WhatMayCome

Hey fellow Tankers! Give me your input! I contacted one of the individuals on SharkTank on a recent episode as I had an idea that I believed would be a great spin off of their product. They informed me that what I suggested would be feasible and wouldn't be hard to do. They didn't imply that they would begin adding my idea into their products but that it's definitely doable! What would be a prudent way to proceed and to "protect" my idea going forward? Thanks!
