Maybe this is a good patent, but we can surely debate on this one. I mean that it's not nearly as broad as the statement makes it out to be. Cisco's main claim to innovation here is the dynamic access lists that affect routing of multicast traffic based on individual customers' subscriptions. That's pretty broad, but it's nowhere near a blanket patent on triple-play in general. To the extent that anyone has to worry about the patent, it's not Comcast or AT&T. It would be Nortel and Extreme and other network equipment vendors who are probably already looking at offering the same capabilities in future products.
