Roughly speaking it took 2 years from application of the Nunchi and microsignet patents to eventually being granted. Nunchi has been granted for 3 years and MS for 2(within 2-3 months). Following that math, it could easily be 4 to 5 years or longer before seeing any income from Pluto if at all. Hearing they are working on a new patent does absolutely nothing for me personally as there is no way that I will own this stock in 4 to 5 years. More of a concern is with the flash income very long in the tooth, unless Nunchi and/or MS can generate some decent income in the not too distant future, the company will probably not have enough money to last 4 or 5 more years.IMO
