I just came across Andy Abramson’s post on Verizon’s VoIP patents which discusses the fact that 3COM may be one of the companies sitting on a VoIP patent eerily similar and earlier than one of the Verizon patents being used against Vonage. This reinforces my earlier post on the VoIP patent mess from today discussing how many companies have related patents that can potentially be used to overturn the patents Verizon is using to sue Vonage.
