This year has been a busy one in the generative artificial intelligence (gen AI) class action litigation landscape. New pleadings were filed, including several new class actions, several consolidated and amended complaints, and one appeal. Several key decisions were issued, including a trio that formed a three-way split of authority on how to determine whether training a gen AI model on copyrighted materials constitutes "fair use" under the Copyright Act. Additionally, one humongous settlement was reached.

Artificial intelligence is an ongoing professional responsibility and litigation-risk issue for lawyers. The California State Bar recently published new guidance. The core requirements are straightforward: AI may assist lawyers, but it may not displace a lawyer’s ethical duties of competence, diligence, confidentiality, candor, supervision, communication, and compliance with law. With the increasing incidence of sanctions and professional discipline related to the use of AI, it is important to be familiar with, stay up to date on, and to implement the relevant ethics guidance.
