What The Lyon Firm does
The Lyon Firm is a Cincinnati, Ohio-based plaintiff-side law firm specializing in class action and product liability litigation on a contingency-fee basis. Founded by Joseph Lyon, the firm has represented thousands of individual clients across all fifty states and has participated in more than 40 Multi-District Litigations in Federal and State courts, with Joe Lyon appointed as lead class counsel in numerous State and Federal Consumer Class Actions. The firm operates from four physical offices — Cincinnati, OH (headquarters); Mayfield Heights, OH; St. Louis, MO; and Irvine, CA — and markets nationally through content marketing, organic search, and earned media in outlets including AP, Bloomberg, Chicago Tribune, Wall Street Journal, and NBC.
The firm's core service portfolio spans 15+ practice pages, anchored in product liability (defective products, auto defects, defective medical devices, pharmaceutical injury), class action litigation (consumer protection, antitrust, data privacy, TCPA violations, employee misclassification), and toxic tort work (asbestos exposure, environmental contamination, hospital data breaches). Sub-segments with notable outcomes include healthcare data breach class actions ($30M+ in aggregate settlements, including Christ Hospital Pixel, Advocate Aurora Pixel, and a major insurance brokerage data breach covering 21 million customers for $32.8M). The firm employs a small attorney team (Joseph Lyon plus Clint C. Watson, Kevin Cox, and Suvir Dhar) supported by national co-counsel relationships across the plaintiff bar.
The business model is a pure contingency-fee professional services offering: clients pay no fees or costs unless recovery is achieved, the firm advances all litigation costs and accepts full financial risk, and revenue flows to the firm as a percentage of settlements and verdicts. Lead acquisition is sales-led, driven by direct consultation requests via the firm website and phone, with top-of-funnel demand generated through blog content and earned media. There are no disclosed AI/ML capabilities, no proprietary technology platform, and no external institutional investment. The firm is privately held with no parent company, and revenue figures are not publicly disclosed.
