Difficulty: Moderately Easy
Step1
Register your copyright at the US Copyright Office before an infringement situation occurs, if possible (see Resources below). Even if you are already in the midst of a legal suit to protect your material, it is still worthwhile to register the copyright.
Step2
Consult with a lawyer who specializes in copyright law. Especially if the matter goes to court, you may need legal help to provide proof of your copyright.
Step3
Obtain a certificate of registration from the US Copyright Office to demonstrate your copyright. This is the ideal proof of your copyright.
Step4
Provide copies of the work in question and the date of production for an informal proof of copyright. While such documentation is not acceptable in a court of law, some Internet service providers will consider it adequate proof for an online take-down notice.
Step5
Offer published copies of your work. A published copy would include an independently published magazine, book or other medium. Publishers usually register copyrights of whole works, which your material may be included in, and this can act as proof.
