Nowhere on that link does it show any amount paid for anything, and having my own personal business, patents can cost as low as 490 dollars (depending on where you live) but the price is very similar to that of a UE patent. And if they did pay to back a product that can help people, then more power to them, if they make any profit its probably to recoup from backing said product. Either way, after extensively talking to them theyre extremely great people. To each their own opinion. Im ordering symbion next week to try it out.
