International Securities Exchange LLC, an all-electronic options trading market, opted out of a patent trial against Chicago Board Options Exchange Inc. on the day its lawyers were to deliver opening statements to a jury.
U.S. District Judge Joan H. Lefkow, who was presiding over the lawsuit in federal court in Chicago, issued a series of adverse pre-trial rulings that compelled ISE to “cease pursuit of the case,” it said in a statement today.
