The following is a post by Jeff Pulver, one of the cofounders of Vonage and of modern VoIP, who published a book, “The Internet Telephone Toolkit”, two months before the patents in question were issued: http://pulverblog.pulver.com/archives/006846.html
He clearly remembers having already developed the technology and along with other engineers contributing these ideas to the public domain. It seems to me Verizon clearly stole these ideas from the public domain.

You’re right about which patent is the most crucial, which I believe refers to RTP (Real Time Protocol) to PSTN (public switched network) translation. So if this patent is eventually upheld then anybody on a packet-switched network will not be able to contact anyone in a public-switched network. There are millions and millions of lines in the US that use VoIP so communication between these networks will still be possible. Furthermore, I don’t believe Vonage actually manages these rtp-pstn gateways (Cisco gateways) but the translations are made through companies like Level 3, XO, Focal, Telcove, etc. But somehow, Vonage is still liable.

thanks i was looking for the details too, glad to found them here. question: do you know how Verizon came to own these patents? that is was it the LEC that developed them or were they acquired through mergers or acquisition?

Very good information on here. Just my guess from some of the things I’ve read around the net, I believe the wireless patent refers to vonage’s WiFi UTStarcom F1000 phone. This phone wireless hotspots or your home or office wifi router instead of a regular voice adaptor.

I have also heard talk about it including the use of the Vonage V-Phone if used in conjunction with a laptop on a wifi connection. The V-Phone is small 256MB USB Key that includes the Vonage SoftPhone software and a headset you plug into the USB Keyfob. I believe this would be harder to prove the wifi patent, as it would be the laptop connected to the network instead of the phone itself.

Very nice job of assembling details and tying it together.
Thanks for taking the time.

Having invented a spectrum maniplated packet transmitter in 1974, subequently turned over at no cost to a government agency,
it appears to me that Verizon’s patents require re-examination. In particular, whoever files for re-examination should do some research concerning German and Japanese patents. In Germany, you want to research Siemens. Next, check France. If any of these countries published similar inventions, Verizon’s patents may be pre-empted and may not hold up on re-examination. Anyway, I hate patent troills, anyway. E-mail me at my username at any major service provider.

Very thank you for the post.

It looks like there was some kind of PC-to-Phone or Phone-PC-PC-Phone that was available before they applied for patent 6,430,275.
If that's the case, how can Verizon be granted for patent when other companies were using VoIP? I thought VoIP existed before 1999?
If VoIP existed before the patents, it should be invalid?
