Oh, does the patent also prevents software emulation? At any rate, what even counts as emulation?that legal stuff is way above my paygrade...
Lets say someone invents and patents doing arithmetic on numbers stored on a stack. They could keep anyone else from doing stack based math until the patent expires. It doesn't matter how you implement it - a work-alike chip, translation to different instruction encoding, a software simulation, analog simulation of the transistor circuit, guru moving beads on a board - anything operating on numbers on a stack is a violation.
Fortunately, stacks were invented many decades ago. The patents at issue are for many generation newer ideas. Luckily for the broader industry, these ideas are mostly hacks to paste better performance math onto the x86 instruction set.
One of the linked articles shows that Intel has patents on the "extended arithmetic" instructions. This is basically just an "add with carry" instruction that uses the oVerflow flag as an alternate Carry flag. There's nothing new about add with carry. However, repurposing a different flag, no matter how minor a concept, might be patentable - even though this was just Intel fixing their own instruction set design ****-up.
Compiling into x86 bytecode is fine because then you'll just be using Intel's (or a licensee's) product. Disassembly is fine because you won't be using the patent - but beware, the mnemonics are copyrighted.
