NEW YORK ( TheStreet) -- TiVo ( TIVO - Get Report) and EchoStar ( SATS - Get Report) will appear before Federal judges tomorrow to present oral arguments in their ongoing patent infringement battle. The companies have been engaged in a legal battle since 2004 when TiVo accused satellite TV provider EchoStar's Dish Network ( DISH - Get Report) system of violating its Time Warp patent. The Time Warp software allows users to record one television program while watching another. In April 2006, a Texas jury found that satellite EchoStar had infringed on TiVo's patent claims. TiVo was awarded $74 million in damages and EchoStar was ordered to disable all of its DVRs. TiVo said it was confident that it would win the legal battle. "Today's decision further validates our
intellectual property and brings us closer to ending EchoStar's ongoing infringement," TiVo said in an Oct. 6, 2010 release. "Moreover, we remain confident that the United States Court of Appeals for the Federal Circuit will uphold and enforce an injunction against EchoStar's ongoing willful infringement of the Time Warp patent." Per EchoStar's request, the Court of Appeals has agreed to hear case. The companies will present their oral arguments tomorrow, Nov. 9, before the full or "en banc," Federal Circuit judges. Last month, at the Goldman Sachs ( GS Communacopia conference in New York, TiVo's CEO Tom Rogers said he expected the lawsuit to conclude between February and March of next year. "We look at the Dish litigation as something we're going to win," Rogers said. -- Written by Theresa McCabe in Boston. >To contact the writer of this article, click here: Theresa McCabe. >To follow the writer on Twitter, go to @TheresaMcCabe. >To submit a news tip, send an email to: firstname.lastname@example.org.
