Digital Millennium Copyright Act (DMCA), is a federal statute that addresses a number of copyright issues created by the use of new technology and the Internet including digital rights management (methods for stopping infringement), and certain rights and privileges (safe harbors) that protect Internet Service Providers. Public Law 105-304, was signed into law on October 29, 1998, by President Clinton to bring the World Intellectual Property Organization (WIPO) Copyright Treaty of 1996 into the laws of the United States. It combined four proposed bills as well as some other revisions to copyright law that were needed to fill-in gaps within U.S. law that the WIPO Copyright Treaty addressed. Some of the most important revisions in the DMCA increased protections against new methods of infringing copyrighted works, especially those through the internet. The DMCA, while recognized as making many needed changes to copyright laws, has been critiqued and increasingly so as being overprotective in different ways, including limiting the ability of consumers to use products they purchase.
The “WIPO Copyright and Performances and Phonograms Treaties Implementation Act of 1998” in the DMCA added Chapter 12, Copyright Protection and Management Systems, to the Copyright Act. While United States copyright law arguably met most of the provisions in the WIPO treatises, it did not address technological measures to help stop copyright infringement or other copyright management systems. The DMCA resolved that by first making it a violation to circumvent a technological measure to access a copyrighted work, and then making it a violation to traffic in devices whose purpose is to circumvent the technological measure to either access the work or otherwise infringe the copyright. There are a number of narrowly-tailored exceptions provided, as well as a triennial rulemaking by the Library of Congress to exempt classes of copyrighted works.
The “Online Copyright Infringement Liability Limitation Act” added Section 512 to the Copyright Act, providing four distinct safe harbors for online service providers. If the conduct of a service provider meets all the specific requirements of a safe harbor, the service provider will not be liable for monetary damages for copyright infringement, although injunctions to stop future infringement are possible. The safe harbor for user information residing on the service providers’ systems includes a “notice-takedown-putback” provision where the service provide takes down information after proper notice is received from the copyright owner alleging infringement, and can be restored if the user challenges the takedown after sufficient time to file a copyright infringement suit.
When most people refer to the DMCA, they are talking about one or both of those provisions. But it included many other things, some not even about digital information or copyright. The “Vessel Hull Design Protection Act” added Chapter 13 to Title 17. Although not a copyright provision, it gave the Copyright Office a new role in protecting an “original design of a useful article” (where “useful article” is limited to boat hulls). It was intended to replace the state law struck down by the Supreme Court in Bonito Boats, Inc. v. Thunder Craft Boats, Inc.
With the “Computer Maintenance Competition Assurance Act,” the DMCA also broadened Section 117 of the Copyright Act to allow third-party maintenance organizations to used software licensed to a computer’s owner or lessee as part of their maintenance activities, overriding the Ninth Circuit’s 1993 decision in MAI v. Peak.
The DMCA also contained a number of miscellaneous changes to copyright law, including an update to the Section 108 exemptions for libraries and archives.
