Cox Communications is facing a patent infringement lawsuit by Verizon which claims that the cable company has violated eight of their VoIP technology patents. Four of those patents are the same ones which were being used by Vonage until Verizon won $120 million in a similar lawsuit against the company. Some fear that the win could have set a trend for Verizon to continue going after other companies all throughout the year. The industry is unsure as to why Cox is the sole focus of this particular lawsuit since the same technology is being used by other cable operators.
