AT&T Imitates Sprint and Verizon by Suing Vonage

I'm thinking I might need to change my home phone provider in the not too distant future. Following up on the expensive litigation brought by Sprint and Verizon, Vonage now has to go to court to defend itself against AT&T for alleged patent infringement. It's too early to tell if AT&T's patents are along the lines of Verizon's "we own the Interweb" patent, but my bets are that the prior art defense would play well if Vonage actually has to stones to defend itself instead of rolling over. Then again, history has shown us that Vonage just wants to cough up its lunch money so that the bullies leave it alone.
