you're not automatically entitled to use or benefit from the IP developed by others and then disclosed to you just because you signed a paper that promises to pay you for work. maybe it makes more sense where your opponent is a horrible but huge company like facebook but this move can kill development of sensitive or novel tech by underfunded entrepreneurs. it is a mistake for the USA. maybe you guys should downvote me more while you ride around in your teslas powered by slave labor batteries.
I think you are confusing non-compete and NDA, IP rights, non solicitation agreements and the like. You can go work for competitor, but it doesn't allow you to use any of your previous employer's IP, poach colleagues, clients etc. Doesn't prevent you from using your expertise and come up with novel things.
And some big companies do care that you don't do it, because they don't want to go into litigations because layers like to target fat cats.
i'm not confusing them. i know what i wrote. humans cannot avoid using IP from previous companies. what's your background ? (are you technical?) and there's more to this than existing big companies and their disposable funding.
I don't think my background is important here. But I'm technical if you need to know.
I had first hand experience of colleagues specifically not working on certain parts of projects because of NDA from their previous employments.
What does tesla batteries have anything to do with this? And california has banned them for years but its tech sector seems to be thriving and much, much stronger than anywhere in Europe that actually enforces them. So what are you basing your prediction on?
