What elements must a DMCA-compliant copyright notice include on a website?

A Digital Millennium Copyright Act (DMCA) compliant notice on a website must contain specific statutory elements to ensure the safe harbor protections for the service provider and a valid takedown mechanism for rights holders. The required components include a physical or electronic signature of the copyright owner, identification of the copyrighted work claimed to be infringed, identification of the infringing material with sufficient specificity to permit location, contact information of the complaining party, a good faith belief statement that the use is not authorized, and a statement under penalty of perjury that the notification is accurate. Additionally, to maintain safe harbor protection under 17 U.S.C. § 512(c), a website must designate an agent with the U.S. Copyright Office and publicly display the agent's contact details on the site, typically on a dedicated copyright or legal page, ensuring the registration is renewed every three years as mandated by the 2016 electronic registration system update.
