Weren't those patents part of the AMD-Intel cross licensing deal or are there some x86 CPU related patents that are kept separate?

- monocasa 9y agoThose are 1971 IBM patents. It would be interesting to know anything more on the AMD/Intel agreements than the vague "x86 cross licensing" though for sure.

The first will be a quicker read than the second ;). The other commenter mentioned SMT was an IBM patent rather than an Intel one, so that's probably the answer to my question. It seems weird that they wouldn't have just licensed that from IBM as well.
- monocasa 9y agoThe IBM patents have been expired for decades though. There's nothing to licence. But that SEC link is awesome; I though the agreement was completely confidential and we'd only ever see it in a historical context. Thanks!
