Copyright applies to both published and unpublished works. Further, it is not necessary under the Indian Copyright Act to register with the Copyright Office to get copyright protection. Registration of the work is however a highly recommended because such registration is helpful in an infringement suit. As per the Copyright Act, the Register of copyrights (where the details of the work are entered on registration) is prima facie evidence of the particulars entered therein. The documents purporting to be copies of any entries therein, or extracts from the Register which are certified by the Registrar of copyrights and sealed with the seal of the Copyright Office, are admissible as evidence in all courts without proof or production of the original.
