non specific and have it hold up in court. I did not think that Vonage is not the first company that has used an IP Address to send a communication from a phone. I would argue in this case that because so many big players are using VOIP devices that it has become an industry standard.
