Certain types of eligible works (original works of authorship fixed in a tangible medium of expression) are eligible for preregistration including movies, music, books, musical compositions, software and pictures.  Preregistration permits a copyright owner to file a civil action for infringement of a United States work/copyright that would otherwise not be permitted without registration.  With preregistration, registration must be completed three months after publication of the work.  Failure to timely register may lead to the subsequent dismissal of an infringement action that was initially authorized to be filed on the basis of preregistration.  Preregistration can assist a copyright owner to protect a valuable copyright that may be at greater risk of infringement.
