Johnson & Johnson lost a $1 billion verdict on Thursday in a closely watched trial over a hip implant device made by its DePuy Orthopaedics Inc. division.

After less than a day of deliberations, a federal jury in Dallas awarded $1.04 billion to six plaintiffs after concluding that Johnson & Johnson misled them and their doctors about the safety of the Pinnacle hip implant. The lawsuits were combined in a trial that began on Oct. 3.
