Lauded as one of the “brightest litigators across the U.S.” in Benchmark Litigation, Allison Libeu provides creative, practical, and strategic counsel to help her clients resolve complex commercial disputes and protect their business interests. Recent highlights include scoring a “record” verdict in a Lanham Act trial, an arbitration victory that is among the biggest trademark awards in the U.S., and a complete defense win in a racketeering and fraud suit against one of the world’s largest technology companies.

Ms. Libeu litigates high-stakes business disputes across a variety of areas, including business torts, contracts, trademark infringement, and trade secrets. Her practice includes trial and appellate litigation in federal and state courts, U.S. and international arbitration, and administrative and regulatory proceedings.

Ms. Libeu regularly secures victories as lead or co-lead counsel in high-profile arbitrations and trials, including the recent “record-breaking” $293 million verdict for Monster Energy Company in a false advertising, tortious interference, and trade secret case. The verdict — believed to be the largest Lanham Act award ever — came after a five-week trial against Vital Pharmaceuticals, Inc. (VPX) and its CEO for falsely advertising the “Super Creatine” ingredient in their billion-dollar Bang energy drink. The trial judge upheld the verdict and found the case “exceptional,” awarding Monster $43 million in attorneys’ fees, expenses and prejudgment interest

Earlier that year, Ms. Libeu also obtained a $175 million award — believed to be the largest-ever U.S. trademark infringement award — for Monster in an arbitration against VPX for breach of contract and trademark infringement relating to VPX’s misuse of the “Bang” trademarks.

Ms. Libeu served as lead litigation counsel to Monster in its 2023 acquisition of Bang Energy for $362 million. The acquisition was preceded by VPX’s petition for bankruptcy due to the almost $500 million in judgments Ms. Libeu obtained for Monster. The M&A Advisor awarded Hueston Hennigan with “Restructuring Deal of the Year” for her work in the bankruptcy matters and on Monster’s acquisition of Bang Energy.

Ms. Libeu is handling numerous high-profile pending matters, including co-leading the team defending Amazon and its Twitch subsidiary against highly complex litigation attempting to hold social media companies liable for the racially motived shooting of multiple people by a social media user, as well as representing Epic Games in cases across multiple jurisdictions claiming that the company intentionally designed its Fortnite video games to addict players.

Ms. Libeu has been named to the Daily Journal’s lists of “Top 40 Under 40” and “Top Women Lawyers,” included on the nationwide lists of “Top 250 Women in Litigation” and “40 & Under” and recognized as a “Future Star” by Benchmark Litigation, and named among “Leaders of Influence: Litigators & Trial Attorneys” by the Los Angeles Business Journal.
