Seems like a patent troll…
All three of the Touchstream patents in question are titled "Play control of content on a display device" and detail "a system for presenting and controlling content on a display device" that uses "a network, a server system coupled to the network and comprising one or more servers, a display device coupled to the network and having a display, and a personal computing device operable to transmit a first message according to a specified format over the network to the server system."
Play control of content on a device. So…remotes violate this patent? Cmon.
