Kenneth Trujillo-Jamison is the managing partner of Willenken LLP. Kenneth uses his sharply honed analytical and strategic skills to efficiently handle his clients’ most complex and challenging matters. Having spent time on secondment, Kenneth knows the importance of aligning litigation strategy with his clients’ business objectives. In 2024, Kenneth was recognized by the Los Angeles Business Journal as a “Leader of Influence: Litigators & Trial Attorneys” and a “Leader of Influence: Minority Attorneys.” He also was recognized by the Los Angeles Business Journal as a “Leader of Influence: Thriving in Their 40s” from 2022-2024, and by Best Lawyers as “One to Watch” in 2020 and 2021.
Kenneth’s successes in the courtroom abound. As but one example, as a member of AbbVie’s 100%-diverse trial team in “one of the five big healthcare lawsuits” of 2020, Kenneth helped convince the Delaware Chancery Court to find Takeda Pharmaceutical Co. liable for breach of contract. At trial, Kenneth examined and defended multiple expert witnesses. The court ultimately awarded a judgment that, with prejudgment interest, exceeded $500 million.
Kenneth also has deep experience litigating entertainment matters. For example, Kenneth was part of a team that achieved a total defense verdict for Disney and Pixar in a copyright infringement case involving the film “Moana.” He also represented a prominent portrait photographer in a right-of-publicity case brought by the rapper Jay-Z. And Kenneth has convinced judges in numerous cases across the country to dismiss on the pleadings copyright infringement claims involving motion pictures, ending those matters before discovery.
Kenneth also is experienced defending technology companies in litigation about users and user-generated content posted on their platforms. He has obtained dismissal, on Communications Decency Act grounds, of several cases seeking to hold a prominent social media company liable for claims arising from the suspension of users from its platform.
Kenneth also has experience in consumer class actions. He has, for example, represented Procter & Gamble in a dispute involving claims of unfair and deceptive labelling for a popular body wash product, and Mattel and Fisher-Price in false advertising cases involving a popular infant product. Kenneth also has experience counseling Southern California Gas Company on regulatory issues before the California Public Utilities Commission.
Aside from his practice, Kenneth is a leader in the Los Angeles legal community. Kenneth is a past member of the Board of Trustees for the Los Angeles Copyright Society, a members-only organization of attorneys who practice in copyright, trademark, communications, and related areas that meets monthly to hear speakers present on varied topics of vital and current interest to practitioners. He is also the President of the Board of Inner City Law Center, which works towards ending the homelessness crisis by providing free legal services to the poorest and most vulnerable residents of Los Angeles, and a past president and current board member of the Housing Rights Center, Los Angeles’ largest public interest law organization dedicated to enforcing fair housing laws.
Kenneth is also active in promoting diversity, equity, and inclusion in the legal community. He is a member of the Board of Directors of the California Minority Counsel Program (CMCP) and the past Chair of CMCP’s Ambassadors Council. He also served on CMCP’s 2019 Annual Business Conference Planning Committee. Finally, Kenneth was also a 2022 Fellow and a 2018 Pathfinder in the Leadership Council on Legal Diversity program.
Prior to joining Willenken, Kenneth practiced at Munger, Tolles & Olson LLP. He also served as a law clerk for The Honorable Judge Paul J. Watford of the U.S. Court of Appeals for the Ninth Circuit. In his time away from the law, Kenneth enjoys listening to podcasts and spending time with his wife and his two young children.
