I am not a lawyer, nor even a US citizen. Talking to someone who is both 
may be a good idea.

Unless otherwise granted by the copyright holder, by default the copyright 
of a derived work (in the copyright legan sense) is held by the owner of 
the original copyright and not the crator of the derived work. So no, the 
patches are owned by Intel as well.

The gpl has wording the explicitly grants the creator of derived works the 
ownership of the copyright for the derived part. 

All of this is from memory based on a Usenix tutorial on basic ip law in
the USA. It may very well be wrong.
