Mark A. Griffin has over 31 years of experience in antitrust litigation. As a member of Keller Rohrback’s nationally recognized Complex Litigation Group, Mark has litigated over 100 class action cases, including over 40 antitrust class action cases, to successful conclusions. Mark joined Keller Rohrback in 1988 after serving as a judicial law clerk for Magistrate Judge Philip K. Sweigert of the U.S. District Court for the Western District of Washington. He helped launch the firm’s antitrust practice with achievements including $49.5 million in settlements in the Specialty Steel Pipe Antitrust Litigation, which paved the way for the firm’s success in other class action litigation.  He represented hundreds of people injured by the historic Jack in the Box E. coli 0157:H7 outbreak, recovering over $13 million in settlements and a Medical Monitoring and Treatment Trust for the class.  He has led successful efforts to recover millions of dollars for victims of several “Ponzi” schemes, including a case (Getty v. Harmon) in which U.S. District Court Judge William L. Dwyer stated: “Class Counsel achieved real and substantial benefits for members of the Class.  [Their] extensive prior experience in complex class action securities litigation . . . enabled the Class to analyze and achieve this excellent result.” He also led a case on behalf of a class of Seattle Supersonics fans who renewed their season ticket packages for the 2007-2008 season before the team was relocated to Oklahoma City, achieving a settlement that, according to U.S. District Judge Richard A. Jones, “provides meaningful monetary relief to every class member, and does so without the need for any class member to provide a claim form or other submission to establish his or her right to relief.”  Mark has been a partner at Keller Rohrback since 1995, has served on the firm’s Executive Committee since 2001, and has chaired the Antitrust Practice Group since 2007. Most recently, his leadership in an antitrust class action resulted in settlements totaling almost $90 million for registered nurses employed by hospitals in Detroit (Cason-Merenda v. VHS Michigan, Inc.).  In approving the final settlement in that case, U.S. District Judge Gerald E. Rosen told the class representatives: “I think the lawyers, your lawyers in this case, have done a truly outstanding job, as good of a job as I’ve seen lawyers do in a major complex class action in my, what will be very shortly, 26 years on the bench.” Mark also represented the Navajo Nation in a lawsuit alleging Urban Outfitter’s infringement of the NAVAJO trademark and violation of the Indian Arts and Crafts Act.

Since 2004, Mark has volunteered his time as pro bono coordinator at Keller Rohrback. In 2016, Mark was appointed by Governor Jay Inslee to serve as a member of the Board of Trustees of the Legal Foundation of Washington (LFW) and was appointed in 2019 to serve a second three-year term. In 2019 he served as President of that Board. From 2010 to 2015, he served as a board member and officer of the Legal Aid for Washington Fund (LAW Fund) until it merged with LFW. The LFW and the LAW Fund through their Campaign for Equal Justice raise charitable contributions to ensure that justice is a reality, not just for those who can afford it, but for everyone in Washington state. In 2013, the firm received the President’s Award from the LFW for its work in Jerry Cooper, Inc. v. Lifequotes of America, Inc., a case in which Mark helped achieve judgments totaling over $760 million in favor of the plaintiff class. Mark also volunteers at Public Justice and has served as chair of the Consumer Protection, Antitrust & Unfair Business Practices Section of the Washington State Bar Association.
