Mr. Clayton has extensive trial and appellate experience in a wide range of litigation matters. Early in his career, he spent more than a year on trial in perhaps the largest product liability class action ever to proceed to a jury verdict. Other significant product liability matters he has been involved with include Fen-Phen, in which he and his co-counsel obtained a substantial settlement for a group of objecting health insurers, as well as lawsuits involving prescription drugs and cell phones. Mr. Clayton also represented numerous health insurers in antitrust lawsuits against a pharmaceutical company.

In the intellectual property area, Mr. Clayton has handled litigation involving software licensing and copyright infringement as well as patent suits relating to laser and manufacturing technologies.

Mr. Clayton has also represented a major Philadelphia daily newspaper and two cable television broadcasters in several lawsuits involving claims for defamation and invasion of privacy.

Mr. Clayton recently handled a successful appeal in which the Pennsylvania Superior Court overturned a $13 million trial verdict against a bank in a mortgage satisfaction case. In another recent case on behalf of a different bank, Mr. Clayton, together with Mr. Feldman, obtained an award of summary judgment that was featured as the front-page lead story in The Legal Intelligencer and subsequently affirmed by the Third Circuit. He and Mr. Bazelon recently obtained another award of summary judgment in the Philadelphia Court of Common Pleas on behalf of a major corporation in a business dispute in which the plaintiff alleged $20 million in damages for tortious interference. Mr. Clayton has handled many other commercial matters, a civil rights trial, and appeals to state and federal courts.

Mr. Clayton earned his B.A. and M.A. with honors from the University of Pennsylvania, and his law degree from Columbia Law School, where he was a Harlan Fiske Stone Scholar and served on the editorial board of a law journal.
