> Medtronic ($MDT) is asking a San Diego federal court to compel NuVasive to pay royalties on sales of spinal surgery products that infringed its patents, as well as $19.8 million in interest on a 2011 jury verdict. The request follows a $101 million verdict won by Medtronic. "Anything less would reward NuVasive's ongoing infringement and would encourage NuVasive to continue to infringe rather than to develop its own technology," Medtronic's lawyers said in the filing.
