Harrigan Leyh Farmer & Thomsen has earned its reputation as one of the finest trial law firms in the Pacific Northwest.

We don’t call ourselves “IP lawyers,” despite winning a first-of-its kind patent decision during a federal court trial, defeating a $27 million misappropriation claim at a Washington state jury trial, and warding off imposition of a constructive trust over our client’s IP in a case in California where we were hired only after an adverse jury verdict against our startup client and its founders. 

We don’t call ourselves “product liability lawyers” despite winning King County an $18+ million jury verdict and attorneys fees after a six-week trial concerning the defective chemical composition of over six miles of potable water piping installed at the King County Jail.

We don’t call ourselves “mass tort lawyers,” despite successfully defending against the largest wrongful death case in state history and against dozens of lawsuits stemming from one of the most destructive environmental disasters in the state. 

We don’t call ourselves “real estate lawyers,” despite regularly representing and taking to trial or arbitration on behalf of property owners complex cases arising from transactions, construction impact, condemnation, and environmental issues. 

We don’t call ourselves “class action lawyers,” despite having defended against some of the largest class action suits in the state, including some seeking billions of dollars in damages. 

We don’t call ourselves “municipal lawyers,” despite having represented state and local governments in many important and highly public matters.

We don’t call ourselves “appellate lawyers,” despite having argued many cases at the Washington Court of Appeals, Washington Supreme Court, and the Ninth Circuit, and having won a case at the United States Supreme Court.

Instead, we are trial lawyers and problem solvers, hired to handle complex matters for major corporations, public entities, individuals, startups, and international clients at any stage of the proceedings. 

We handle billion-dollar lawsuits and matters far smaller: each invites (and requires) us to collaborate with our clients to design and implement the best strategy to win.

Our clients will tell you that we bring complex problems into focus, take effective action, and deliver clear and convincing messages to judges and juries.  They will also tell you we are always prepared to go the distance but equally prepared to find a more efficient or effective path to a positive outcome.

“Extensive experience in civil litigation, handling antitrust, employment, environmental, intellectual property and real estate litigation, in addition to governance matters and shareholder disputes. Has noted skills in maritime and aviation litigation, representing clients in cargo and property damage, personal injury and insurance coverage disputes.  Market observers comment that ‘they are very experienced trial lawyers’ who provide ‘excellent legal services.’ "
