The Trouble with the TPP series (Day 1: US Blocks Balancing Provisions) spends the next few days examining the TPP's copyright provisions. One of the most controversial aspects of the 2012 Canadian copyright reform process involved the anti-circumvention provisions, often referred to as the digital lock rules. The U.S. pressured Canada to include anti-circumvention rules, which were required for ratification of the WIPO Internet Treaties, within the copyright reform package. They feature legal protections for technological protection measures (TPMs, a broader umbrella that captures digital rights management or DRM) and rights management information (RMI). There was an enormous amount of scholarly analysis on these issues throughout the reform process. For example, I wrote about the flexibility in implementing the WIPO Internet Treaties, Carys Craig wrote about the negative implications for fair dealing, Ian Kerr wrote about the broader implications of digital locks, Jeremy deBeer focused on the constitutional concerns, and Mark Perry wrote about rights management information. Moreover, David Lametti, now a Liberal MP and the Parliamentary Secretary for International Trade, wrote about the incoherence of the digital lock rules. The academic analysis was decidedly negative about the legal reforms as was the broader public, which made the issue a top priority as part of the 2009 copyright consultation.
