Youve actually gained provisional patent pending looking into the discord. So the documents wont be reviewed by any patent official and you have 12 months to submit the actual documents. Assuming this gets done then you can assume a two year wait for the searches. This takes us to 2023 if you use all the time available in the provisional patent timeline.
I remember Allen and Ashley saying that these were just the first three. So its taken you two years to get to this point on the first three. The patent pending announcement was a clear game from the start. Pump the price so Dave can offload some of his 100million coins.
