SONICblue, TiVo Trade Suits
By Karen Brown -- Multichannel News, 2/5/2002 8:05:00 AM
The patent battle between digital-video-recorder rivals has escalated.
TiVo Inc. recently filed suit against SONICblue Inc., owner of the ReplayTV Inc. DVR line, charging that SONICblue violated its wide-ranging DVR 'Multimedia Timewarping System' patent.
The patent, awarded to TiVo last May, covers technology that lets users record one television show while playing another and the process for pausing live TV, fast-forwarding, rewinding, instant replays and slow motion.
The Jan. 23 action follows SONICblue's suit filed in December charging that San Jose, Calif.-based TiVo had violated its patent covering search and playback for TV shows.
That lawsuit sought an injunction barring TiVo from making products with the disputed technology, plus damages.
SONICblue, meanwhile, is expected to announce its fourth-quarter earnings Wednesday.
The company furthered its technology this week with a licensing deal to supply dual-deck VCR technology to Samsung Electronics Co. Ltd. The specific terms of the deal were not released.
