LUCERO, Circuit Judge.
This case is before us for further consideration following receipt from the Oklahoma
After Dr. Brian Howard received a knee implant manufactured by Sulzer Orthopedics, Inc. ("Sulzer") that failed to bond properly, Howard and his wife filed suit against Sulzer alleging negligence per se. Howard v. Zimmer, 711 F.3d 1148, 1149-50 (10th Cir.2012). Following the completion of earlier consolidated litigation, the district court dismissed the Howards' negligence per se claim, predicting that it would not be cognizable under Oklahoma state law. Id. at 1151. On July 3, 2012, we stayed the Howards' appeal pending resolution of a question of state law certified to the Oklahoma Supreme Court. Id. at 1153. That question has been answered, and we now reverse the district court's grant of summary judgment and remand for further proceedings.
The relevant factual background and procedural history of this case is thoroughly presented in our prior order, id. at 1150-51, and need not be repeated here. After we resolved the only other issue on appeal, concerning implied preemption, we certified to the Oklahoma Supreme Court the following question:
Howard v. Zimmer, 299 P.3d 463, 464 (Okla.2013) (footnotes omitted).
This question has now been answered in the negative by the Oklahoma Supreme Court. It held that "Oklahoma law allows private individuals to maintain a parallel claim for negligence per se based on violation of a federal regulation whose enforcement lies with a governmental entity." Id. at 467. The court further concluded that "[t]he existence of a provision in federal law providing that all enforcement proceedings `shall be by and in the name of the United States' does not prohibit a state law claim for negligence per se based on violation of the federal regulation." Id. at 469. Noting that Howard does not claim he should be entitled to bring a private action under the FDCA, but rather brings a state claim based on duties that "parallel, rather than add to, federal requirements," id. at 470, the court determined that Howard's negligence per se claim should be allowed to proceed, id. at 473-74.
In light of this conclusive determination of state law, the district court's dismissal of the Howards' negligence per se claim cannot stand. We therefore
