Jennifer Keller is one of America’s most successful trial attorneys. She represents both plaintiffs and defendants in a broad range of high-stakes commercial litigation and white collar cases. Chambers USA and Chambers Global rank her among the top commercial litigators in the nation, quoting sources who describe Jennifer as “widely regarded as one of the best trial lawyers in California.” “She has uncanny instincts, a wonderful courtroom demeanor and she’s an extremely clear and effective communicator,” and “is absolutely unflappable in court and builds a strong rapport and credibility with judges and decision makers.” “When you go to trial with Jennifer Keller you come back with a win.” She is a Fellow of the invitation-only American College of Trial Lawyers, considered to be among the highest honors a North American trial attorney can receive. The Legal 500, among the most prestigious international legal directories, recommends Jennifer as one of just 70 “leading trial lawyers” in the entire United States. Jennifer is also a 2018 inductee into the California Lawyers Association Trial Lawyer Hall of Fame, one of only 36 attorneys so honored throughout the years. Benchmark Litigation lists her as one of the “Top 100 Trial Attorneys in America” and among the “Top 20 Trial Lawyers in California,” calling her a “National Litigation Star.” In 2020 and in 2021, Super Lawyers ranked Jennifer #1 in Southern California. “Revered for her versatility and ease in front of a jury … the go-to trial attorney for difficult cases” is how Jennifer is described by The Los Angeles and San Francisco Daily Journals, ranking her as a “Top 100 Lawyer in California” for over 15 years. In three separate years (2019, 2018 and 2012), in starkly different subjects, Jennifer’s trial victories have led to California Lawyer Magazine Attorneys of the Year (CLAY) awards for extraordinary achievements in litigation.
Jennifer made a last-minute entrance as lead counsel for MGA Entertainment in the 2011 retrial of Mattel v. MGA, the epic doll battle popularly known as “Barbie v. Bratz.” Coming into the four-month jury trial just twelve days before jury selection, Jennifer captained MGA to a win Reuters called “an astonishing loss” for Mattel and the LA Times deemed “a stunning reversal of fortune” for MGA. The jury found Mattel had no rights to the Bratz doll line and awarded MGA $85 million in damages for theft of its own trade secrets, to which the judge added $85 million in punitive damages. (While the damages judgment was reversed on appeal, MGA’s $139 million attorneys’ fee award stands.)

In 2024, Jennifer won one of the largest Lanham Act false advertising verdicts in history, in Guardant Health Inc. v. Natera Inc. The jury trial verdict was a complete sweep for Guardant Health: $75 million for corrective advertising, $42 million for disgorgement of profits and $175.5 million in punitive damages. The trial was held in the United States District Court for the Northern District of California.
In 2023, Jennifer represented MGA Entertainment in a trademark and intellectual property jury trial involving its highest grossing doll line. MGA’s LOL dolls gross over $5 billion dollars annually and is MGA’s most popular product. MGA sued OMG GIRLZ for declaratory relief and a finding that it is not infringing on OMG’s mark. OMG filed a counter-claim against MGA and its founder for $100 million alleging violation of the Lanham Act. The jury returned a complete verdict in favor of MGA in less than two hours. The Los Angeles and San Francisco Daily Journals recognized this win as a Top Defense Verdict in 2023.
Jennifer represented a co-founder of a company that sells designer women’s plus size clothing, in her lawsuit alleging tortious interference against the Silicon Valley investor that forced her out. A favorable settlement was reached in 2023 for our client.
In 2022, Jennifer tried and won a unanimous defense jury verdict for Kevin Spacey in the Southern District of New York. Mr. Spacey had been sued for sexual battery by actor Anthony Rapp.
In 2011, as lead counsel for MGA, Jennifer won the retrial of Mattel v. MGA (aka “Barbie v. Bratz”), a billion-dollar “bet the company” copyright infringement and trade secret misappropriation case. MGA had lost a previous trial, been ordered to pay Mattel $100 million in damages, and was forced to surrender the Bratz brand to Mattel. In the retrial, which Jennifer entered just 12 days before trial began, the jury found that MGA owned the entire Bratz brand and rejected all of Mattel’s claims. Additionally, Mattel was ordered to pay MGA $85 million for theft of MGA’s trade secrets, plus $85 million in punitive damages and over $139 million in attorneys’ fees. (Although the damages award to MGA was reversed on appeal, the judgment awarding $139 million in attorneys’ fees stands.) Mattel v. MGA Entertainment et al, USDC Central District of California.
In 2009, Jennifer was lead counsel for the plaintiff in a five-month business fraud jury trial in Los Angeles. The jury awarded $300 million in compensatory damages and $50 million in punitive damages. The case settled in bankruptcy court for $120 million. Auerbach Acquisition Associates v. Daily, LASC.
In 2021, Jennifer represented CashCall Inc. as plaintiff in a landmark legal malpractice suit against an AmLaw 100 law firm, Katten Muchin. This suit was one of the largest such cases ever seen in the country with over $850 million in damages. After years of hard-fought litigation, Jennifer and the K/A team achieved a landmark settlement on the eve of trial.
In 2019, Jennifer and the K/A team settled Broadwood Investments v. The United States, in which the client, Broadcom co-founder Henry Nicholas, sued for relief from an IRS denial of his attempted deduction for distressed Chinese debt. Shortly before trial, the Government settled and allowed a deduction of $40 million plus significant interest. It was a nationwide first for such a deduction to be allowed.
In 2018, Jennifer won a jury verdict for MassMutual Life Insurance Co. in a bellwether class action jury trial in Los Angeles. The class claimed it had been unfairly deprived of dividends. The jury found it had not, which led to the collapse of a nationwide class. The trial was covered live on CVN, which named it one of the Top Defense Verdicts of the year, as did the Daily Journal.
Also in 2018, Jennifer obtained a unanimous federal defense jury verdict for the City of Costa Mesa in the case of Yellowstone Women’s First Step House et al v. Costa Mesa. A network of sober living home operators contended the City had violated the FHA and ADA by passing an ordinance regulating them. For this verdict Jennifer won her third CLAY Award (California Lawyer Magazine Attorneys of the Year) in Municipal Law. It was also featured as one of the Daily Journal’s Top Defense Verdicts of the year.
Jennifer defended Standard & Poors in United States v. McGraw-Hill Companies, in the government’s lawsuit alleging that S&P inflated the ratings of certain mortgage-backed securities. After years of hard-fought litigation, the case settled for $1 billion — less than one-fifth of what the government had initially demanded.
In a 2013 Los Angeles County Superior Court trial, Jennifer along with Kay Anderle as co-counsel for the plaintiff in a breach of contract, fraud and conversion jury trial won nearly $5 million for their client, including $1.4 million in punitive damages. Larian v. Talassazan, LASC-Santa Monica.
Jennifer won a defense jury verdict for a law firm accused of wrongfully terminating the plaintiff, the head of its billing department, due to her alleged “whistleblowing” on billing fraud.
Jennfier has also defended the county CAO in the groundbreaking Orange County bankruptcy litigation, civil and criminal, and before the Securities and Exchange Commission; he was never indicted or fined.
Jennifer achieved a defense verdict for an university in a multi-million-dollar, six-month fraud and misrepresentation jury trial; plaintiffs were students in its inaugural law school class. The jury awarded them zero damages.
Jennifer has represented on civil or administrative matters, several judges, the Orange County District Attorney and the Sheriff.
