"My clients are entitled to a level playing field in the marketplace and deserve aggressive legal representation that is singularly focused on their business objectives."



Doug is Barclay Damon’s Intellectual Property Litigation Practice Area co-chair and co-leader of the Medical Devices and Communications & Networking Technology Teams. An experienced trial lawyer, he aggressively protects US manufacturers in the telecommunications and health care industries against the significant harm that results from the infringement of intellectual property rights, especially patent rights. He also defends US companies in these industries against competitor attempts to unfairly use patent litigation to hinder lawful competition.

Doug’s clients are located across the nation, and he routinely represents them in courts and administrative agencies that include the International Trademark Commission and the Patent Trial and Appeal Board in places such as Delaware, Texas, Illinois, Arizona, Arkansas, California, Minnesota, New York, Washington DC, and Wisconsin.

Doug actively works with his clients in alternative-fee arrangements to make intellectual property litigation costs more affordable and predictable.

In addition to his practice, Doug serves as the chair of Barclay Damon's AI Ad Hoc Committee.
