I file for the first of a series of patents with the P5 prototype. It is a major milestone. I’m now Pat Pending, like the famous professor on The Wacky Races. Nearing the limit of my own engineering capabilities I arrange to meet some industrial designers. Two different design studios tell me they’ve seen nothing like it and it's the biggest commercial idea they have seen from an individual inventor. I'm really starting to think I might be onto something.
