Patent MarketPlace: Voice over Internet Protocol (VoIP)/IP Telephony Patents for Sale

Secure VoIP Voice, IM, Video, SMS and P2P (Lesavich): U.S. Patent No. 7,852,831

VoIP (or Voice over Internet Protocol) is now a common, less expensive and more adaptable alternative to conventional telephone service. You can do more via VoIP (like send data and video) than you can do – or at least do easily – with a conventional landline telephone.

This patent covers the foundational concept behind securely sending voice calls as well as video, IM (instant messaging), SMS (short message service) and P2P (peer-to-peer) communications over the Internet and other communications networks such as a PSTN (public switched telephone network) to and from any network device, and do so while maintaining privacy, security and quality of service for the users on both ends. FXO (Foreign Exchange Office) and FXS (Foreign Exchange Solution) interfaces are included in the patent, making international VoIP calls possible! The invention covered by this patent enables a network device to function as an IP PBX (private branch exchange) or a private VoIP gateway, and to provide and control VoIP voice communications without using other public or private VoIP gateways or VoIP servers or devices. And VoIP hardware and software components are covered in this most comprehensive patent for both wired and wireless VoIP communications.

U.S. Patent No. 7,852,831 for "Method and system for providing private virtual secure Voice over Internet Protocol communications" is both robust and foundational. The patent has 15 Claims, a 2005 Priority Date, a Patent Term Adjustment of 1,387 days, and over 200 Forward Citations! It would be a strategic acquisition for any company providing VoIP services including VoIP voice and video calling services similar to Skype and Facetime.
