Jason H. Wilson

Partner/t 213.955.9240/f 213.955.9250


With over 30 years of practice at the trial and appellate levels, Jason Wilson is a force in the courtroom. He has tried 15 cases to a jury, judge, or arbitrator, and is often retained as trial counsel mere weeks before trial. Recognized by BTI Consulting Group for his superior client service, Jason provides measured and skilled counsel to Fortune 500 companies across a range of industries in litigation matters involving real estate, environmental, intellectual property, class action, and complex business issues.

A shrewd and adept litigator, Jason’s courtroom triumphs include defeating a claim that a commercial bank wrongfully honored a letter of credit, winning a trademark infringement action, prevailing in a fraudulent conveyance action, defeating a breach of contract claim brought against a premier hotel chain, and winning a fraud action with an award of punitive damages. On several occasions, Jason’s sharp trial skills have paid dividends for his clients even before the case has been given to the jury for their determination. In one particular case representing the plaintiff in a jury trial, Jason’s devastating cross-examination of the defendant drove the defendant to settle the case for 20 times the initial settlement offer made the day before trial. 

In addition to his trial victories, Jason has served as lead counsel and prevailed on behalf of his clients in many binding arbitrations. He has also won major victories in a wide variety of civil matters without having to go to trial, most notably in an indemnity action where he won and collected a $9.6 million judgment from a plaintiff that had initially refused to provide indemnity for a patent infringement suit.

Jason practiced at an Am Law 100 firm before joining Willenken shortly after its formation. He began his legal career as a law clerk for Judge Diarmuid F. O’Scannlain and the late Judge Thomas Tang on the U.S. Court of Appeals for the Ninth Circuit. When he is not litigating, Jason enjoys traveling and spending time with his wife and daughter. An avid baseball and soccer fan, Jason is also a trivia enthusiast and has competed on the television game shows “Win Ben Stein’s Money” and “Winning Lines.”
