Bowman and Brooke Logo

For more than 25 years, John has defended manufacturers in product liability litigation in trial and appellate courts involving a multitude of products ranging from ATVs and RVs to suction vibrasorbers. He has tried cases from Idaho to Indiana and defended clients in courtrooms from California to Connecticut, Minnesota to Florida. From single cases to mass tort litigation and class actions, he has defended it all. 

Although John has defended a variety of products, he has focused his practice principally on defending pharmaceutical, medical device and chemical manufacturers. Most recently, John has defended leading medical device and pharmaceutical manufacturers in mass tort litigation involving infusion pumps and acne medication. John's work has been at the forefront of the infusion pump litigation, including the first summary judgment and appeal for any pump manufacturer. More than 15 years ago, John began defending a leading manufacturer and marketer of institutional cleaning and sanitizing products against claims their products caused leukemia and other cancers, multiple chemical sensitivities, birth defects, and major organ diseases, and acute injuries and illnesses resulting from inhalation, dermal, ocular, and ingestion exposures.

Regardless of the type of case he is defending, John prides himself on attacking the scientific and technical basis for allegations against his clients. He has earned a reputation for developing and advancing Daubert challenges to opponents’ expert testimony, from deposition through motion briefing and hearing and appeal.  John has briefed and argued Daubert motions in such fields as chemistry, toxicology, orthopaedics, epidemiology, human factors, mechanical engineering, biomechanics, economics, materials science, obstetrics and veterinary medicine.
