Summary

Lord Justice Richard Arnold's Charles Clark Memorial Lecture in 2026 addressed the increasing strain on copyright's territorial architecture due to global markets, platforms, and data flows, particularly in the context of AI. Arnold argued that while the international copyright system remains territorial, its operational porosity means national rights and infringements have global economic and technological effects. He highlighted exhaustion, specifically the U.S. Supreme Court's move to international exhaustion in *Kirtsaeng* (2013), as a doctrine capable of disrupting geographic price differentiation. Arnold also discussed how legal systems classify "digital copies" differently from physical ones, as seen in the EU's *Tom Kabinet* decision regarding ebooks. He contrasted this with the U.S. Internet Archive / controlled digital lending case, emphasizing how U.S. fair use precedents can create global shockwaves. The lecture also covered extended collective licensing and the emerging fault lines in AI litigation, where territoriality and specific legal doctrines lead to varied outcomes for similar activities.

Key takeaway

For legal and technical leaders navigating global content strategies, understand that copyright's territorial nature is increasingly porous, meaning national legal decisions can have worldwide commercial implications. Your teams should prioritize legal counsel that can assess cross-border risks, especially concerning data acquisition for AI training and digital content distribution, to avoid inadvertently exposing your organization to liability or undermining your market position.

Key insights

Copyright's territorial framework faces significant strain from global digital markets and AI, creating complex cross-border legal challenges.
