A fairly obvious trade is presenting itself in shares of TiVo (TIVO). The company has been involved in patent infringement litigation with DISH Network (DISH) and Echostar (SATS) since 2004. At pretty much every step of the way, TiVo's claims have been upheld, including by the U.S. Patent Office this last October.

Currently, the U.S. Court of Appeals for the Federal Circuit is conducting an en banc review of an earlier decision, which upheld a lower court's ruling in TiVo's favor with regard to the infringement of company patents by DISH and Echostar. The CEO of TiVo has said that he expects the litigation to be resolved by February or March of 2011.

With its stock trading at less than 13 cents, you might think the debt-crippled Sirius XM Radio Inc. (NASDAQ: SIRI) would accept any takeover bid that would mean it could avoid bankruptcy.

Apparently, you'd be wrong. The Wall Street Journal reports (subscription required) that satellite mogul Charles Ergen made an unsolicited takeover bid late last year, but was rebuffed by the company and its board of directors. Ergen had reportedly proposed that one of his companies -- either Echostar Corp. (NASDAQ: SATS) or Dish Network Corp. (NASADAQ: DISH) -- provide the company with enough cash for it to avoid a bankruptcy filing.
