Item 8.01 Other Events

On August 17, 2012, Warsaw Orthopedic, Inc., Medtronic Sofamor Danek U.S.A., Inc. and other entities related to Medtronic, Inc. (collectively "Medtronic") asserted additional patent claims in its ongoing dispute with NuVasive, Inc. ("NuVasive"). Specifically, the complaint filed by Medtronic in the United States District Court for the Northern District of Indiana alleges that various NuVasive spinal implants (including its CoRoent® XL family of spinal implants) infringe U.S. Patent No. 8,021,430, and that NuVasive's Osteocel® Plus bone graft product infringes U.S. Patent No. 5,676,146 C2. These additional patents expire in the next 3-4 years.

NuVasive strongly denies infringing any valid claims of these additional patents and intends to defend the lawsuit vigorously. NuVasive is assessing all offensive and defensive measures available to it, including the assertion of counterclaims and the use of administrative reexamination procedures available through the U.S. Patent and Trademark Office.
