That doesn't seem to be the US Government position, at least during the 
last administration. To me <https://www.copyright.gov/circs/circ14.pdf> 
says that you only own the new bits, and, in fact, if you want to 
register the copyright, you must specifically identify in which bits you 
have copyright and in which you don't.
