Nothing has changed, and nothing will change until one day the bag holders find out that there is no bid on the stock, nor furniture in the REFR office (if there is any right now). This is an old scam story; it goes back to the earliest stock scams. As always, the idiots holding the shares think that "this time it is different."
It is the job of the stock scam perpetrator to get prospective buyers to believe that they should look into the future, "not into the rear view mirrors." This metaphor has been used since the first rear view mirrors were mounted on automobiles. It sounds so "forward looking."
I also don't believe that since I first shorted this fraud when it was 20 or so more than ten years ago that any of the penny stock scammers have ever quoted the REFR SEC filing. The reason for that is simply that those filings, unlike the hype on this board, have potentially severe liability for fraudulent claims. Hence they tell the story very clearly of a company with no sales, no customers, and the possibility that that reality will not change.
The fraudsters by now are certain that there are still enough lazy investors who will not even look at the SEC filings.
