I don't know much about nothing...but my guess is the reason Platinum is easing up is because what would they do with the Patents anyway? In my opinion (yes, I know the saying) they faced reality...it's probably better to wait and see instead of owning something they would know zilch to do with. If they saw no light at the end of the tunnell...then they take the patents and sell them to the highest bidder. BUT, they are in the business of making money (as stated by others)...there's probably more money to be made working this thing out.
I'm sure Platinum could sell the IP. How much is it worth, I don't know. There must be company's wanting to get their hands on it. I suspect Platinum is putting pressure on Dais to change their business plan. I hope they are for sale and have a suitor. Killing the offering would give protection for a suitor, to insure the shares outstanding do not change. I might be just hopeful, but selling to a company with the capital to get things done, might be the best option.
