Motorola Sues TiVo Over "Time Warp" Patents

Motorola Mobility Holdings Inc. filed a lawsuit challenging TiVo Inc.'s "time warp" patents and claiming it owns the rights to digital-video recording technology that was invented first. The complaint in federal court in Texarkana, Texas, contends TiVo infringes patents and seeks a ruling that Motorola Mobility customer Verizon Communications Inc.'s set-top boxes don't use TiVo inventions.
