The U.S. Patent and Trademark Office (USPTO) recently sent the Notice of Allowance to Voip-Pal's wholly-owned subsidiary, Digifonica (International) Limited, on its patent application, "INTERCEPTING VOICE OVER IP COMMUNICATIONS AND OTHER DATA COMMUNICATIONS."

Digifonica’s patent-pending invention embraces the technology that terms the method to monitor VoIP calls right on the VoIP provider's equipment, independent of access methods (Wi-Fi, DSL, Cable, Wimax, etc.).

This technology is not bound to any administrative, political or geographical limitations, and any call originated from across the world – as long as it has an account with a VoIP provider – can be monitored.

Through this, the caller or recipient can change their Internet access from one Wi-Fi hot spot to another, and still be subject to Legal Intercept.

Even if the intercept target is using DID (Direct Inward Dial legacy PSTN number) for his/her VoIP phone, the call can still be monitored.

The patent application was filled in 2007 as a PCT (Patent Cooperation Treaty) application, which later succeeded in the International phase, then entered the National phase in many countries, including the U.S. This notice of allowance means that prosecution is closed for the Lawful patent application and it is allowed for issuance as a patent.

As per the current rules and regulation, the Lawful Intercept technology is expected to be legislated by many governments for all VoIP providers. To date, Digifonica has filed five patent applications, which were initially labeled as PCT (Patent Cooperation Treaty) and came through International phase, then entered National phases in many countries around the world – first in the U.S., Canada and Europe.

They all are in different stages of prosecution.

Voip-Pal.Com, through its wholly-owned subsidiary "Digifonica (International) Limited Gibraltar," is a technical specialist in the VoIP services market, which had revenue of $58 billion in 2011 and is experiencing tremendous growth.
