Jason H. Wilson

Partner/t 213-955-9240/f 213-955-9250


Joining Willenken in 2002 shortly after the firm’s founding, Jason Wilson has successfully tried to a jury or court numerous commercial matters.  His trial victories include defeating a claim that a commercial bank wrongfully honored a letter of credit, defeating a breach of contract claim brought against Hilton Hotels, winning a trademark infringement action, prevailing in a fraudulent conveyance action and winning a fraud action with an award of punitive damages.  Jason has also been lead counsel in many binding arbitrations. His binding arbitration successes includes winning a binding arbitration on behalf of Walgreens in a business acquisition dispute and defeated a claim brought against Beazer Homes, one of the nation’s largest home builders.  On several occasions, Jason’s trial skills have paid dividends for his clients even before the case has been given to the jury for their determination.  For example, in one jury trial, after Jason’s devastating cross examination of the defendant, the defendant settled the case for 20 times the settlement offer he had made the day before trial.  Notably, in this matter, Jason was retained as trial counsel three weeks before trial.   

The focus of Jason’s practice is the representation of Fortune 500 corporations in litigation involving real estate, environmental, intellectual property, class actions, and complex business issues.  Jason has represented numerous Fortune 500 clients as lead counsel, including Southern California Gas Company, Starbucks, Starwood Hotels, Walgreens, Southern California Edison, Shell Oil Company, Hilton Hotels, Sempra Energy, BP and San Diego Gas and Electric Co.  

Jason has also won major victories in a wide variety of civil matters without having to go to trial.  For example, in an indemnity action on behalf of Southern California Gas Company, after winning two different summary adjudication motions and successfully defending the outcome in the Ninth Circuit, Jason won and collected a $9.4 million judgment (which included attorneys’ fees and costs) from a Canadian software company that had refused to provide indemnity for a patent infringement suit.  On behalf of Walgreens, in real estate dispute, at summary judgment, he defeated Plaintiff’s claim that Walgreens’ refusal to open a retail store had caused its former landlord to lose millions of dollars in the sale of the shopping center.  In a confidential settlement, Jason obtained $4 million (for a Fortune 500) from a Fortune 50 based upon a breach of contract claim.  On behalf of Southern California Edison, at the pleading stage, he defeated a challenge from the City of Chino Hills to Edison’s proposed routing of a new power line for a $2 billion renewal energy project.      

Jason graduated with honors from Harvard Law School.  He began his career as a law clerk to the Honorable Diarmuid F. O’Scannlain of the United States Court of Appeals for the Ninth Circuit.  He also clerked for the late Honorable Thomas Tang of the United States Court of Appeals for the Ninth Circuit.  Jason has been a member of the Copyright Society of the United States since 1996 and was a member of the Executive Committee of the Intellectual Property Section of the California State Bar from 2002 to 2006.  Jason was a member of the Board of Governor of the Japanese American Bar Association of Greater Los Angeles from 1997 to 2001.  He has been recognized in The American Lawyer as a Top Rated Lawyer in Commercial Litigation and is a Life Member of the Million Dollar Advocates Forum, an organization open to top trial lawyers in the United States.  He is also on the Board of Visitors of The National Judicial College.   

Jason is an active speaker and has given numerous speeches.  He has spoken on intellectual property topics many times, including speeches before the Intellectual Property Sections of the State Bars of Utah, Colorado and California.  Jason has also spoken before several chapters of the Association of Corporate Counsel (“ACC”).  For example, in May 2015, before the Ontario Chapter of ACC in Toronto, Canada, he presented a talk entitled:  Risk Management:  Top 10 Ways to Avoid Heartbreak in American Litigation.   This presentation, which highlighted the quirks of American litigation which Canadian in-house counsel find surprising, was based upon Jason’s frequent litigation for (and against) Canadian companies.   

In 2016, BTI Consulting Group recognized Jason as one of 312 attorneys nationwide who provide superior client service.  Read more here. Most recently, Benchmark Litigation named Jason a Local Star.

Jason is an avid baseball and soccer fan.  He enjoys reading history, participating in trivia contests (he has appeared in two TV trivia shows), traveling and spending time with his wife and daughter.
