I am currently employed as a director of a UK-based software development company, but am considering setting up a new company for an idea that I conceived recently. My idea is software-based but for a completely different business area to that of my current company. For the past few months I have been exploring the idea in my own time (evenings, weekends and holidays) using my own hardware and my own software.
My current company's board has stated that they consider this idea to be their property and have threatened to take legal action to enforce this. I disagree with their claim as I developed it in my own time and its business- and technology-areas are completely different from what we currently do. I can also show that the board has known for some time about this, but has never expressed an objection.
I have read snippets from people who suggest that my currently company's claims are unenforceable. Can anyone offer some practical advice or anecdotal evidence that could help me understand where I stand on this issue please?
