In reference to the patent: WO2016138171A1
The exact same design had a patent applied for it in 2005 by Eric Vaughn, it was ultimately rejected and has since been abandoned. It should have been accepted, and the only other patent that came close was from 1942, by Carroll G Wells, https://www.google.com/patents/US2315889 My name is Eric Vaughn, and I was not granted the patent. Jake Sullivan was a business partner of mine, along with Don Wildman. I contend that they should not be granted this patent since it has already been invented. Interesting that they claim to be the "inventors."
