Jennifer 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.” 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 63 “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 35 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 10 years in a row. 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 L.A. 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. Recently she 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 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.

Jennifer is listed annually in “The Best Lawyers in America®” and is among the Lawdragon 500 Leading Lawyers in America. Jennifer is a fellow of the Litigation Counsel of America, an invitation-only organization limited to the top one-half of one percent of the nation’s attorneys.

Jennifer is also active in the community. She is the former President of the Orange County Bar Association and served for many years as a Trustee of Chapman University. She counts as present and former clients judges, public officials, law enforcement officers, CEOs, CFOs, lawyers, physicians, professional athletes, entertainment industry executives, actors, venture capitalists and entrepreneurs. Jennifer’s past and present institutional clients have included Fortune 100 corporations, other publicly-traded corporations, and large privately-held companies.

Representative Matters

  • 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, she and her team achieved a settlement on the eve of trial.
  • In 2019, Jennifer and her team settled Broadwood Investments v. The United States, in which her 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 successfully defended the City of Costa Mesa on Yellowstone Women’s First Step House et al v. Costa Mesa, in which a network of sober living home operators contended the City had violated the FHA and ADA by passing an ordinance regulating them.  A unanimous federal court jury disagreed. 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 Journals’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 and 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.
  • She 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 secured an acquittal after jury trial for a lawyer charged with engineering the largest insurance fraud case in the history of California; a massive RICO prosecution over an alleged $200 million dollars’ worth of over-billing insurance carriers for legal fees.
  • She has represented on civil or administrative matters, several judges, the Orange County District Attorney and the Sheriff.
