X64 doesn’t exist. Microsoft used the label for Windows for a while to distinguish from IA64 (Itanium) and 32bit x86 editions of Windows but these days Microsoft moved mostly away from those labels and only uses them when talking about ARM.
I’m just being a little pedantic. But I believe you meant x64?

You did, AMD holds the x64 license, Intel holds the x86.

The x86 license itself doesn’t matter much anymore. Those patents expired a long time ago. Early x86_64 is held by AMD, but those patents are also expiring soon.
There’s more advancements past that which are held by both Intel and AMD. You still can’t make a modern x86 CPU on your own. Soon, you’ll be able to make a CPU with an instruction set compatible with the first Athlon 64-bit processors, but that’s as far as it goes.
