The Complex Appellate Litigation Group LLP is one of the nation's leading appellate specialty boutiques, with more than two-dozen award-winning appellate attorneys and former appellate court law clerks. The firm has no associates, so every one of its lawyers has at least a decade of experience taking on high-stakes appellate matters for businesses, governments, organizations, and individuals.

Recently, the firm:

  • obtained vacatur of a $36.5 million jury verdict against a mechanical engineering corporation sued in a wrongful death action;
  • achieved victory for a large insurance company in a $29 million appeal involving defamation and invasion of privacy claims;
  • won a complete victory across five separate, related appeals totaling more than $13.5 million, in a contract and tort dispute between business founders;
  • and successfully defended on appeal an intellectual property judgment in favor of one of the world’s leading technology firms.


The firm is currently representing a European conglomerate in a contract and tort appeal with more than $100 million at stake, a large insurer in a precedential COVID-related coverage appeal in the California Supreme Court, a Fortune 500 company in an appeal arising from litigation over the largest-ever female-driven Ponzi scheme, and many more. The firm also often embeds its experts on trial teams.
