After the preliminary injunction was denied, Össur petitioned the U.S. Patent and Trademark Office (the “Patent Office”) to institute an inter partes review of 19 claims of the ‘726 Patent. Össur’s petition asserted that certain claims of the ‘726 Patent are invalid because they would have been obvious to a person of ordinary skill in the art. Össur’s petition did not seek review of two of the four independent claims at issue in the case. Össur’s moved to stay the district court case pending the inter partes review.
