I don't give a crap what you sign... If you come up with an idea, and you do not work on it during company time, who are they to take your idea and profit off of it? Considering that the majority of everyone's day is spent working for someone else, are you not allowed to think anymore until you are off the clock? Put your brain on hold from 9 to 5 in fear that your ideas will get taken? Is that even possible? God forbid while you are at work a good idea should pop into your brain. Whether you work on it during work or not, they own it. That's messed up. But of course they only own the good ideas, not the bad ones.
How about some guy comes up with the idea for a weapon of mass destruction during work hours. Uses it and destroys millions of people. Not his fault, it's the companies invention just because he was working for them when he thought of it. But of course that would never hold water because it wouldn't benefit the copmpany. Only when something benefits them does it hold water, no matter how intrusive and unfair it is to the individual. Basically if they want it they take it. That's what it comes down to.
Coporations run the US now. No such thing as individual rights. Our country is Utilitarian. Whatever brings the most people happiness. So basically stealing one guys idea makes him unhappy, but brings the corporation happiness which is more important than just one person being happy. Sounds like a ruthless street gang to me.
