Medical Device Patent Case: Jury Rules Medtronic Willfully Infringed TAVI Heart Valve Patent from Edwards Lifesciences

The patent involved in Wednesday’s ruling is known as the Cribier patent, which also was the focus of a lawsuit in Europe that Medtronic won. Medtronic had appealed an earlier decision on the “Anderson” patent through the U.S. Supreme Court, which declined to hear it. Medtronic paid Edwards $84 million in initial damages last year in a case that’s still pending. In November, Medtronic resumed selling CoreValve in Germany after a court overturned an earlier ruling that Medtronic infringed on Edwards’ “Spenser” patent. A higher court said it would not enforce that ruling, after the European Patent Office said Edwards’ patent is not valid.

The lawsuit over the Cribier patent was filed in federal court in California in June 2011 and transferred the following year to Wilmington, Del.

Medtronic officials say the company plans to appeal the Delaware jury’s decision. However, the jury found that Medtronic’s infringement was “willful.” If that finding stands, Edwards could be entitled to damages up to three times the jury’s award, plus attorneys’ fees.

“While we are disappointed in the jury’s verdict, we continue to believe that this decision will be overturned on appeal,” said Neil Ayotte, vice president and acting general counsel at Medtronic. “Medtronic has prevailed against Edwards in several legal actions related to a European counterpart to this patent and others, and believes the Federal Circuit Court of Appeals will find no merit to Edward’s infringement claim. Today’s jury verdict does not impose an injunction, and Medtronic will oppose any requests for an injunction by Edwards.”

According to a statement on the company’s website, Edwards plans to seek an injunction to prohibit Medtronic from selling Core¬Valve.

New York, N.Y.-based Leerink Swann analyst Danielle Antalffy said in a note to investors, however, that an injunction was “highly unlikely,” given that it was not part of the jury’s decision. Rather than injunctions, many U.S. patent cases involving medical devices are settled with payment of a royalty.

“Today’s ruling is a nice turn of events for Edwards, but don’t expect investors to ascribe significant value to the ruling given that the appeals process can take time—we estimate 14-18 months,” Antalffy said. “We believe an injunction barring Medtronic from launching this year in the U.S. is highly unlikely and was not issued in today’s ruling; Medtronic actually won the European Cribier patent case; and the German Spenser patent case is fresh in investors’ minds, where Edwards’ injunction barring Medtronic from Germany was overturned in November.”

Aortic valve stenosis is a deadly narrowing of the aortic valve that obstructs blood flow from the heart. Half of patients with aortic valve stenosis die within two years of diagnosis. About 300,000 patients worldwide are diagnosed with aortic stenosis each year. Some patients are considered too sick to endure the trauma of having their chests open, and TAVI allows doctors to insert a new valve by inserting a catheter through an artery in the leg or through an incision in the upper body. Patients can be home from the hospital within a couple of days, instead of weeks after the procedure.

    A U.S. District Judge defends a ban on Medtronic’s newly approved CoreValve transcatheter aortic valve implantation system, saying the company willfully ignored the law in bringing the device to the U.S. after it was found to infringe on a patent held by Edwards Lifesciences.

    Judge: Medtronic thumbed nose at the law in bringing CoreValve to U.S.
    U.S. District Judge Gregory Sleet chided Medtronic (NYSE:MDT) this week after issuing a preliminary ban on the medtech titan’s CoreValve transcatheter aortic valve implantation system.

    Judge Sleet wrote that Medtronic willfully sidestepped the law in bringing the device to market. He ruled late last week in favor of Edwards Lifesciences (NYSE:EW), granting an injunction to limit Medtronic from selling the devices in the U.S.

    The ruling was a major victory for Edwards, coming after some 6 years of legal sparring, but it’s certainly not the end of the battle. Medtronic’s lawyers convinced Judge Sleet to grant a 7-day stay on the injunction as the company promptly pursues an appeal.

    Edwards initially filed the infringement claim in 2008 against CoreValve, then an independent entity. Medtronic acquired the company in 2009 and a federal jury ruled in 2010 that the CoreValve device willfully infringed on Edwards’ “Andersen” (‘552) patent.
