Copyright registration is advisable, because it expands the remedies for infringement
. Regardless of whether a federal registration is obtained, it is wise (though not required) to place a notice of copyright on all publicly distributed copies so as to give reasonable notice of the claim of copyright.
Under the planned Section 514 (Remedies for infringement
: use of technologies to prevent infringement of copyright works on peer-to-peer computer networks), a copyright owner would not be held liable "in any criminal or civil action for disabling, interfering with, blocking, diverting, or otherwise impairing the unauthorized distribution, display, performance, or reproduction of his or her copyrighted work on a publicly accessible peer-to-peer file trading network, if such impairment does not, without authorization, alter, delete, or otherwise impair the integrity of any computer file or data residing on the computer of a file trader." Before disabling a P2P network, the copyright owner would be required to notify the Department of Justice.
