Copyright renewal

Copyright renewal has largely lost its significance for works copyrighted in the US in 1964 or after due to the Copyright Renewal Act of 1992. This law removed the requirement that a second term of copyright protection is contingent on a renewal registration. The effect was that any work copyrighted in the US in 1964 or after had a copyright term of 75 years, whether or not a formal copyright renewal was filed. There are some legal reasons for filing such renewal registrations. A further amendment to US copyright law in 1998 extended the total term of protection to 95 years, which now applies to all works copyrighted in 1964 or after.
