O’Melveny Worldwide

Jonathan Schneller brings a strategic eye to his clients’ most challenging matters, defending major companies in novel mass-tort cases and high-stakes litigation against government entities. Jonathan is a leading expert in public-nuisance law and has extensive experience defending internet companies and manufacturers in lawsuits, class actions, and state Attorney General investigations alleging harms from their products and services. His briefing in high-profile matters has been described in the media as “forceful, cogent,” and “passionately written.”

Jonathan recently played a lead role in the following matters:

  • Coordinating legal strategy for a pharmaceutical company’s defense of governmental opioid lawsuits. Among other successes, Jonathan helped secure a landmark 2021 appellate reversal in the Oklahoma Supreme Court rejecting the novel public-nuisance theories driving the nationwide opioids litigation.
  • Coordinating legal strategy for an auto manufacturer’s defense of tort lawsuits relating to a social media “challenge” involving the manufacturer’s vehicles.
  • Defending a social media company in wrongful death and personal injury lawsuits alleging that online content provoked a mass shooting.
  • Securing dismissal for a social media company of a putative class action alleging that online “challenges” harmed school districts.
  • Securing dismissal for a financial services company of a putative class action alleging that the use of a voice-matching security tool violated California privacy law.
  • Representing a health insurer in an action against the US Department of Health and Human Services challenging a Medicare audit regulation.
  • Defending a health insurer against a false-claims lawsuit by the US Department of Justice involving the interpretation of Medicare regulations.

Before rejoining O’Melveny, Jonathan served as a Deputy Federal Public Defender in Los Angeles. Specializing in federal criminal appeals, he repeatedly beat the odds, winning new trials or vindicating his clients altogether. In his pro bono practice at O’Melveny, Jonathan has secured the release of a juvenile offender sentenced to 80-years-to life for an offense he committed at age 14, authored an amicus brief in the Supreme Court’s landmark same-sex marriage decision, Obergefell v. Hodges, and crafted arguments on voting rights, capital punishment, Social Security, and immigration law.

Jonathan lives in Los Angeles with his daughter, Maddie, and is an active member of the community, serving on boards for the RAND Corporation Institute for Civil Justice and the Los Angeles Metropolitan Debate League.

Jonathan graduated cum laude from Princeton University, where he was national champion of the American Parliamentary Debate Association, and graduated summa cum laude from Harvard Law School, where he was an editor of the Harvard Law Review and winner of the First-Year and Second-Year Sears Prizes. After law school, he served as a clerk to the Honorable Elena Kagan of the Supreme Court of the United States and the Honorable Stephen Reinhardt of the United States Court of Appeals for the Ninth Circuit.
