said a U.S. District Court granted Cross Medical, a unit of
, an injunction against the company covering products that were found to infringe a Cross patent.
The patent relates to multiaxial screws used in spinal fusion surgery.
The rulings were in a case involving Cross Medical and Medtronic Sofamor Danek. Medtronic said the injunction has been stayed for 90 days, taking effect on Aug. 22. However, Medtronic will ask the appeals court to extend the stay pending rulings on appeal.
Earlier rulings on the case are already on appeal with the Federal Circuit, and Medtronic will also appeal the latest rulings.
Medtronic said the court ruling involved one of five patents in dispute in the case. On April 8, the court ruled that Cross Medical's cervical plate products infringed two of Medtronic's patents and that certain claims in two of Cross Medical's other patents were invalid. Medtronic said it plans to seek damages for the infringement.
Shares of Medtronic rose 22 cents to $53, and Biomet slipped 5 cents to $38.76.
