JumperCable writes "The Electronic Frontier Foundation is seeking to bust an overly broad patent by a company called Acceris. Acceris claims patents on processes that implement voice-over-Internet protocol (VoIP) using analog phones as endpoints. These patents cover telephone calls over the Internet. Specifically, the claims describe a system that connects two parties where the receiving party does not need to have a computer or an Internet connection, but the call is routed in part through the Internet or any other 'public computer network'. The calls must also be 'full duplex', meaning that both parties can listen and talk at the same time, like in an ordinary phone call. To bust these overly broad claims, we need 'prior art' — any publication, article, patent or other public writing that describes the same or similar ideas being implemented before September 20, 1995."
