Introduction

Marten helps clients advance their goals in complex litigation through nuanced analysis and forceful advocacy.

Marten King has developed a diverse litigation practice representing many of the largest and most innovative companies in the country. He has handled contractual disputes, antitrust cases, environmental lawsuits, and international arbitrations. He has experience across all phases of litigation, from taking depositions and writing appellate briefs to examining witnesses before a jury. 

Through clear-eyed analysis, Marten crafts powerful arguments while helping clients accurately assess their positions. He takes the same analytical approach to case management and discovery, looking for ways to efficiently litigate cases by mastering frontier technologies and picking the right fights—the ones that matter to the outcome and a client’s bottom line. 

Marten is committed to pro bono work, as he understands the difference that a competent lawyer can make to those without the means to hire one. Most recently, he represented a Washington mother who was trying to stop her young daughter from being sent to Saudi Arabia. Marten’s advocacy in the Washington Court of Appeals helped keep their family together. 

Marten honed his oral advocacy skills by competing in parliamentary debate in college. He was the top individual speaker in the nation during his senior year.
