Certainly if you are employed by a company then pretty much everything you do of value could belong to the employer. I have this issue because I work in software development and computational research. if I get a good idea for a start-up then I will have difficulty in defending that my employer had no influence over my idea. A friend developed an idea for a new electronics board in his own time while doing a phd, he now has to pay 50% of allrofits to. The university evn. Although the university had nothing to do with his idea.
