September 01, 2025Jeff Ginsberg and Collin Y. HongAs AI becomes more sophisticated at detecting fakes, it is not just changing how brands protect themselves — it has the potential to change the legal framework for determining when platforms themselves might be held responsible for the counterfeits sold on their sites.
