Diane Cafferata is a partner in the firm's Los Angeles and Chicago offices.  Her practice involves complex commercial litigations in federal and state courts, where she represents both plaintiffs and defendants.  She has substantial experience in trade secret, patent and other intellectual property matters, class actions, derivatives and other financial matters, construction and real estate disputes, contract and business tort cases, and probate litigation.  Ms. Cafferata’s transnational practice includes several foreign clients and issues of comparative law.

Ms. Cafferata’s background as a JD/MBA, and the breadth of her experience, help her develop creative strategies for advancing her clients’ interests at every stage, before, during or after litigation.  She has become known for her innovative solutions in particularly challenging cases. 

Ms. Cafferata has been recognized nationally and globally for her work on behalf of plaintiffs in complex commercial litigation.  In 2021, Ms. Cafferata was named to “Women of Influence” by the Los Angeles Business Journal. This year, she was named for the third time as one of the Top 50 Women Leaders in Law by Women We Admire.

In July 2020, Ms. Cafferata published Business Litigation Demystified (Little Phoenix Publishing), which hit #1 in four Amazon categories in its first week.  Business Litigation Demystified is a readable and entertaining overview of the U.S. litigation process.  It provides background to business executives, managers and lawyers in domestic and foreign companies that enables them to make better, more informed decisions around dispute resolution issues. In April 2023, Ms. Cafferata published Business Litigation Demystified Discussion Guide (Little Phoenix Publishing), which is designed to stimulate classroom discussion in courses where Business Litigation Demystified is used as a textbook.

Ms. Cafferata teaches trial advocacy and other litigation skills at the firm each year.  She takes great pride in mentoring young lawyers and building teams that impress clients, judges and opposing counsel alike.  Ms. Cafferata has proudly served as counsel for the Rose Bowl Legacy Foundation for the last seven years.
