Bill Zapf brings to KaiserDillon a strong litigation background and an analytical perspective developed from his years working at global law firms focusing on complex litigation and regulatory matters. He has an unusual depth and range of experience solving complex problems in cases involving highly challenging factual and technical issues.

Bill’s experience covers all aspects of complex litigation, from pre-suit due diligence through trial and post-trial proceedings. Before joining KaiserDillon, he handled highly technical patent cases and other complex matters for over nine years at Covington & Burling LLP, developing a particular expertise in damages and other financial and economic issues. He has represented a broad array of clients, from individuals to global consumer electronics makers and pharmaceutical companies.

Throughout his career, Bill has also devoted much energy to his pro bono practice, representing individuals facing criminal charges and civil claims in Montgomery County and Prince George’s County Circuit Courts in Maryland. It was this desire to help individuals during the most trying, stressful events of their lives that led Bill to join KaiserDillon’s criminal defense practice.

Before starting his law career, Bill attended law school at night while working full-time as an international economist for an AmLaw 100 firm. There, he led an in-house team of specialists providing economic and financial analysis to help international trade clients navigate complex federal trade regulations to avoid being locked out of the U.S. market.

Bill is admitted to practice in Maryland and the District of Columbia, the U.S. District Court for the District of Maryland, the U.S. District Court for the Northern District of Illinois, and the U.S. Court of Appeals for the Fourth Circuit.
