About the firm

National Class Action & Trial Lawyers

Federal and state courts frequently appoint the Firm to leadership positions in large, complex class action cases. The Firm’s leadership in these matters has helped secure relief for more than 50 million class members.

Over the past 23 years, Joseph Lyon has represented thousands of clients across all fifty states in consumer class actions, mass torts, and complex individual claims arising from deceptive business practices, data privacy violations, defective product designs, and corporate neglect.  

The Firm has consistently represented individuals and families in complex litigation involving personal injury, economic loss, and environmental harm. Joseph has played a significant role in over 100 consumer class actions, many of which advanced novel legal theories involving digital surveillance and the misuse of confidential healthcare data for marketing purposes.  

Joe has also served in more than 40 multidistrict product liability litigations, helping to secure substantial compensation for his clients. Much of this work has helped fuel industry reforms that resulted in safer pharmaceutical, medical device, and consumer products. Several of these cases rank among the largest mass tort proceedings in history.
