Jennifer L. Keller

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 38 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 18 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.)

Just two years earlier Jennifer won California’s largest business jury verdict of 2009 with $350 million awarded to her venture capitalist client in Auerbach v. Daily. She also represented Standard & Poors in United States v. The McGraw-Hill Companies, the government’s civil suit claiming S&P inflated the value of certain mortgage-backed securities. Jennifer was selected as one of S&P’s three trial attorneys. The case settled in 2015 for over $1 billion, which was less than one-fifth of what the government had been demanding.

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. The Los Angeles and San Francisco Daily Journals recognized this win as a Top Verdict in 2024.

In 2022, Jennifer successfully defended Tony, Emmy and two-time Oscar winner Kevin Spacey against actor Anthony Rapp in a sexual battery civil jury trial in Southern District of New York. The jury deliberated only 30 minutes before reaching a unanimous verdict finding Mr. Spacey not liable and denying Mr. Rapp the $40 million he was seeking. The case was covered by the global media.

In 2023, Jennifer won a unanimous federal jury trial verdict for MGA Entertainment against trade dress allegations made by Rapper, T.I. Harris and the O.M.G. Girlz. The plaintiffs were seeking over $100 million in damages claiming that the MGA stole the name, likeness, and trade dress of the OMG Girlz when it created the L.O.L. Surprise! OMG doll line. The jury deliberated less than two hours before reaching its verdict. The Los Angeles and San Francisco Daily Journals recognized this win as a Top Defense Verdict in 2023.

In 2018 Jennifer won two landmark jury verdicts in different areas, each of which was named a “Top Defense Verdict” by the Los Angeles and San Francisco Daily Journals. For one of them, Yellowstone Women’s First Step House v. Costa Mesa, Jennifer won her third CLAY Award (California Lawyer Magazine Attorneys of the Year). In the other, Chavez et al. cv. MassMutual Life Insurance Co., she also won a CVN “Top Verdicts” award. In 2017 Jennifer as co-lead counsel got a not guilty verdict for her developer client Jeffrey Burum after nine months of jury trial in what the California Attorney General called “the largest corruption case in the history of San Bernardino, and possibly California.” The jury was out a little more than two hours before acquitting Mr. Burum of all charges.
