Vonage Sued Again, This Time by AT&T
The Internet phone company Vonage disclosed over the weekend that it had been sued, yet again, by a telecom giant for infringing patents, the Wall Street Journal reported. This time, AT&T says that Vonage is violating a patent which allows users to access an Internet phone system through a standard phone.
The suit was actually filed last Wednesday, but Vonage did not disclose it until issuing a regulatory filing late Friday.
Verizon’s suit against Vonage, which Vonage lost but is now appealing, led to a judge ruling that Vonage can no longer use certain technologies. Earlier this month, Vonage settled another suit, by Sprint, by agreeing to license over 100 Sprint patents for $80 million.
