Elissa Buchanan joined the firm in 2017.  Her background includes work on antitrust, construction defect, and corporate securities and shareholder litigation. Representative matters include:

  • Opana Antitrust Litigation:  The firm represents a Plaintiff in a proposed class action brought by California indirect purchasers against brand and generic manufacturers of Opana ER.  Plaintiff alleges that Defendants Endo Pharmaceuticals Inc. and Impax Laboratories entered an illegal pay-for-delay or reverse payment agreement whereby Endo provided Impax over $100 million in cash, as well as other valuable consideration, in exchange for Impax’s promise to keep generic versions of Opana ER off the market.  Plaintiff alleges this prevented generic competition and resulted in higher prices.  In addition, Plaintiff alleges that Endo attempted an unlawful product hop in an effort to further raise prices to consumers; and
  • UFC Antitrust Litigation:  The firm is Co-Lead Counsel for current and former Elite Professional Mixed Martial Arts (MMA) Fighters in a class action lawsuit against Ultimate Fighting Championship (UFC), alleging that UFC illegally acquired and maintained a monopoly and monopsony power over Elite Professional MMA fighters, and used that power to suppress their compensation.

Prior to joining the firm, Elissa worked as a contract attorney on construction defect litigation and antitrust and personal injury class actions.  During law school, she interned at California Lawyers for the Arts, where she worked with artist clients to find solutions to copyright and trademark issues.  She also was a technical editor for the Journal of Law and Social Justice and volunteered for Law in Motion, a program that provides opportunities for the law school community to reflect on issues of social justice and access to equal justice through various activities and events.
