Hehe, my point was that both qualifying language and an explicit list are not mutually incompatible; in fact we have both in my current assignment of inventions agreement.
Oh, I have no trouble believing that. It's certainly possible to write a more humane AoI. But the purpose of these is mostly to make sure that they don't matter, so I was hoping to reassure the OP that (with basic care) such agreements don't matter and that the 'get a lawyer' and 'this isn't how it is in the UK' pitchfork crowd is simply wrong.
If you have a nicer, professionally-vetted, less scary-sounding AoI, that's terrific. I'd encourage you to post it somewhere as a template.
