Is preregistration a substitute for registration?
No. Preregistration is not a form of registration but is simply an indication of an intent to register a work once the work has been completed and/or published. When the work has been completed, it may be registered as an unpublished work, and when it has been published, it may be registered as a published work. Preregistration of a work offers certain advantages to a copyright owner pursuant to 17 U.S.C. 408(f), 411 and 412. However, preregistration of a work does not constitute prima facie evidence of the validity of the copyright or of the facts stated in the application for preregistration or in the preregistration record. The fact that a work has been preregistered does not create any presumption that the Copyright Office will register the work upon submission of an application for registration. A person who has preregistered a work must register the work within one month after the copyright owner becomes aware of infringement and no later than three months after first publication
