Adding some extra tension to their already heated battle over broadband voice and TV customers in the NY Metro area, Verizon last year sued Cablevision for violating five DVR patents. As is usually the case in these suits, some of the patents involved were painfully vague, such as a patent for technology that "allows users to navigate available programs by channel, and through the selection of an anchor channel, by category." More than a year later, and a court has ruled in Cablevision's favor in four of the five patent claims. The fifth patent had already been invalidated in a Virginia court. "This is a significant victory for Cablevision," said Jim Maiella, a spokesman for Cablevision. "We are obviously very pleased, and will continue to defend ourselves vigorously as the process continues."
