An appeals court that specializes in patent lawsuits vacated a Tivo win in a patent battle with Echostar on Friday, sending Tivo shares down more than 38 percent.
The U.S. Court of Appeals for the Federal Circuit said that the entire court would participate in an en banc hearing to reconsider its March 4 decision in the case.
On March 4, the Federal Circuit had affirmed its contempt finding against Echostar and Dish in their long-running patent fight with Tivo, which makes digital video recorders.
Tivo's shares fell 38.1 percent to $10.76 in morning trading.
