I operate a patent agency in the US and I was wondering if you have patented your idea. If you need a US Patent Agent to represent you. I have a law degree and a PhD and am licensed to the Patent Bar. Please message me if you are interested in pursuing US patent rights - your idea is very cool and US law does not require a prototype in order to obtain a patent. You can see more about me and my credentials at iancoyle.net. Thank you, Ian Coyle, JD, PhD.
