The way I understand it, no.  

The author of the original code needs to assign the copyright to the
FSF.  For various reasons, the FSF _must_ hold the copyright on every
single line of code it distributes.  You can't assign a copyright that
you have no legal right to.  Only the guy with the cool patch, or
possibly his employer can do that.  And just because you incorporate
his code into your own doesn't alter the fact that you don't hold the
copyright to that code.

You could also quite possibly be breaching cool patch author's
copyright.  But that's highly unlikely if he has sent you the patch,
although his employer might have a claim on it.
