Patrick F. Sullivan

Patrick Sullivan is an associate in the firm’s Chicago office focusing his practice on complex litigation. He is an accomplished litigator with extensive experience in life sciences and commercial defense. He regularly litigates seven-figure cases through trial in jurisdictions across the country, handling every aspect of litigation from pleading through appeal.

Mr. Sullivan's life sciences litigation experience centers on the defense of medical professionals, drug and device manufacturers and entities - including hospitals, nursing homes and pharmacies - relative to allegations of professional negligence, misconduct and products liability. He recognizes that the cornerstone of a strong life sciences defense is guiding the jury towards the appreciation of the unique and challenging circumstances faced by professionals and manufacturers in the field. He works closely with clients to help them better explain the intricacies of their specialized practice areas and products at deposition and trial.

His commercial litigation practice focuses on both the plaintiff and defense sides of litigation including contract disputes, corporate derivative actions, intellectual property litigation, cyber risk and liability litigation and associated appellate work. Because commercial litigation is increasingly complex in this digitized world, Mr. Sullivan believes the best strategy for limiting risk is effective planning, review and oversight to maintain an informational edge and stay two-steps ahead of your opponent.

Prior to joining Segal McCambridge, Mr. Sullivan was a trial litigator for both the plaintiffs’ and defense bars. This experience gives him institutionalized knowledge of procedure and a unique perspective on litigation strategy - a perspective which he frequently shares through professional writing and presentations.

Mr. Sullivan graduated from the UIC John Marshall Law School and received his undergraduate degree in political science and economics from Bradley University. Outside of work, Mr. Sullivan spends his time with his wife, two children and energetic Labrador.
