Jason Wilson’s experience is a rare blend of extensive trial experience, coupled with years of appellate work. Jason’s recent career highlights demonstrate his versatility. In May 2021, on behalf of the fifth largest pharmaceutical company in the world, he conducted a blistering cross-examination of one of the defendant’s (also a large pharmaceutical company) officer, in Delaware Chancery Court. Jason’s client won the liability phase of this proceeding. In September 2023, our client won the damages (phase two) trial in this case. In November 2020, Jason argued a critical issue regarding independent contracting before the California Supreme Court.
Jason is sought after as a last minute trial counsel, and he is also frequently called in to serve as appellate counsel. Jason has taken almost 20 civil matters to trial (both jury and bench) or binding arbitrations. His experience on the appellate side is equally deep. He started his career with two clerkships for two different judges on the United States Court of Appeals for the Ninth Circuit and has handled over 40 different appellate matters in his career so far.
As a result of his unique blend of skills, he is equally adept at telling a compelling story in front of a jury or unpacking a complex legal issue before an appellate panel. Clients turn to Jason to creatively tell their stories to trial courts, juries, and appellate panels.
Valued by leading businesses for his creative thinking, Jason is adept at untangling his clients’ knottiest legal problems. He is in his element when navigating complex litigation challenges and—with over thirty years of practice at the trial and appellate levels—he is a force in the courtroom. In 2016, he was one of only 300 attorneys nationally to be recognized by BTI Consulting Group as a Client Service All Star for his superior client service. Jason provides counsel to Fortune 500 companies in a wide variety of industries, including hospitality, utility, retail, and energy. His experience, aptitude for creative strategy, and passion for intellectual challenges make him an exceptional attorney.
Jason’s combined experience in trial litigation and appeals leads to significant advantages for his clients. An example of this can be seen in his victory for Southern California Gas Company (“SoCalGas”) in a case against a vendor, Syntellect. Jason led the Willenken team to prevail first in a partial summary judgment and then, after an unexpected turn, again in a 49-day rush to trial. After securing a favorable judgment, Jason put on his appellate hat and won two heavily contested appeals. Ultimately, SoCalGas won and collected $9.6 million.
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 case, representing the plaintiff in a jury trial, Jason’s devastating cross-examination of the defendant drove the defendant to settle the case before closing statements for twenty times the pretrial settlement offer. In addition to his trial victories, Jason has served as lead counsel and prevailed on behalf of his clients in many binding arbitrations.
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 The Honorable Judge Diarmuid F. O’Scannlain and the late Honorable Judge Thomas Tang of the U.S. Court of Appeals for the Ninth Circuit. Along with other highly respected trial lawyers, Jason sits on the Board of Visitors of the National Judicial College, and he has been named a California “Local Litigation Star” by Benchmark Litigation for the past five years.
Jason presents the “Trial Is Not a Crisis but an Opportunity for Success” video series. He is a trivia enthusiast and successfully competed on the TV game shows “Win Ben Stein’s Money” and Dick Clark’s “Winning Lines.” He has also watched every one of the 271 episodes in the classic “Perry Mason” show three times.
