As part of that agreement, Vonage agreed to license VoIP patents from Sprint, including more than 100 patents covering technology for connecting calls from a traditional phone network to an IP network.Vonage is also in the process of resolving a patent infringement dispute with Verizon. Earlier this year, a court found&#160;Vonage infringed on Verizon patents&#160;and ordered an injunction that could have prevented Vonage from signing up new customers.&#160;Vonage won an injunction staying the order&#160;and is appealing the original infringement ruling.

(InfoWorld) - A federal court ruled on Tuesday that struggling VoIP provider Vonage infringed on patents owned by Sprint Nextel. Jurors in the U.S. District Court in Kansas found that Vonage willfully infringed on Sprint's patents as part of its VoIP service, Vonage said. The jury awarded Sprint $69.5 million in damages, which amounts to 5 percent of Vonage's revenue during the infringing period. Vonage plans to initially ask the court to set aside the verdict, but if that fails, the company will appeal the decision. In the meantime, Vonage will also develop workarounds that don't require Sprint's patents, it said. This is the second legal blow to Vonage this year. A court found earlier this year thatÂ Vonage infringed on Verizon patents. That case came with an injunction that would have prevented Vonage from signing up new customers.Â Vonage won a stay of that injunctionÂ and is appealing the original infringement ruling. Although it's clearly bad news for Vonage to have two patent infringement rulings against it this year, the appeals could change everything, said Seth Ostrow, a partner specializing in patents in Dreier LLP. "Often there are mistakes made during various stages of a case that form the basis for a successful appeal, and that, coupled with the statistics, gives reason to think that Vonage has a significant chance of getting this changed," he said. Statistics show that patent cases often get changed on appeal, he said. In August, Vonage said it had nearly completed rolling out workarounds for two of the three patents claimed by Verizon. Still, the Verizon case alone appears to have slowed growth for the company, the largest independent VoIP provider. In its second quarter this year, Vonage added 57,000 customer lines, compared with 256,000 in the same quarter in the previous year. Vonage has said that Verizon pursued the lawsuit in an effort to eliminate a competitor. Vonage stock opened the day at $1.99 and closed at $1.20, a 33 percent drop.
