The big picture

AI litigation is evolving into a cross-jurisdictional, cross-sector, and cross-regulatory phenomenon. The surge in cases highlights the growing legal risks associated with AI deployment, particularly around copyright, regulation, and product liability. This trend will shape how organizations govern, disclose, and deploy AI for years to come.
