Registration of one’s copyrighted work with the Copyright office is not required to obtain a Copyright. In fact, one need not actually publish their work for it to be copyrighted. Rather, copyright protection attaches upon the creation of the work.
While this is true, there are certainly advantages to registration. I was reminded of this recently while reviewing this intellectual property blog from the firm Shepperd Mullin in Washington, DC. Particularly useful is the linked article by Matthew Clanton discussing the advantages of registration from the additional statutory rights for recovery to objective evidence that the work is copyrighted. And when registration costs only $35 to $45 per work, and can be done online at www.copyright.gov, the down side is minimal.
So, think about it.
