TiVo has accused its competitors of manufacturing and distributing DVR units that make use of TiVo's patented "Time Warp" technology, which allows users to pause, fast forward and rewind live TV. Dish has admitted knowledge to TiVo's patent from the get-go, but has argued that its original technology is a Time Warp workaround. In their appeal, Dish will focus on a preliminary rejection of Time Warp's patent.
TiVo is also seeking damages from AT&T and Verizon for patent infringement. According to TiVo CEO Tom Rogers, the company "will continue to pursue enforcement where necessary" to prevent the unpermitted use of its technology.
