Thanks for the reply, I guess I underestimated the tricks companies try. I'd like to see it get tested in court, I want to doubt they would uphold one's ability to sign off one's brain to someone else. I know schools have similar clauses but they usually specify something like "...created by candidate using school equipment or resources", which is understandable. It's interesting to consider that not specifying means you could create something on Mars and the company would own it.

Anyway, I'll shift my stance to lusis'. My eyes would pop out if I ever saw that in a contract offered to me.
