AT&T uses 1996 patent to go after Vonage

AP reports: Vonage said AT&T filed the lawsuit Wednesday [Oct. 17] in U.S. District Court in Madison, Wis. It said it has been in discussions with AT&T to resolve the dispute but can't guarantee the case won't go to trial.

The single patent in question, filed in 1996, appears to broadly describe the idea of routing telephone calls over data networks like the Internet. The listed inventor is Alexander Fraser, AT&T's former chief scientist.
