Since its genesis in 2015, Los Angeles litigation boutique Hueston Hennigan has seen an ascent that can only be described as astonishing. Formed by a group of commercial litigators who peeled off of California institution Irell & Manella to launch this venture, Hueston Hennigan has forged itself a coveted position as a local litigation shop that has achieved state-wide and even national prominence. The firm is noted for its mission of putting a premium on trial work, a mission that has been fulfilled with rapid momentum on several high-level appointments. “They have just been massively successful,” sums up one East Coast litigator, stating a consensus shared by many. The firm’s client base is remarkably diverse, ranging from individuals to a variety of entities encompassing tech giants, Native American tribes, the Boy Scouts and the California State Bar (to name but a few), with very little repeat business and virtually no “routine” cases. “Hueston Hennigan doesn’t do the ‘cookie-cutter.’ They do really cool, cutting-edge work,” declares a peer, who goes on to confide, “I admit it makes me jealous, and I’m sure I’m not alone!” Seemingly not content with dominating the Los Angeles area, the firm has, within the past year, discreetly planted a flag in the New York market as well, with a further buildout expected.
Firm founder and name partner John Hueston is a trial trailblazer who has carved himself an enviable position even among others in the elite trial lawyer circuit. “I’ve seen trial lawyers rise and fade but John is young and vibrant enough to be in this for the long haul,” opines one peer. A client testifies on Hueston’s behalf. “John is incredibly smart and strategic. He is a true trial lawyer – he relishes the fight and is unafraid of a courtroom.” Hueston’s proven activity as lead counsel on a number of high-level appointments more than supports this near-unanimous acclaim. Hueston is not alone in his trial prowess and activity, however. Moez Kaba has staked himself a position as another of the firm’s lead trial counsel, acting in tandem with Hueston or on his own on some of the firm’s most high-stakes disputes. Kaba made his debut as one of the Benchmark Top 100 Trial Lawyers two years ago, a coveted status made all the more impressive by the fact that he is the youngest appointee to this prestigious list by some distance. More impressive still, his position on that list remains secure again this year, as does that of Hueston, who has appeared every year since the list’s inception. This duo secured a complete defense victory for Boeing when the court overturned the $72 million jury verdict in favor of [now defunct] aerospace startup Zunum (in which Boeing invested) in a high-profile trade-secrets case alleging Boeing’s actions caused Zunum to go out of business. Zunum sought nearly $500 million from Boeing. Acting as replacement trial counsel, Hueston and Kaba handed Boeing a win, defeating Zunum’s claims as well as securing $12 million from Zunum on Boeing’s cross claim. A team composed of Hueston, Kaba and Alison Libeu (who argued the matter before the panel) prevailed at the Ninth Circuit in April 2025, persuading the judges to uphold the firm’s $311 million false-advertising trial judgment and permanent injunction against Vital Pharmaceuticals and its former owner and CEO Jack Owoc. This victory built upon a $293 million jury verdict the firm obtained in 2022 for energy drink entity Monster in a high-profile lawsuit involving claims of false advertising, tortious interference and trade secrets theft against VPX. The jury found VPX and Owoc falsely advertised the alleged “Super Creatine” ingredient in VPX’s billion-dollar Bang energy drink. The jury awarded $272 million against both VPX and Owoc for false advertising and another $21 million against VPX itself for tortious interference and trade secrets theft. In its post-trial judgment, the court added over $43 million in attorneys’ fees, expenses and prejudgment interest to the jury’s award, with over $39 million of that tacked onto the false-advertising claim. Kaba also acted with Robbie Klieger, whose practice has a dedicated entertainment industry niche, in securing a March 2025 triumph when a federal jury awarded client Disney a complete defense verdict in a high-profile suit brought by an animator who alleged Disney infringed his copyrights to develop the blockbuster film, “Moana.” The plaintiff alleged he had passed his materials to a family member who worked on a Disney lot, but the jury decided that the creators of “Moana” never had access to the plaintiff’s outlines and script.
