  Biography

Mark S. Cheffo is Co-Chair of Quinn Emanuel’s Global Product Liability and Mass Torts Practice.  He represents defendants in products liability, insurance and mass torts litigation, serving as national coordinating and trial counsel both in large, complex matters and in individual cases. He has represented pharmaceutical and medical device manufacturers, designers of bioengineered agricultural products, and sellers of consumer and industrial products. He also has handled insurance sales practices cases and numerous toxic and environmental exposure suits.

Mr. Cheffo has been a member of several trial teams in high-profile pharmaceutical litigation, and actively manages all stages of pre-trial proceedings. He has taken and defended numerous expert and company witness depositions and has briefed and conducted numerous Daubert and Frye challenges. Mr. Cheffo has briefed and argued dispositive motions and appeals in state and federal courts throughout the country.

Mr. Cheffo secured a complete dismissal in multidistrict litigation on behalf of several pharmaceutical companies in connection with personal injury claims arising from the manufacture and distribution of generic prescription medications containing propoxyphene. He was named “Litigator of the Week” by The Am Law Litigation Daily for his role in the matter (March 8, 2012).  He successfully argued a motion to dismiss a consolidated nationwide consumer fraud class action complaint in an MDL,  and also argued the appeal in the Ninth Circuit, where the district court’s decision was affirmed. In addition, Mr. Cheffo has conducted many arbitrations and mediations dealing with a host of disputes.

Mr. Cheffo is active in local bar associations and is a frequent lecturer on products liability issues. In December 2010, he spoke at ACI’s 15th Annual Drug and Medical Device Conference (one of the largest conferences for the pharmaceutical industry) on the topic of “Negotiating and Managing Complex Settlements: Ethical and Practical Considerations.” He also is very involved in pro bono efforts. He obtained a judgment of more than $1.7 million for liability and legal fees on behalf of 11 restaurant workers in New York’s Chinatown. He also obtained a jury verdict in a defamation case and, while representing the city of New York in Bronx Supreme Court, obtained a directed verdict in a case brought by three plaintiffs who had been shot while in prison.
