For others reading this thread - there are only 8 states that provide restrictions on what these contracts can say regarding what ideas/code are owned by the company. In the other 42, most contracts won't care if you used company resources, or if your work is in an entirely different industry - the employer will own what you make if they're paying you for the month in which you made it. It's not very nice, but it's not like you're being cheated when you choose to take a salary.
