Today in 2001, US Patent 6284244 B1 was issued, an invention of Joseph L. Owades, for his “Mediating the Effects of Alcohol Consumption by Orally Administering Active Dry Yeast.” Here’s the Abstract:
Mediating the effects of alcohol consumption by orally administering an active dry yeast containing alcohol dehydrogenase to a person prior to or simultaneously with consumption of an alcohol-containing beverage to oxidize a portion of the alcohol while it is still in the stomach of the person is described.
This is roughly the same patent, Patent No. 2452476A1: Mediating The Effects Of Alcohol Consumption By Orally Administering Active Dry Yeast, that Owades applied for a patent on and received two years later, in 2003. You can read all about the background of it there.
