Copyright Infringement Letter Template for the United States

When someone uses your copyrighted work without permission, a Copyright Infringement Letter serves as your first line of defense under U.S. federal law. This formal document notifies the alleged infringer of your copyright ownership and demands they stop using your protected material. Under the U.S. Copyright Act, you have exclusive rights to reproduce, distribute, display, perform, and create derivative works from your original creations, and this letter helps enforce those rights.

When do you need this document?

You need a Copyright Infringement Letter when you discover unauthorized use of your copyrighted material, whether it's written content, images, music, software, or other creative works. This situation commonly arises when businesses use your photographs without licensing, websites copy your written content, competitors steal your marketing materials, or individuals share your copyrighted work online without permission. The letter is particularly valuable for addressing digital piracy, unauthorized reproduction of published works, and trademark-adjacent copyright violations. You should send this letter promptly after discovering the infringement, as delays can weaken your legal position and may suggest you've abandoned your rights.

Key legal considerations

Your letter must clearly establish your copyright ownership through registration numbers, creation dates, or other proof of authorship. Under federal law, you don't need formal registration to own copyright, but registration strengthens your position significantly and is required before filing a lawsuit. The letter should specifically describe the infringing activity, including exact locations where your work appears without authorization and how the use violates your exclusive rights. You must provide a reasonable deadline for compliance, typically 10-30 days, and clearly state the consequences of non-compliance, including potential legal action. Consider whether the alleged infringement might qualify as fair use under 17 U.S.C. § 107, which allows limited use for criticism, comment, news reporting, teaching, or research. Document everything related to your copyright and the infringement, as this evidence will be crucial if litigation becomes necessary.

Legal requirements in United States

Under the U.S. Copyright Act, your letter must include specific elements to be legally effective. You must identify yourself as the copyright owner or authorized representative and provide complete contact information. The letter should reference the specific copyrighted work, including registration numbers if available, and describe the nature of your exclusive rights. For digital content, consider DMCA takedown procedures under the Digital Millennium Copyright Act, which provides safe harbor protections for online service providers who respond to proper notices. Your demand must be specific about what actions the infringer must take, such as removing content, destroying copies, or paying licensing fees. The letter should reference relevant sections of Title 17 U.S.C. and warn of potential statutory damages, which can range from $750 to $150,000 per work infringed. Keep detailed records of when and how you sent the letter, as proper notice is essential for pursuing legal remedies under federal copyright law.
