Vonage Barred From Using Verizon VoIP Patents

thefiremonk writes "Bloomberg reports that U.S. District Judge Claude Hilton has issued a permanent injunction against Vonage. The goal: to stop allowing customers to make calls to standard phone lines. 'U.S. District Judge Claude Hilton approved Verizon's request for a block today in Alexandria, Virginia. Hilton said he won't sign the order before a hearing in two weeks on Vonage's request for a stay. A jury found March 8 that Vonage infringed three patents and should pay Verizon $58 million.' Does this spell doom for the already troubled Vonage? "

Yep.

If the order isn't stayed pending appeal, Vonage is dead; revenue drops to zero nearly overnight. So are all other independent VoIP providers, when Verizon gets around to crushing them.

A concrete manifestation of a patent system out of control.

Vonage's official response

One interesting tidbit:

"We are confident Vonage customers will not experience service interruptions or other changes as a result of this litigation," said Mike Snyder, Vonage's chief executive officer.
.
.
"Our appeal centers on erroneous patent claim construction, and we remain confident that Vonage has not infringed on any of Verizon's patents - a position we will continue to vigorously assert in federal appeals court," said Sharon O'Leary, Vonage's executive vice president, chief legal officer and secretary. "Vonage relied on open-standard, off-the-shelf technology when developing its service. In fact, evidence introduced in court failed to prove that Vonage relied on Verizon's VoIP technology, and instead showed that in 2003 Verizon began exploring ways to copy Vonage's technology," she added.

Re:What's the infringement?

Here's the original 7 patents... #6,430,275, #6,137,869, #6,104,711, #6,282,574, #6,128,304, #6,298,062, and #6,359,880.

It sounds like #6,430,275 (tiff, pdf, text/png) is the one that's the VOIP/POTS bit.

Re:Is the injunction legal?

[cdrudge]

There are many technical details why I think the injunction was granted but a stay will also be issued. You point out one very good one just because millions currently use VoIP. There also would be catastrophic damage done to Vonage if the stay was granted but minimal damage to Verizon (and what damage could be recouped) if the stay was granted but later lifted.

If it's 6,430,275, I personally developed the same class of product (PSTN/VoIP gateway with prepaid charging and authentication) in 98/99. We had been doing the same with ISUP and AIN variants even earlier.

It should appear obvious to any telecom's protocol engineer that this is possible. It is even encouraged by the protocols.

For example, INAP (ITU version of AIN in the patent), uses the same call model as ISUP, the circuit control protocol. ISUP and H.323 are both Q.931 protocols, therefore they also share the same call model. That makes it obvious (it was to us), that H.323 can be easily made to trigger an INAP call model. Obviously, the benefit is that this ensures that the applications can run unchanged on both the PSTN and the VoIP networks.

And H.323 has been around for a lot longer than this patent.

Once you understand that H.323 and ISUP are Q.931 variants, you see that all the work done to trigger IN applications on the various country and network ISUP variants is also prior art.
