A former Drinker Biddle & Reath associate who alleged that four partners at the firm defamed her in performance reviews has lost her bid to revive those claims before a California appellate court.

Ani Avetisyan, who worked in the Philadelphia-based firm’s Los Angeles office from February 2012 to December 2013, sued Drinker Biddle for breach of contract and wrongful discharge, among other claims, after she was terminated and opened a solo practice. Avetisyan also sued several partners alleging libel and slander—Michael McTigue Jr., Sheldon Eisenberg, George Caplan and Kristopher Davis.
