I'm in the UK. My employment contract says that anything I create "during [my] employment" that "can be used in the course of the company's business" must be handed over to the company.
Suppose that I write a program in my own time on my own equipment and without direction from anyone at the company, but its the kind of thing that the company might want to buy and use. Can they demand I hand over the copyright?
I understand the normal rules about things created in the course of my work. However I would not be doing that.
The question seems to hinge on the definition of "during employment". Would that be read as "between the time I joined and the time I left, including my leisure time", or would it just be a synonym for "in the course of my work"?
I understand the issues with asking the Net for legal advice, and I've Googled the issue without success. Does anyone have any specific references that address this issue?
