An anonymous reader writes: I have decided to leave my current company of 10 years, after seeing a piece of application developed by me not fully utilized to serve and capture market shares, and I would like to start a new business offering a similar service. This app is surprisingly simple, like an online contact form with a few backend logics for distribution purposes, it is not currently patented and possibly cannot be patented. Obviously I will steer clear of using any codes in the existing app, but would there still legal problems by "forking" a similar service given my intimate involvement with the development in its previous life, and what steps should I take to minimize these risks?
