The Digital Millennium Copyright Act Guide has specific requirements which must be met in a plaintiff's notification before the claim of infringement can be considered. These "Elements of Notification" are listed below.
The Elements of Notification
Quoted from Public Law 105-304 (U.S. Code, Title 17, Chapter 5, Section 512)
(A) To be effective under this subsection, a notification of claimed infringement must be a written communication provided to the designated agent of a service provider that includes substantially the following:
(i) A physical or electronic signature of a person authorized to act on behalf of the [copyright] owner...
(ii) Identification of the copyrighted work claimed to have been infringed...
(iii) Identification of the material that is claimed to be infringing ... and information reasonably sufficient to permit the service provider to locate the material.
(iv) Information reasonably sufficient to permit the service provider to contact the complaining party, such as an address, telephone number, and, if available, an electronic mail address...
(v) A statement that the complaining party has a good faith belief that the use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law.
(vi) A statement that the information in the notification is accurate, and, under penalty of perjury, that the complaining party is authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.
To present notification of a complaint, contact the designated agent Ellen Mitchell at firstname.lastname@example.org.
