I didn't do any Googling about this, but it seems to me that we would have heard about this remarkable development before it was shared on Facebook. The creator of the "cure" would have held a press conference and put out a bunch of press releases for the attention even before a patent was issued. He wouldn't have had to reveal what the formula was for the cure. The attention would have maybe given him some pull to get the patent issued quickly as well (if true, of course).
