really, it's hardly worth a comment. they obviously don't mean to acquire IP from your past.
If you're outside California, I would in your position look at how people actually behave, as well as the law. Possibly I would choose to read the non-compete literally and just do the right thing afterward. For example, I might choose not to take a competitive position for the period outlined in the contract, and instead do something slightly different. It's largely a moral thing, I think.
If the non-compete were very broad (no job on Earth for a period of 18 months after termination of employment) I would just ignore it; what are they going to sue me? They wouldn't care.
I don't think I would push back to modify non-compete clauses, and I certainly wouldn't do it in the way I mentioned for IP, however. It depends on jurisdiction. It's quite a cultural thing.
I've known of other companies that didn't have quite "no job on earth" clauses but were pretty serious about enforcing non-competes against anyone taking a similar job with another company. That's pretty restrictive.
That said, in lawsuits, lots of people and organizations tend to get sucked in whether they deserve to be or not. The bottom line is that non-competes have significant chilling effects whether or not lawsuits are ultimately filed.
It's like, if I had signed a non-contract stating I'm now a slave, I'd just ignore that contract. (What I'm saying applies to California.) Certain things just don't have any legal significance. (Such as indentured servitude.)
