Most provisions of the DMCA are effective on the date of enactment. There are, however, several exceptions. The technical amendments in Title I that relate to eligibility of works for protection under U.S. copyright law by virtue of the new WIPO treaties do not take effect until the relevant treaty comes into force. Similarly, restoration of copyright protection for such works does not become effective until the relevant treaty comes into force. The prohibition on the act of circumvention of access control measures does not take effect until 2 years from enactment (October 28, 2000).
