A federal judge in Pennsylvania has shaved off numerous tort and breach of warranty claims brought by plaintiffs over the birth control device Essure, finding that many of the plaintiffs’ claims were not brought within the statute of limitations.

In a recent 60-page opinion, U.S. District Judge John Padova of the Eastern District of Pennsylvania weighed the claims of a dozen women suing Bayer over the device and determined that many should be dismissed at the summary judgment phase because they were not brought within the allowable time frame.
