Mark is a noted CLE lecturer, presenting to many groups including WSPLA, the IP Section Law Institute and the Inland Empire Intellectual Property Institute and has served as an Adjunct Professor in Intellectual Property Law.

Mark has aspired to Intellectual Property law since the age of 14 when he learned of the confluence of law and engineering in the practice of patent law. To that end, he has sought experiences, such as an internship under the famed head of the patent department at 3M, Harold Hughesdon.

After receiving degrees in Mathematics and Physics from the then-College of St. Thomas in St. Paul, Minnesota and his Juris Doctorate from the University of Minnesota, Mark sought experience in litigation. On advice from a mentor, Mark was commissioned as a Navy Judge Advocate and tasked with trying cases before courts martial in diverse and interesting venues such as the wardroom of the USS Enterprise off of Qatar, the American Embassy in Manila, Treasure Island in San Francisco Bay and at the Naval Amphibious Base, Coronado.

Since completing his Navy tenure, Mark has practiced for thirty-five years in Seattle. Mark has demonstrated competence in both the procurement of patent, trademark, and copyright registration and in the litigation of both those rights and asserting ownership of trade secrets.

Mark is an adjunct Professor of Law at Gonzaga University where he also serves on its Board of Advisors. The Washington State Bar Association has noted Mark’s talent as a teacher of other attorneys by awarding him as the “Best of the Best” in three consecutive years.
