John A. McCauley


John McCauley focuses primarily on matters involving issues of science and technology. He handles litigation involving the design, manufacture, and marketing of prescription drugs and medical devices, as well as consumer products and services. His representative clients, whom he has advised and defended in a broad variety of litigation matters, have included publicly-traded pharmaceutical and medical device companies; a U.S. automobile manufacturer; a company devoted to network-security software, firmware, and hardware; and a designer/builder of roller coasters and other large-scale amusement attractions. John has litigated product-liability claims, consumer-protection class actions, and business disputes in courts throughout the United States. He has litigated cases to judgment – via trial or dispositive motion – in California, Florida, Maryland, Minnesota, Missouri, New Jersey, New York, Ohio, Oregon, Pennsylvania, Virginia and Washington, DC. He has briefed and argued cases in appellate courts in Maryland, Minnesota, New Jersey, New York, Oregon, and Pennsylvania.

Significant Matters

As counsel for a publicly-traded hospital products company, John has coordinated that company's successful nationwide defense in two mass-tort litigation matters involving prescription drugs. John has served with the team of lawyers defending a medical-device company in mass-tort litigation concerning an orthopedic prosthesis. He was the successful lead trial and appellate counsel in a case on warranty law that went to Maryland’s highest court. He obtained a $1.1 million jury verdict including punitive damages in a case involving breach of restrictive covenants and successfully defended the verdict on appeal. He was lead lawyer in defeating a Fortune 500 company's multi-million-dollar fraud, trade secrets, and unfair-competition claims against a network-security company. He was lead lawyer in litigating a class-action lawsuit against a mortgage company, with related insurance coverage litigation, which resulted in a favorable class-wide settlement funded by the client's insurer.
