Vonage Sues AT&T Over VOIP Product
Vonage Holdings Corp. has sued AT&T Corp. for trademark infringement, alleging that the name of AT&T's newly launched VOIP service is confusingly similar to its company and product name. In its lawsuit filed last week in U.S. District Court in New Jersey, Vonage alleges that AT&T is infringing on its name by launching a VOIP service named CallVantage. Vonage also is accusing AT&T of cyber squatting for having filed a series of domain names in February that it says are similar to those owned by Vonage. Those Web addresses include variations on "callvontage" in the .com, .net and .biz domains.
The lawsuit points to the growing stakes in the VOIP market as more providers enter the space. AT&T rolled out its residential CallVantage service at this week's Spring 2004 VON Conference & Expo in Santa Clara, Calif. It announced availability for New Jersey on Monday and launched the service Tuesday for parts of Texas.
