Johnson & Johnson launched a new legal incursion against the authors of an expert report that plaintiffs’ lawyers have cited in lawsuits alleging its baby powder caused mesothelioma.

On Thursday, a Johnson & Johnson subsidiary filed a lawsuit against Dr. Theresa Emory, a pathologist at Peninsula Pathology Associates, and two other experts, Dr. John Maddox, also at Peninsula, and Dr. Richard Kradin, a pulmonologist and pathologist in New Hampshire.
