IANAL...I have never heard of invention disclosure going past the end of employment. It is universal to require you to cooperate in securing patents and copyrights for things you did while you were employed, even if the filing takes place once you are no longer employed (and these don't seem to have a time limit). Some companies pay for your expenses and time and some don't, or don't in the first draft. That's reasonable--the actual inventor has to sign the patent application, and company should be able to finish the paperwork once you've left. It seems like they would have a hard time claiming they own things you invented on time they didn't pay for. I've signed a non-compete with a small company. They had two competitors that they named in the contract, they were in cities I wouldn't have moved to, anyway, and it didn't close off very many jobs in the universe of jobs. In some states, a non-compete cannot be enforced. It is probably easier to enforce a specific agreement naming particular companies than a generic agreement that says you will give up working anywhere in the industry. In some industries, a non-compete means you can't work for anybody! Practically speaking, they are not going to go through the bother of coming after you for non-work related ideas that they don't know what to do with. But in states where it is allowed, you are giving them an excuse to sue you if you go to work for a competitor, or start up something on your own. It doesn't really matter who wins or loses the suit, it'd still be unpleasant. If you really think you are going to come out with something that threatens their business, and can work on it secretly without anybody noticing, you shouldn't sign it if you're in a state where it can be enforced. If this is just a theoretical concern, it's not worth spending any more time worrying about. I wonder what else is in this agreement.
