It's amusing how much lip service politicians give to the importance of small business, when protecting these two rights would promote them more effectively than any tax break.
And likely if you live in another state this would not be upheld, especially if you were building something wholly unrelated to your employer's product / service.
I'm no lawyer though, so do some research regarding your state's labor laws.
Disclaimer: I'm not a lawyer, but I've been directly involved in issues pertaining to these clauses in the past.
If, on the other hand, your painting business is about creating works of art rather than home improvement... they will leave you alone until some magazine labels you as "the next Picasso" or something. Then they come and sue you into oblivion, since they will out-spend you 50x in court, regardless of who is "right".
But if you patented something related to house painting, they would own that, even if their business is completely unrelated to painting.

Here's at least one interesting quote from the Copyright act of 1976 (assuming we're talking about copyrights not patents):
"A “work made for hire” is a work prepared by an employee within the scope of his or her employment, or a work specially ordered or commissioned for certain uses (including use as a contribution to a collective work), if the parties expressly agree in a written instrument signed by them that the work shall be considered a work made for hire. The employer is the author of a work made for hire."
You might say it's not fair. Yes, it's entirely written for the employers. That's why there's needs for state or Federal labor laws to help the little guys.
I don't know why you want to get around it and trying to give false hope to people. If you want to claim the contract is not enforceable, then you should provide citations for the claim.
There are other alternatives as well, such as working somewhere else (if you think that is the right move), or just couching the idea for awhile.
I think hope is good anyway. Nobody here really wants to be a mindless drone for some company for the rest of their lives. We're all learning here.
My take is that the code doesn't specifically limit the exception to my job function; it's broadly worded to cover the whole of the business. And the UC works on so many areas of research that this essentially means that you can't work anywhere else at the same time if that other work requires any kind of confidentiality.
I tried to engage the IP department at my school about this, but got shuffled around and basically told that there are no exceptions or clarifications. They essentially supported this interpretation I have, and referred me to memos that explain the policy in more detail.
What I can't figure out is this: the policy requires that all students submit potential IP to them for evaluation. That includes IP from summer internships. Why are companies okay with this? In practice, I don't believe many (any?) students do this, but the Director stopped answering my emails when I tried to probe this question more deeply.
