I believe California employment law is pretty pro-employee. Mostly if you develop something in your spare time, without using company resources in any way, it is yours.
I think that's why there are lots of startups in california.
In other states, employers in some cases can own everything, up to and including ideas in your head.
I don't know an example state that is the other side of the coin, pro-employer, but maybe texas? (uneducated guess)
This provision is useless if you work for a large company, because it carves out an exception for anything that could be related to your employer’s business.
