x64 is copy righted only AMD, Intel, and VIA have the rights. There are also some patent protections.
x86 is also copyrighted, but it's expired. Most the parents have expired and it's starting to become more common to 486 and 386's in very cheap embedded controllers.

In the US, copyrights last for 120 years after creation of the work or 95 years after the initial publication, whichever is shorter.
