Kenneth F. Baum
“Kenneth Baum is a stand-out name in” “complex medical and scientific matters” with “strong trial advocacy skills to boot.” – The Legal 500
Ken – who holds law and medical degrees from Yale – brings a highly specialized set of skills to defending claims brought against drug and medical device manufacturers. Indeed, Ken is widely regarded by clients and his peers as one of the nation’s leading practitioners in the product liability arena. Clients reporting to The Legal 500 repeatedly single out Ken as a “very hardworking, very skilled trial lawyer,” a key practitioner in product liability and mass tort defense, and a “stand-out name” in complex medical and scientific matters.
With a unique ability to synthesize and convey complex scientific and medical issues, clients seek out Ken to serve on and lead national science and expert teams in numerous high-profile product liability litigations, including Baycol® (Bayer), hormone replacement therapy (Wyeth), Vioxx® (Merck), Sprint Fidelis® (Medtronic), Seroquel® (AstraZeneca), gadolinium contrast dye (Bayer), Fosamax® (Merck), and Mirena® (Bayer). Clients repeatedly turn to Ken to depose key retained expert and treating physician witnesses, and his depositions have led to dispositive Daubert rulings, withdrawal of opposing experts, and voluntary dismissals with prejudice. Ken also is a pillar of bellwether trial teams, crafting witness examinations and developing theories that have ultimately led to the dismissal of thousands of cases nationwide.
