The madness of process patents

When patents are filed and companies sued over basic packet processing and telephone features then it is time to call a stop to the madness. Vonage are being sued for 57 million dollars for the following patent infringements.
U.S. Patent 6,282,574 covers packet translation and how a service provider would encode IP packets so they can be ported over to the PSTN. It details the way addresses are processed on the domain name server by providing a name server for translating textual domain names into telephone numbers. The patent also describes how to support “name-to-address processing” on a name server based on specific parameters such as time, party or terminal making the request.
U.S. Patent 6,104,711, which Bell Atlantic filed for in 1997, covers how a carrier can support Advanced Intelligent Network (AIN) features, typical in PSTN services for VoIP customers. These features include call waiting, caller ID and three-way calling. The patent maps out how the “enhanced Internet domain name server” allows the Internet to communicate with a separate AIN to support these features for VoIP customers.
The third patent — U.S. States Patent 6,359,880, which was applied for in 1999 — covers how public wireless and cordless Internet gateways communicate with the Internet. It falls under another business method patent that details a localized wireless gateway system.
The patent details how a local wireless gateway can be used to support VoIP calls. It describes how calls can be transferred from the Internet to a wireless gateway at a customer’s location to support the call on a Wi-Fi or other public domain wireless spectrum.
