Stephanie Smiertka Riley focuses her practice on corporate, commercial, and intellectual property litigation in all Delaware Courts, especially the United States District Court for the District of Delaware, Delaware Court of Chancery, and Delaware Superior Court. Her experience in complex commercial litigation extends to business disputes, including misappropriation of trade secrets, breaches of contract, and tortious interference; consumer protection and RICO claims; constitutional law claims; and pharmaceutical and medical device multi-district litigations. Because of her vast array of experience, as Delaware lead or local counsel, Stephanie offers a unique perspective on litigation strategy in addition to her knowledge of Delaware practice and procedures. She has also served as Delaware counsel assisting outside counsel in intellectual property litigation. After law school, Stephanie served as judicial clerk for several Delaware state court judges, which laid the foundation for Stephanie’s familiarity with Delaware best practices.

In addition to litigating disputes, Stephanie advises companies and individuals on best practices to avoid litigation. From her experience in advising companies on whether to initiate or defend litigation, she is able to identify and prioritize a business’s big picture goals. She has also represented government entities in a variety of capacities, including advising and litigation.

Stephanie is involved in the Delaware community. She serves on the Board of Directors for the Delaware Children’s Museum. In addition to that role, she serves on the Development Committee for the Delaware Combined Campaign for Justice which provides life-changing legal services for Delawareans in need.
