TiVo popped 7.9% in early trading after it prevailed late Thursday in a Texas court ruling that involves its DVR patent infringement suit against AT&T — even though the ruling curiously didn’t say anything about the other part of the company’s suit, against Verizon. You’ll hurt your head if you try to sort through the mostly technical issues underlying U.S. District Court Judge David Folsom’s decision about how he’ll deal with the patent claims. But the upshot is that “AT&T will see a high chance of losing and so will likely enter into a favorable settlement with TiVo,” Lazard Capital Markets analyst Barton Crockett says this morning. David Miller of Caris & Co isn’t so sure: He expects AT&T to go to trial beginning in January. He also decided not to raise his estimates for TiVo because it’s  “somewhat confusing” that the judge didn’t include Verizon. ”The majority of the Street was under the impression that both cases were being heard in tandem,” he says.
