The Digital Millennium Copyright Act (DMCA) is a United States copyright law that implements two 1996 treaties of the World Intellectual Property Organization (WIPO). It criminalizes production and dissemination of technology, devices, or services intended to circumvent measures (commonly known as digital rights management or DRM) that control access to copyrighted works. It also criminalizes the act of circumventing an access control, whether or not there is actual infringement of copyright itself. In addition, the DMCA heightens the penalties for copyright infringement on the Internet.Passed on October 12, 1998, by an anonymous vote in the United States Senate and signed into law by President Bill Clinton on October 28, 1998, the DMCA amended Title 17 of the United States Code to extend the reach of copyright, while limiting the liability of the providers of online services for copyright infringement by their users.
The DMCA's principal innovation in the field of copyright is the exemption from direct and indirect liability of Internet service providers and other intermediaries. This exemption was adopted by the European Union in the Electronic Commerce Directive 2000. The Copyright Directive 2001 implemented the 1996 WIPO Copyright Treaty in the EU.
Title I: WIPO Copyright and Performances and Phonograms Treaties Implementation Act
DMCA Title I, the WIPO Copyright and Performances and Phonograms Treaties Implementation Act, amends U.S. copyright law to comply with the WIPO Copyright Treaty and the WIPO Performances and Phonograms Treaty, adopted at the WIPO Diplomatic Conference in December 1996. The treaties have two major portions. One portion includes works covered by several treaties in U.S. copy prevention laws and gave the title its name. For further analysis of this portion of the Act and of cases under it, see WIPO Copyright and Performances and Phonograms Treaties Implementation Act.
The second portion (17 U.S.C. 1201) is often known as the DMCA anti-circumvention provisions. These provisions changed the remedies for the circumvention of copy-prevention systems (also called "technical protection measures") and required that all analog video recorders have support for a specific form of copy prevention created by Macrovision (now Rovi Corporation) built in, giving Macrovision an effective monopoly on the analog video-recording copy-prevention market. The section contains a number of specific limitations and exemptions, for such things as government research and reverse engineering in specified situations. Although, section 1201(c) of the title stated that the section does not change the underlying substantive copyright infringement rights, remedies, or defenses, it did not make those defenses available in circumvention actions. The section does not include a fair use exemption from criminality nor a scienter requirement, so criminal liability could attach even unintended circumvention for legitimate purposes. The Unlocking Technology Act of 2013 was introduced to attempt to fix these oversights, which include prohibitions on unlocking one's own cell phone. However, no action was taken by Congress as of the end of 2013.
Title II: Online Copyright Infringement Liability Limitation Act
DMCA Title II, the Online Copyright Infringement Liability Limitation Act ("OCILLA"), creates a safe harbor for online service providers (OSPs, including ISPs) against copyright infringement liability, provided they meet specific requirements. OSPs must adhere to and qualify for certain prescribed safe harbor guidelines and promptly block access to alleged infringing material (or remove such material from their systems) when they receive notification of an infringement claim from a copyright holder or the copyright holder's agent. OCILLA also includes a counternotification provision that offers OSPs a safe harbor from liability to their users when users claim that the material in question is not, in fact, infringing. OCILLA also facilitates issuing of subpoenas against OSPs to provide their users' identity.
Title III: Computer Maintenance Competition Assurance Act
DMCA Title III modified section 117 of the copyright title so that those repairing computers could make certain temporary, limited copies while working on a computer. It reversed the precedent set in MAI Systems Corp. v. Peak Computer, Inc., 991 F.2d 511 (9th Cir. 1993).
Title IV: Miscellaneous Provisions
DMCA Title IV contains an assortment of provisions:
Clarified and added to the duties of the Copyright Office.
Added ephemeral copy for broadcasters provisions, including certain statutory licenses.
Added provisions to facilitate distance education.
Added provisions to assist libraries with keeping phonorecords of sound recordings.
Added provisions relating to collective bargaining and the transfer of movie rights.
Title V: Vessel Hull Design Protection Act
DMCA Title V added sections 1301 through 1332 to add a sui generis protection for boat hull designs. Boat hull designs were not considered covered under copyright law because they are useful articles whose form cannot be cleanly separated from their function.
