To be clear, many (if not most) of the IP clauses discussed here would still claim to own your personal IP produced while employed EVEN given all those conditions.
As an aside, workers in California have much better protections from this kind of IP overreach by employers, and abiding by the conditions you mention will protect you there, but not necessarily elsewhere. Also, and this really grates me, employers in California will still often include a total IP ownership clause, even though it's nullified by the state law, for reasons I can't fathom - to scare you into not developing your own IP off the clock? Or just in case the law changes? I find it very distasteful.
