Hon. Ann I. Jones (Ret.) joins JAMS following a 20-year career as a superior court judge in Los Angeles County. During her tenure on the Los Angeles Superior Court, Judge Jones served in several assignments, including over 12 years in unlimited civil departments, in writs and receivers, and most recently in a complex civil department. She previously served as a United States magistrate judge in the Central District of California.

As both a superior court and magistrate judge, Judge Jones presided over hundreds of diverse matters, including coordinated proceedings and class actions involving pharmaceuticals, medical instruments, wage and hour matters, products liability and health care. She also adjudicated complex coverage disputes involving asbestos-related and environmental liabilities.

Before serving on the bench, Judge Jones was a trial attorney, specializing in antitrust, intellectual property and unfair competition. In that capacity, she participated in issuing the United States Department of Justice’s (DOJ) Antitrust Guidelines for the Licensing of Intellectual Property and the Antitrust Enforcement Guidelines for International Operations. She also served as a regional director for the Federal Trade Commission.

As a neutral, Judge Jones is well prepared and provides each matter with great attention and care. Her reputation as a thoughtful and highly regarded judge derives from her ability to cut through complex matters quickly to ensure that scarce litigation resources are directed to the resolution of critical issues. Her organizational skills, coupled with her courtesy and respect for the participants in the litigation, allow her to work efficiently and effectively with all parties toward timely, well-considered and thorough decisions.
