Ray is widely recognized for his expertise in defending “contractors on the battlefield” in tort litigation, and he has established ground-breaking legal principles at the federal appellate level which immunize defense contractors from tort liability arising out of combatant scenarios.

Ray also has an extensive product liability prevention practice, counseling companies on mechanisms for reducing their tort exposure for products and services sold to government and commercial entities. He is significantly involved in counseling companies selling "homeland security" products and services, such as chemical/biological detection devices, perimeter security systems, biometric identity products, and airport security systems. Ray conceptualized and authored key provisions of the SAFETY Act, a new federal statute that is part of the Homeland Security Act of 2002. The SAFETY Act protects companies from tort lawsuits arising out of the sale of homeland security products and services. 

Ray has represented some of the world's largest aerospace, defense and pharmaceutical companies, including Kellogg Brown & Root, Lockheed Martin, BAE SYSTEMS, Boeing, Textron, SAIC, Teledyne, Eon Labs, Unisys, and Philips Electronics. He is a frequent public speaker on risk mitigation techniques.
