While registering a copyright of an original work is not necessary to obtain full copyright protection, it is a good idea. The benefits of copyright registration are described inCircular 1, Copyright Registration. Registration with the U.S. Copyright Office is necessary in order to bring a lawsuit for infringement. Additionally, if works are registered in a timely fashion (within three months of publication or before an infringement occurs) a copyright owner may claim statutory damages and attorney's fees, in addition to actual damages and profits. Procedures to register a work are straightforward and inexpensive. To register a work, an author submits a completed application form, a $30 filing fee, and copies of the work to the U.S. Copyright Office. For information on registration procedures, see Circular 1, Registration Procedures.
