Overly broad applications are rare in germany. If you look at an engineering or research context it's easier to nail down: If you're a researcher the employer pays you for your thought and provides the lab, access to related research, to peers to discuss stuff with etc. Now you've been working on a particularly hard problem and the stroke of genius strikes you at midnight, you get up, work straight for two days and write down the formula you've been working on for years. It's worth a billion dollars. Technically it's during off-hours, so is it yours?
