First Apple and now Microsoft. Do they license the patents from Intel or did they expire? Or are they working around that somehow?
Important to note that this doesn't really apply to Apple Silicon. Rosetta II isn't X86 emulation, it's a translation layer - big technical difference.
But it can be different. Depends on the magic formulas you use for your claims, and whether you are actually permitted to patent software in the first place (with or without other magic formulas usually stating that said software is executed by some hardware).
And in places where it is not supposed to be possible to patent software, patent offices are usually nevertheless accepting them, because it gives them money so why not? :P
TLDR it is a mess. Depends on an insane nmuber of contextual factors, and as unpredictable as the outcome of Oracle vs. Google before the verdict. Or maybe even more unpredictable.
I think you're thinking of copyright? Where reverse engineering is allowed for interoperability.
Wait a second, one of us is behind the times. I thought Brexit happened earlier this year?
>The United Kingdom (UK) left the European Union (EU) on 31 January 2020. A transition period is now in place until 31 December 2020.
As far as I can tell from my distant vantage point on the west coast of North America, there is very little doubt left. Brexit has already happened and most of the fallout will be settled by the end of this month. I supposed you could say that it's still in a constant state of happening, but it's well past the point of "not happening" as far as I can tell.

That's my expectation at least. They may feel the full pain of a full exit on Dec 31, I doubt they'll want to continue in that state for very long.
There's also the possibility of yet another extension on the transition period.
The UK ceased being in the EU in January, and transitioned into a temporary EEA membership, subject to most EU law. That comes to an end in a few days; at that point what happens next depends on the outcome of negotiations. There's certainly a world in which EU patent rules continue to apply to the UK; in fact, that would probably have been the default assumption until the British government went off the deep end.
So, if you use 'Brexit' to mean purely the legalistic act of leaving the EU, then yes, it's happened. However, effectively none of the _effects_ of Brexit have happened yet.
