The suit comes in the wake of a suit filed against Nortel by Vonage earlier this year that alleged Nortel violated three of Vonage's patents. Two of the patents involved in that suit -- numbers 4,782,485 and 5,018,136 -- concern multiplexed digital-packet telephone systems. The third patent -- No. 5,444,707 -- concerns packet-switching communications systems. Vonage acquired these three patents from Digital Packet Licensing in 2006.
