I mean, x86_64 came out in 2000. The basic patents behind it should be expiring right about now.

There are many patents around microarchitectural optimizations and also features like performance monitoring, virtualization, etc.

It happened a few times to me to see a new, still undocumented, feature mentioned in Intel slides, and consult the patent to learn more about it.

It's not like AMD and Intel agree on how to do performance monitoring and virtualization. What's a third implementations in the grand scheme of things?
