You say "excellent" but I say that to say voip-pal did this just ain't so. It was digifonica & their engineers who created the patents. Voip-pal simply bought them (digifonica) with shares I think. And as the pr shows below, it was Smart & Biggar (patent attys) who did the patents for them, according to vp's own pr:
...........................
Digifonica (International) Limited ("Digifonica") was originally incorporated
as Digifonica International Inc. in 2004 and listed on the TSX stock
exchange (DIL-H). The company raised more than $15M of investments
into research and development of the most advanced VoIP technologies. It
employed approximately 20 developers, some of them being well-known in
VoIP industry, who built an integrated white-labelled VoIP system, which
can be deployed for new Internet Telephony providers in matter of minutes.
The goal was two-fold:
1. Provide scalable and the most cost-effective solution for partners,
when prices for Internet calls go down to zero
2. Comply with government regulations of Internet communications
against illegal activities
Soon after the first production-grade
system was released for partners, it
became clear that architectural solutions developed and operated by
Digifonica, were highly advanced in the industry and required protection.
Digifonica decided to dedicate sufficient resources, both human and
financial, to work with the top Canadian firm practising in intellectual
property - Smart & Biggar. That cooperation produced the results:
Digifonica filed overall 5 patent applications, starting from 2007 (see
"About Voip-Pal/Digifonica Patent Applicatons" below). The Patent
Applications were all filed initially as PCT (Patent Cooperation Treaty)
applications, came through International phase, then entered National
phases in many countries around the world, first of all in US Canada and
Europe. They all are in different stages of prosecution.
