In my opinion the Winner deal isn't with diaper manufacturers as it is with the SAP suppliers. So Winner pilot I believe made it a viable technology, coating at the actual suppliers is the real business as more business in coating of SAPs then just diapers.
PLUS that deal or pilot was brought with Medesol and BKTH kicked them to curb, so pilot and the skin irritation testing etc all served its purposes. End of day who knows, FACT BKTH has 3 massive platforms and only a matter of time when they license something else and make is newsworthy...AGAIN, management doesn't own direct common shares, they own PFD D, so its dividend/royalties they seek, so us common holders wait as small floats are hated by "flippers" but loved by those that seek real ROI value.
