Charles (Chuck) Marion primarily focuses his practice in the areas of complex business litigation, franchise litigation and counseling, intellectual property litigation (including patent and trademark infringement cases, claims for unfair competition and breach of non-compete and/or non-solicitation agreements, and trade secret disputes), and product liability matters. In addition, Chuck regularly advises and defends companies whose websites and mobile applications have been accused of violating the Americans with Disabilities Act ("ADA") and similar state and local statutes, and frequently writes and lectures on the subject.

In the franchise area, Chuck has, for many years, represented franchisors in several different industries (including the quick service restaurant, hospitality, and automotive parts and service industries) in a wide variety of legal matters, including litigating, arbitrating, and resolving disputes with their franchisees, enforcing trademarks and other intellectual property assets and rights, and counseling on ADA issues relating to their physical locations and online/digital activities (websites, mobile applications, ordering kiosks, etc.). Chuck also regularly writes and lectures on franchise law issues, currently co-chairs the Philadelphia Bar Association's Franchise Law Committee, and is an active participant of the American Bar Association's Forum on Franchising.

He is an experienced litigator who has tried numerous cases to verdict in various state and federal courts throughout the United States. He has also served as lead counsel in several domestic and international arbitrations, and regularly represents clients in mediations and other types of alternative dispute resolution.

Chuck understands the risk, uncertainty, disruption, and expense associated with litigation, and often counsels clients on steps they can take to reduce the risk of litigation or, if a lawsuit has been commenced, methods they can utilize and strategies they can implement to resolve the lawsuit at an earlier stage and on the best possible terms.
