The U.S. Copyright Office is responsible for maintaining records of copyright registration. Although a work is considered copyrighted once it’s in tangible form, registering it with the U.S. Copyright Office provides an additional layer of protection. In case of infringement, i.e., unauthorized use of your copyrighted work, you need to have it registered with the U.S. Copyright Office to file a lawsuit and recover damages.
