A U.S. Supreme Court decision widely greeted by defense attorneys as a “game-changer” hasn't exactly dealt them a slam dunk in the courts.

Since the Supreme Court's decision in Bristol-Myers Squibb v. Superior Court of California, defendants have cited the June 19 ruling in attempting to remove cases across the country to federal court with the goal of dismissing them. But federal judges haven't come down in their favor in all cases. In fact, of the nearly 30 rulings that have come out so far, many have turned for the plaintiffs, though often on narrow procedural grounds.

That hasn't stopped lawyers on both sides from citing the new rulings to support their case.
