x86 is a de facto standard.
I'm guessing Qualcomm will lose.
> Existing in actuality, especially when contrary to or not established by law
There is no standards committee approving X86 processor designs/features/functionality, with a goal of vendor interoperability, thus, there is no 'standard' for X86.
That's why it's "just" a de facto standard, since it's still pretty much the only thing used in its product category.
