Yes, this is part of California law. I forget the url, but if you google for it, it is less than one page. You can just print it out and bring it with you and say “FAANG does this, and I expect it as well”
It's still vague. What about something created prior to one's employment that is directly applicable to the business. Do they automatically have claim over it? Can you not make any changes while with that employer?
This basically only protects employees of small businesses. The language makes it seem like anyone working at a FAANG definitely still can't invent anything.
