The time to have bought ptsc was when it was at .009  9/10 of a penny. PTSC then won a patent infringement suit or 2 and announced a 30 million dollar dividend to share holders and the stock went to 2 bucks. I believe this event happened in 2005 and anyone smart enough to buy a company that looked like it was on its way to bankruptcy made 200 times there money. ( I of course did not buy ). In any case I believe we are at that same infancy level with edig the ptsc infancy level being .009 c.    Time will tell  :-)
