In the renewal of copyright, the new American code follows the previous law in differentiating the persons entitled to renew the copyright. It provides (sec. 23) that in the case of a posthumous composite or corporate work originally copyrighted by the proprietor thereof or a work made for hire, the proprietor of such copyright shall be entitled to a renewal; but in other cases, including a separately registered contribution by an individual to a composite work, the author or the widow, widower or children, or, if such be not living, the author's executors or next of kin shall be entitled to a renewal. This means that there can be no renewal by an assignee proprietor, and that in the absence of natural heirs of a personal author, no person is entitled to a renewal of his copyright. The new law has been specifically construed to this effect by the Attorney-General in his opinion of February 3, 1910. It should be noted that the word "administrators," included in the provision as to original application (sec. 8), is omitted from the provision as to renewal (sec. 23) including renewal of existing copyrights (sec. 24), indicating that while an author may make bequest of copyright for the renewal term, which right may then be claimed by his executor, the right to renew lapses when he makes no will and has no next of kin to inherit the right of renewal. {Sidenote: Assignments} Specific provision as to the method and record of the transfer of copyrights by assignments are contained in the following provisions of the code of 1909: "(Sec. 42.) That copyright secured under this or previous Acts of the United States may be assigned, granted, or mortgaged by an instrument in writing signed by the proprietor of the copyright, or may be bequeathed by will. "(Sec. 43.) That every assignment of copyright executed in a foreign country shall be acknowledged by the assignor before a consular officer or secretary of legation of the United States authorized by law to administer oaths or perform notarial acts. The certificate of such acknowledgment under the hand and official seal of such consular officer or secretary of legation shall be _prima facie_ evidence of the execution of the instrument. {Sidenote: Assignment record} "(Sec. 44.) That every assignment of copyright shall be recorded in the copyright office within three calendar months after its execution in the United States or within six calendar months after its execution without the limits of the United States, in default of which it shall be void as against any subsequent purchaser or mortgagee for a valuable consideration, without notice, whose assignment has been duly recorded.
