Ethicon’s decision to use a Pennsylvania-based company to manufacture its pelvic mesh products is the reason why nearly 100 lawsuits against the mesh-maker should remain in the Keystone State, according to a new ruling shedding light on how judges in Philadelphia may interpret the U.S. Supreme Court’s high-profile pronouncement in Bristol-Myers Squibb v. Superior Court of California.

The opinion, which Philadelphia Court of Common Pleas Judge Arnold New issued May 18, comes out about six months after he denied the Johnson & Johnson subsidiary’s bid to have a significant portion of the pelvic mesh litigation removed from the First Judicial District for lack of jurisdiction.
