He has been an invited speaker.  He spoke before the American Bar Association’s Section of Antitrust Law’s Spring Meeting in 2010 (on the subject of resale price maintenance), 2015 (on the subject of product “hopping” and FDA risk mitigation abuse), and 2018 (on the subject of reverse-payment patent settlement agreements).  He spoke at HarrisMartin’s Antitrust Pay-for-Delay Litigation Conference in 2014, 2015, and 2017 on the subject of reverse-payment patent settlement agreements.  He spoke in 2012 on the subject of the filed rate doctrine at the American Antitrust Institute.  He has also spoken at ABA “brown bag” lunches on the subject of product hopping cases (2015) and reverse-payment patent settlement agreements (2017).

Earlier in his career, Mr. Kohn defended products liability, toxic and mass tort cases on behalf of insureds and self-insureds at LaBrum & Doak (1992-1994) and prosecuted toxic tort and civil rights actions at Monheit, Monheit, Silverman & Fodera (1994-2000), where he first-chaired several complex and expert-intensive jury trials.  While at the Monheit firm, Mr. Kohn acted as co-liaison counsel for plaintiffs in the lead-based paint poisoning litigation program of the Court of Common Pleas of Philadelphia County, and served as class counsel in three civil rights class actions seeking injunctive relief on behalf of housing authority residents exposed to lead-based paint.  During that time he worked to convince the Pennsylvania Supreme Court that the so-called “pollution exclusion” contained in comprehensive general liability insurance policies did not extend to lead-based paint poisoning.  See Lititz Mut. Ins. Co. v. Steely, 567 Pa. 98, 785 A.2d 975 (Pa. 2001) (reversing id., 746 A.2d 607 (Pa. Super. Ct. 1999)); see also State Auto Ins. Cos. v. Summy, 234 F.3d 131 (3d Cir. 2000).  Working with the state legislature on behalf of his minor clients, Mr. Kohn also successfully advocated for an extension, to civil actions, of the “tender years” hearsay exception of the Pennsylvania Rules of Evidence, which until that time had been limited to criminal actions.

Mr. Kohn has regularly been chosen by his peers as a “SuperLawyer” since 2009.  He is a member of the bars of the Supreme Court of Pennsylvania, the United States Courts of Appeals for the Second, Third, Sixth, Ninth, and Federal Circuits, and the United States District Courts for the Eastern District of Pennsylvania and the Eastern District of Michigan.

He is a 1992 graduate of Temple University Law School (cum laude), and a 1989 graduate of the University of Pennsylvania (B.A., English).  He was  a member of Temple’s trial team and the Temple Law Review.

Mr. Kohn is active in his community.  He has served or is serving on the boards of Philadelphia’s Magic Gardens, Commonwealth Youthchoirs, Settlement Music School (Mary Louise Curtis branch), Philadelphia Boys and Girls Choirs, and Penn’s Mask & Wig Club.

He lives in Center City Philadelphia with his wife and their two sons.
