Commercial Litigation

Pietragallo’s Commercial Litigation Group exists in the realm where business and industry intersect with the courthouse. The lawyers of our group enforce contractual rights, protect intellectual property, enjoin unlawful competition, defend product integrity, guard against governmental intrusions, protect corporate assets and eliminate unlawful use of trade secrets.

National in scope and reputation, the lawyers in this group have been honored by Chambers and Partners, and memberships in the American College of Trial Lawyers, the International Academy of Trial Lawyers, the American Board of Trial Lawyers and the Association of Defense Trial Attorneys, and have been listed in “The Best Lawyers in America,” including “Litigator of the Year” for Bet-The-Company Litigation.

But the right pedigree is incomplete without the appropriate courtroom experience. Our litigators have presented cases and taken verdicts in hundreds of courthouses across the country. Our success rate is the result of our industry. We employ state of the art litigation technology and strategies in combination with good old-fashioned hard work in the representation of our clients. The results and our clients speak for themselves.
