The Trouble with the TPP series focuses today on the TPP’s effort to regulate how Internet providers and hosts address allegations of copyright infringement on their networks and sites (prior posts include Day 1: US Blocks Balancing Provisions, Day 2: Locking in Digital Locks, Day 3: Copyright Term Extension). The goals of the U.S. and Canadian government in the negotiations were clear from the outset: the U.S. wanted to export its DMCA notice-and-takedown system to the rest of the TPP, while Canada wanted to preserve its newly created notice-and-notice approach (more on the notice-and-notice system, which does a better job of striking a balance and preserving user privacy, here). In fact, Canada rushed through the notice-and-notice system without regulations (causing major problems of misleading notices) in order to argue that it should not be required to adopt the U.S. approach.
