IANAL, but a few items you may consider: 1. Did you work on the side project using any of the resources of your current company? If so, they could potentially claim they own the IP. Even still they could try to say that you developed the product knowing there was a need for it within their company therefore they should own the IP. 2. Do you have any sort of employment agreement that stipulates ownership of side projects? 3. Depending on your company they may force you to quit before allowing you to sell a product back to the company. Some companies can be touchy when it comes to potential conflicts of interest like this. 4. Most importantly, I would talk to an attorney before proceeding to discuss any potential pitfulls. A few hundred dollars spent now could potentially save you thousands down the road in legal fees.
