FDA Alert on Hacking Vulnerability in Heart Defibrillators is Wake-Up Call: Lawyers

John Sullivan was quoted in Law360's recent article on the U.S. Food and Drug Administration's recent safety alert last week about the vulnerability to hacking of up to 750,000 implantable heart defibrillators.

John practices in the firm's Commercial Litigation Department and has nearly two decades of experience handling a wide variety of complex litigation. He defends companies in securities, corporate governance, antitrust, product liability, class action, mass tort, and other business litigation.

John regularly represents global companies in the life sciences, chemical, banking, venture capital, fund management, and real estate industries.  

In the area of financial litigation, John defends clients in state and federal courts in disputes involving contested takeovers, securities class actions, investigations by the SEC Division of Enforcement, contested mutual fund rights offerings, RICO claims, fraud claims in insurance company insolvency proceedings, and commercial real estate contract disputes. He often advises mutual funds and banks on litigation and regulatory issues.

John has also served on trial defense teams in some of the largest and most challenging products liability and mass tort litigation in the last decade. He has defended companies in coordinated proceedings involving claims of failure to warn, consumer fraud, manufacturer and design defect, and warranty and breach of contract.

A well-rounded commercial litigator, John has deep experience managing attorneys conducting case-specific discovery, defending witnesses, handling evidentiary and coordination hearings, negotiating with opponents, and deposing and defending expert witnesses. He has litigated constitutional and preemption issues, dealt with regulatory agencies and their regulations, and represented clients in appellate proceedings before state and federal appellate courts, including the United States Supreme Court.

Before joining Cozen O’Connor John was a partner Dechert LLP, and he started his career at Sullivan & Cromwell. For John's considerable success, he has been recognized by Benchmark Litigation as a “future star” in their 2009 and 2010 editions and an “innovative lawyer” by the Financial Times in 2011.

John is a frequent author and speaker at legal conferences, and he is often asked to comment on current litigation in the legal media. He is an author of the Class Action Defense Review, as well as the Drug & Device Law Blog, one of the most well-respected product liability litigation blogs.

John earned his law degree from Rutgers School of Law-Newark, where he was awarded the Order of the Coif and was a two-time Saul Tischler Scholar. He received his bachelor's degree from Rutgers University, New Brunswick.

8th Circ. Suggests More Mass Torts May Be Removable [Law360]

January 03, 2014

The Eighth Circuit recently upheld the removal to federal court of product liability claims filed by over 100 plaintiffs in state court in St. Louis. See Atwell v. Boston Scientific Corp., 2013 (8th Cir. Nov. 18, 2013). The decision illustrates how plaintiffs’ requests to coordinate multiple cases can sometimes sweep “mass tort” cases filed in state court right into federal court as a “mass action” under the Class Action Fairness Act of 2005. This is no small shift in a litigation, and so Atwell provides a helpful background on some of the characteristics of a plaintiff coordination proposal that can trigger such CAFA removal.
