The Court agrees with Comcast that no reasonable finder of fact could conclude that the Comcast Remote Tune system infringes the '907 patents. There is no ambiguity in the Court's prior claim construction, which included the limitation "without the use of a set-top box for remote control of the video-on-demand system" in the preamble of all of the asserted claims of the '907 patents. The set-top box cannot be involved in remote control of the VOD system, at any step, prior to the VOD system sending video to the television. If the set-top box is involved, the limitation of the preamble is not met and there is no infringement.
