He is also an adjunct professor at Columbia Law School, where he teaches a seminar on Supreme Court advocacy. Mr. Lefkowitz has served as lead trial and appellate counsel in a wide variety of substantive areas, including shareholder disputes, antitrust, product liability, litigation against the FDA and False Claims Act matters. He has also conducted numerous internal investigations for public companies and audit committees.
In its 2013 release of “The 100 Most Influential Lawyers in America,” The National Law Journal describes Mr. Lefkowitz as “a leading voice on school choice issues” and “a no-nonsense appellate and antitrust lawyer for an array of blue-chip clients.” The Legal 500 U.S. noted that Mr. Lefkowitz “provides a depth of understanding and influence in some of the highest courts of our country,” and in Chambers USA, America’s Leading Lawyers for Business, clients say, “‘Jay is brilliant; there is no other way to put it.’” Mr. Lefkowitzwas also named a Law360 “MVP of the Year” in 2011 for his Appellate practice, and in 2012, 2013, 2014 and 2015 for his Life Sciences work.

His victory in Mutual v. Bartlett in 2013, overturned a $21 million verdict on behalf of Sun Pharmaceuticals, and extended the Mensing ruling to cover design defect claims.
