(TiVo, Dish and Echostar story updated with CreditSights commentary, JP Morgan upgrade and stock price movements.)NEW YORK ( TheStreet) -- TiVo ( TIVO) stock exploded on Thursday, after a federal appeals court affirmed a district court ruling against Dish Network ( DISH) and EchoStar ( SATS) for continuing to infringe upon TiVo's DVR patents. TiVo is expected to be paid about $300 million in rewards. TiVo stock skyrocketed 52% to $15.50 in midday trading Thursday, before settling the day at $16.50, up 61.9%. The stock has already risen 6.2% to $17.60 in pre-market trading. EchoStar on the other hand was down 0.3% at $19.80 Thursday, and settled the day 0.2% higher at $19.80. Dish also fell during the day, down 3.5% to $21. The stock ended the trading session down 5.2% at $20.60. Dish has added 2% at $21 in pre-market trading. Credit research firm CreditSights says that DISH Network has most of the financial exposure to the DVRs in question, even though Echostar makes the DVRs. DISH Network indemnifies Echostar on all but $5 million of court-awarded TiVo damages, according to the research firm. "The appeals court decision could back DISH Network into seeking a negotiated settlement of dispute, which we think would require a per-DVR payment to TiVo as a licensing fee," CreditSights notes. -- Reported by Andrea Tse in New York Follow TheStreet.com on Twitter and become a fan on Facebook.
