Ann: Zoono Group Signs Significant Deal for China, page-39

Also and somewhat surprisingly KFC and Coca Cola don't have patents for the reasons you mentioned. I think ZNO believe they are so far ahead of the competition that it would take years to match them.

Wait for Chinese NY Feb 2018 when it's launched but human nature and patience is lacking in today's society as we all seem to "want it now"...the MEH generation especially.
As for this recent selling it's down to traders booking their 10-15 cents profits.

Not at all worried as nothing has changed but if it does then I'll change my view.
