The Copyright Amendment Act of 2012 made several changes to clarify rights over artistic works, films, and sound recordings to address challenges in the digital era and cyberspace. It introduced definitions for terms like "commercial rental" to meet obligations under international treaties. The amendments also aimed to facilitate access to copyrighted works through additions like compulsory licensing, statutory licensing, and fair use provisions for digital works. Other changes strengthened protection of technological measures, digital rights management information, and included administrative amendments.
