Sean Gallagher is an accomplished trial lawyer with experience across a broad range of complex commercial litigation matters. Most of Sean’s representations have been for major U.S. and international companies in cases involving intellectual property (including patent infringement and Lanham Act claims), trade secret misappropriation, product liability, accountant liability, toxic tort, and breach of contract. Notably, Sean served as lead trial counsel for Ethicon/Johnson & Johnson in a lawsuit claiming that pelvic mesh medical devices made by a J&J subsidiary caused personal injuries. The three-week jury-trial came to a complete defense verdict in the Philadelphia court of common pleas. Sean achieved a notable victory in an environmental tort case alleging more than $1 billion in alleged personal injury and property damage arising from a claim of a “cancer cluster” near the facility of Pratt & Whitney, an aerospace manufacturer facing the lawsuit. The case went on to summary judgment for the personal injury cases. Sean has also worked on a variety of other matters ranging from Gore v. Bush, where Sean was part of the Bartlit Beck team that represented President Bush at the trial court level in Newsome v. McCabe, where Sean helped obtain compensation for a man wrongfully convicted of murder.
