2115.6 (D) Renewal Copyright Assigned During Original Term
When the renewal copyright is assigned before it vests, it is a contingency right until the renewal copyright actually vests. An assignor may reserve that right by filing a timely renewal registration (thereby determining in whom the renewal copyright will vest), or by allowing the right to vest automatically. The U.S. Copyright Office will inquire about the date of an assignment and/or the identity of the assignor when this information is useful in establishing or verifying the identity of the vested owner.
