LitOptix was involved in the significant Sony Music Entertainment v. Cox Communications copyright infringement case, providing sophisticated trial presentation services for Cox’s defense team alongside Winston & Strawn partners Michael Elkin, Jennifer Golinveaux, and Thomas Lane. This landmark case, which initially resulted in a $1 billion verdict in December 2019, involved allegations that Cox failed to adequately address user copyright infringement on its network.
During the 12-day jury trial, our team managed the presentation of highly technical evidence related to Internet service provider operations, network monitoring systems, and digital copyright enforcement mechanisms. We developed clear visual explanations of complex technical concepts, created demonstratives explaining Cox’s copyright policies and procedures, and ensured seamless integration of deposition testimony and digital evidence.
In February 2024, the Fourth Circuit Court of Appeals partially overturned the verdict against Cox, specifically on the vicarious liability claims, creating a significant precedent in digital copyright law. On June 30, 2025, the U.S. Supreme Court granted Cox Communications’ petition to review the case, while denying Sony’s competing petition. Oral arguments are scheduled for December 1, 2025.
The Supreme Court will address whether an ISP can be held liable for “materially contributing” to copyright infringement merely by continuing to provide internet access to subscribers after receiving infringement notices, and whether mere knowledge of infringement constitutes “willfulness” under copyright law. The case has significant implications for internet service providers and how they must respond to allegations of subscriber infringement.
Through these and other cases, LitOptix has consistently demonstrated the ability to handle the most complex litigation challenges across diverse practice areas, providing the strategic visual communication and technical expertise needed for effective courtroom presentation.
