Kenneth Trujillo-Jamison, Managing Partner of Willenken LLP, is a nationally recognized litigator who represents major corporations in complex, high-stakes disputes. His work is defined by strategic precision, strong courtroom execution, and the ability to align litigation strategy with clients’ broader business objectives, informed by his in-house secondment experience. His practice spans complex commercial, social media, and entertainment litigation, as well as trademark and copyright disputes, and class action defense.
Kenneth regularly represents leading companies in matters involving consumer protection, user-generated content, and emerging issues in technology and media. On behalf of a major social media company, he has repeatedly secured dismissals on the pleadings of claims challenging his client’s moderation of content on its social media platform.
Kenneth has also played a key role in some of the firm’s most significant matters. As a member of AbbVie’s trial team in a high-profile pharmaceutical supply dispute against Takeda in the Delaware Court of Chancery, he examined and defended multiple expert witnesses and contributed to securing a judgment exceeding $500 million. He also helped obtain a complete defense verdict for Disney and Pixar in a copyright infringement case involving Moana and has secured numerous early dismissals of copyright infringement claims in cases nationwide. In addition, he represented a prominent portrait photographer in a right-of-publicity case brought by the rapper Jay-Z.
He also has substantial experience in regulatory matters and consumer class actions, including counseling Southern California Gas Company on regulatory issues before the California Public Utilities Commission. He has represented Procter & Gamble in a dispute involving claims of unfair and deceptive labeling for a leading body wash product, and Mattel and Fisher-Price in false advertising cases involving a widely marketed infant product.
Kenneth’s work has been recognized by leading publications and industry organizations. He was most recently recognized by The Legal 500 in its inaugural 2026 “U.S. City Elite rankings – Los Angeles: Commercial Disputes” and was named a “Future Star” by Benchmark Litigation in 2025 and 2026. The Los Angeles Business Journal recognized him as a “Leader of Influence” from 2024 to 2026 after previously naming him among professionals “Thriving in Their 40s” from 2022 to 2024. Earlier in his career, he was recognized by Best Lawyers as “One to Watch,” named a “Rising Star” by the Minority Corporate Counsel Association, and selected as one of The National Black Lawyers’ “Top 40 Under 40.”
In addition to his practice, Kenneth is a leader in the Los Angeles legal community and in advancing diversity and inclusion within the profession. He serves as President of the Board of Inner City Law Center and as a board member of the California Minority Counsel Program. He is also a member of the Chancery Club of Los Angeles, an invitation-only organization of distinguished lawyers and judges engaged in professional, civic, and philanthropic leadership. He previously held leadership roles with the Housing Rights Center and served on the Board of Trustees of the Los Angeles Copyright Society. He is also an alumnus of the Leadership Council on Legal Diversity, where he was selected as a Fellow in 2022 and a Pathfinder in 2018.
Kenneth began his legal career at an Am Law 200 firm and served as a law clerk to the Honorable Paul J. Watford of the U.S. Court of Appeals for the Ninth Circuit. He earned his J.D. from Yale Law School, where he served as notes editor of the Yale Law Journal.
